+description: Determine the best Anthropic architecture for your project by analyzing requirements and recommending the optimal combination of Skills, Agents, Prompts, and SDK primitives.
+---
+
+# Anthropic Architect
+
+Expert architectural guidance for Anthropic-based projects. Analyze your requirements and receive tailored recommendations on the optimal architecture using Skills, Agents, Subagents, Prompts, and SDK primitives.
+
+## What This Skill Does
+
+Helps you design the right Anthropic architecture for your project by:
+- **Analyzing project requirements** - Understanding complexity, scope, and constraints
+- **Recommending architectures** - Skills vs Agents vs Prompts vs SDK primitives
+- **Applying decision rubrics** - Data-driven architectural choices
+- **Following best practices** - 2025 Anthropic patterns and principles
+- **Progressive disclosure design** - Efficient context management
+- **Security considerations** - Safe, controllable AI systems
+
+## Why Architecture Matters
+
+**Without proper architecture:**
+- Inefficient context usage and high costs
+- Poor performance and slow responses
+- Security vulnerabilities and risks
+- Difficult to maintain and scale
+- Agents reading entire skill contexts unnecessarily
+- Mixed concerns and unclear boundaries
+
+**With engineered architecture:**
+- Optimal context utilization
+- Fast, focused responses
+- Secure, controlled operations
+- Easy to maintain and extend
+- Progressive disclosure of information
+- Clear separation of concerns
+- Scalable and reusable components
+
+## Quick Start
+
+### Analyze Your Project
+
+```
+Using the anthropic-architect skill, help me determine the best
+architecture for: [describe your project]
+
+Requirements:
+- [List your key requirements]
+- [Complexity level]
+- [Reusability needs]
+- [Security constraints]
+```
+
+### Get Architecture Recommendation
+
+The skill will provide:
+1. **Recommended architecture** - Specific primitives to use
+2. **Decision reasoning** - Why this architecture fits
+3. **Implementation guidance** - How to build it
+4. **Best practices** - What to follow
+5. **Example patterns** - Similar successful architectures
+
+## The Four Anthropic Primitives
+
+### 1. Skills (Prompt-Based Meta-Tools)
+
+**What:** Organized folders of instructions, scripts, and resources that agents can discover and load dynamically.
+
+**When to use:**
+- ✅ Specialized domain knowledge needed
+- ✅ Reusable across multiple projects
+- ✅ Complex, multi-step workflows
+- ✅ Reference materials required
+- ✅ Progressive disclosure beneficial
+
+**When NOT to use:**
+- ❌ Simple, one-off tasks
+- ❌ Project-specific logic only
+- ❌ No need for reusability
+
+**Example use cases:**
+- Prompt engineering expertise
+- Design system generation
+- Code review guidelines
+- Domain-specific knowledge (finance, medical, legal)
+
+### 2. Agents/Subagents (Autonomous Task Handlers)
+
+**What:** Specialized agents with independent system prompts, dedicated context windows, and specific tool permissions.
+
+**When to use:**
+- ✅ Complex, multi-step autonomous tasks
+- ✅ Need for isolated context
+- ✅ Different tool permissions required
+- ✅ Parallel task execution
+- ✅ Specialized expertise per task type
+
+**When NOT to use:**
+- ❌ Simple queries or lookups
+- ❌ Shared context required
+- ❌ Sequential dependencies
+- ❌ Resource-constrained environments
+
+**Example use cases:**
+- Code exploration and analysis
+- Test generation and execution
+- Documentation generation
+- Security audits
+- Performance optimization
+

+## Key Principles (2025)
+
+### 1. Progressive Disclosure
+**What:** Show only what's needed, when it's needed.
+
+**Why:** Avoids context limits, reduces costs, improves performance.
+
+**How:** Organize skills with task-based navigation, provide query tools, structure information hierarchically.
+
+### 2. Context as Resource
+**What:** Treat context window as precious, limited resource.
+
+**Why:** Every token counts toward limits and costs.
+
+**How:** Use progressive disclosure, prefer retrieval over dumping, compress aggressively, reset periodically.
+
+### 3. Clear Instructions
+**What:** Explicit, unambiguous directions.
+
+**Why:** Claude 4.x responds best to clarity.
+
+**How:** Be specific, define output format, provide examples, avoid vagueness.
+
+### 4. Security by Design
+**What:** Deny-all default, allowlist approach.
+
+**Why:** Safe, controlled AI systems.
+
+**How:** Limit tool access, require confirmations, audit operations, block dangerous commands.
+
+### 5. Thinking Capabilities
+**What:** Leverage Claude's extended thinking mode.
+
+**Why:** Better results for complex reasoning.
+
+**How:** Request step-by-step thinking, allow reflection after tool use, guide initial thinking.
+
+### 6. Two-Message Pattern
+**What:** Use meta messages for context without UI clutter.
+
+**Why:** Clean UX while providing necessary context.
+
+**How:** Set isMeta: true for system messages, use for skill loading, keep UI focused.

+  description: 'Interacts with proprietary system',
+  execute: async (params) => {
+    // Custom implementation
+    return await proprietarySystem.call(params);
+  }
+};
+
+// Create agent with custom tool
+const agent = new Agent({
+  tools: [customTool, ...standardTools],
+  systemPrompt: 'You are an expert with custom-system access'
+});
+```
+
+**Example: CRM Integration Agent**
+```typescript
+// Custom CRM tools
+const getCRMData: Tool = {
+  name: 'get-crm-data',
+  description: 'Fetch customer data from CRM',
+  execute: async ({ customerId }) => {
+    return await crmAPI.getCustomer(customerId);
+  }
+};
+
+const updateCRMData: Tool = {
+  name: 'update-crm-data',
+  description: 'Update customer data in CRM',
+  execute: async ({ customerId, data }) => {
+    return await crmAPI.updateCustomer(customerId, data);
+  }
+};
+
+// Agent with CRM access
+const crmAgent = new Agent({
+  tools: [getCRMData, updateCRMData],
+  systemPrompt: `You are a CRM assistant with access to customer data.
+    Help users query and update customer information.`
+});
+```
+
+**Usage:**
+```typescript
+const response = await crmAgent.run({
+  task: 'Get customer data for customer ID 12345 and update their email'
+});
+```
+
+**Benefits:**
+- Direct system integration
+- Custom business logic
+- Proprietary data access
+- Fine-grained control
+
+---
+
+### Pattern 10: Custom Feedback Loop
+
+**When to use:**
+- Specific workflow requirements
+- Unique validation logic
+- Custom iteration patterns
+
+**Structure:**
+```typescript
+const customWorkflow = async (task: Task) => {
+  let result;
+  let iterations = 0;
+  const maxIterations = 5;
+
+  while (iterations < maxIterations) {
+    // Step 1: Generate
+    result = await agent.generate(task);
+
+    // Step 2: Custom validation
+    const validation = await customValidator(result);
+
+    // Step 3: Custom decision
+    if (validation.passed) {
+      break; // Success
+    }
+
+    // Step 4: Custom feedback
+    task = customFeedback(task, validation.issues);
+    iterations++;
+  }
+
+  return result;
+};
+```
+
+**Example: Code Generation with Custom Linter**
+```typescript
+const codeGenerationWorkflow = async (spec: Specification) => {
+  let code;
+  let attempt = 0;
+
+  while (attempt < 3) {
+    // Generate code
+    code = await codeAgent.generate(spec);
+
+    // Custom linter validation
+    const lintResults = await customLinter.check(code);
+
+    if (lintResults.errors.length === 0) {
+      // Passed linting
+      break;
+    }
+
+    // Custom feedback loop
+    spec = addLintingFeedback(spec, lintResults.errors);
+    attempt++;
+  }
+
+  // Custom post-processing
+  code = await customFormatter.format(code);
+
+  return code;
+};
+```
+
+**Benefits:**
+- Custom validation logic
+- Specific iteration patterns
+- Business rule enforcement
+- Unique workflows
+
+---
+
+## Progressive Disclosure Patterns
+
+### Pattern 11: Query-Based Disclosure
+
+**When to use:**
+- Large knowledge bases
+- Context optimization critical
+- Task-specific information needed
+
+**Structure:**
+```
+skill/
+├── SKILL.md (high-level overview)
+├── query.sh (interactive query tool)
+├── index.md (navigation)
+└── content/
+    ├── topic_1/
+    │   ├── overview.md (loaded first)
+    │   ├── detailed.md (on demand)
+    │   └── examples.md (when requested)
+    └── topic_2/
+        ├── overview.md
+        ├── detailed.md
+        └── examples.md
+```
+
+**Query Pattern:**
+```bash
+# User queries skill
+"Using skill, how do I implement authentication?"
+
+# Skill loading strategy
+1. Load: index.md (< 500 tokens)
+   → Find relevant topic: authentication
+2. Load: authentication/overview.md (< 1000 tokens)
+   → Provides high-level guidance
+3. If user needs more:
+   Load: authentication/detailed.md
+   → In-depth patterns
+4. If user wants examples:
+   Load: authentication/examples.md
+   → Real code samples
+```
+
+**Benefits:**
+- Minimal initial context
+- Load more as needed
+- Efficient token usage
+- Fast initial response
+
+---
+
+### Pattern 12: Hierarchical Disclosure
+
+**When to use:**
+- Complex topics with depth
+- Progressive learning needed
+- Multiple expertise levels
+
+**Structure:**
+```
+skill/
+├── level_1_basics/
+│   └── (fundamental concepts)
+├── level_2_intermediate/
+│   └── (common patterns)
+├── level_3_advanced/
+│   └── (complex techniques)
+└── level_4_expert/
+    └── (edge cases, optimization)
+```
+
+**Disclosure Flow:**
+```
+User: "Help me with caching"
+
+Skill responds:
+├─ Level 1: Basic caching concepts
+│  User: "I know basics, show me patterns"
+│
+├─ Level 2: Common caching patterns
+│  User: "Show me advanced optimization"
+│
+├─ Level 3: Cache optimization techniques
+│  User: "What about distributed caching?"
+│
+└─ Level 4: Distributed caching strategies
+```
+
+**Benefits:**
+- Tailored to user expertise
+- Prevents overwhelming
+- Progressive depth
+- Efficient learning
+
+---
+
+## Security Patterns
+
+### Pattern 13: Allowlist Security Pattern
+
+**When to use:**
+- Sensitive operations
+- Controlled tool access
+- Security-critical applications
+
+**Structure:**
+```typescript
+const secureAgent = new Agent({
+  tools: allowlistOnly([
+    'Read',      // Safe: read-only
+    'Grep',      // Safe: read-only
+    'Glob',      // Safe: read-only
+  ]),
+  denylist: [
+    'rm -rf',
+    'sudo',
+    'curl',      // Could leak data
+    'wget',      // Could leak data
+  ],
+  confirmations: [
+    'git push',
+    'deployment',
+    'data deletion'
+  ]
+});
+```
+
+**Example: Production Agent**
+```typescript
+const productionAgent = new Agent({
+  name: 'production-agent',
+
+  // Minimal permissions
+  tools: [
+    'Read',          // View configs
+    'Grep',          // Search logs
+  ],
+
+  // Block dangerous operations
+  denylist: [
+    'rm',
+    'delete',
+    'drop',
+    'truncate',
+    'sudo',
+    'chmod',
+    'exec'
+  ],
+
+  // Require confirmation
+  confirmations: [
+    'restart service',
+    'change config',
+    'modify database'
+  ],
+
+  // Audit all operations
+  audit: {
+    enabled: true,
+    logLevel: 'verbose',
+    destination: 'security-log'
+  }
+});
+```
+
+**Benefits:**
+- Deny-all default
+- Explicit permissions
+- Confirmations for sensitive ops
+- Full audit trail
+
+---
+
+### Pattern 14: Defense in Depth
+
+**When to use:**
+- High security requirements
+- Multiple security layers needed
+- Critical systems
+
+**Structure:**
+```
+Security Layers:
+
+Layer 1: Tool Allowlist
+  → Only approved tools
+
+Layer 2: Command Validation
+  → Validate command safety
+
+Layer 3: Confirmation Required
+  → Human approval for sensitive ops
+
+Layer 4: Sandbox Execution
+  → Isolated environment
+
+Layer 5: Audit Logging
+  → Full operation trail
+
+Layer 6: Rollback Capability
+  → Undo mechanism
+```
+
+**Example: Financial System Agent**
+```typescript
+const financialAgent = new Agent({
+  // Layer 1: Tool Allowlist
+  tools: allowlistOnly(['Read', 'Grep']),
+
+  // Layer 2: Command Validation
+  preExecute: async (command) => {
+    return await securityValidator.validate(command);
+  },
+
+  // Layer 3: Confirmation Required
+  confirmations: 'all',
+
+  // Layer 4: Sandbox
+  sandbox: {
+    enabled: true,
+    isolated: true,
+    networkBlocked: true
+  },
+
+  // Layer 5: Audit
+  audit: {
+    enabled: true,
+    level: 'detailed',
+    retention: '7years',
+    immutable: true
+  },
+
+  // Layer 6: Rollback
+  rollback: {
+    enabled: true,
+    autoSnapshot: true,
+    quickRevert: true
+  }
+});
+```
+
+**Benefits:**
+- Multiple security layers
+- Defense against various threats
+- Compliance ready
+- Maximum security
+
+---

+
+---
+
+## Core Design Principles
+
+### 1. Start Simple, Scale Complexity
+
+**Principle:** Always begin with the simplest solution that meets requirements.
+
+**Why:** Avoid over-engineering and unnecessary complexity.
+
+**How:**
+```
+Level 1: Try Direct Prompt
+  └─ Works? → Done
+  └─ Too complex? → Continue
+
+Level 2: Create Skill
+  └─ Works? → Done
+  └─ Needs isolation? → Continue
+
+Level 3: Use Agents
+  └─ Works? → Done
+  └─ Need custom workflow? → Continue
+
+Level 4: SDK Primitives
+  └─ Full control achieved
+```
+
+**Example:**
+```
+Task: Generate code review
+
+❌ Wrong: Immediately build custom SDK agent
+✅ Right: Try direct prompt first
+
+"Review this PR for:
+- Code quality issues
+- Security vulnerabilities
+- Performance concerns"
+
+If inconsistent → Create code-review skill
+If too complex → Use agent with multiple phases
+```
+
+---
+
+### 2. Progressive Disclosure First
+
+**Principle:** Show only what's needed, when it's needed.
+
+**Why:** Optimize context usage, reduce costs, improve performance.
+
+**How:**
+```
+Structure information hierarchically:
+├── Index/Overview (always load)
+├── Topic Overviews (load on demand)
+├── Detailed Content (load when requested)
+└── Examples (load if needed)
+```
+
+**Anti-Pattern:**
+```markdown
+❌ DON'T: Dump entire skill into context
+
+skill/
+└── SKILL.md (100KB of everything)
+    → Context overload
+    → Slow responses
+    → High costs
+```
+
+**Best Practice:**
+```markdown
+✅ DO: Structure for progressive disclosure
+
+skill/
+├── SKILL.md (overview, 2KB)
+├── index.md (navigation, 1KB)
+└── topics/
+    ├── topic_1/
+    │   ├── overview.md (1KB)
+    │   └── details.md (loaded on request)
+    └── topic_2/
+        ├── overview.md (1KB)
+        └── details.md (loaded on request)
+
+Total initial load: ~4KB vs 100KB
+```
+
+---
+
+### 3. Context as Precious Resource
+
+**Principle:** Treat every token as valuable and limited.
+
+**Why:** Context windows have limits and costs.
+
+**Context Budget:**
+```
+Claude 4.x: 200K tokens
+- Reserve: 50K for responses
+- Available: 150K for context
+- Budget wisely!
+```
+
+**Best Practices:**
+- ✅ Load only necessary information
+- ✅ Summarize large outputs
+- ✅ Use progressive disclosure
+- ✅ Reset context periodically
+- ✅ Compress repeated information
+- ❌ Don't dump raw logs
+- ❌ Don't load unused references
+- ❌ Don't repeat information
+
+---
+
+### 4. Clear, Explicit Instructions
+
+**Principle:** Claude 4.x responds best to unambiguous direction.
+
+**Why:** Reduces errors, improves consistency, better results.
+
+**Comparison:**
+```
+❌ Vague:
+"Make the code better"
+
+✅ Clear:
+"Refactor this function to:
+1. Extract magic numbers to constants
+2. Add type annotations
+3. Improve variable names for clarity
+4. Add error handling for edge cases
+Format: Return only the refactored code"
+```
+
+**Template:**
+```
+<instructions>
+TASK: [Clear task definition]
+
+REQUIREMENTS:
+- [Specific requirement 1]
+- [Specific requirement 2]
+- [Specific requirement 3]
+
+OUTPUT FORMAT:
+[Exact format expected]
+
+CONSTRAINTS:
+- [Constraint 1]
+- [Constraint 2]
+</instructions>
+
+<examples>
+[2-3 examples showing desired pattern]
+</examples>
+```
+
+---
+
+### 5. Security by Design
+
+**Principle:** Deny-all default, allowlist approach.
+
+**Why:** Safe, controlled AI systems.
+
+**Security Checklist:**
+- [ ] Minimal tool permissions
+- [ ] Allowlist approved tools only
+- [ ] Deny dangerous commands
+- [ ] Require confirmations for sensitive ops
+- [ ] Audit all operations
+- [ ] Implement rollback capability
+- [ ] Validate all inputs
+- [ ] Sandbox execution when possible
+
+**Default Agent Security:**
+```typescript
+const secureAgent = new Agent({
+  // Deny-all default
+  tools: [],
+
+  // Explicitly allow minimal tools
+  allowlist: [
+    'Read',   // Read-only
+    'Grep',   // Search-only
+    'Glob'    // Find-only
+  ],
+
+  // Block dangerous operations
+  denylist: [
+    'rm -rf',
+    'sudo',
+    'exec',
+    'eval'
+  ],
+
+  // Require confirmation
+  confirmations: [
+    'git push',
+    'deployment',
+    'data modification'
+  ]
+});
+```
+
+---
+
+## Progressive Disclosure
+
+### Pattern: Query-Based Disclosure
+
+**Best Practice:**
+```
+skill/
+├── SKILL.md
+│   Content: High-level overview
+│   Size: < 2KB
+│   Purpose: Introduce skill capabilities
+│
+├── index.md
+│   Content: Navigation/TOC
+│   Size: < 1KB
+│   Purpose: Guide to available topics
+│
+└── content/
+    └── topic/
+        ├── overview.md (load first)
+        ├── details.md (load on demand)
+        └── examples.md (load when requested)
+```
+
+**Loading Strategy:**
+```
+1. Initial load: SKILL.md + index.md (~3KB)
+2. User asks about "authentication"
+3. Load: authentication/overview.md (~1KB)
+4. User needs details
+5. Load: authentication/details.md (~3KB)
+6. User wants examples
+7. Load: authentication/examples.md (~2KB)
+
+Total: 9KB loaded vs 50KB if dumped all at once
+Savings: 82% context reduction
+```
+
+---
+
+### Pattern: Hierarchical Expertise
+
+**Best Practice:**
+```
+expertise/
+├── by_task/
+│   ├── authentication.md
+│   ├── api_design.md
+│   └── testing.md
+├── by_language/
+│   ├── typescript.md
+│   ├── python.md
+│   └── rust.md
+├── by_pattern/
+│   ├── repository.md
+│   └── factory.md
+└── quick_reference/
+    └── cheatsheet.md
+```
+
+**Query Examples:**
+```
+"How to implement auth?" → Load: by_task/authentication.md
+"TypeScript style guide?" → Load: by_language/typescript.md
+"Repository pattern?" → Load: by_pattern/repository.md
+"Quick naming conventions?" → Load: quick_reference/cheatsheet.md
+```
+
+---
+
+## Context Management
+
+### Best Practice 1: Periodic Context Reset
+
+**Why:** Long sessions accumulate irrelevant context.
+
+**When to reset:**
+- After completing major task
+- Context feels "bloated"
+- Responses become slower
+- Approaching token limits
+
+**How:**
+```
+Option 1: New conversation
+- Start fresh conversation
+- Provide summary of previous work
+
+Option 2: Explicit reset request
+- Ask Claude to forget irrelevant context
+- Summarize key points to retain
+
+Option 3: Use separate agents
+- Different agents for different tasks
+- Clean contexts per task
+```
+
+---
+
+### Best Practice 2: Summarize, Don't Dump
+
+**Anti-Pattern:**
+```
+❌ DON'T: Dump raw logs
+
+"Here are the test results:"
+[10,000 lines of test output]
+```
+
+**Best Practice:**
+```
+✅ DO: Summarize key information
+
+"Test Results Summary:
+- Total: 1,247 tests
+- Passed: 1,245 (99.8%)
+- Failed: 2
+  - test_auth_token_expiration (line 456)
+  - test_rate_limiting (line 789)
+- Duration: 2m 34s"
+```
+
+---
+
+### Best Practice 3: Compress Repeated Information
+
+**Anti-Pattern:**
+```
+❌ DON'T: Repeat same information
+
+Task 1: "Following these coding standards: [full standards]"
+Task 2: "Following these coding standards: [full standards]"
+Task 3: "Following these coding standards: [full standards]"
+```
+
+**Best Practice:**
+```
+✅ DO: Reference once, use skill
+
+Task 1: Load: coding-standards-skill
+Task 2: "Continue following loaded coding standards"
+Task 3: "Continue following loaded coding standards"
+```
+
+---
+
+## Security & Safety
+
+### Best Practice 1: Minimal Permissions
+
+**Principle:** Grant minimum tools needed for task.
+
+**Example: Code Analysis**
+```typescript
+const analysisAgent = new Agent({
+  tools: [
+    'Read',   // Read code
+    'Grep',   // Search code
+    'Glob'    // Find files
+  ]
+  // NO Write, Edit, Bash, etc.
+});
+```
+
+**Example: Code Modification**
+```typescript
+const codeAgent = new Agent({
+  tools: [
+    'Read',   // Read existing code
+    'Edit'    // Modify code
+  ]
+  // NO Bash (can't execute)
+  // NO full Write (use Edit for safety)
+});
+```
+
+---
+
+### Best Practice 2: Confirmation for Sensitive Operations
+
+**Always require confirmation:**
+- git push
+- Deployment commands
+- Data deletion
+- System modifications
+- API calls to production
+- Database changes
+
+**Implementation:**
+```typescript
+const deployAgent = new Agent({
+  confirmations: [
+    'git push',
+    'npm publish',
+    'kubectl apply',
+    'terraform apply',
+    'aws',
+    'gcloud'
+  ]
+});
+```
+
+---
+
+### Best Practice 3: Audit Logging
+
+**Why:** Track all AI operations for security and debugging.
+
+**What to log:**
+- Tool usage
+- Commands executed
+- Files modified
+- API calls made
+- Errors encountered
+- User confirmations
+
+**Implementation:**
+```typescript
+const auditedAgent = new Agent({
+  audit: {
+    enabled: true,
+    level: 'verbose',
+    includeContext: true,
+    destination: './logs/agent-audit.log',
+    retention: '90days'
+  }
+});
+```
+
+---
+
+## Performance Optimization
+
+### Best Practice 1: Parallel Execution
+
+**When possible, parallelize:**
+
+**Anti-Pattern:**
+```
+❌ Sequential (slow):
+1. Analyze file1.ts → 10s
+2. Analyze file2.ts → 10s
+3. Analyze file3.ts → 10s
+Total: 30s
+```
+
+**Best Practice:**
+```
+✅ Parallel (fast):
+1. Analyze file1.ts ──┐
+2. Analyze file2.ts ──┼→ All run simultaneously
+3. Analyze file3.ts ──┘
+Total: 10s (3x faster)
+```
+
+**Implementation:**
+```
+Launch 3 agents in parallel:
+- Agent 1: file1.ts
+- Agent 2: file2.ts
+- Agent 3: file3.ts
+Aggregate results
+```
+
+---
+
+### Best Practice 2: Cache Frequent Queries
+
+**Pattern:**
+```
+skill/
+└── cache/
+    ├── frequently_asked.md
+    └── common_patterns.md
+```
+
+**Example:**
+```
+Common query: "How to handle errors?"
+
+Instead of processing each time:
+1. Maintain: error_handling.md with comprehensive guide
+2. Query → Immediately load cached response
+3. Fast, consistent responses
+```
+
+---
+
+### Best Practice 3: Optimize Token Usage
+
+**Token Optimization Checklist:**
+- [ ] Use progressive disclosure
+- [ ] Summarize large outputs
+- [ ] Remove redundant information
+- [ ] Compress repeated content
+- [ ] Use shorter variable names in examples
+- [ ] Remove unnecessary whitespace
+- [ ] Reference external docs vs embedding
+
+**Example:**
+```
+❌ High token usage:
+const myVeryLongDescriptiveVariableName = 'value';
+const anotherVeryLongDescriptiveVariableName = 'value';
+
+✅ Optimized:
+const user = 'value';
+const data = 'value';
+// Still clear, fewer tokens
+```
+
+---
+
+## Skill Design
+
+### Best Practice 1: Single Responsibility
+
+**Principle:** Each skill should have one clear purpose.
+
+**Anti-Pattern:**
+```
+❌ DON'T: Mega-skill doing everything
+
+super-skill/
+├── frontend/
+├── backend/
+├── database/
+├── devops/
+└── testing/
+→ Too broad, context overload
+```
+
+**Best Practice:**
+```
+✅ DO: Focused skills
+
+frontend-expert/
+├── components/
+├── styling/
+└── accessibility/
+
+backend-expert/
+├── apis/
+├── services/
+└── databases/
+```
+
+---
+
+### Best Practice 2: Clear Documentation
+
+**Skill Documentation Template:**
+```markdown
+---
+name: skill-name
+description: One-sentence description
+---
+
+# Skill Name
+
+## What This Skill Does
+[2-3 sentences explaining purpose]
+
+## When to Use
+- ✅ Use case 1
+- ✅ Use case 2
+- ❌ Not for use case 3
+
+## Quick Start
+[Simple example]
+
+## Reference Materials
+- file1.md - Description
+- file2.md - Description
+
+## Examples
+[2-3 concrete examples]
+```
+
+---
+
+### Best Practice 3: Version Skills
+
+**Why:** Track changes, enable rollback, communicate updates.
+
+**Structure:**
+```
+skill/
+├── VERSION (e.g., 2.1.0)
+├── CHANGELOG.md
+├── SKILL.md
+└── references/
+```
+
+**CHANGELOG.md:**
+```markdown
+# Changelog
+
+## [2.1.0] - 2025-01-15

+**Principle:** Each agent should have clear, distinct responsibilities.
+
+**Anti-Pattern:**
+```
+❌ DON'T: Monolithic agent doing everything
+
+BigAgent
+├── Explores codebase
+├── Plans changes
+├── Executes changes
+├── Runs tests
+├── Deploys
+└── Monitors
+→ Too much responsibility, hard to debug
+```
+
+**Best Practice:**
+```
+✅ DO: Specialized agents
+
+Main Orchestrator
+├── Explore Agent (read-only)
+├── Plan Agent (planning)
+├── Code Agent (implementation)
+├── Test Agent (validation)
+└── Report Agent (aggregation)
+```
+
+---
+
+### Best Practice 2: Agent Communication Patterns
+
+**Pattern: Parent-Child**
+```
+Main Agent
+│
+├─→ Subagent 1: Task
+│   └─→ Returns: Result
+│
+├─→ Subagent 2: Task
+│   └─→ Returns: Result
+│
+└─→ Main aggregates results
+```
+
+**Pattern: Pipeline**
+```
+Agent 1: Explore
+  └─→ Output: Analysis
+      └─→ Agent 2: Plan
+          └─→ Output: Plan
+              └─→ Agent 3: Execute
+                  └─→ Output: Changes
+```
+
+**Pattern: Parallel Workers**
+```
+Coordinator
+├─┬─ Worker 1 ──┐
+│ ├─ Worker 2 ──┤
+│ ├─ Worker 3 ──┼→ Aggregator → Result
+│ └─ Worker 4 ──┘
+```
+
+---
+
+### Best Practice 3: Error Handling in Agents
+
+**Principle:** Graceful failure and recovery.
+
+**Pattern:**
+```typescript
+const resilientAgent = async (task) => {
+  try {
+    const result = await agent.run(task);
+    return result;
+  } catch (error) {
+    // Log error
+    logger.error('Agent failed', error);
+
+    // Attempt recovery
+    if (isRecoverable(error)) {
+      return await retryWithBackoff(agent, task);
+    }
+
+    // Fallback strategy
+    return await fallbackStrategy(task);
+  }
+};
+```
+
+---
+
+## Testing & Validation
+
+### Best Practice 1: Test Skills
+
+**What to test:**
+- Skill loads correctly
+- References are accessible
+- Examples are valid
+- Scripts execute successfully
+
+**Example:**
+```bash
+#!/bin/bash
+# test_skill.sh
+
+echo "Testing skill: $1"
+
+# Test 1: Skill file exists
+if [ ! -f "$1/SKILL.md" ]; then
+  echo "❌ SKILL.md not found"
+  exit 1
+fi
+
+# Test 2: References are valid
+for ref in $1/references/*.md; do
+  if [ ! -f "$ref" ]; then
+    echo "❌ Reference missing: $ref"
+    exit 1
+  fi
+done
+
+# Test 3: Scripts are executable
+for script in $1/scripts/*.sh; do
+  if [ ! -x "$script" ]; then
+    echo "❌ Script not executable: $script"
+    exit 1
+  fi
+done
+
+echo "✅ All tests passed"
+```
+
+---
+
+### Best Practice 2: Validate Agent Output
+
+**Pattern:**
+```typescript
+const validateAgentOutput = async (output) => {
+  // Schema validation
+  if (!matchesSchema(output)) {
+    throw new Error('Invalid output schema');
+  }
+
+  // Business logic validation
+  if (!meetsRequirements(output)) {
+    throw new Error('Output doesn\'t meet requirements');
+  }
+
+  // Safety checks
+  if (containsDangerousContent(output)) {
+    throw new Error('Output contains dangerous content');
+  }
+
+  return output;
+};
+```
+
+---
+
+## Maintenance & Evolution
+
+### Best Practice 1: Regular Skill Updates
+
+**Schedule:**
+- Monthly: Review and update examples
+- Quarterly: Major updates for new patterns
+- Yearly: Comprehensive review and restructure
+
+**Update Checklist:**
+- [ ] New patterns added
+- [ ] Deprecated patterns removed
+- [ ] Examples updated for current versions
+- [ ] Documentation improved
+- [ ] User feedback incorporated
+- [ ] Version bumped
+- [ ] Changelog updated
+
+---
+
+### Best Practice 2: Deprecation Strategy
+
+**When deprecating:**
+```markdown
+## [3.0.0] - 2025-06-01
+
+### Deprecated
+⚠️ OLD PATTERN (Deprecated, remove in 4.0.0):
+[Old pattern example]
+
+✅ NEW PATTERN (Use instead):
+[New pattern example]
+
+Migration guide: See MIGRATION.md
+```
+
+**Deprecation Timeline:**
+1. Announce deprecation (version N)
+2. Maintain both patterns (version N+1)
+3. Remove old pattern (version N+2)
+
+---
+
+## Cost Optimization
+
+### Best Practice 1: Token Efficiency
+
+**Strategies:**
+- Use progressive disclosure (load less)
+- Summarize outputs (fewer tokens)
+- Cache frequent queries (reuse)
+- Compress repeated content (deduplicate)
+- Choose smaller models when possible (Haiku vs Sonnet)
+
+**Example:**
+```
+Task: Simple syntax error fix
+
+❌ Expensive: Use Sonnet for everything
+Cost: $X per request
+
+✅ Optimized: Use Haiku for simple tasks
+Cost: $X/5 per request
+Savings: 80%
+```
+
+---
+
+### Best Practice 2: Model Selection
+
+**Choose model based on complexity:**
+
+**Haiku (Fast, Cheap):**
+- Simple queries
+- Straightforward tasks
+- Well-defined operations
+- Cost-sensitive applications
+
+**Sonnet (Balanced):**
+- Medium complexity
+- Most general tasks
+- Good balance of capability/cost
+- Default choice
+
+**Opus (Powerful, Expensive):**
+- Complex reasoning
+- Critical tasks
+- High-stakes decisions
+- Quality over cost
+
+---
+
+## Summary Checklist

+# Advanced Prompt Engineering Techniques
+
+Advanced techniques for optimizing Claude prompts for complex use cases.
+
+## Few-Shot Prompting (Learning from Examples)
+
+**What it is:** Provide examples of inputs and desired outputs to teach Claude the pattern
+
+**Why it works:** Claude learns from examples better than from abstract instructions alone
+
+**When to use:**
+- Complex output formats
+- Specific writing styles
+- Pattern recognition tasks
+- Consistent formatting needs
+
+**Best practices:**
+- Use 2-5 diverse examples
+- Include edge cases
+- Ensure examples are accurate
+- Use XML tags to structure examples
+
+**Example:**
+```xml
+<instructions>
+Extract product information in the specified format.
+</instructions>
+
+<examples>
+<example>
+<input>iPhone 15 Pro - $999 - 128GB storage, titanium finish</input>
+<output>
+Product: iPhone 15 Pro
+Price: $999
+Features: 128GB storage, titanium finish
+</output>
+</example>
+
+<example>
+<input>MacBook Air M2 chip starting at $1,199</input>
+<output>
+Product: MacBook Air M2
+Price: $1,199
+Features: M2 chip
+</output>
+</example>
+</examples>
+
+<input>
+[new product description]
+</input>
+```
+
+---
+
+## Role Prompting
+
+**What it is:** Assign Claude a specific role or persona to guide its responses
+
+**Why it works:** Provides context for appropriate tone, knowledge level, and approach
+
+**When to use:**
+- Domain-specific tasks
+- Specific communication styles
+- Educational content
+- Professional contexts
+
+**Examples:**
+
+```
+You are a senior Python developer with 10 years of experience.
+Review this code and provide feedback as you would to a junior developer.
+Focus on best practices, performance, and maintainability.
+
+<code>
+[code here]
+</code>
+```
+
+```
+You are a patient elementary school math teacher.
+Explain fractions to a 7-year-old using simple language and fun examples.
+```
+
+---
+
+## Context Engineering
+
+**What it is:** Carefully managing what information goes into the prompt
+
+**Why it works:** LLMs have finite attention - every token counts
+
+**Key principles:**
+- Treat context as a finite resource
+- Use "just-in-time" data loading
+- Progressive disclosure over dump-all
+- Prioritize signal over noise
+
+**Best practices:**
+- Start minimal, add based on failures
+- Use structural organization (XML/Markdown headers)
+- Remove redundant information
+- Find the right altitude (specific but flexible)
+
+**Example - Bad:**
+```
+[Dumps entire 10-page documentation]
+
+Answer this specific question about one feature.
+```
+
+**Example - Good:**
+```xml
+<instructions>
+Answer the user's question using only the relevant documentation below.
+</instructions>
+
+<relevant_docs>
+[Only the 2 paragraphs about the specific feature]
+</relevant_docs>
+
+<question>
+How do I configure feature X?
+</question>
+```
+
+---
+
+## Long-Form Task Prompting
+
+**What it is:** Breaking complex tasks into clear steps
+
+**Why it works:** Reduces ambiguity and improves consistency
+
+**When to use:**
+- Multi-step processes
+- Complex analysis tasks
+- Content generation workflows
+- Production systems
+
+**Example:**
+```xml
+<task>
+Generate a comprehensive blog post about topic X.
+</task>
+
+<steps>
+1. Research: Identify 3 key points about the topic
+2. Structure: Create an outline with introduction, 3 main sections, conclusion
+3. Write: Develop each section with examples and data
+4. Optimize: Add SEO-friendly headers and meta description
+5. Review: Check for accuracy, clarity, and completeness
+</steps>
+
+<requirements>
+- Length: 1500-2000 words
+- Tone: Professional but approachable
+- Include: Statistics, examples, actionable takeaways
+- Audience: Intermediate practitioners
+</requirements>
+```
+
+---
+
+## Prompt Chaining
+
+**What it is:** Breaking a complex task into a sequence of simpler prompts
+
+**Why it works:** Each step focuses on one thing, improving quality
+
+**When to use:**
+- Very complex tasks
+- When intermediate verification is needed
+- Multi-stage processing
+- Quality-critical applications
+
+**Example workflow:**
+1. **Analysis prompt:** "Extract key themes from this document"
+2. **Synthesis prompt:** "Using these themes, create an outline"
+3. **Generation prompt:** "Using this outline, write the full content"
+4. **Review prompt:** "Review and improve this content"
+
+---
+
+## Output Control Techniques
+
+### Controlling Length
+
+**Specify exact targets:**
+```
+Write a 250-word summary (aim for 240-260 words)
+```
+
+**Use structural limits:**
+```
+Summarize in exactly 3 bullet points, each 1-2 sentences
+```
+
+### Controlling Format
+
+**Use prefilling:**
+```
+Assistant: {
+  "status":
+```
+
+**Specify structure:**
+```xml
+<output_format>
+Return markdown with:
+## Summary
+[2-3 sentences]
+
+## Key Points
+- [point 1]
+- [point 2]
+- [point 3]
+
+## Recommendation
+[1 paragraph]
+</output_format>
+```
+
+### Controlling Tone
+
+**Be specific:**
+```
+Tone: Technical but accessible
+- Use industry terminology
+- Explain complex concepts simply
+- Professional yet conversational
+- Avoid jargon where possible
+```
+
+---
+
+## Meta-Prompting
+
+**What it is:** Having Claude help improve or generate prompts
+
+**Use cases:**
+- Generating prompt variations
+- Improving existing prompts
+- Creating test cases
+- Prompt optimization
+
+**Example:**
+```
+I want to create a prompt that extracts structured data from resumes.
+
+Help me design an effective prompt that:
+1. Uses XML tags for structure
+2. Includes 2 examples
+3. Specifies exact JSON output format
+4. Handles edge cases (missing information)
+
+Show me the complete prompt.
+```
+
+---
+
+## Testing and Iteration
+
+**Empirical approach:**
+1. Start with a baseline prompt
+2. Test with diverse inputs
+3. Identify failure modes
+4. Add examples or constraints
+5. Re-test and measure improvement
+6. Iterate until quality threshold met
+
+**Key metrics:**
+- Accuracy on test cases
+- Consistency across runs
+- Edge case handling
+- Token efficiency
+- Response time
+
+**Best practice:** Test-driven prompt development
+- Create evaluation dataset first
+- Define success criteria
+- Iterate systematically
+- Measure objectively

+# Common Prompt Engineering Mistakes
+
+Learn from these common pitfalls to create better prompts.
+
+## Mistake 1: Being Too Vague
+
+❌ **Problem:**
+```
+Write something about AI
+```
+
+**Why it fails:**
+- No clear scope or direction
+- Undefined output format
+- Unknown target audience
+- No length specification
+
+✅ **Solution:**
+```
+Write a 500-word introduction to large language models for software developers.
+
+Include:
+- What LLMs are and how they work (high-level)
+- 3 practical use cases in software development
+- 1 code example of API usage
+- Limitations to be aware of
+
+Tone: Technical but accessible
+Format: Markdown with headers
+```
+
+---
+
+## Mistake 2: Instruction Confusion
+
+❌ **Problem:**
+```
+Here is some text about Python. It talks about lists and dictionaries.
+Can you make it better and also add examples? Use clear language.
+```
+
+**Why it fails:**
+- Instructions mixed with content
+- Unclear what "better" means
+- No structural separation
+
+✅ **Solution:**
+```xml
+<instructions>
+Improve the following text by:
+1. Adding 2 code examples (one for lists, one for dictionaries)
+2. Simplifying complex sentences
+3. Adding subheadings for each topic
+</instructions>
+
+<text_to_improve>
+[original text here]
+</text_to_improve>
+
+<target_audience>
+Beginner Python developers
+</target_audience>
+```
+
+---
+
+## Mistake 3: No Examples (When Needed)
+
+❌ **Problem:**
+```
+Extract entities from customer support tickets in a structured format.
+```
+
+**Why it fails:**
+- "Structured format" is ambiguous
+- No clarity on what entities matter
+- Different interpretations possible
+
+✅ **Solution:**
+```xml
+<instructions>
+Extract entities from customer support tickets.
+</instructions>
+
+<examples>
+<example>
+<input>
+My order #12345 never arrived. I contacted support@example.com but no response.
+</input>
+<output>
+{
+  "order_id": "12345",
+  "issue_type": "delivery",
+  "contact_method": "email",
+  "email": "support@example.com"
+}
+</output>
+</example>
+</examples>
+
+<input>
+[new ticket]
+</input>
+```
+
+---
+
+## Mistake 4: Prompt Too Long
+
+❌ **Problem:**
+```
+[5000 words of background information]
+[500 words of instructions]
+[1000 words of examples]
+
+Now answer this simple question: What is the capital of France?
+```
+
+**Why it fails:**
+- Wastes tokens on irrelevant context
+- Dilutes important information
+- Slower and more expensive
+- May confuse the model
+
+✅ **Solution:**
+```
+What is the capital of France?
+```
+
+**Principle:** Use minimum necessary context
+
+---
+
+## Mistake 5: Not Controlling Output Format
+
+❌ **Problem:**
+```
+Give me the user's information from this text.
+```
+
+**Result:** Unpredictable format - might be prose, bullet points, or inconsistent structure
+
+✅ **Solution:**
+```xml
+<instructions>
+Extract user information and return as JSON.
+</instructions>
+
+<input>
+[text here]
+</input>
+
+<output_format>
+{
+  "name": string,
+  "email": string | null,
+  "phone": string | null
+}

+# Core Prompt Engineering Techniques
+
+Anthropic's official prompt engineering techniques for Claude AI models.
+
+## 1. Be Clear and Direct
+
+**What it is:** Provide explicit, unambiguous instructions
+
+**Why it works:** Claude 4.x models are trained for precise instruction following
+
+**When to use:**
+- Any prompt where clarity matters
+- Production systems requiring consistent output
+- Complex tasks with specific requirements
+
+**How to apply:**
+- State exactly what you want
+- Specify format, length, and tone
+- Avoid vague or ambiguous language
+- Include specific constraints and requirements
+
+**Examples:**
+
+❌ **Bad:**
+```
+Tell me about Python
+```
+
+✅ **Good:**
+```
+Write a 300-word explanation of Python's list comprehensions for intermediate developers.
+Include:
+- 3 practical examples
+- Performance considerations
+- Common pitfalls to avoid
+```
+
+---
+
+## 2. Use XML Tags for Structure
+
+**What it is:** Organize prompts with XML tags like `<instructions>`, `<example>`, `<context>`
+
+**Why it works:** Claude was trained with XML tags, naturally recognizing them as structural elements
+
+**When to use:**
+- Separating data from instructions
+- Complex prompts with multiple sections
+- When working with variable content
+- Production systems requiring clear boundaries
+
+**Common tags:**
+- `<instructions>` - Main task description
+- `<example>` - Few-shot examples
+- `<context>` - Background information
+- `<document>` - Input data to process
+- `<output_format>` - Expected result format
+- `<constraints>` - Limitations and rules
+
+**Example:**
+```xml
+<instructions>
+Analyze the customer review below and extract structured sentiment data.
+</instructions>
+
+<review>
+The product arrived damaged and customer service was unhelpful.
+</review>
+
+<output_format>
+Return JSON with:
+- "sentiment": "positive" | "negative" | "neutral"
+- "confidence": 0.0 to 1.0
+- "key_issues": array of strings
+</output_format>
+```
+
+---
+
+## 3. Chain of Thought (CoT)
+
+**What it is:** Ask Claude to think step-by-step before providing final answer
+
+**Why it works:** Breaking down problems leads to more accurate, nuanced, and reliable responses
+
+**When to use:**
+- Math and logical reasoning problems
+- Complex analysis tasks
+- Multi-step processes
+- When accuracy is critical
+- Debugging and troubleshooting
+
+**How to apply:**
+- Add "Think step by step" to your prompt
+- Request reasoning in `<thinking>` tags
+- Ask Claude to show its work
+- Guide the thinking process with specific steps
+
+**Examples:**
+
+**Basic CoT:**
+```
+Solve this problem step by step:
+
+<problem>
+A store sells apples for $2 each. If you buy 5 or more, you get 20% off.
+How much do 7 apples cost?
+</problem>
+
+Think through this step by step, showing your work.
+```
+
+**Structured thinking:**
+```
+Analyze this code for bugs. Use the following process:
+
+<thinking>
+1. Read and understand the code structure
+2. Identify potential issues
+3. Assess severity of each issue
+4. Recommend fixes
+</thinking>
+
+<code>
+[code here]
+</code>
+```
+
+---
+
+## 4. Prefilling Claude's Response
+
+**What it is:** Provide the beginning of Claude's response to guide output format and style
+
+**Why it works:** Immediately directs the response in the desired direction

+description: Design iOS apps following Apple's Human Interface Guidelines. Generate native components, validate designs, and ensure accessibility compliance for iPhone, iPad, and Apple Watch.
+---
+
+# Apple HIG Designer
+
+Design beautiful, native iOS apps following Apple's Human Interface Guidelines (HIG). Create accessible, intuitive interfaces with native components, proper typography, semantic colors, and Apple's design principles.
+
+## What This Skill Does
+
+Helps you design and build iOS apps that feel native and follow Apple's guidelines:
+- **Generate iOS Components** - Create SwiftUI and UIKit components
+- **Validate Designs** - Check compliance with Apple HIG
+- **Ensure Accessibility** - VoiceOver, Dynamic Type, color contrast
+- **Apply Design Principles** - Clarity, Deference, Depth
+- **Use Semantic Colors** - Automatic dark mode support
+- **Implement Typography** - San Francisco font system
+- **Follow Spacing** - 8pt grid system and safe areas
+
+## Apple's Design Principles
+
+### 1. Clarity
+
+**Make content clear and focused.**
+
+Text is legible at every size, icons are precise and lucid, adornments are subtle and appropriate, and a focus on functionality drives the design.
+
+```swift
+// ✅ Clear, focused content
+Text("Welcome back, Sarah")
+    .font(.title)
+    .foregroundColor(.primary)
+
+// ❌ Unclear, cluttered
+Text("Welcome back, Sarah!!!")
+    .font(.title)
+    .foregroundColor(.red)
+    .background(.yellow)
+    .overlay(Image(systemName: "star.fill"))
+```
+
+### 2. Deference
+
+**UI helps people understand and interact with content, but never competes with it.**
+
+The interface defers to content, using a light visual treatment that keeps focus on the content and gives the content room to breathe.
+
+```swift
+// ✅ Content-focused
+VStack(alignment: .leading, spacing: 8) {
+    Text("Article Title")
+        .font(.headline)
+    Text("Article content goes here...")
+        .font(.body)
+        .foregroundColor(.secondary)
+}
+.padding()
+
+// ❌ Distracting UI
+VStack(spacing: 8) {
+    Text("Article Title")
+        .font(.headline)
+        .foregroundColor(.white)
+        .background(.blue)
+        .border(.red, width: 3)
+}
+```
+
+### 3. Depth
+
+**Visual layers and realistic motion convey hierarchy and help people understand relationships.**
+
+Distinct visual layers and realistic motion impart vitality and facilitate understanding. Touch and discoverability heighten delight and enable access to functionality without losing context.
+
+```swift
+// ✅ Clear depth hierarchy
+ZStack {
+    Color(.systemBackground)
+
+    VStack {
+        // Card with elevation
+        CardView()
+            .shadow(radius: 8)
+    }
+}
+
+// Using blur for depth
+Text("Content")
+    .background(.ultraThinMaterial)
+```
+
+## iOS UI Components
+
+### Navigation Patterns
+
+#### 1. Navigation Bar
+
+**Top bar for navigation and actions.**
+
+```swift
+NavigationStack {
+    List {
+        Text("Item 1")
+        Text("Item 2")
+    }
+    .navigationTitle("Title")
+    .navigationBarTitleDisplayMode(.large)
+    .toolbar {
+        ToolbarItem(placement: .navigationBarTrailing) {
+            Button("Add") {
+                // Action
+            }
+        }
+    }
+}
+```
+
+**Guidelines:**
+- Use large titles for top-level views
+- Use inline titles for detail views
+- Keep actions relevant to current context
+- Maximum 2-3 toolbar items
+
+#### 2. Tab Bar
+
+**Bottom navigation for top-level destinations.**
+
+```swift
+TabView {
+    HomeView()
+        .tabItem {
+            Label("Home", systemImage: "house")
+        }
+
+    SearchView()
+        .tabItem {
+            Label("Search", systemImage: "magnifyingglass")
+        }
+
+    ProfileView()
+        .tabItem {
+            Label("Profile", systemImage: "person")
+        }
+}
+```
+
+**Guidelines:**
+- 3-5 tabs maximum
+- Use SF Symbols for icons
+- Labels should be concise (one word)
+- Never hide or disable tabs
+- Don't use tab bar with toolbar in same view
+
+#### 3. List
+
+**Scrollable list of items.**
+
+```swift
+List {
+    Section("Today") {
+        ForEach(items) { item in
+            NavigationLink {
+                DetailView(item: item)
+            } label: {
+                HStack {
+                    Image(systemName: item.icon)
+                        .foregroundColor(.accentColor)
+                    Text(item.title)
+                }
+            }
+        }
+    }
+}
+.listStyle(.insetGrouped)
+```
+
+**List Styles:**
+- `.plain` - Edge-to-edge rows
+- `.insetGrouped` - Rounded, inset sections (iOS default)
+- `.sidebar` - For navigation sidebars
+
+#### 4. Sheet (Modal)
+
+**Present content modally.**
+
+```swift
+struct ContentView: View {
+    @State private var showSheet = false
+
+    var body: some View {
+        Button("Show Details") {
+            showSheet = true
+        }
+        .sheet(isPresented: $showSheet) {
+            DetailView()
+                .presentationDetents([.medium, .large])
+        }
+    }
+}
+```
+
+**Sheet Detents:**
+- `.medium` - Half screen
+- `.large` - Full screen
+- Custom heights available
+
+### Form Controls
+
+#### 1. Button
+
+**Primary action control.**
+
+```swift
+// Filled button (primary action)
+Button("Continue") {
+    // Action
+}
+.buttonStyle(.borderedProminent)
+
+// Bordered button (secondary action)
+Button("Cancel") {
+    // Action
+}
+.buttonStyle(.bordered)
+
+// Plain button (tertiary action)
+Button("Learn More") {
+    // Action
+}
+.buttonStyle(.plain)
+```
+
+**Button Hierarchy:**
+1. **Prominent** - Primary action (one per screen)
+2. **Bordered** - Secondary actions
+3. **Plain** - Tertiary actions, links
+
+**Guidelines:**
+- Minimum tap target: 44x44 points
+- Use verbs for button labels
+- Make destructive actions require confirmation
+
+#### 2. TextField
+
+**Text input control.**
+
+```swift
+@State private var username = ""
+@State private var password = ""
+
+VStack(alignment: .leading, spacing: 16) {
+    // Standard text field
+    TextField("Username", text: $username)
+        .textFieldStyle(.roundedBorder)
+        .textContentType(.username)
+        .textInputAutocapitalization(.never)
+        .autocorrectionDisabled()
+
+    // Secure field
+    SecureField("Password", text: $password)
+        .textFieldStyle(.roundedBorder)
+        .textContentType(.password)
+}
+```
+
+**Text Content Types:**
+- `.username` - Username field
+- `.password` - Password field
+- `.emailAddress` - Email field
+- `.telephoneNumber` - Phone number
+- `.creditCardNumber` - Credit card
+
+#### 3. Toggle
+
+**Boolean control (switch).**
+
+```swift
+@State private var isEnabled = false
+
+Toggle("Enable notifications", isOn: $isEnabled)
+    .toggleStyle(.switch)
+```
+
+**Guidelines:**
+- Label describes what the toggle controls
+- Effect should be immediate
+- Use for binary choices only
+
+#### 4. Picker
+
+**Selection control.**
+
+```swift
+@State private var selectedSize = "Medium"
+let sizes = ["Small", "Medium", "Large"]
+
+// Menu style
+Picker("Size", selection: $selectedSize) {
+    ForEach(sizes, id: \.self) { size in
+        Text(size).tag(size)
+    }
+}
+.pickerStyle(.menu)
+
+// Segmented style (for 2-5 options)
+Picker("Size", selection: $selectedSize) {
+    ForEach(sizes, id: \.self) { size in
+        Text(size).tag(size)
+    }
+}
+.pickerStyle(.segmented)
+```
+
+**Picker Styles:**
+- `.menu` - Dropdown menu (default)
+- `.segmented` - Segmented control (2-5 options)
+- `.wheel` - Scrollable wheel
+- `.inline` - Inline list (in forms)
+
+### Cards and Containers
+
+#### Card View
+
+```swift
+struct CardView: View {
+    var body: some View {
+        VStack(alignment: .leading, spacing: 12) {
+            Text("Title")
+                .font(.headline)
+
+            Text("Description goes here with some details about the content.")
+                .font(.subheadline)
+                .foregroundColor(.secondary)
+                .lineLimit(2)
+
+            Spacer()
+
+            Button("Action") {
+                // Action
+            }
+            .buttonStyle(.borderedProminent)
+        }
+        .padding()
+        .frame(width: 300, height: 200)
+        .background(Color(.systemBackground))
+        .cornerRadius(12)
+        .shadow(color: .black.opacity(0.1), radius: 8, x: 0, y: 4)
+    }
+}
+```
+
+## Typography
+
+### San Francisco Font System
+
+Apple's system font designed for optimal legibility.
+
+```swift
+// Dynamic Type text styles
+Text("Large Title").font(.largeTitle)      // 34pt
+Text("Title").font(.title)                 // 28pt
+Text("Title 2").font(.title2)              // 22pt
+Text("Title 3").font(.title3)              // 20pt
+Text("Headline").font(.headline)           // 17pt semibold
+Text("Body").font(.body)                   // 17pt regular
+Text("Callout").font(.callout)             // 16pt
+Text("Subheadline").font(.subheadline)     // 15pt
+Text("Footnote").font(.footnote)           // 13pt
+Text("Caption").font(.caption)             // 12pt
+Text("Caption 2").font(.caption2)          // 11pt
+```
+
+### Custom Fonts with Dynamic Type
+
+```swift
+// Custom font that scales with Dynamic Type
+Text("Custom Text")
+    .font(.custom("YourFont-Regular", size: 17, relativeTo: .body))
+```
+
+### Font Weights
+
+```swift
+Text("Light").fontWeight(.light)
+Text("Regular").fontWeight(.regular)
+Text("Medium").fontWeight(.medium)
+Text("Semibold").fontWeight(.semibold)
+Text("Bold").fontWeight(.bold)
+Text("Heavy").fontWeight(.heavy)
+```
+
+### Typography Guidelines
+
+**Do:**
+- ✅ Use system font (San Francisco) for consistency
+- ✅ Support Dynamic Type for accessibility
+- ✅ Use semantic text styles (.headline, .body, etc.)
+- ✅ Minimum body text: 17pt
+- ✅ Line spacing: 120-145% of font size
+
+**Don't:**
+- ❌ Use too many font sizes (stick to system styles)
+- ❌ Make text smaller than 11pt
+- ❌ Use all caps for long text
+- ❌ Disable Dynamic Type
+
+## Colors
+
+### Semantic Colors
+
+**Colors that automatically adapt to light/dark mode.**
+
+```swift
+// UI Element Colors
+Color(.label)                    // Primary text
+Color(.secondaryLabel)           // Secondary text
+Color(.tertiaryLabel)            // Tertiary text
+Color(.quaternaryLabel)          // Watermark text
+
+Color(.systemBackground)         // Primary background
+Color(.secondarySystemBackground) // Secondary background
+Color(.tertiarySystemBackground)  // Tertiary background
+
+Color(.systemFill)               // Fill colors
+Color(.secondarySystemFill)
+Color(.tertiarySystemFill)
+Color(.quaternarySystemFill)
+
+Color(.separator)                // Separator lines
+Color(.opaqueSeparator)          // Non-transparent separator
+```
+
+### System Colors
+
+```swift
+// Standard system colors (adapt to dark mode)
+Color(.systemRed)
+Color(.systemOrange)
+Color(.systemYellow)
+Color(.systemGreen)
+Color(.systemMint)
+Color(.systemTeal)
+Color(.systemCyan)
+Color(.systemBlue)
+Color(.systemIndigo)
+Color(.systemPurple)
+Color(.systemPink)
+Color(.systemBrown)
+Color(.systemGray)
+```
+
+### Custom Colors with Dark Mode
+
+```swift
+// Define adaptive color
+extension Color {
+    static let customBackground = Color("CustomBackground")
+}
+
+// In Assets.xcassets, create color set with:
+// - Any Appearance: #FFFFFF
+// - Dark Appearance: #000000
+```
+
+### Color Contrast Guidelines
+
+**WCAG AA Compliance:**
+- Normal text: 4.5:1 contrast ratio minimum
+- Large text (24pt+): 3:1 contrast ratio minimum
+- UI components: 3:1 contrast ratio
+
+**Custom colors:**
+- Test with Increase Contrast enabled
+- Aim for 7:1 for critical text
+- Provide sufficient contrast in both modes
+
+## Spacing and Layout
+
+### 8-Point Grid System
+
+**All spacing should be multiples of 8.**
+
+```swift
+// Spacing values
+.padding(8)      // 8pt
+.padding(16)     // 16pt (standard)
+.padding(24)     // 24pt
+.padding(32)     // 32pt
+.padding(40)     // 40pt
+.padding(48)     // 48pt
+
+// Edge-specific padding
+.padding(.horizontal, 16)
+.padding(.vertical, 24)
+.padding(.top, 16)
+.padding(.bottom, 16)
+```
+
+### Safe Areas
+
+**Respect device safe areas.**
+
+```swift
+// Content within safe area (default)
+VStack {
+    Text("Content")
+}
+
+// Extend beyond safe area
+VStack {
+    Color.blue
+}
+.ignoresSafeArea()
+
+// Extend top only
+VStack {
+    Color.blue
+}
+.ignoresSafeArea(edges: .top)
+```
+
+### Touch Targets
+
+**Minimum interactive size: 44x44 points.**
+
+```swift
+Button("Tap") {
+    // Action
+}
+.frame(minWidth: 44, minHeight: 44)
+```
+
+### Spacing Guidelines
+
+```swift
+// Component spacing
+VStack(spacing: 8) {       // Tight spacing
+    Text("Line 1")
+    Text("Line 2")
+}
+
+VStack(spacing: 16) {      // Standard spacing
+    Text("Section 1")
+    Text("Section 2")
+}
+
+VStack(spacing: 24) {      // Loose spacing
+    SectionView()
+    SectionView()
+}
+```
+
+## Accessibility
+
+### VoiceOver Support
+
+**Screen reader for blind and low-vision users.**
+
+```swift
+// Accessible label
+Image(systemName: "heart.fill")
+    .accessibilityLabel("Favorite")
+
+// Accessible value
+Slider(value: $volume)
+    .accessibilityLabel("Volume")
+    .accessibilityValue("\(Int(volume * 100))%")
+
+// Accessible hint
+Button("Share") {
+    share()
+}
+.accessibilityHint("Shares this item with others")
+
+// Group elements
+HStack {
+    Image(systemName: "person")
+    Text("John Doe")
+}
+.accessibilityElement(children: .combine)
+
+// Hidden from VoiceOver
+Image("decorative")
+    .accessibilityHidden(true)
+```
+
+### Dynamic Type
+
+**Support user's preferred text size.**
+
+```swift
+// Automatically supported with system fonts
+Text("This text scales")
+    .font(.body)
+
+// Limit scaling (if necessary)
+Text("This text has limits")
+    .font(.body)
+    .dynamicTypeSize(...DynamicTypeSize.xxxLarge)
+
+// Custom font with Dynamic Type
+Text("Custom font")
+    .font(.custom("YourFont", size: 17, relativeTo: .body))
+```
+
+### Color Blindness
+
+**Design for color-blind users.**
+
+```swift
+// Don't rely on color alone
+HStack {
+    Image(systemName: "checkmark.circle.fill")
+        .foregroundColor(.green)
+    Text("Success")
+}
+
+// Not just color
+Circle()
+    .fill(.green)
+// ❌ Color only
+
+// Better with shape/icon
+HStack {
+    Image(systemName: "checkmark.circle.fill")
+    Circle().fill(.green)
+}
+// ✅ Color + shape
+```
+
+### Reduce Motion
+
+**Respect user's motion preferences.**
+
+```swift
+@Environment(\.accessibilityReduceMotion) var reduceMotion
+
+var animation: Animation {
+    reduceMotion ? .none : .spring()
+}
+
+Button("Animate") {
+    withAnimation(animation) {
+        // Animate
+    }
+}
+```
+
+### Increase Contrast
+
+**Support high contrast mode.**
+
+```swift
+@Environment(\.colorSchemeContrast) var contrast
+
+var textColor: Color {
+    contrast == .increased ? .primary : .secondary
+}
+
+Text("Content")
+    .foregroundColor(textColor)
+```
+
+## Dark Mode
+
+**Support both light and dark appearances.**
+
+### Automatic Support
+
+```swift
+// Use semantic colors (automatic)
+Color(.label)                // Adapts automatically
+Color(.systemBackground)     // Adapts automatically
+```
+
+### Testing Dark Mode
+
+```swift
+// Preview both modes
+struct ContentView_Previews: PreviewProvider {
+    static var previews: some View {
+        ContentView()
+            .preferredColorScheme(.light)
+
+        ContentView()
+            .preferredColorScheme(.dark)
+    }
+}
+```
+
+### Dark Mode Guidelines
+
+**Do:**
+- ✅ Use semantic colors
+- ✅ Test with Increase Contrast
+- ✅ Test with Reduce Transparency
+- ✅ Ensure sufficient contrast in both modes
+
+**Don't:**
+- ❌ Use pure black (#000000) - use systemBackground
+- ❌ Invert colors automatically
+- ❌ Assume user preference
+
+## SF Symbols
+
+**Apple's icon system (3000+ symbols).**
+
+```swift
+// Basic symbol
+Image(systemName: "heart")
+
+// Colored symbol
+Image(systemName: "heart.fill")
+    .foregroundColor(.red)
+
+// Sized symbol
+Image(systemName: "heart")
+    .imageScale(.large)
+
+// Font-based sizing
+Image(systemName: "heart")
+    .font(.title)
+
+// Multicolor symbols
+Image(systemName: "person.crop.circle.fill.badge.checkmark")
+    .symbolRenderingMode(.multicolor)
+
+// Hierarchical rendering
+Image(systemName: "heart.fill")
+    .symbolRenderingMode(.hierarchical)
+    .foregroundColor(.red)
+```
+
+### SF Symbols Guidelines
+
+- Use system symbols when available
+- Maintain visual weight consistency
+- Use multicolor for semantic meaning
+- Size appropriately for context
+
+## App Icons
+
+### Icon Sizes
+
+```
+iOS:
+- 1024x1024 (App Store)
+- 180x180 (iPhone @3x)
+- 120x120 (iPhone @2x)
+- 167x167 (iPad Pro)
+- 152x152 (iPad @2x)
+
+watchOS:
+- 1024x1024 (App Store)
+- 196x196 (49mm)
+- 216x216 (45mm)
+```
+
+### Icon Design Guidelines
+
+**Do:**
+- ✅ Use simple, recognizable shapes
+- ✅ Fill entire icon space
+- ✅ Test on device (not just mockups)
+- ✅ Use consistent visual style
+
+**Don't:**
+- ❌ Include text (very small)
+- ❌ Use photos
+- ❌ Replicate Apple hardware
+- ❌ Use translucency
+
+## Animation and Motion
+
+### Standard Animations
+
+```swift
+// Spring animation (natural, bouncy)
+withAnimation(.spring()) {
+    offset = 100
+}
+
+// Linear animation
+withAnimation(.linear(duration: 0.3)) {
+    opacity = 0
+}
+
+// Ease in/out
+withAnimation(.easeInOut(duration: 0.3)) {
+    scale = 1.2
+}
+```
+
+### Gesture-Driven
+
+```swift
+@State private var offset = CGSize.zero
+
+var body: some View {
+    Circle()
+        .offset(offset)
+        .gesture(
+            DragGesture()
+                .onChanged { value in
+                    offset = value.translation
+                }
+                .onEnded { _ in
+                    withAnimation(.spring()) {
+                        offset = .zero
+                    }
+                }
+        )
+}
+```
+
+### Motion Guidelines
+
+- Keep animations under 0.3 seconds
+- Use spring animations for interactive elements
+- Respect Reduce Motion setting
+- Provide visual feedback for all interactions
+
+## Best Practices
+
+### Navigation
+
+- **Hierarchical** - Use NavigationStack for drilldown
+- **Flat** - Use TabView for peer destinations
+- **Content-Driven** - Use for media apps
+
+### Feedback
+
+- **Visual** - Highlight on tap
+- **Haptic** - Use UIImpactFeedbackGenerator
+- **Audio** - Use system sounds sparingly
+
+### Loading States
+
+```swift
+struct LoadingView: View {
+    var body: some View {
+        VStack {
+            ProgressView()
+                .scaleEffect(1.5)
+            Text("Loading...")
+                .font(.caption)
+                .foregroundColor(.secondary)
+                .padding(.top)
+        }
+    }
+}
+```
+
+### Error States
+
+```swift
+struct ErrorView: View {
+    let message: String
+    let retry: () -> Void
+
+    var body: some View {
+        VStack(spacing: 16) {
+            Image(systemName: "exclamationmark.triangle")
+                .font(.system(size: 48))
+                .foregroundColor(.orange)
+
+            Text("Something went wrong")
+                .font(.headline)
+
+            Text(message)
+                .font(.subheadline)
+                .foregroundColor(.secondary)
+                .multilineTextAlignment(.center)
+
+            Button("Try Again") {
+                retry()
+            }
+            .buttonStyle(.borderedProminent)
+        }
+        .padding()
+    }
+}
+```
+
+### Empty States
+
+```swift
+struct EmptyStateView: View {
+    var body: some View {
+        VStack(spacing: 16) {
+            Image(systemName: "tray")
+                .font(.system(size: 64))
+                .foregroundColor(.secondary)
+
+            Text("No Items")
+                .font(.title2)
+
+            Text("Your items will appear here")
+                .font(.subheadline)
+                .foregroundColor(.secondary)
+
+            Button("Add Item") {
+                // Action
+            }
+            .buttonStyle(.borderedProminent)
+        }
+    }
+}
+```
+
+## Platform Considerations
+
+### iPhone
+
+- Design for various sizes (SE, Pro, Pro Max)
+- Support portrait and landscape
+- Use safe areas for notch/Dynamic Island
+- Consider one-handed use
+
+### iPad
+
+- Support multitasking (Split View, Slide Over)
+- Use sidebars for navigation
+- Adapt to larger screen (don't just scale)
+- Consider keyboard shortcuts
+- Support external displays
+
+### Apple Watch
+
+- Glanceable information
+- Large touch targets (>44pt)
+- Minimal interaction required
+- Use Digital Crown for scrolling
+- Support Always-On display

+### List
+
+Scrollable rows of content.
+
+```swift
+List {
+    Section("Today") {
+        ForEach(items) { item in
+            NavigationLink {
+                DetailView(item: item)
+            } label: {
+                HStack {
+                    Image(systemName: item.icon)

+                }
+            }
+        }
+        .onDelete { indices in
+            items.remove(atOffsets: indices)
+        }
+    }
+}
+.listStyle(.insetGrouped)
+```
+
+**List Styles:**
+- `.plain` - Edge-to-edge
+- `.insetGrouped` - Rounded sections (iOS default)

+
+### ScrollView
+
+Custom scrollable content.
+
+```swift
+ScrollView {
+    VStack(spacing: 16) {
+        ForEach(items) { item in
+            CardView(item: item)
+        }
+    }
+    .padding()
+}
+```
+
+### Grid
+
+Multi-column layout.
+
+```swift
+// LazyVGrid for vertical scrolling
+LazyVGrid(columns: [
+    GridItem(.adaptive(minimum: 150))
+]) {
+    ForEach(items) { item in
+        CardView(item: item)
+    }
+}
+
+// LazyHGrid for horizontal scrolling
+LazyHGrid(rows: [
+    GridItem(.fixed(200))
+]) {
+    ForEach(items) { item in
+        CardView(item: item)
+    }
+}
+```
+
+## Presentations
+
+### Sheet (Modal)
+
+Present content modally.
+
+```swift
+.sheet(isPresented: $showSheet) {
+    NavigationStack {
+        DetailView()
+            .navigationTitle("Details")
+            .toolbar {
+                ToolbarItem(placement: .cancellationAction) {
+                    Button("Cancel") {
+                        showSheet = false
+                    }
+                }
+            }
+    }
+    .presentationDetents([.medium, .large])
+}
+```
+
+**Detents:**
+- `.medium` - Half screen
+- `.large` - Full screen
+- Custom: `.height(400)`
+
+### Alert
+
+Important messages.
+
+```swift
+.alert("Delete Item?", isPresented: $showAlert) {
+    Button("Delete", role: .destructive) {
+        deleteItem()
+    }
+    Button("Cancel", role: .cancel) { }
+} message: {
+    Text("This action cannot be undone.")
+}
+```
+
+### Confirmation Dialog
+
+Action selection.
+
+```swift
+.confirmationDialog("Options", isPresented: $showOptions) {
+    Button("Edit") { }
+    Button("Share") { }
+    Button("Delete", role: .destructive) { }
+    Button("Cancel", role: .cancel) { }
+}
+```
+
+## Indicators
+
+### Progress View
+
+Loading indicator.
+
+```swift
+// Indeterminate
+ProgressView()
+
+// Determinate
+ProgressView(value: progress, total: 1.0)
+
+// With label
+ProgressView("Loading...") {
+    // Optional current task
+    Text("5 of 10 items")
+}
+```
+
+### Activity Indicator
+
+Spinning indicator.
+
+```swift
+ProgressView()
+    .progressViewStyle(.circular)
+    .scaleEffect(1.5)
+```
+
+## Content Containers
+
+### Card View
+
+Contained content block.
+
+```swift
+struct CardView: View {
+    var body: some View {
+        VStack(alignment: .leading, spacing: 12) {
+            Text("Title")
+                .font(.headline)
+
+            Text("Description")
+                .font(.subheadline)
+                .foregroundColor(.secondary)
+
+            Button("Action") { }
+                .buttonStyle(.borderedProminent)
+        }
+        .padding()
+        .background(Color(.systemBackground))
+        .cornerRadius(12)
+        .shadow(color: .black.opacity(0.1), radius: 8)
+    }
+}
+```
+
+### GroupBox
+
+Labeled group of views.
+
+```swift
+GroupBox("Settings") {
+    Toggle("Notifications", isOn: $notifications)
+    Toggle("Location", isOn: $location)
+}
+```
+
+### Form
+
+Settings and input grouping.
+
+```swift
+Form {
+    Section("Account") {
+        TextField("Username", text: $username)
+        SecureField("Password", text: $password)
+    }
+
+    Section("Preferences") {
+        Toggle("Notifications", isOn: $notifications)
+        Picker("Theme", selection: $theme) {
+            Text("Light").tag("light")
+            Text("Dark").tag("dark")
+        }
+    }
+}
+```
+
+## Best Practices
+
+**Navigation:**
+- Use NavigationStack for hierarchical
+- Use TabView for flat (3-5 peers)
+- Never combine TabView + Toolbar in same view
+
+**Forms:**
+- Group related inputs
+- Provide clear labels
+- Show validation errors inline
+- Use appropriate input types
+
+**Lists:**
+- Use `.insetGrouped` style
+- Support swipe actions
+- Provide pull-to-refresh when relevant
+- Use sections for organization
+
+**Modals:**
+- Use for focused tasks
+- Provide clear dismiss action
+- Don't nest modals
+- Use appropriate detent

+
+# Book Illustrator - Children's Books Specialist
+
+A comprehensive guide for creating captivating, age-appropriate children's book illustrations that tell stories, engage young minds, and bring narratives to life through visual artistry.
+
+## What This Skill Does
+
+Provides expert guidance for creating professional children's book illustrations:
+- **Age-Appropriate Design** - Tailored styles for ages 0-12
+- **Character Development** - Creating memorable, expressive characters
+- **Color Theory Mastery** - Strategic use of color for emotion and mood
+- **Visual Storytelling** - Composition and narrative through images
+- **Style Guidance** - Current trends and timeless techniques
+- **Technical Excellence** - Professional illustration standards
+- **Publishing Requirements** - Print and digital specifications
+
+## Why This Skill Matters
+
+**Without proper illustration guidance:**
+- Inconsistent character design across pages
+- Age-inappropriate complexity or simplicity
+- Poor color choices that don't support mood
+- Weak visual narrative that doesn't engage
+- Missing emotional connection with readers
+- Technical issues in printing/publishing
+
+**With expert illustration guidance:**
+- Characters that children recognize and love
+- Perfectly matched to target age group
+- Colors that enhance storytelling and emotion
+- Visual narrative that guides young readers
+- Deep emotional engagement and connection
+- Professional, publication-ready artwork
+
+## Core Principles of Children's Book Illustration
+
+### 1. Age-Appropriate Design
+
+**Understanding Your Audience:**
+- **0-2 years (Board Books):** Simple, bold, high-contrast images with clear shapes
+- **3-5 years (Picture Books):** Colorful, expressive, engaging characters with movement
+- **6-8 years (Early Readers):** More detailed scenes with visual storytelling
+- **9-12 years (Chapter Books):** Sophisticated illustrations supporting text
+
+**Design Complexity Guidelines:**
+- Toddlers need simplicity - clear lines, bright colors, recognizable objects
+- Preschoolers can handle more detail but still need visual clarity
+- Early readers benefit from illustrations that support reading development
+- Older children appreciate nuance, detail, and artistic sophistication
+
+### 2. Character Design Excellence
+
+**Creating Memorable Characters:**
+
+**Silhouette Recognition:**
+- Character should be instantly recognizable in silhouette
+- Unique shapes distinguish characters from each other
+- Strong, clear profiles that work at any size
+
+**Expression and Emotion:**
+- Eyes are the window to emotion - make them expressive
+- Body language communicates as much as facial expressions
+- Exaggerate key traits to emphasize personality
+
+**Consistency is Critical:**
+- Practice drawing your character from multiple angles
+- Create character sheets with different expressions
+- Maintain proportions and features across all pages
+- Young readers notice inconsistencies immediately
+
+**The 3-Color Rule:**
+- Limit each character to 3-4 primary colors maximum
+- Creates visual clarity and memorability
+- Makes characters easier for children to identify
+- Simplifies the illustration process
+
+**Character Design Checklist:**
+- [ ] Recognizable silhouette
+- [ ] Consistent proportions
+- [ ] Limited, strategic color palette (3-4 colors)
+- [ ] Expressive features (especially eyes)
+- [ ] Distinct personality through design
+- [ ] Age-appropriate complexity
+- [ ] Works at multiple scales
+
+### 3. Color Theory for Children's Books
+
+**Color Psychology and Emotion:**
+
+**Warm Colors:**
+- **Red:** Energy, excitement, passion (use sparingly - can overstimulate)
+- **Orange:** Playfulness, enthusiasm, warmth
+- **Yellow:** Happiness, optimism, sunlight
+
+**Cool Colors:**
+- **Blue:** Calm, trust, stability, sadness
+- **Green:** Nature, growth, harmony, safety
+- **Purple:** Magic, creativity, mystery
+
+**Color Mood Palettes:**
+
+**Happy/Playful Scene:**
+- Bright yellows, oranges, light blues
+- High saturation, warm tones
+- Clear, clean colors
+
+**Calm/Bedtime Scene:**
+- Soft pastels, muted tones
+- Lavenders, soft blues, gentle pinks
+- Low contrast, soothing palette
+
+**Adventure/Excitement:**
+- Bold primary colors
+- High contrast
+- Dynamic, energetic combinations
+
+**Mysterious/Magical:**
+- Deep purples, dark blues, sparkle accents
+- Jewel tones
+- Strategic use of light and shadow
+
+**Color Harmony Systems:**
+
+**Monochromatic:** Variations of single color
+- Use: Focused, cohesive mood
+- Example: Different shades of blue for underwater scene
+
+**Analogous:** Colors next to each other on color wheel
+- Use: Harmonious, natural feeling
+- Example: Yellow, yellow-green, green for garden scene
+
+**Complementary:** Opposite colors on wheel
+- Use: High energy, visual pop
+- Example: Blue character on orange background
+
+**Triadic:** Three colors equally spaced on wheel
+- Use: Vibrant, balanced
+- Example: Red, yellow, blue for primary fun
+
+**Strategic Background-Character Contrast:**
+- Character in warm tones? Use cool background
+- Main character in blue? Orange/yellow background pops
+- Use complementary colors for visual hierarchy
+- Guide reader's eye to important elements
+
+### 4. Visual Storytelling and Composition
+
+**The Illustration Tells the Story:**
+
+**Show, Don't Tell:**
+- Illustrations can reveal what text doesn't say
+- Character expressions show internal feelings
+- Environmental details add context and depth
+- Visual humor works alongside or beyond text
+
+**Composition Techniques:**
+
+**Rule of Thirds:**
+- Divide page into 3x3 grid
+- Place key elements at intersection points
+- Creates dynamic, interesting compositions
+
+**Leading Lines:**
+- Use paths, branches, gazes to guide the eye
+- Direct reader to important story elements
+- Create movement and flow
+
+**Visual Hierarchy:**
+- Most important element = largest, highest contrast
+- Secondary elements support but don't compete
+- Background provides context without distraction
+
+**Perspective and Point of View:**
+
+**Eye-Level:** Neutral, relatable

+# Character Design for Children's Books
+
+## The Foundation of Great Character Design
+
+Children's book characters become lifelong friends. They must be:
+- **Instantly recognizable** - Clear, memorable silhouettes
+- **Emotionally expressive** - Feelings are obvious
+- **Consistent** - Look the same on every page
+- **Age-appropriate** - Match target reader developmental stage
+- **Visually appealing** - Attractive to young eyes
+
+## The Silhouette Test
+
+### What Is It?
+Fill your character with solid black. Can you still tell who/what it is?
+
+### Why It Matters
+- Children identify characters by overall shape first
+- Strong silhouettes work at any size
+- Distinctive shapes create memorability
+- Good silhouettes reproduce well in any medium
+
+### Creating Strong Silhouettes
+
+**Add Distinctive Elements:**
+- Unique head shape
+- Characteristic ears, hair, or hat
+- Distinctive body proportion
+- Signature tail, accessory, or clothing
+- Unusual posture or stance
+
+**Examples:**
+- **Rabbit:** Tall ears, round body, puff tail
+- **Bear:** Round ears, broad shoulders, sturdy build
+- **Bird:** Crest or beak shape, wing position, tail feathers
+- **Human Child:** Hair shape, clothing silhouette, body proportion
+
+**Test Your Silhouette:**
+1. Fill character with solid color
+2. View at thumbnail size
+3. Is it recognizable?
+4. Is it different from other characters?
+5. Does it communicate personality?
+
+## The 3-4 Color Rule for Characters
+
+### Why Limit Colors?
+- **Recognition:** Easier for children to identify
+- **Consistency:** Simpler to maintain across pages
+- **Visual Clarity:** Not overwhelming
+- **Practical:** Easier to draw repeatedly
+
+### How to Choose Your 3-4 Colors
+
+**1. Primary Color (Dominant)**
+- Covers largest area
+- Defines character at a glance
+- Often fur, skin, or main clothing
+
+**2. Secondary Color (Supporting)**
+- Second-largest area
+- Complements or contrasts primary
+- Often secondary clothing, markings, accessories
+
+**3. Accent Color (Pop)**
+- Small areas for visual interest
+- Often eyes, nose, small accessories
+- Usually contrasts with primary
+
+**4. Detail Color (Optional)**
+- Smallest elements
+- Eyes, patterns, tiny details
+- Often black, white, or saturated accent
+
+### Character Color Examples
+
+**Example 1: Fox Character**
+- Primary: Orange fur (main body)
+- Secondary: White chest and tail tip
+- Accent: Green scarf
+- Detail: Black nose, eyes, paw pads
+
+**Example 2: Child Character**
+- Primary: Brown skin
+- Secondary: Blue overalls
+- Accent: Yellow shirt
+- Detail: Black hair, white eyes
+
+**Example 3: Monster Character**
+- Primary: Purple body
+- Secondary: Green spots
+- Accent: Orange horns
+- Detail: Black eyes, white teeth

+
+**Hybrid Approach:**
+- Animal head on human-like body
+- Human clothes on animal frame
+- Mix of human and animal features
+- Consistent rules throughout book
+
+## Character Design Mistakes to Avoid
+
+### ❌ Too Complex
+**Problem:** Hard to draw consistently, busy appearance
+**Solution:** Simplify, focus on key features, remember you'll draw this 30+ times
+
+### ❌ Too Generic
+**Problem:** Forgettable, looks like many others
+**Solution:** Add distinctive element, unique shape language, signature feature
+
+### ❌ Doesn't Match Story
+**Problem:** Visual personality contradicts character role
+**Solution:** Align shape, color, style with character's nature
+
+### ❌ Not Age-Appropriate
+**Problem:** Too scary for young kids, too babyish for older
+**Solution:** Research target age, study successful examples
+
+### ❌ Inconsistent Details
+**Problem:** Stripes change, accessories vary, proportions shift
+**Solution:** Detailed character sheet, reference constantly
+
+### ❌ Poor Silhouette
+**Problem:** Blob shape, not distinctive
+**Solution:** Silhouette test, add unique elements
+
+### ❌ Stereotypical Representation
+**Problem:** Offensive or clichéd diverse characters
+**Solution:** Research, sensitivity readers, authentic details
+

+- Bright blues and greens can shift
+- Always request color proofs
+- Some RGB colors can't be reproduced
+
+**Tips:**
+- Work in CMYK mode from start if printing
+- Test palette in intended medium
+- Understand ink limitations
+- Request printed proofs
+
+### Digital (RGB)
+**What:** Red, Green, Blue light mixing
+**Considerations:**
+- Brighter, more saturated than print
+- Screen variation affects appearance
+- File size considerations
+
+**Tips:**
+- Optimize for file size
+- Test on multiple devices
+- Use standard color profiles
+- Consider e-reader limitations
+
+### Color Accessibility
+
+**Color Blindness Considerations:**
+
+**Red-Green Color Blindness (Most Common):**
+- Don't rely on red vs. green alone
+- Add pattern, texture, or value contrast
+- Test with color blindness simulators
+
+**Blue-Yellow Color Blindness:**
+- Less common but important
+- Ensure sufficient value contrast
+
+**Full Color Blindness:**
+- Ensure illustrations work in grayscale
+- Use value and contrast effectively
+
+**Tools:**
+- Color Oracle (free simulator)

+
+## Character Color Assignment
+
+### The 3-4 Color Rule
+**Principle:** Limit each character to 3-4 main colors
+
+**Example - Bear Character:**
+1. **Primary:** Brown fur
+2. **Secondary:** Cream belly/muzzle
+3. **Accent:** Red shirt
+4. **Detail:** Black nose/eyes

+
+**Cool Character on Warm Background:**
+- Blue elephant on orange sunset
+- Purple character in golden field
+- Teal fish in coral reef
+
+**Value Contrast:**
+- Light character on dark background (or vice versa)
+- Ensures readability
+- Creates focus
+
+## Color Consistency Tips
+
+### Create a Color Palette Document
+**Include:**
+- Exact color values (RGB or CMYK)
+- Color swatches
+- Character assignments
+- Scene mood notes
+
+### Use Color Scripts
+**What:** Small thumbnail of each spread showing only color
+**Purpose:**
+- See color flow through entire book
+- Ensure variety and consistency
+- Check pacing and mood progression
+
+### Digital Color Management
+**Tools:**
+- Procreate: Create custom color palettes
+- Photoshop: Swatches and color libraries
+- Clip Studio: Material palettes
+- Adobe Color: Generate harmonies online
+
+### Test Prints
+- Print small color tests regularly
+- Check under different lighting
+- Verify consistency across spreads
+- Adjust for production method
+
+## Common Color Mistakes
+
+### ❌ Too Many Colors
+**Problem:** Visual chaos, no cohesion
+**Solution:** Limit palette, create color harmony system
+
+### ❌ Muddy Colors
+**Problem:** Over-mixing, dirty appearance
+**Solution:** Keep colors pure, use clean mixes, avoid too many complements
+
+### ❌ No Contrast
+**Problem:** Everything blends together
+**Solution:** Ensure value contrast, use complementary colors strategically
+
+### ❌ Ignoring Color Temperature
+**Problem:** Palette feels off or conflicting
+**Solution:** Choose warm or cool dominance, use temperature for depth
+
+### ❌ Same Intensity Throughout
+**Problem:** Visually exhausting, no rest areas
+**Solution:** Vary saturation, include neutral areas
+
+### ❌ Not Testing for Print
+**Problem:** Colors look different when printed
+**Solution:** Work in CMYK, get color proofs, test prints
+

+# Composition Techniques for Children's Book Illustration
+
+## What is Composition?
+
+Composition is how you arrange elements within your illustration to:
+- Guide the viewer's eye
+- Tell the story visually
+- Create mood and emotion
+- Establish hierarchy and focus
+- Balance and organize visual elements
+
+Good composition in children's books is ESSENTIAL because young readers' eyes need clear guidance to follow the narrative.
+
+## The Rule of Thirds
+
+### What Is It?
+Divide your page into a 3x3 grid (like a tic-tac-toe board). Place important elements at the intersection points or along the lines.
+
+### Why It Works
+- Creates natural visual interest
+- Avoids static, centered compositions
+- Guides eye movement
+- Feels balanced but dynamic
+
+### How to Use It
+
+**Power Points (Intersections):**
+- Place main character's face or eyes here
+- Position key action at these spots
+- Put important story elements at intersections
+
+**The Lines:**
+- Horizon along top or bottom third
+- Characters along vertical thirds
+- Key elements aligned with lines
+
+**Example:**
+- Character's eyes at top-right intersection
+- Body along right vertical line
+- Ground/floor along bottom horizontal line
+
+### When to Break It
+- Centered compositions for calm, symmetrical moments
+- Full-page spreads for impact
+- Intentional symmetry for special effects
+
+## Visual Hierarchy
+
+### What Is It?
+The order in which the eye notices elements, from most to least important.
+
+### Creating Hierarchy
+
+**1. Size**
+- Larger = more important
+- Main character usually largest
+- Background elements smaller
+
+**2. Contrast**
+- High contrast = attention
+- Main elements have strongest contrast
+- Background has lower contrast
+
+**3. Color**
+- Bright, saturated = eye-catching
+- Main character in boldest colors
+- Background more muted
+
+**4. Detail**
+- More detail = more focus
+- Main elements most detailed
+- Background simplified
+
+**5. Position**
+- Center or intersection points = important
+- Foreground = primary focus
+- Background = context
+
+**6. Isolation**
+- Surrounded by space = important
+- Use negative space strategically
+- Isolation creates emphasis
+
+### Hierarchy in Children's Books
+
+**Clear Focus:**
+- ONE main focal point per page/spread
+- Supporting elements don't compete
+- Background supports, doesn't distract
+
+**Age Considerations:**
+- Younger readers need VERY clear hierarchy
+- Older readers can handle more complexity
+- When in doubt, simplify
+
+## The Golden Ratio and Dynamic Symmetry
+
+### The Golden Ratio (Phi - 1.618)
+A mathematical ratio found in nature that creates pleasing compositions.
+
+**Practical Use:**
+- Similar to rule of thirds but more refined
+- Place horizon at golden ratio line
+- Size relationships using 1:1.618
+- Creates natural, harmonious feel
+
+**Golden Spiral:**
+- Fibonacci spiral
+- Arrange elements along curve
+- Eye follows natural path
+- Found in nature (shells, flowers)
+
+### When to Use
+- More sophisticated illustrations (ages 8+)
+- Nature scenes
+- Creating flow and movement
+- Sophisticated layouts
+
+## Leading Lines
+
+### What Are They?
+Lines within your composition that guide the viewer's eye toward the focal point.
+
+### Types of Leading Lines
+
+**Physical Lines:**
+- Roads, paths, rivers
+- Branches, vines, ropes
+- Fences, walls, bridges
+- Cracks, trails, shadows
+
+**Implied Lines:**
+- Character's gaze direction
+- Pointing gestures
+- Line of motion
+- Alignment of objects
+
+### How to Use Leading Lines
+
+**Converging Lines:**
+- Multiple lines pointing to focal point
+- Creates depth and perspective
+- Draws eye to main character or action
+
+**Curved Lines:**
+- S-curves create graceful movement
+- C-curves embrace and enfold
+- Spirals create dynamic energy
+
+**Diagonal Lines:**
+- Create energy and movement
+- More dynamic than horizontal/vertical
+- Guide eye across page
+
+**Example:**
+- Path curves from bottom-left to character at right intersection
+- Tree branches point toward character's face
+- Character's gaze leads to next story element
+
+## Depth and Layers
+
+### The Three Planes
+
+**Foreground:**
+- Closest to viewer
+- Largest, most detailed
+- Can frame the scene
+- Sometimes partially cropped
+
+**Middle Ground:**
+- Where main action usually happens
+- Characters and key elements
+- Focal point often here
+- Medium detail
+
+**Background:**
+- Furthest from viewer
+- Smallest elements
+- Sets scene and mood
+- Simplified detail
+
+### Creating Depth
+
+**Overlapping:**
+- Elements in front partially hide those behind
+- Immediate depth perception
+- Clear spatial relationships
+
+**Size Variation:**
+- Larger = closer
+- Smaller = farther
+- Follow realistic scaling
+
+**Detail Gradation:**
+- Foreground: Most detail
+- Middle ground: Medium detail
+- Background: Simplified shapes
+
+**Color and Value:**
+- Atmospheric perspective
+- Distant objects lighter, less saturated
+- Foreground more saturated, darker darks
+
+**Sharpness:**
+- Foreground sharp and clear
+- Background softer, less defined
+- Creates focus and depth
+
+## Page Layout Strategies
+
+### Single Page Illustrations
+
+**Full Bleed:**
+- Image extends to edge
+- Immersive, dramatic
+- No white space frame
+- Use for: Action, immersion, key moments
+
+**Vignette:**
+- Image fades into white background
+- Floats on page
+- Intimate, focused feeling
+- Use for: Quiet moments, character focus, classic feel
+
+**Spot Illustration:**
+- Smaller image with text around it
+- Multiple per page possible
+- Breaks up text in early readers
+- Use for: Chapter books, text-heavy pages
+
+### Spread Compositions (Two-Page)
+
+**Across the Gutter:**
+- Image spans both pages
+- Creates expansive feeling
+- IMPORTANT: Avoid critical elements in gutter (center binding)
+- Use for: Large scenes, panoramas, impact
+
+**Divided Spread:**
+- Different content on each page
+- Left sets up, right delivers
+- Can show before/after, cause/effect
+- Use for: Pacing, storytelling beats
+
+**Asymmetrical Spread:**
+- Most action on one page
+- Other page supports or provides breathing room
+- Creates dynamic energy
+- Use for: Varied pacing, visual interest
+
+## Perspective and Point of View
+
+### Eye Level (Neutral)
+**What:** Camera at character's eye level
+**Effect:** Neutral, relatable, conversational
+**Use for:** Normal interactions, dialogue, everyday moments
+**Emotion:** Comfortable, equal, friendly
+
+### Bird's Eye View (High Angle)
+**What:** Looking down from above
+**Effect:** Shows layout, makes character seem small
+**Use for:** Showing full scene, character feeling overwhelmed/small
+**Emotion:** Vulnerable, lost, surveying, planning
+
+### Worm's Eye View (Low Angle)
+**What:** Looking up from below
+**Effect:** Makes character seem large, powerful, imposing
+**Use for:** Brave moments, imposing figures, victory
+**Emotion:** Powerful, intimidating, triumphant, awe
+
+### Dutch Angle (Tilted)
+**What:** Horizon line tilted
+**Effect:** Unease, energy, chaos
+**Use for:** Confusion, excitement, things going wrong
+**Emotion:** Disoriented, dynamic, unstable
+
+### Forced Perspective
+**What:** Exaggerated perspective for dramatic effect
+**Effect:** Dynamic, energetic, surprising
+**Use for:** Action, emphasis, visual excitement
+**Emotion:** Dramatic, intense, surprising
+
+## Balance and Symmetry
+
+### Symmetrical Balance
+**What:** Mirror image on both sides
+**Effect:** Calm, stable, formal, peaceful
+**Use for:** Calm moments, formal scenes, stability
+**Examples:** Character centered, same elements both sides
+
+### Asymmetrical Balance
+**What:** Different elements that balance visually
+**Effect:** Dynamic, interesting, natural
+**Use for:** Most scenes, visual interest
+**Examples:** Large element left, multiple small elements right
+
+### Radial Balance
+**What:** Elements radiate from center point
+**Effect:** Energy, focus, movement
+**Use for:** Explosions of joy, surprise, energy
+**Examples:** Fireworks, flowers, excitement bursts
+
+## Creating Movement and Flow
+
+### Directional Movement
+
+**Left to Right:**
+- Follows Western reading direction
+- Feels natural, forward-moving
+- Progressive, advancing
+
+**Right to Left:**
+- Against reading direction
+- Can feel like going back or resistance
+- Use intentionally
+
+**Diagonal:**
+- Most dynamic
+- Upward diagonal = rising, positive
+- Downward diagonal = falling, negative
+
+**Circular:**
+- Continuous, cyclical
+- Eye keeps moving
+- Energetic, flowing
+
+### Guiding the Eye
+
+**Primary Path:**
+1. Eye enters composition (usually top-left in Western books)
+2. Travels to focal point (main character or action)
+3. Explores supporting elements
+4. Exits (often bottom-right, ready for page turn)
+
+**Creating the Path:**
+- Use leading lines
+- Employ character gaze
+- Strategic color placement
+- Size and contrast cues
+
+## Framing Techniques
+
+### Natural Frames
+**What:** Using elements in scene to frame main subject
+
+**Examples:**
+- Tree branches forming arch
+- Doorway or window
+- Foliage on sides
+- Rock formations
+
+**Effect:**
+- Draws eye to subject
+- Creates depth
+- Adds context
+- Focuses attention
+
+### Negative Space Framing
+**What:** Empty space around subject
+**Effect:** Emphasis, breathing room, elegance
+**Use for:** Important moments, emotional beats, clarity
+
+## Composition for Storytelling
+
+### Beginning
+**Composition Approach:**
+- Establish setting with wide view
+- Introduce character in context
+- Calm, clear compositions
+- Lots of context and environment
+
+### Middle (Conflict/Action)
+**Composition Approach:**
+- Dynamic angles
+- Closer crops
+- More movement
+- Varied perspectives
+- Tension through composition
+
+### End (Resolution)
+**Composition Approach:**
+- Return to calm
+- Wide views showing resolution
+- Balanced, peaceful compositions
+- Satisfying visual closure
+
+## The Page Turn
+
+### Creating Anticipation
+
+**Left Page (Recto):**
+- Set up question or problem
+- Show character noticing something
+- Tension building
+- Gaze or movement toward gutter/turn
+
+**Right Page (Verso):**
+- Answer or surprise
+- What character sees/finds
+- Resolution or escalation
+- Payoff for the turn
+
+### Examples
+
+**Setup → Reveal:**
+- Left: Character looking up at something off-page
+- Right: What they see (big reveal)
+
+**Problem → Solution:**
+- Left: Character facing challenge
+- Right: Character solving it
+
+**Before → After:**
+- Left: Messy room
+- Right: Clean room
+
+## Age-Appropriate Composition
+
+### Ages 0-2 (Board Books)
+**Keep It Simple:**
+- One main element per page
+- Centered or very simple composition
+- High contrast
+- Minimal background
+- No complex layers
+
+### Ages 3-5 (Picture Books)
+**Clear Focus:**
+- One clear focal point
+- Simple foreground/background
+- Easy-to-follow flow
+- Playful but clear
+- Some depth okay
+
+### Ages 6-8 (Early Readers)
+**More Complex:**
+- Multiple elements okay
+- Can use layers effectively
+- More sophisticated perspective
+- Visual subplots in background
+- Varied angles
+
+### Ages 9-12 (Chapter Books)
+**Sophisticated:**
+- Complex compositions fine
+- Multiple focal points
+- Sophisticated perspective
+- Rich detail and layers
+- Cinematic approaches
+
+## Creating Mood Through Composition
+
+### Happy/Joyful
+- Open, airy compositions
+- Lots of sky/space
+- Symmetrical or balanced
+- Bright, clear focal points
+- Upward movement
+
+### Sad/Melancholy
+- Heavier bottom, lighter top
+- Character small in frame
+- Lots of empty space
+- Downward movement
+- Muted, gentle flow
+
+### Scary/Tense
+- Dark areas, limited light
+- Asymmetrical, unbalanced
+- Tilted angles
+- Tight crops
+- Shadows and mystery
+
+### Exciting/Energetic
+- Dynamic diagonals
+- Action-oriented
+- Close crops
+- Varied perspectives
+- Movement and flow
+
+### Calm/Peaceful
+- Horizontal lines
+- Symmetrical balance
+- Lots of breathing room
+- Gentle curves
+- Restful composition
+
+## Text Placement Considerations
+
+### Working With Text
+
+**Clear Text Areas:**
+- Leave calm, simple areas for text
+- Usually top, bottom, or sides
+- Not over important illustration elements
+- Check with designer/layout artist
+
+**Text Flow:**
+- Don't force awkward text placement
+- Consider reading order
+- Leave appropriate white space
+- Background should support, not fight text
+
+**Common Text Zones:**
+- Top third for title/opening
+- Bottom for descriptive text
+- Sides for margin text
+- Sky areas for minimal interference
+
+### Illustrations That Support Text
+
+**Visual Breathing Room:**
+- Calm sky for text
+- Simplified background areas
+- Strategic negative space
+- Planned text zones
+
+**Don't Compete:**
+- Busy illustration + text = hard to read
+- Important details under text = frustration
+- Plan together with text in mind
+
+## Common Composition Mistakes
+
+### ❌ Bullseye (Everything Centered)
+**Problem:** Static, boring, no movement
+**Solution:** Use rule of thirds, asymmetry, dynamic placement
+
+### ❌ Tangents (Awkward Overlaps)
+**Problem:** Lines or edges that touch confusingly
+**Solution:** Clear overlaps or clear separation, avoid exact tangents
+
+### ❌ Competing Focal Points
+**Problem:** Multiple elements fighting for attention
+**Solution:** Clear hierarchy, one main focus, supporting elements
+
+### ❌ Ignoring the Gutter
+**Problem:** Important elements lost in binding
+**Solution:** 0.5" safe zone from center, plan for gutter
+
+### ❌ No Clear Entry Point
+**Problem:** Eye doesn't know where to start
+**Solution:** Clear focal point, leading lines, hierarchy
+
+### ❌ Too Much Negative Space
+**Problem:** Feels empty, incomplete
+**Solution:** Fill appropriately for mood, age group
+
+### ❌ Too Busy/Cluttered
+**Problem:** Overwhelming, confusing, exhausting
+**Solution:** Simplify, clear focus, strategic detail
+
+### ❌ Awkward Cropping
+**Problem:** Cutting through joints, odd crops
+**Solution:** Crop thoughtfully, avoid joints (knees, elbows), or show entirely
+
+## Composition Checklist
+
+**Before You Sketch:**
+- [ ] Identify focal point (what's most important?)
+- [ ] Consider page turn (setup or payoff?)
+- [ ] Think about text placement
+- [ ] Choose appropriate perspective
+- [ ] Plan mood and emotion
+
+**While Composing:**
+- [ ] Apply rule of thirds or golden ratio
+- [ ] Create clear visual hierarchy
+- [ ] Use leading lines to focal point
+- [ ] Establish foreground/middle/background
+- [ ] Check for tangents and awkward overlaps
+- [ ] Ensure clear entry and exit for eye
+- [ ] Balance composition appropriately
+- [ ] Consider gutter if spread
+
+**Before Finalizing:**
+- [ ] Test at thumbnail size (still clear?)
+- [ ] Check that focal point is obvious
+- [ ] Verify age-appropriateness
+- [ ] Ensure text areas are clear
+- [ ] Confirm mood matches story moment
+- [ ] Look for unintended tangents
+- [ ] Test spread as a whole (if applicable)
+- [ ] Check visual flow through book
+
+## Advanced Techniques
+
+### Atmospheric Perspective
+- Distant objects lighter, less saturated, less detailed
+- Creates depth and atmosphere
+- Especially effective for landscapes
+
+### Overlapping Shapes
+- Creates instant depth
+- Shows spatial relationships
+- Guides eye through layers
+
+### Color Temperature Depth
+- Warm colors advance (come forward)
+- Cool colors recede (go back)
+- Use for depth without value change
+
+### Size and Scale Surprises
+- Unexpected scale creates drama
+- Tiny character in huge space
+- Giant close-up detail
+- Forces perspective on viewer
+
+### Breaking the Frame
+- Element extends beyond edge
+- Creates energy
+- Implies larger world
+- Engages viewer
+
+## Composition Exercise Ideas
+
+### Practice Activities
+
+**1. Thumbnail Variations:**
+- Same scene, 10 different compositions
+- Try different angles, crops, perspectives
+- Identify strongest option
+
+**2. Rule of Thirds Practice:**
+- Draw grid on existing illustrations
+- Analyze professional books
+- See where focal points fall
+
+**3. Silhouette Composition:**
+- Create composition in solid black shapes
+- Does it still read clearly?
+- Tests strength of layout
+
+**4. Color Block Composition:**
+- Fill composition with flat color areas
+- No detail, just composition and color
+- Reveals structure
+
+**5. Reverse Engineering:**
+- Analyze favorite books
+- Identify composition techniques
+- Understand why they work
+
+## Summary
+
+Strong composition in children's book illustration:
+
+✅ **Guides young readers' eyes** clearly and intentionally
+✅ **Supports the story** through visual structure
+✅ **Creates appropriate mood** for each moment
+✅ **Balances visual interest** with clarity
+✅ **Considers the reader's experience** from entry to exit
+✅ **Works with text** not against it
+✅ **Age-appropriate** in complexity
+✅ **Enhances narrative** through thoughtful arrangement
+
+**Remember:** Composition is invisible when done well—readers don't notice it, they just enjoy a clear, engaging, emotionally resonant visual experience. Your job is to guide them through the story with intention, clarity, and artistry.
+
+**Final Tip:** When in doubt, simplify. Children's books need clarity above all. A simple, clear composition always beats a complex, confusing one.

+## Common Content Brief Mistakes
+
+### ❌ Avoid These
+
+**Too Vague:**
+"Write about our product"
+→ No clear audience, goal, or angle
+
+**No Research:**
+Missing competitor analysis and keyword research
+→ Content won't rank or differentiate
+
+**Unclear Voice:**
+"Make it engaging"
+→ Not specific enough for consistency
+
+**Missing CTAs:**
+No clear next step for readers
+→ Missed conversion opportunities
+
+**Ignoring SEO:**
+No keyword strategy
+→ Content won't be discovered
+
+### ✅ Do This Instead
+
+**Specific:**
+"Write 1500-word tutorial for junior developers on JWT authentication, including code examples in Node.js"
+
+**Research-Backed:**
+"Target keyword 'JWT authentication tutorial' (2.4K monthly searches), compete with existing articles from Auth0 and FreeCodeCamp"
+
+**Clear Voice:**
+"Technical but approachable - explain like a senior dev mentoring a junior, use examples, avoid jargon"
+
+**Action-Oriented:**
+"CTA: Sign up for free API key, secondary: Join Discord community"
+
+**SEO-Optimized:**
+"Primary: 'JWT authentication', Secondary: 'JSON web token Node.js', 'secure API authentication'"

+
+---
+
+## Keyword Strategy
+
+### Primary Keyword
+**One main target keyword per piece of content**
+
+**Characteristics:**
+- Relevant to topic
+- Moderate search volume (500-10K typically)
+- Achievable difficulty
+- Matches search intent
+
+**Example:**
+For a tutorial on JWT authentication:

+## What Is JWT Authentication?
+
+JWT (JSON Web Token) authentication is a stateless authentication method that uses cryptographically signed tokens to verify user identity. Instead of storing session data on the server, JWT embeds user information in a secure token that clients include with each request.
+
+### How JWT Authentication Works:
+
+1. User logs in with credentials
+2. Server validates and creates JWT
+3. Token sent to client
+4. Client includes token in requests
+5. Server verifies token signature
+```

+
+## Developing Your Voice
+
+### Step 1: Define Core Attributes
+
+Choose 3-4 from these dimensions:
+
+**Formality:**
+- Formal, professional, casual, conversational
+
+**Humor:**
+- Serious, playful, witty, irreverent
+
+**Enthusiasm:**
+- Energetic, neutral, understated
+
+**Technical:**
+- Expert, accessible, simple
+
+**Empathy:**
+- Warm, neutral, distant
+
+---
+
+### Step 2: Create Voice Chart
+
+| Attribute | We are | We are not | Example |
+|-----------|---------|------------|---------|
+| Professional | Clear and helpful | Stuffy or robotic | "Here's how to..." not "One must..." |
+| Friendly | Warm and welcoming | Overly casual | "Welcome!" not "Sup!" |
+| Technical | Accurate and precise | Jargon-heavy | Explain terms first time |
+
+---
+
+### Step 3: Write Examples
+
+For each voice attribute, write before/after examples:
+
+**Before (generic):**
+"Our platform provides solutions for your business needs."
+
+**After (our voice - direct, technical, helpful):**
+"Deploy your apps faster with built-in CI/CD and automatic scaling."
+
+---
+
+### Step 4: Create Voice Guidelines
+
+Document:
+- [ ] Core voice attributes (3-4)
+- [ ] Do's and don'ts
+- [ ] Example sentences
+- [ ] Tone by context
+- [ ] Word choice preferences
+- [ ] Grammar rules (contractions, etc.)
+
+---
+
+## Testing Your Voice
+
+### Voice Consistency Check
+
+1. **Remove branding** from 5 pieces of content
+2. **Mix with competitors'** content
+3. **Can people identify yours?**
+
+If yes → Voice is distinctive
+If no → Need stronger voice
+
+---
+
+### Reader Feedback
+
+Ask your audience:
+- How would you describe our voice?
+- Does it match your expectations?
+- What do you like/dislike?
+
+---
+
+## Maintaining Voice
+
+### Team Alignment
+
+**Onboarding:**
+- Share voice guidelines
+- Review examples
+- Practice exercises
+
+**Review Process:**
+- Check content against voice guidelines
+- Provide specific feedback
+- Create a voice champion
+
+**Documentation:**
+- Voice guidelines in shared doc
+- Examples library
+- Regular updates
+
+---
+
+### Voice Evolution
+
+**When to evolve:**
+- Rebranding
+- New audience
+- Company maturity
+- Market shift
+
+**How to evolve:**
+- Document changes
+- Transition gradually
+- Update guidelines
+- Train team
+
+**What to keep:**
+- Core personality
+- Brand values
+- Recognition
+
+---

+name: design-brief-generator
+description: Generate comprehensive design briefs for design projects. Use this skill when designers ask to "create a design brief", "structure a design project", "define design requirements", or need help planning design work.
+---
+
+# Design Brief Generator
+
+## Overview
+
+Generate comprehensive, well-structured design briefs that align stakeholders and guide design projects. This skill helps designers create clear project briefs that define scope, goals, constraints, and success criteria.
+
+**Built for:**
+- UX/UI designers
+- Product designers
+- Design leads
+- Design systems teams
+- Brand designers
+
+---
+
+## Quick Start
+
+### 1. Generate Design Brief
+
+Run the interactive script:
+
+```bash
+scripts/generate_brief.sh
+```
+
+This will guide you through creating a comprehensive design brief covering:
+- Project goals and objectives
+- Target users and personas
+- Design constraints
+- Success criteria
+- Timeline and deliverables
+
+### 2. Validate Brief
+
+Check brief completeness:
+
+```bash
+scripts/validate_brief.sh <brief_file.md>
+```
+
+Ensures all critical sections are included.
+
+---
+
+## Core Workflow
+
+### When to Create a Design Brief
+
+**Use a design brief for:**
+- New product/feature design projects
+- Design system initiatives
+- Redesign projects
+- Brand identity projects
+- UX research initiatives
+
+**Skip for:**
+- Minor UI tweaks
+- Bug fixes
+- Small iterations on existing designs
+
+---
+
+## Design Brief Components
+
+### 1. Project Overview
+
+**What it includes:**
+- Project name and description
+- Background and context
+- Why this project matters now
+- Business objectives
+- User problems being solved
+
+**Example:**
+```markdown
+## Project Overview
+
+**Project:** Mobile app redesign
+**Background:** Current app has 2.8 star rating with users citing confusing navigation
+**Business Goal:** Increase app retention from 15% to 40% (Day 30)
+**User Problem:** Users can't find key features, leading to frustration and abandonment
+```
+
+---
+
+### 2. Design Goals & Objectives
+
+**Define what success looks like:**
+- Primary design goal
+- Secondary goals
+- Success metrics
+- Must-haves vs. nice-to-haves
+
+**Example:**
+```markdown
+## Design Goals
+
+**Primary Goal:** Create intuitive navigation that helps users complete core tasks in < 3 taps
+
+**Secondary Goals:**
+- Reduce visual clutter by 40%
+- Improve accessibility (WCAG AA compliance)
+- Establish reusable component library
+
+**Success Metrics:**
+- Task success rate: 90%+
+- Time on task: -50%
+- SUS score: 75+
+```
+
+---
+
+### 3. Target Users & Personas
+
+**Who are we designing for:**
+- Primary user personas
+- User needs and pain points
+- User goals and motivations
+- Technical proficiency
+- Context of use
+
+**Example:**
+```markdown
+## Target Users
+
+**Primary Persona:** Sarah, Marketing Manager
+- **Age:** 32-45
+- **Tech Savvy:** Medium
+- **Goals:** Create campaigns quickly, track performance
+- **Pain Points:** Current tool too complex, takes too long
+- **Context:** Uses on desktop during work hours, sometimes mobile
+```
+
+---
+
+### 4. Design Principles & Direction
+
+**Guiding principles for the project:**
+- Core design principles
+- Visual direction
+- Interaction patterns
+- Content strategy
+- Accessibility requirements
+
+**Example:**
+```markdown
+## Design Principles
+
+1. **Clarity over cleverness** - Users should never wonder what to do next
+2. **Progressive disclosure** - Show what's needed, hide complexity
+3. **Consistent patterns** - Use established design system components
+4. **Accessible by default** - WCAG AA minimum, aim for AAA
+```
+
+---
+
+### 5. Scope & Constraints
+
+**What's in and out of scope:**
+
+**In Scope:**
+- Screens/flows included
+- Platforms (web, mobile, tablet)
+- Devices and browsers
+- Accessibility requirements
+
+**Out of Scope:**
+- What we're NOT designing
+- Future considerations
+
+**Constraints:**
+- Technical limitations
+- Timeline constraints
+- Resource constraints
+- Brand guidelines to follow
+
+**Example:**
+```markdown
+## Scope
+
+**In Scope:**
+- Dashboard redesign (5 screens)
+- Mobile responsive (iOS, Android)
+- Dark mode support
+- WCAG AA compliance
+
+**Out of Scope:**
+- Admin panel (separate project)
+- Native mobile apps (web only)
+- Marketing website
+
+**Constraints:**
+- Must use existing design system
+- Launch deadline: 8 weeks
+- Development team: 2 engineers
+- No custom illustrations budget
+```
+
+---
+
+### 6. User Flows & Journeys
+
+**Key user paths to design:**
+- Primary user flows
+- Entry points
+- Decision points
+- Success states
+- Error states
+
+**Example:**
+```markdown
+## Key User Flows
+
+**Flow 1: Create Campaign**
+1. Land on dashboard
+2. Click "New Campaign"
+3. Choose template
+4. Customize content
+5. Preview
+6. Publish
+7. Success confirmation
+
+**Flow 2: View Analytics**
+[Define the flow]
+```
+
+---
+
+### 7. Deliverables & Timeline
+
+**What will be delivered:**
+
+**Design Deliverables:**
+- User research (if needed)
+- Wireframes
+- High-fidelity mockups
+- Interactive prototype
+- Design specifications
+- Component documentation
+- Accessibility annotations
+
+**Timeline:**
+- Week 1-2: Research & wireframes
+- Week 3-4: High-fidelity designs
+- Week 5-6: Prototype & testing
+- Week 7-8: Refinement & handoff
+
+---
+
+### 8. Success Criteria
+
+**How we'll measure success:**
+
+**Qualitative:**
+- User testing feedback
+- Stakeholder approval
+- Designer review
+- Accessibility audit pass
+
+**Quantitative:**
+- Task success rate
+- Time on task
+- Error rate
+- SUS score
+- NPS
+
+**Example:**
+```markdown
+## Success Criteria
+
+**Usability Testing:**
+- 8/10 users complete primary task without help
+- Average SUS score: 75+
+- Zero critical accessibility issues
+
+**Business Metrics (post-launch):**
+- 40% Day 30 retention (up from 15%)
+- 90% task completion rate
+- < 5% error rate
+```
+
+---
+

+## Stakeholder Alignment
+
+### Discovery Questions
+
+**Ask before starting:**
+1. What problem are we solving?
+2. Who are the users?
+3. What are the business goals?
+4. What's the timeline?
+5. What are the constraints?
+6. How will we measure success?
+7. Who needs to approve?
+
+### Stakeholder Review Process
+
+**Brief review checklist:**
+- [ ] Product Manager reviewed
+- [ ] Engineering lead reviewed (feasibility)
+- [ ] Design lead approved
+- [ ] Key stakeholders aligned
+- [ ] Success metrics agreed upon
+- [ ] Timeline confirmed
+- [ ] Resources allocated
+
+---
+
+## Design Brief Best Practices
+
+### DO:
+- ✅ **Start with "why"** - Clearly state the problem
+- ✅ **Define success** - Specific, measurable criteria
+- ✅ **Include constraints** - Technical, time, resource
+- ✅ **Show examples** - Inspiration, references
+- ✅ **Get buy-in early** - Review draft with stakeholders
+- ✅ **Keep it concise** - 2-3 pages maximum
+- ✅ **Make it visual** - Include diagrams, mockups, references
+
+### DON'T:
+- ❌ **Jump to solutions** - Focus on problem first
+- ❌ **Be vague** - "Make it better" isn't helpful
+- ❌ **Ignore constraints** - They shape the solution
+- ❌ **Work in isolation** - Involve PM, Engineering early
+- ❌ **Skip research** - Base decisions on data
+- ❌ **Forget accessibility** - Consider from the start
+
+---
+
+## Accessibility in Design Briefs
+
+### Minimum Requirements
+
+**Every design brief should include:**
+
+**WCAG Compliance:**
+- [ ] Target level (A, AA, AAA)
+- [ ] Color contrast requirements (4.5:1 for text)
+- [ ] Keyboard navigation support
+- [ ] Screen reader compatibility
+- [ ] Touch target sizes (44x44px minimum)
+
+**Testing Plan:**
+- [ ] Screen reader testing (NVDA, JAWS, VoiceOver)
+- [ ] Keyboard-only navigation
+- [ ] Color contrast validation
+- [ ] Automated testing (axe, Lighthouse)
+
+See `references/accessibility_guidelines.md` for complete checklist.

+
+## Tips for Designers
+
+### Before Creating the Brief
+
+1. **Talk to stakeholders** - Understand the real problem
+2. **Review existing research** - Don't start from scratch
+3. **Check technical constraints** - Talk to engineering
+4. **Understand the timeline** - Be realistic
+
+### During Brief Creation
+
+1. **Start with template** - Don't reinvent the wheel
+2. **Be specific** - Vague briefs lead to vague designs
+3. **Include visuals** - Mood boards, references, examples
+4. **Define success** - How will you know it worked?
+
+### After Brief Creation
+
+1. **Review with PM** - Align on goals and scope
+2. **Review with Engineering** - Validate feasibility
+3. **Get stakeholder sign-off** - Explicit approval
+4. **Treat it as living doc** - Update as you learn
+
+---
+
+## Common Pitfalls
+
+### Pitfall 1: Too Broad
+
+**Problem:** "Redesign the entire app"
+**Solution:** Break into phases, prioritize
+
+### Pitfall 2: Solution-First
+
+**Problem:** "Make it look like Apple"
+**Solution:** Start with user problems, not aesthetics
+
+### Pitfall 3: No Constraints
+
+**Problem:** Ignoring technical/time limits
+**Solution:** Document and respect constraints
+
+### Pitfall 4: Skipping Research
+
+**Problem:** Designing based on assumptions
+**Solution:** At minimum, review existing data
+
+### Pitfall 5: Vague Success Criteria
+
+**Problem:** "Make it better" isn't measurable
+**Solution:** Define specific, testable criteria
+
+---
+
+## Summary
+
+A great design brief:
+
+1. **Defines the problem** clearly
+2. **Sets goals** and success criteria
+3. **Identifies users** and their needs
+4. **Documents constraints** (time, tech, budget)
+5. **Aligns stakeholders** early
+6. **Guides the work** without being prescriptive
+7. **Evolves** as you learn
+
+**Get started:**
+```bash
+scripts/generate_brief.sh
+```
+
+This creates a solid foundation for successful design projects.

+# Accessibility Guidelines for Design Briefs
+
+Comprehensive accessibility requirements and best practices for design projects.
+
+---
+
+## Why Accessibility Matters
+
+**Legal:** ADA, Section 508, AODA compliance
+**Business:** 15% of the world has a disability - that's your potential users
+**Ethical:** Everyone deserves equal access to digital experiences
+**Technical:** Accessible design is better design for everyone
+
+---
+
+## WCAG 2.1 Overview
+
+### Compliance Levels
+
+**Level A (Minimum):**
+- Basic web accessibility features
+- Legal requirement in many jurisdictions
+- Addresses most critical barriers
+
+**Level AA (Recommended):**
+- Addresses most common barriers
+- Gold standard for most organizations
+- Required by many laws (EU, Canada, US Section 508)
+
+**Level AAA (Enhanced):**
+- Highest level of accessibility
+- Not required for general compliance
+- Often not feasible for all content
+
+**Recommendation:** Target WCAG 2.1 Level AA for most projects.
+
+---
+
+## Four Principles (POUR)
+
+### 1. Perceivable
+Information and UI components must be presentable to users in ways they can perceive.
+
+### 2. Operable
+UI components and navigation must be operable by all users.
+
+### 3. Understandable
+Information and UI operation must be understandable.
+
+### 4. Robust
+Content must be robust enough to work with current and future technologies.
+
+---
+
+## Key Requirements by Category
+
+### Visual Design
+
+#### Color & Contrast
+**Requirement:** Minimum contrast ratios
+- **Normal text:** 4.5:1 (Level AA) or 7:1 (Level AAA)
+- **Large text (18pt+):** 3:1 (Level AA) or 4.5:1 (Level AAA)
+- **UI components:** 3:1 for active elements
+
+**Best Practices:**
+- Don't rely on color alone to convey information
+- Use patterns, icons, or labels in addition to color
+- Test in grayscale to verify information hierarchy
+- Consider color blindness (8% of males, 0.5% of females)
+
+**Tools:**
+- [WebAIM Contrast Checker](https://webaim.org/resources/contrastchecker/)
+- [Contrast Ratio](https://contrast-ratio.com/)
+- Figma plugins: Stark, A11y - Color Contrast Checker
+
+#### Typography
+**Requirements:**
+- Text must be resizable up to 200% without loss of content
+- Line height at least 1.5x font size
+- Paragraph spacing at least 2x font size
+- Letter spacing at least 0.12x font size
+- Word spacing at least 0.16x font size
+
+**Best Practices:**
+- Minimum body text size: 16px
+- Use relative units (rem, em) not absolute (px)
+- Avoid ALL CAPS for long text
+- Left-align text (not justified)
+- Break long content into shorter paragraphs
+- Use clear, simple language
+
+#### Focus Indicators
+**Requirement:** Keyboard focus must be visible
+
+**Best Practices:**
+- Focus indicator contrast ratio: 3:1 minimum
+- Don't remove default focus styles without replacement
+- Use outline or border (not just background color change)
+- Maintain focus order that follows visual layout
+- Show focus on all interactive elements
+
+---
+
+### Interaction Design
+
+#### Keyboard Navigation
+**Requirements:**
+- All functionality available via keyboard
+- No keyboard traps
+- Logical tab order
+- Skip links for repetitive content
+
+**Tab Order:**
+1. Header navigation
+2. Main content
+3. Sidebar (if present)
+4. Footer
+
+**Keyboard Shortcuts:**
+- `Tab` - Move forward through interactive elements
+- `Shift + Tab` - Move backward
+- `Enter` - Activate buttons/links
+- `Space` - Activate buttons, toggle checkboxes
+- `Arrow keys` - Navigate within components (menus, radio groups)
+- `Esc` - Close modals/menus
+
+**Best Practices:**
+- Add "Skip to main content" link
+- Ensure modals trap focus appropriately
+- Return focus when closing overlays
+- Document custom keyboard shortcuts
+
+#### Touch Targets
+**Requirements:**
+- Minimum touch target size: 44×44px (Level AA)
+- Adequate spacing between targets
+
+**Best Practices:**
+- 48×48px or larger for important actions
+- At least 8px spacing between touch targets
+- Enlarge hit areas beyond visible element
+- Consider thumb reach zones on mobile
+
+#### Time Limits
+**Requirements:**
+- Users can extend, adjust, or turn off time limits
+- 20-hour minimum for inactive sessions
+- Warning before timeout
+
+**Best Practices:**
+- Avoid auto-advancing carousels
+- Pause auto-playing media
+- Save user progress
+- Warn 60+ seconds before timeout
+
+#### Motion & Animation
+**Requirements:**
+- Respect `prefers-reduced-motion` setting
+- No flashing content (> 3 flashes/second)
+- Provide pause controls for moving content
+
+**Best Practices:**
+```css
+@media (prefers-reduced-motion: reduce) {
+  * {
+    animation-duration: 0.01ms !important;
+    transition-duration: 0.01ms !important;
+  }
+}
+```
+
+---
+
+### Content & Information
+
+#### Alternative Text
+**Requirements:**
+- All images have alt text
+- Decorative images have empty alt (`alt=""`)
+- Complex images have detailed descriptions
+
+**Alt Text Guidelines:**
+- Describe content and function, not appearance
+- Keep under 150 characters
+- Don't start with "Image of" or "Picture of"
+- For decorative images: `alt=""`
+- For complex diagrams: Use `aria-describedby` or long description
+
+**Examples:**
+- ❌ "Image of a dog"
+- ✅ "Golden retriever playing fetch in a park"
+- ❌ "Click here button"
+- ✅ "Submit registration form"
+
+#### Headings
+**Requirements:**
+- Logical heading structure (H1 → H2 → H3)
+- Don't skip heading levels
+- H1 used once per page
+
+**Best Practices:**
+```html
+<h1>Page Title</h1>
+  <h2>Section 1</h2>
+    <h3>Subsection</h3>
+  <h2>Section 2</h2>
+    <h3>Subsection</h3>
+```
+
+#### Links
+**Requirements:**
+- Link text describes destination
+- Links distinguishable from surrounding text
+
+**Best Practices:**
+- ❌ "Click here" or "Read more"
+- ✅ "Read the design brief guidelines"
+- ❌ URL as link text (https://example.com)
+- ✅ Descriptive text with URL in title
+- Indicate when links open in new windows
+- Underline links in body text
+
+#### Forms
+**Requirements:**
+- Labels for all inputs
+- Error messages clearly identify problems
+- Instructions provided where needed
+- Group related form elements
+
+**Best Practices:**
+```html
+<label for="email">Email Address</label>
+<input id="email" type="email" required
+       aria-describedby="email-hint">
+<span id="email-hint">We'll never share your email</span>
+```
+
+- Place labels above or beside inputs (not inside)
+- Use `<fieldset>` and `<legend>` for groups
+- Provide inline validation
+- Clear error messages with solutions
+- Disable submit until required fields complete
+
+#### Tables
+**Requirements:**
+- Use table headers (`<th>`)
+- Associate headers with data cells
+- Provide table caption or summary
+
+**Best Practices:**
+```html
+<table>
+  <caption>Project Timeline</caption>
+  <thead>
+    <tr>
+      <th scope="col">Phase</th>
+      <th scope="col">Duration</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <th scope="row">Discovery</th>
+      <td>2 weeks</td>
+    </tr>
+  </tbody>
+</table>
+```
+
+---
+
+### Component-Specific Guidelines
+
+#### Modals & Dialogs
+- Focus first element when opened
+- Trap focus within modal
+- Close with Esc key
+- Return focus when closed
+- Use `role="dialog"` and `aria-modal="true"`
+- Provide accessible close button
+
+#### Carousels
+- Pause on hover/focus
+- Keyboard controls to navigate
+- Don't auto-advance (or make stoppable)
+- Indicate current slide
+- All controls keyboard accessible
+
+#### Navigation
+- Skip to main content link
+- Keyboard accessible dropdowns
+- Clear current page indicator
+- Breadcrumb trail when appropriate
+- Mobile menu keyboard accessible
+
+#### Forms with Multiple Steps
+- Indicate current step and total steps
+- Allow navigation between steps
+- Save progress
+- Review before submit
+- Accessible progress indicator
+
+#### Search
+- Label search input clearly
+- Announce results to screen readers
+- Show result count
+- Support keyboard navigation of results
+
+---
+
+## Screen Reader Considerations
+
+### ARIA (Accessible Rich Internet Applications)
+
+**Core Principles:**
+1. **Use semantic HTML first** - ARIA should enhance, not replace
+2. **Don't override native semantics**
+3. **All interactive elements must be keyboard accessible**
+4. **Don't use ARIA to make elements focusable**
+
+**Common ARIA Attributes:**
+
+```html
+<!-- Landmarks -->
+<nav aria-label="Main navigation">
+<main aria-label="Main content">
+<aside aria-label="Related articles">
+
+<!-- Live regions -->
+<div aria-live="polite">Status updated</div>
+<div aria-live="assertive">Error: Invalid input</div>
+
+<!-- Labels & descriptions -->
+<button aria-label="Close dialog">×</button>
+<input aria-describedby="password-requirements">
+
+<!-- States -->
+<button aria-pressed="true">Bold</button>
+<div aria-expanded="false">Menu collapsed</div>
+<input aria-invalid="true">
+```
+
+**Common Roles:**
+- `role="button"` - For clickable non-button elements
+- `role="navigation"` - Navigation landmarks
+- `role="search"` - Search landmarks
+- `role="alert"` - Important messages
+- `role="dialog"` - Modal dialogs
+- `role="tablist"`, `role="tab"`, `role="tabpanel"` - Tab components
+
+### Screen Reader Testing
+
+**Test with:**
+- **NVDA** (Windows, free)
+- **JAWS** (Windows, paid)
+- **VoiceOver** (macOS/iOS, built-in)
+- **TalkBack** (Android, built-in)
+
+**Testing Checklist:**
+- [ ] Can navigate entire page with keyboard alone
+- [ ] All interactive elements announced correctly
+- [ ] Heading structure makes sense
+- [ ] Form labels associated properly
+- [ ] Error messages announced
+- [ ] Dynamic content updates announced
+- [ ] Images have appropriate alt text
+
+---
+
+## Design Handoff Checklist
+
+### For Designers to Specify
+
+- [ ] **Color contrast ratios** for all text and UI elements
+- [ ] **Focus indicator styles** for interactive elements
+- [ ] **Touch target sizes** (minimum 44×44px)
+- [ ] **Alt text** for all meaningful images
+- [ ] **Heading hierarchy** clearly marked
+- [ ] **Form labels** positioned and associated
+- [ ] **Error states** designed and documented
+- [ ] **Keyboard navigation** flow specified
+- [ ] **Motion** alternatives for animations
+- [ ] **Responsive text** sizing behavior
+
+### Documentation to Provide
+
+```markdown
+## Accessibility Specifications
+
+### Color Contrast
+- Primary text on background: 8.2:1 (AAA)
+- Button text on primary color: 5.1:1 (AA)
+- All tested with [tool name]
+
+### Interactive States
+- Default: [specs]
+- Hover: [specs]
+- Focus: 2px solid blue outline, 3:1 contrast
+- Active: [specs]
+- Disabled: [specs]
+
+### Keyboard Navigation
+1. Tab order: Header → CTA → Form → Footer
+2. Skip link to main content
+3. Escape closes modal
+
+### Screen Reader Content
+- "Menu" button: aria-label="Open navigation menu"
+- Close button: aria-label="Close dialog"
+- Loading state: aria-live="polite" announcement
+```
+
+---
+
+## Testing & Validation
+
+### Automated Testing Tools
+
+**Browser Extensions:**
+- [axe DevTools](https://www.deque.com/axe/devtools/) - Free, comprehensive
+- [WAVE](https://wave.webaim.org/) - Visual feedback
+- [Lighthouse](https://developers.google.com/web/tools/lighthouse) - Built into Chrome
+
+**Design Tools:**
+- Figma: Stark, A11y - Focus Orderer
+- Sketch: Stark
+- Adobe XD: Accessibility features built-in
+
+**Limitations:**
+- Automated tools catch ~30-40% of issues
+- Manual testing required for full compliance
+
+### Manual Testing Checklist
+
+- [ ] **Keyboard only** - Can you complete all tasks?
+- [ ] **Screen reader** - Does it make sense?
+- [ ] **Zoom to 200%** - Is content still readable?
+- [ ] **Color blindness** - Information still conveyed?
+- [ ] **Resize text** - Layout still works?
+- [ ] **Disable CSS** - Content still logical?
+- [ ] **Motion reduced** - Animations simplified?
+
+### User Testing with People with Disabilities
+
+**Include diverse participants:**
+- Screen reader users (blind/low vision)
+- Keyboard-only users (motor disabilities)
+- Voice control users
+- Cognitive disabilities
+- Older adults
+- Low bandwidth/assistive tech users
+
+---
+
+## Common Accessibility Mistakes
+
+### ❌ Don't Do This
+
+1. **Using placeholders as labels**
+   ```html
+   <!-- Bad -->
+   <input placeholder="Email address">
+
+   <!-- Good -->
+   <label for="email">Email address</label>
+   <input id="email" type="email">
+   ```
+
+2. **Icon-only buttons without labels**
+   ```html
+   <!-- Bad -->
+   <button><svg>...</svg></button>
+
+   <!-- Good -->
+   <button aria-label="Close menu">
+     <svg aria-hidden="true">...</svg>
+   </button>
+   ```
+
+3. **Disabled buttons without explanation**
+   ```html
+   <!-- Bad -->
+   <button disabled>Submit</button>
+
+   <!-- Good -->
+   <button disabled aria-describedby="submit-hint">Submit</button>
+   <span id="submit-hint">Complete all required fields to submit</span>
+   ```
+
+4. **Auto-playing media**
+   ```html
+   <!-- Bad -->
+   <video autoplay>
+
+   <!-- Good -->
+   <video controls>
+     <track kind="captions" src="captions.vtt">
+   </video>
+   ```
+
+5. **Removing focus indicators**
+   ```css
+   /* Bad */
+   :focus { outline: none; }
+
+   /* Good */
+   :focus {
+     outline: 2px solid blue;
+     outline-offset: 2px;
+   }
+   ```
+

+# Design Principles
+
+A comprehensive guide to establishing and applying design principles for your projects.
+
+---
+
+## What Are Design Principles?
+
+Design principles are foundational guidelines that inform design decisions and help teams create consistent, purposeful user experiences. They serve as:
+
+- **Decision-making tools** - When faced with trade-offs
+- **Alignment mechanisms** - Keep teams on the same page
+- **Communication shortcuts** - Express complex ideas quickly
+- **Quality filters** - Evaluate if designs meet standards
+
+**Key characteristic:** Good principles are opinionated and help you say "no" to things that don't align.
+
+---
+
+## Characteristics of Effective Design Principles
+
+### 1. Specific, Not Generic
+❌ **Bad:** "Keep it simple"
+✅ **Good:** "Show one primary action per screen"
+
+### 2. Opinionated
+❌ **Bad:** "Design should be accessible"
+✅ **Good:** "Accessibility is non-negotiable - WCAG AA minimum"
+
+### 3. Memorable
+- Short and punchy
+- Easy to remember
+- Ideally 3-7 principles total
+
+### 4. Actionable
+- Clear enough to guide decisions
+- Can be applied in practice
+- Include examples of application
+
+### 5. Authentic to Your Product
+- Reflect your unique approach
+- Not copied from others
+- Based on your users and context
+
+---
+
+## Types of Design Principles
+
+### 1. Product-Level Principles
+**Scope:** Entire product or company
+**Duration:** Years
+**Examples:**
+- Google Material Design: "Motion provides meaning"
+- Apple HIG: "Depth creates hierarchy and focus"
+- Shopify Polaris: "Merchants first"
+
+### 2. Project-Level Principles
+**Scope:** Specific feature or initiative
+**Duration:** Weeks to months
+**Examples:**
+- "Mobile-first for this redesign"
+- "Progressive disclosure over feature parity"
+- "Speed trumps beauty for this dashboard"
+
+### 3. Brand Principles
+**Scope:** Visual and tonal identity
+**Duration:** Years
+**Examples:**
+- "Bold but not overwhelming"
+- "Playful but professional"
+- "Technical but approachable"
+
+---
+
+## Framework: Creating Design Principles
+
+### Step 1: Understand Your Context
+
+**Research questions:**
+- Who are our users?
+- What are their core needs?
+- What makes our product unique?
+- What do we want to be known for?
+- What trade-offs do we commonly face?
+
+**Gather input from:**
+- User research findings
+- Stakeholder interviews
+- Competitive analysis
+- Brand strategy
+- Product vision
+
+### Step 2: Identify Themes
+
+**Look for patterns:**
+- Repeated design challenges
+- Common user feedback
+- Successful design decisions
+- Team values and culture
+- Competitive advantages
+
+**Common themes:**
+- Simplicity vs. power
+- Speed vs. features
+- Guidance vs. flexibility
+- Innovation vs. familiarity
+- Delight vs. efficiency
+
+### Step 3: Draft Principles
+
+**Format options:**
+
+**1. Statement + Explanation**
+```
+Principle: Progressive disclosure
+We show complexity only when needed, starting with
+the simplest path and revealing advanced features
+as users need them.
+```
+
+**2. Principle + Sub-points**
+```
+Principle: Speed is a feature
+
+- Optimize for p95 latency < 200ms
+- Perceived performance > actual performance
+- Never block user interactions
+```
+
+**3. Opposites**
+```
+Clarity over cleverness
+We prefer obvious solutions over creative ones
+that require explanation.
+```
+
+### Step 4: Test & Refine
+
+**Validation questions:**
+- Can we apply this to real design decisions?
+- Does it help us choose between options?
+- Is it specific to our product?
+- Can we explain it in 30 seconds?
+- Does the team agree?
+
+**Test with scenarios:**
+- Take recent design decisions
+- Apply principles retroactively
+- Do they guide toward the right choice?
+- Refine based on results
+
+### Step 5: Document & Evangelize
+
+**Documentation should include:**
+- Principle statement
+- Explanation (1-2 paragraphs)
+- Real examples (with images)
+- Anti-examples (what to avoid)
+- When to apply/not apply
+
+---
+
+## Example Design Principles
+
+### Product: Slack
+
+**1. Work hard at being easy**
+Surface the rich capabilities of Slack with progressive disclosure—make the basics easy to understand and the advanced features easy to find.
+
+**2. Empowering, not clever**
+Clarity and usefulness, rather than cleverness, should be our guiding light. We should delight people with ease of use, not tricks.
+
+**3. Courtesy and respect**
+We're mindful of the language and tone in both the product and our communication. We strive for a friendly, supportive voice.
+
+---
+
+### Product: Airbnb
+
+**1. Unified**
+Every part of Airbnb is part of a greater whole. Design cohesively across platforms, features, and touch-points.
+
+**2. Universal**
+Airbnb is used by millions around the world. Make sure your designs scale across cultures and contexts.
+
+**3. Iconic**
+Our interfaces should be instantly recognizable. Leverage consistency and focus to create memorable moments.
+
+**4. Conversational**
+Our voice is friendly and straightforward. Guide users with clarity and warmth.
+
+---
+
+### Product: GOV.UK
+
+**1. Start with user needs**
+Service design starts with identifying user needs. If you don't know what the user needs are, you won't build the right thing.
+
+**2. Do less**
+Government should only do what only government can do. If someone else is doing it, we should point to them.
+
+**3. Design with data**
+In most cases, we can learn from real-world behavior by looking at how existing services are used. Let data drive decision-making.
+
+**4. Do the hard work to make it simple**
+Making something look simple is easy. Making something simple to use is much harder.
+
+**5. Iterate. Then iterate again**
+The best way to build good services is to start small and iterate wildly.
+
+---
+

+
+## Applying Principles to Decisions
+
+### Decision Framework
+
+When facing a design choice:
+
+1. **Identify the trade-off**
+   - What are the options?
+   - What does each optimize for?
+
+2. **Consult principles**
+   - Which principles apply?
+   - What do they suggest?
+
+3. **Make the call**
+   - Principle-aligned decision
+   - Document reasoning
+
+4. **Validate**
+   - Does it feel right?
+   - Can you defend it?
+
+### Example Decision Process
+
+**Scenario:** Should we add a feature request form in-app or direct users to a forum?
+
+**Options:**
+- A: In-app form (more convenient)
+- B: Public forum (builds community)
+
+**Principles:**
+- "Community-driven development"
+- "Transparent by default"
+
+**Decision:** Option B (forum) aligns better with principles of community and transparency.
+
+---
+
+## Principle Templates
+
+### Template 1: Statement + Rationale
+```markdown
+## [Principle Name]
+
+[One sentence principle statement]
+
+**Why this matters:**
+[1-2 paragraphs explaining the reasoning]

+- [Example 2]
+- [Example 3]
+
+**Not this:**
+[Anti-example with explanation]
+```
+
+### Template 2: Principle Pairs
+```markdown
+## [This] over [That]
+
+We prioritize [this] over [that] because [reasoning].
+
+**Example:**
+When [scenario], we choose to [action] rather than
+[alternative action] because it better serves [user need].
+```
+
+### Template 3: Question Format
+```markdown
+## [Question as principle]
+
+[Answer and explanation]

+
+---
+
+### Developer Tool
+
+1. **Documentation first**
+   - Inline code examples
+   - Self-documenting APIs
+   - Error messages that teach
+
+2. **Powerful defaults, maximum flexibility**
+   - Work out-of-box
+   - Expose all config options

+
+## Anti-Patterns to Avoid
+
+### ❌ Too Generic
+"Make it user-friendly"
+- Applies to everything
+- Doesn't guide decisions
+- Basically useless
+
+### ❌ Too Prescriptive

+- Too specific
+- Becomes a rule, not a principle
+- Limits creativity
+
+### ❌ Too Many Principles
+Having 15+ principles
+- Can't remember them
+- Dilutes focus
+- Slows decisions
+
+### ❌ Contradictory Principles
+"Move fast" + "Pixel-perfect polish"
+- Confuses priorities
+- Can't both be true
+- Leads to inconsistency
+
+### ❌ Aspirational but Not Authentic
+Copying Apple's principles for your B2B SaaS
+- Doesn't fit your context
+- Team won't believe it
+- Won't guide real decisions
+
+---
+
+## Maintaining Design Principles

+- Show how they're applied
+
+**Design reviews:**
+- Reference principles explicitly
+- Call out misalignments
+- Celebrate when followed well
+
+**Documentation:**
+- Include in design system
+- Show in component examples
+- Link from design files
+
+---

+
+---
+
+## When to Apply These Principles
+
+These principles apply to:
+- [Context 1]
+- [Context 2]
+
+These principles may not apply when:
+- [Exception 1]
+- [Exception 2]
+
+---
+
+## Decision Framework
+
+When facing a design choice:
+1. Identify the trade-off
+2. Consult relevant principles
+3. Make principle-aligned decision
+4. Document reasoning
+
+---
+
+## Examples of Principles in Action
+
+### Decision 1: [Description]
+**Options:** A or B
+**Principle:** [Which principle applies]
+**Decision:** [What we chose and why]
+
+### Decision 2: [Description]
+[Repeat structure]
+```
+
+---
+
+## Quick Tips
+
+1. **Start broad, refine narrow** - Draft many, pick few
+2. **Test with real scenarios** - Do they actually help?
+3. **Get team buy-in** - Collaborative > dictated
+4. **Show, don't just tell** - Use examples
+5. **Evolve over time** - Principles aren't permanent
+6. **Make them visible** - Post in design files, Slack, etc.
+7. **Use in reviews** - "Does this align with principle X?"
+
+---
+
+**Remember:** Design principles should make decisions easier, not harder. If a principle doesn't help you choose, refine or remove it.

+# User Research Methods
+
+Comprehensive guide to user research methods for design projects.
+
+---
+
+## Why User Research Matters
+
+**Reduces risk:** Validate assumptions before building
+**Saves time:** Fix issues before development
+**Builds empathy:** Understand users deeply
+**Drives decisions:** Data-informed design choices
+**Increases success:** Solutions that actually work
+
+**Rule:** The cost of fixing a problem increases 10x at each stage (design → development → post-launch)
+
+---
+
+## When to Use Which Method
+
+### Discovery Phase (Understanding)
+**Goal:** Learn about users, their context, and needs
+
+**Methods:**
+- User interviews
+- Contextual inquiry
+- Diary studies
+- Surveys
+- Analytics review
+
+**Questions answered:**
+- Who are our users?
+- What are their goals?
+- What problems do they face?
+- How do they currently solve this?
+
+---
+
+### Exploration Phase (Ideation)
+**Goal:** Generate and evaluate design directions
+
+**Methods:**
+- Co-design workshops
+- Card sorting
+- Concept testing
+- Competitive analysis
+- Design critiques
+
+**Questions answered:**
+- What solutions might work?
+- How should we organize information?
+- What do users expect?
+- What works elsewhere?
+
+---
+
+### Validation Phase (Testing)
+**Goal:** Evaluate specific designs before development
+
+**Methods:**
+- Usability testing
+- Prototype testing
+- A/B testing
+- First-click tests
+- Tree testing

+
+# Engineer Expertise Extractor
+
+Extract and document an engineer's coding expertise by analyzing their GitHub contributions, creating a structured knowledge base that captures their coding style, patterns, best practices, and architectural decisions.
+
+## What This Skill Does
+
+Researches an engineer's work to create a "digital mentor" by:
+- **Analyzing Pull Requests** - Extract code patterns, review style, decisions
+- **Extracting Coding Style** - Document their preferences and conventions
+- **Identifying Patterns** - Common solutions and approaches they use
+- **Capturing Best Practices** - Their quality standards and guidelines
+- **Organizing Examples** - Real code samples from their work
+- **Documenting Decisions** - Architectural choices and reasoning
+
+## Why This Matters
+
+**Knowledge Preservation:**
+- Capture expert knowledge before they leave
+- Document tribal knowledge
+- Create mentorship materials
+- Onboard new engineers faster
+
+**Consistency:**
+- Align team coding standards
+- Replicate expert approaches
+- Maintain code quality
+- Scale expertise across team
+
+**Learning:**
+- Learn from senior engineers
+- Understand decision-making

+
+## How It Works
+
+### 1. Research Phase
+Using GitHub CLI (`gh`), the skill:
+- Fetches engineer's pull requests
+- Analyzes code changes
+- Reviews their comments and feedback
+- Extracts patterns and conventions
+- Identifies their expertise areas
+
+### 2. Analysis Phase
+Categorizes findings into:
+- **Coding Style** - Formatting, naming, structure
+- **Patterns** - Common solutions and approaches
+- **Best Practices** - Quality guidelines
+- **Architecture** - Design decisions
+- **Testing** - Testing approaches
+- **Code Review** - Feedback patterns
+- **Documentation** - Doc style and practices
+
+### 3. Organization Phase
+Creates structured folders:
+```

+
+## Output Structure
+
+### Engineer Profile README
+
+**Contains:**
+- Engineer overview
+- Areas of expertise
+- Languages and technologies
+- Key contributions
+- Coding philosophy
+- How to use this profile
+
+### Coding Style Documentation
+
+**Captures:**
+- Naming conventions (variables, functions, classes)
+- Code structure preferences
+- File organization
+- Comment style
+- Formatting preferences
+- Language-specific idioms
+
+**Example:**
+```markdown
+# Coding Style: [Engineer Name]
+
+## Naming Conventions
+
+### Variables
+- Use descriptive names: `userAuthentication` not `ua`
+- Boolean variables: `isActive`, `hasPermission`, `canEdit`
+- Collections: plural names `users`, `items`, `transactions`
+
+### Functions
+- Verb-first: `getUserById`, `validateInput`, `calculateTotal`
+- Pure functions preferred
+- Single responsibility
+
+### Classes
+- PascalCase: `UserService`, `PaymentProcessor`
+- Interface prefix: `IUserRepository`
+- Concrete implementations: `MongoUserRepository`
+
+## Code Structure
+
+### File Organization
+- One class per file
+- Related functions grouped together
+- Tests alongside implementation
+- Clear separation of concerns
+
+### Function Length
+- Max 20-30 lines preferred
+- Extract helper functions
+- Single level of abstraction
+```
+
+### Patterns Documentation
+
+**Captures:**
+- Recurring solutions
+- Design patterns used
+- Architectural patterns
+- Problem-solving approaches
+
+**Example:**
+```markdown
+# Common Patterns: [Engineer Name]
+
+## Dependency Injection
+
+Used consistently across services:
+
+\`\`\`typescript
+// Pattern: Constructor injection
+class UserService {
+  constructor(
+    private readonly userRepo: IUserRepository,
+    private readonly logger: ILogger
+  ) {}
+}
+\`\`\`
+
+**Why:** Testability, loose coupling, clear dependencies
+
+## Error Handling
+
+Consistent error handling approach:
+
+\`\`\`typescript
+// Pattern: Custom error types + global handler
+class ValidationError extends Error {
+  constructor(message: string) {
+    super(message);
+    this.name = 'ValidationError';
+  }
+}
+
+// Usage
+if (!isValid(input)) {
+  throw new ValidationError('Invalid input format');
+}
+\`\`\`
+
+**Why:** Type-safe errors, centralized handling, clear debugging
+```
+
+### Best Practices Documentation
+
+**Captures:**
+- Quality standards
+- Testing approaches
+- Performance guidelines
+- Security practices
+- Documentation standards
+
+**Example:**
+```markdown
+# Best Practices: [Engineer Name]
+
+## Testing
+
+### Unit Test Structure
+- AAA pattern (Arrange, Act, Assert)
+- One assertion per test preferred
+- Test names describe behavior
+- Mock external dependencies
+
+\`\`\`typescript
+describe('UserService', () => {
+  describe('createUser', () => {
+    it('should create user with valid data', async () => {
+      // Arrange
+      const userData = { email: 'test@example.com', name: 'Test' };
+      const mockRepo = createMockRepository();
+
+      // Act
+      const result = await userService.createUser(userData);
+
+      // Assert
+      expect(result.id).toBeDefined();
+      expect(result.email).toBe(userData.email);
+    });
+  });
+});
+\`\`\`
+
+### Test Coverage
+- Aim for 80%+ coverage
+- 100% coverage for critical paths
+- Integration tests for APIs
+- E2E tests for user flows
+
+## Code Review Standards
+
+### What to Check
+- [ ] Tests included and passing
+- [ ] No console.logs remaining
+- [ ] Error handling present
+- [ ] Comments explain "why" not "what"
+- [ ] No hardcoded values
+- [ ] Security considerations addressed
+```
+
+### Architecture Documentation
+
+**Captures:**
+- Design decisions
+- Technology choices
+- Trade-offs made
+- System design approaches
+
+**Example:**
+```markdown
+# Architectural Decisions: [Engineer Name]
+
+## Decision: Microservices vs Monolith
+
+**Context:** Scaling user service
+**Decision:** Start monolith, extract services when needed
+**Reasoning:**
+- Team size: 5 engineers
+- Product stage: MVP
+- Premature optimization risk
+- Easier debugging and deployment
+
+**Trade-offs:**
+- Monolith pros: Simpler, faster development
+- Monolith cons: Harder to scale later
+- Decision: Optimize for current needs, refactor when hitting limits
+
+## Decision: REST vs GraphQL
+
+**Context:** API design for mobile app
+**Decision:** REST with versioning
+**Reasoning:**
+- Team familiar with REST
+- Simple use cases
+- Caching easier
+- Over-fetching not a problem yet
+
+**When to reconsider:** If frontend needs complex queries
+```
+
+### Code Review Documentation
+
+**Captures:**
+- Feedback patterns
+- Review approach
+- Common suggestions
+- Communication style
+
+**Example:**
+```markdown
+# Code Review Style: [Engineer Name]
+
+## Review Approach
+
+### Priority Order
+1. Security vulnerabilities
+2. Logic errors
+3. Test coverage
+4. Code structure
+5. Naming and style
+
+### Feedback Style
+- Specific and constructive
+- Explains "why" behind suggestions
+- Provides examples
+- Asks questions to understand reasoning
+
+### Common Suggestions
+
+**Security:**
+- "Consider input validation here"
+- "This query is vulnerable to SQL injection"
+- "Should we rate-limit this endpoint?"
+
+**Performance:**
+- "This N+1 query could be optimized with a join"
+- "Consider caching this expensive operation"
+- "Memoize this pure function"
+
+**Testing:**
+- "Can we add a test for the error case?"
+- "What happens if the API returns null?"
+- "Let's test the boundary conditions"
+
+**Code Quality:**
+- "Can we extract this into a helper function?"
+- "This function is doing too many things"
+- "Consider a more descriptive variable name"
+```

+
+## Profile Usage by Agents
+
+When an agent has access to an engineer profile, it can:
+
+**Code Generation:**
+- Follow extracted naming conventions
+- Use identified patterns
+- Apply documented best practices
+- Match architectural style
+
+**Code Review:**
+- Provide feedback in engineer's style
+- Check for common issues they'd catch
+- Apply their quality standards
+- Match their priorities
+
+**Problem Solving:**
+- Use their common solutions
+- Follow their architectural approach
+- Apply their design patterns
+- Consider their trade-offs
+
+**Example Agent Prompt:**
+```
+"Using the profile at engineer_profiles/senior_dev/, write a user service
+following their coding style, patterns, and best practices. Pay special
+attention to their error handling approach and testing standards."
+```
+
+## Best Practices
+
+### Research Ethics
+
+**DO:**
+- ✅ Get permission before extracting
+- ✅ Focus on public contributions
+- ✅ Respect privacy
+- ✅ Use for learning and improvement
+
+**DON'T:**
+- ❌ Extract without permission
+- ❌ Share profiles externally
+- ❌ Include sensitive information
+- ❌ Use for performance reviews
+
+### Profile Maintenance
+
+**Regular Updates:**
+- Refresh every quarter
+- Add new significant PRs
+- Update with latest patterns
+- Archive outdated practices
+
+**Quality Control:**
+- Verify extracted patterns
+- Review examples for relevance
+- Update documentation
+- Remove deprecated practices
+
+### Effective Usage
+
+**For Learning:**
+- Study patterns with context
+- Understand reasoning behind choices
+- Practice applying techniques
+- Ask questions when unclear
+
+**For Replication:**
+- Start with style guide
+- Reference patterns for similar problems
+- Adapt to current context
+- Don't blindly copy
+
+## Limitations
+
+**What This Extracts:**
+- ✅ Coding style and conventions
+- ✅ Common patterns and approaches
+- ✅ Best practices and guidelines
+- ✅ Architectural decisions
+- ✅ Review feedback patterns
+
+**What This Doesn't Capture:**
+- ❌ Real-time problem-solving process
+- ❌ Verbal communication style
+- ❌ Meeting discussions
+- ❌ Design phase thinking
+- ❌ Interpersonal mentoring
+
+## Future Enhancements
+
+**Potential additions:**
+- Slack message analysis (communication style)
+- Design doc extraction (design thinking)
+- Meeting notes analysis (decision process)
+- Video analysis (pair programming sessions)
+- Code metrics tracking (evolution over time)

+---
+
+# Engineer Skill Creator
+
+Transform extracted engineer profiles into ready-to-use skills with progressive disclosure, enabling AI agents to efficiently find and apply the right expertise for any coding task.
+
+## What This Skill Does
+
+Takes the output from **engineer-expertise-extractor** and creates a structured, queryable skill that:
+- **Organizes expertise by task type** - Find relevant patterns quickly
+- **Uses progressive disclosure** - Show only what's needed for current task
+- **Provides contextual examples** - Real code samples for specific scenarios
+- **Guides agents intelligently** - Help find the right expertise at the right time
+- **Enables task-specific queries** - "How would they handle authentication?"
+
+## The Two-Step Process
+
+### Step 1: Extract (engineer-expertise-extractor)
+```bash
+./extract_engineer.sh senior_dev
+# Output: engineer_profiles/senior_dev/
+```
+
+### Step 2: Create Skill (THIS SKILL)
+```bash
+./create_expert_skill.sh senior_dev
+# Output: expert-skills/senior-dev-mentor/
+```
+
+**Result:** A ready-to-use skill that agents can query for specific guidance.
+
+## Why Progressive Disclosure Matters
+
+**Without progressive disclosure:**
+- Agent gets all expertise at once (overwhelming)
+- Hard to find relevant information
+- Context limits reached quickly
+- Inefficient and slow
+
+**With progressive disclosure:**
+- Agent asks specific question
+- Gets only relevant expertise
+- Focused, actionable guidance
+- Efficient use of context
+- Faster, better results
+
+## Output Structure
+
+When you create a skill from an engineer profile, you get:

+
+```markdown
+# Authentication - Senior Dev's Approach
+
+## Overview
+How senior_dev implements authentication based on 15 PRs analyzed.
+
+## Preferred Approach
+- JWT-based authentication
+- Refresh token rotation
+- HttpOnly cookies for web
+- Token in headers for mobile/API
+
+## Implementation Pattern
+
+### Service Structure
+[Code example from their PR #1234]
+
+### Token Generation
+[Code example from their PR #5678]
+
+### Token Validation
+[Code example from their PR #9012]
+
+## Testing Approach
+- Unit tests for token generation
+- Integration tests for auth flow
+- Security tests for token validation
+
+[Test examples from their code]
+
+## Security Considerations
+From their code reviews:
+- Always validate token signature
+- Check expiration
+- Implement rate limiting
+- Use secure random for secrets
+
+## Common Pitfalls They Avoid
+- Storing tokens in localStorage (XSS risk)
+- Not rotating refresh tokens
+- Weak secret keys
+- Missing token expiration
+
+## Related Patterns
+- Error handling for auth failures
+- Middleware pattern for auth checks
+- Repository pattern for user lookup
+
+## Examples
+See: examples/authentication_service.ts
+```
+
+## Use Cases

+**Problem:** How would senior dev approach this specific problem?
+
+**Solution:**
+```
+"Using expert-skills/tech-lead-mentor/, how do I handle rate limiting?"
+```
+
+**Result:** Their specific approach, examples, and reasoning
+
+### 3. Code Review Training
+
+**Problem:** Learn what experienced engineer looks for
+
+**Solution:**
+```

+
+# Frontend Designer
+
+A comprehensive skill for frontend designers and developers to build beautiful, accessible, and performant user interfaces with modern best practices.
+
+## What This Skill Does
+
+Helps frontend designers/developers with:
+- **Component Design & Development** - Build reusable, accessible components
+- **Design Systems** - Implement tokens, patterns, and documentation
+- **Responsive Design** - Mobile-first, fluid layouts
+- **Accessibility (WCAG 2.1)** - Inclusive design patterns
+- **Modern CSS** - Flexbox, Grid, custom properties
+- **Performance Optimization** - Fast, efficient frontends
+- **Framework Patterns** - React, Vue, Svelte best practices
+- **Design-to-Code** - Figma to production workflows
+
+## Why This Skill Matters
+
+**Without systematic approach:**
+- Inconsistent component implementations
+- Accessibility issues
+- Poor responsive behavior
+- Duplicate code and styles
+- Hard to maintain
+- Performance problems
+
+**With this skill:**
+- Consistent, reusable components
+- WCAG AA compliant by default
+- Mobile-first responsive design

+## Component Patterns
+
+### Button Component
+
+**Accessible, flexible button pattern:**
+
+```tsx
+// React example
+interface ButtonProps {
+  variant?: 'primary' | 'secondary' | 'ghost';
+  size?: 'sm' | 'md' | 'lg';
+  disabled?: boolean;
+  loading?: boolean;
+  children: React.ReactNode;
+  onClick?: () => void;
+}
+
+export const Button: React.FC<ButtonProps> = ({
+  variant = 'primary',
+  size = 'md',
+  disabled = false,
+  loading = false,
+  children,
+  onClick,
+  ...props
+}) => {
+  return (
+    <button
+      className={`btn btn--${variant} btn--${size}`}
+      disabled={disabled || loading}
+      onClick={onClick}
+      aria-busy={loading}
+      {...props}
+    >
+      {loading ? <Spinner /> : children}
+    </button>
+  );
+};
+```
+
+**CSS (with design tokens):**
+
+```css
+.btn {
+  /* Base styles */
+  display: inline-flex;
+  align-items: center;
+  justify-content: center;
+  gap: var(--space-2);
+
+  font-family: var(--font-sans);
+  font-weight: 600;
+  text-decoration: none;
+
+  border: none;
+  border-radius: var(--radius-md);
+  cursor: pointer;
+
+  transition: all 0.2s ease;
+
+  /* Accessibility */
+  min-height: 44px; /* WCAG touch target */
+
+  &:focus-visible {
+    outline: 2px solid var(--color-focus);
+    outline-offset: 2px;
+  }
+
+  &:disabled {
+    opacity: 0.5;
+    cursor: not-allowed;
+  }
+}
+
+/* Variants */
+.btn--primary {
+  background: var(--color-primary);
+  color: var(--color-on-primary);
+
+  &:hover:not(:disabled) {
+    background: var(--color-primary-hover);
+  }
+}
+
+.btn--secondary {
+  background: var(--color-secondary);
+  color: var(--color-on-secondary);
+}
+
+.btn--ghost {
+  background: transparent;
+  color: var(--color-primary);
+  border: 1px solid currentColor;
+}
+
+/* Sizes */
+.btn--sm {
+  padding: var(--space-2) var(--space-3);
+  font-size: var(--text-sm);
+}
+
+.btn--md {
+  padding: var(--space-3) var(--space-4);
+  font-size: var(--text-base);
+}
+
+.btn--lg {
+  padding: var(--space-4) var(--space-6);
+  font-size: var(--text-lg);
+}
+```
+
+### Card Component
+
+**Flexible, accessible card:**
+
+```tsx
+interface CardProps {
+  variant?: 'elevated' | 'outlined' | 'filled';
+  padding?: 'none' | 'sm' | 'md' | 'lg';
+  interactive?: boolean;
+  children: React.ReactNode;
+}
+
+export const Card: React.FC<CardProps> = ({
+  variant = 'elevated',
+  padding = 'md',
+  interactive = false,
+  children,
+}) => {
+  const Component = interactive ? 'button' : 'div';
+
+  return (
+    <Component
+      className={`
+        card
+        card--${variant}
+        card--padding-${padding}
+        ${interactive ? 'card--interactive' : ''}
+      `}
+      {...(interactive && { role: 'button', tabIndex: 0 })}
+    >
+      {children}
+    </Component>
+  );
+};
+```
+
+**CSS:**
+
+```css
+.card {
+  border-radius: var(--radius-lg);
+  background: var(--color-surface);
+}
+
+.card--elevated {
+  box-shadow: var(--shadow-md);
+}
+
+.card--outlined {
+  border: 1px solid var(--color-border);
+}
+
+.card--filled {
+  background: var(--color-surface-variant);
+}
+
+.card--interactive {
+  cursor: pointer;
+  transition: transform 0.2s, box-shadow 0.2s;
+
+  &:hover {
+    transform: translateY(-2px);
+    box-shadow: var(--shadow-lg);
+  }
+
+  &:focus-visible {
+    outline: 2px solid var(--color-focus);
+    outline-offset: 2px;
+  }
+}
+
+.card--padding-sm { padding: var(--space-3); }
+.card--padding-md { padding: var(--space-4); }
+.card--padding-lg { padding: var(--space-6); }
+```
+
+### Form Input Component
+
+**Accessible form input:**
+
+```tsx
+interface InputProps {
+  label: string;
+  error?: string;
+  hint?: string;
+  required?: boolean;
+  type?: 'text' | 'email' | 'password' | 'number';
+}
+
+export const Input: React.FC<InputProps> = ({
+  label,
+  error,
+  hint,
+  required = false,
+  type = 'text',
+  ...props
+}) => {
+  const id = useId();
+  const hintId = `${id}-hint`;
+  const errorId = `${id}-error`;
+
+  return (
+    <div className="input-wrapper">
+      <label htmlFor={id} className="input-label">
+        {label}
+        {required && <span aria-label="required">*</span>}
+      </label>
+
+      {hint && (
+        <p id={hintId} className="input-hint">
+          {hint}
+        </p>
+      )}
+
+      <input
+        id={id}
+        type={type}
+        className={`input ${error ? 'input--error' : ''}`}
+        aria-required={required}
+        aria-invalid={!!error}
+        aria-describedby={error ? errorId : hint ? hintId : undefined}
+        {...props}
+      />
+
+      {error && (
+        <p id={errorId} className="input-error" role="alert">
+          {error}
+        </p>
+      )}
+    </div>
+  );
+};
+```

+
+## Responsive Design Patterns
+
+### Mobile-First Breakpoints
+
+```css
+/* Mobile-first approach */
+.container {
+  padding: var(--space-4);
+
+  /* Tablet: 768px and up */
+  @media (min-width: 48rem) {
+    padding: var(--space-6);
+  }
+
+  /* Desktop: 1024px and up */
+  @media (min-width: 64rem) {
+    padding: var(--space-8);
+    max-width: 1200px;
+    margin: 0 auto;
+  }
+}
+```
+
+### Fluid Typography
+
+```css
+/* Responsive typography */
+h1 {
+  font-size: clamp(2rem, 5vw, 3.5rem);
+  line-height: var(--leading-tight);
+}
+
+h2 {
+  font-size: clamp(1.5rem, 4vw, 2.5rem);
+}
+
+p {
+  font-size: clamp(1rem, 2vw, 1.125rem);
+  line-height: var(--leading-normal);
+}
+```
+
+### Grid Layouts
+
+```css
+/* Responsive grid */
+.grid {
+  display: grid;
+  gap: var(--space-4);
+
+  /* Auto-fit columns (min 280px) */
+  grid-template-columns: repeat(auto-fit, minmax(280px, 1fr));
+}
+
+/* 12-column grid system */
+.grid-12 {
+  display: grid;
+  grid-template-columns: repeat(12, 1fr);
+  gap: var(--space-4);
+}
+
+.col-span-4 {
+  grid-column: span 4;
+}
+
+/* Stack on mobile */
+@media (max-width: 48rem) {
+  .col-span-4 {
+    grid-column: span 12;
+  }
+}
+```
+
+## Accessibility Patterns
+
+### Skip Links
+
+```tsx
+export const SkipLink = () => (
+  <a href="#main-content" className="skip-link">
+    Skip to main content
+  </a>
+);
+```
+
+```css
+.skip-link {
+  position: absolute;
+  top: -40px;
+  left: 0;
+  background: var(--color-primary);
+  color: var(--color-on-primary);
+  padding: var(--space-2) var(--space-4);
+  text-decoration: none;
+  z-index: 100;
+
+  &:focus {
+    top: 0;
+  }
+}
+```
+
+### Focus Management
+
+```tsx
+// Modal with focus trap
+export const Modal = ({ isOpen, onClose, children }) => {
+  const modalRef = useRef(null);
+
+  useEffect(() => {
+    if (isOpen) {
+      // Save currently focused element
+      const previouslyFocused = document.activeElement;
+
+      // Focus first focusable element in modal
+      const firstFocusable = modalRef.current?.querySelector(
+        'button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])'
+      );
+      firstFocusable?.focus();
+
+      // Restore focus on close
+      return () => previouslyFocused?.focus();
+    }
+  }, [isOpen]);
+
+  if (!isOpen) return null;
+
+  return (
+    <div
+      ref={modalRef}
+      role="dialog"
+      aria-modal="true"
+      className="modal-overlay"
+    >
+      <div className="modal">
+        {children}
+      </div>
+    </div>
+  );
+};
+```
+
+### ARIA Labels
+
+```tsx
+// Icon button with accessible label
+export const IconButton = ({ icon, label, ...props }) => (
+  <button
+    aria-label={label}
+    className="icon-button"
+    {...props}
+  >
+    <span aria-hidden="true">{icon}</span>
+  </button>
+);
+
+// Loading state
+export const LoadingButton = ({ loading, children, ...props }) => (
+  <button
+    aria-busy={loading}
+    aria-live="polite"
+    disabled={loading}
+    {...props}
+  >
+    {loading ? 'Loading...' : children}
+  </button>
+);
+```
+
+## Performance Optimization
+
+### Critical CSS
+
+```html
+<!-- Inline critical CSS -->
+<style>
+  /* Above-the-fold styles */
+  body { margin: 0; font-family: var(--font-sans); }
+  .header { /* critical header styles */ }
+  .hero { /* critical hero styles */ }
+</style>
+
+<!-- Load full stylesheet async -->
+<link rel="stylesheet" href="styles.css" media="print" onload="this.media='all'">
+```
+
+### Lazy Loading Images
+
+```tsx
+export const LazyImage = ({ src, alt, ...props }) => (
+  <img
+    src={src}
+    alt={alt}
+    loading="lazy"
+    decoding="async"
+    {...props}
+  />
+);
+```
+
+### Code Splitting
+
+```tsx
+// React lazy loading
+const Dashboard = lazy(() => import('./Dashboard'));
+
+function App() {
+  return (
+    <Suspense fallback={<Loading />}>
+      <Dashboard />
+    </Suspense>
+  );
+}
+```
+
+## Modern CSS Techniques
+
+### Container Queries
+
+```css
+.card {
+  container-type: inline-size;
+}
+
+.card-content {
+  display: flex;
+  flex-direction: column;
+
+  /* Switch to row layout when container > 400px */
+  @container (min-width: 400px) {
+    flex-direction: row;
+  }
+}
+```
+
+### CSS Grid Auto-Fit
+
+```css
+.gallery {
+  display: grid;
+  grid-template-columns: repeat(auto-fit, minmax(250px, 1fr));
+  gap: var(--space-4);
+}
+```
+
+### Custom Properties for Theming
+
+```css
+/* Light theme (default) */
+:root {
+  --bg: #ffffff;
+  --text: #000000;
+}
+
+/* Dark theme */
+[data-theme="dark"] {
+  --bg: #000000;
+  --text: #ffffff;
+}
+
+body {
+  background: var(--bg);
+  color: var(--text);
+}
+```

+
+## Using This Skill
+
+### Generate Component
+
+```bash
+./scripts/generate_component.sh Button
+```
+
+Creates component with:
+- TypeScript/JSX file
+- CSS module
+- Test file
+- Storybook story
+- Accessibility checks
+
+### Design System Setup
+
+```bash
+./scripts/setup_design_system.sh
+```
+
+Creates:
+- Design tokens (CSS custom properties)
+- Base styles
+- Component templates
+- Documentation structure
+
+### Accessibility Audit
+
+```bash
+./scripts/audit_accessibility.sh
+```
+
+Checks:
+- Color contrast ratios
+- Keyboard navigation
+- ARIA attributes
+- Semantic HTML
+- Focus management
+
+## Best Practices
+
+### Component Design
+
+✅ **DO:**
+- Use semantic HTML
+- Make components keyboard accessible
+- Provide ARIA labels
+- Support both light and dark modes
+- Make touch targets 44x44px minimum
+- Use proper heading hierarchy
+- Handle loading and error states
+
+❌ **DON'T:**
+- Use divs for buttons
+- Forget focus styles
+- Hard-code colors
+- Ignore mobile viewports
+- Skip alt text on images
+- Create inaccessible modals
+
+### CSS Best Practices
+
+✅ **DO:**
+- Use design tokens
+- Mobile-first responsive
+- BEM or CSS modules for naming
+- Logical properties (inline-start vs left)
+- Modern layout (flexbox, grid)
+
+❌ **DON'T:**
+- Use !important
+- Deep nesting (> 3 levels)
+- Fixed pixel values everywhere
+- Browser-specific hacks
+- Inline styles
+
+### Performance
+
+✅ **DO:**
+- Lazy load images
+- Code split routes
+- Minimize CSS
+- Use system fonts
+- Optimize images (WebP)
+- Critical CSS inline
+
+❌ **DON'T:**
+- Load unused CSS
+- Large JavaScript bundles
+- Unoptimized images
+- Blocking resources
+- Too many web fonts
+
+## Framework-Specific Patterns
+
+### React
+
+```tsx
+// Composition pattern
+export const Card = ({ children }) => (
+  <div className="card">{children}</div>
+);
+
+export const CardHeader = ({ children }) => (
+  <div className="card-header">{children}</div>
+);
+
+// Usage
+<Card>
+  <CardHeader>Title</CardHeader>
+  <CardBody>Content</CardBody>
+</Card>
+```
+
+### Vue
+
+```vue
+<!-- Composable component -->
+<template>
+  <div :class="cardClasses">
+    <slot />
+  </div>
+</template>
+
+<script setup>
+const props = defineProps({
+  variant: String,
+  padding: String
+});
+
+const cardClasses = computed(() => [
+  'card',
+  `card--${props.variant}`,
+  `card--padding-${props.padding}`
+]);
+</script>
+```

+# Component Library Architecture
+
+Complete guide to building, organizing, and maintaining a scalable component library.
+
+## Component Architecture Principles
+
+### 1. Atomic Design
+
+Organize components hierarchically from smallest to largest.
+
+**Hierarchy:**
+```
+Atoms → Molecules → Organisms → Templates → Pages
+```
+
+**Example Structure:**
+```
+components/
+├── atoms/
+│   ├── Button/
+│   ├── Input/
+│   ├── Icon/
+│   └── Label/
+├── molecules/
+│   ├── FormField/
+│   ├── SearchBar/
+│   └── Card/
+├── organisms/
+│   ├── Header/
+│   ├── LoginForm/
+│   └── ProductCard/
+├── templates/
+│   ├── DashboardLayout/
+│   └── AuthLayout/
+└── pages/
+    ├── HomePage/
+    └── ProfilePage/
+```
+
+### 2. Component Types
+
+**Presentational (Dumb) Components:**
+- Focus on how things look
+- No state management
+- Receive data via props
+- Highly reusable
+
+```tsx
+// Presentational Button
+interface ButtonProps {
+  variant?: 'primary' | 'secondary';
+  size?: 'sm' | 'md' | 'lg';
+  children: React.ReactNode;
+  onClick?: () => void;
+}
+
+export const Button: React.FC<ButtonProps> = ({
+  variant = 'primary',
+  size = 'md',
+  children,
+  onClick,
+}) => {
+  return (
+    <button
+      className={`btn btn--${variant} btn--${size}`}
+      onClick={onClick}
+    >
+      {children}
+    </button>
+  );
+};
+```
+
+**Container (Smart) Components:**
+- Focus on how things work
+- Manage state
+- Connect to data sources
+- Use presentational components
+
+```tsx
+// Container Component
+export const UserProfileContainer: React.FC = () => {
+  const [user, setUser] = useState<User | null>(null);
+  const [loading, setLoading] = useState(true);
+
+  useEffect(() => {
+    fetchUser().then(data => {
+      setUser(data);
+      setLoading(false);
+    });
+  }, []);
+
+  if (loading) return <LoadingSpinner />;
+  if (!user) return <ErrorMessage />;
+
+  return <UserProfile user={user} />;
+};
+```
+
+### 3. Component Composition
+
+**Build complex components from simple ones.**
+
+```tsx
+// Atoms
+const Avatar: React.FC<AvatarProps> = ({ src, alt }) => (
+  <img className="avatar" src={src} alt={alt} />
+);
+
+const Badge: React.FC<BadgeProps> = ({ children }) => (
+  <span className="badge">{children}</span>
+);
+
+// Molecule (composed of atoms)
+const UserBadge: React.FC<UserBadgeProps> = ({ user }) => (
+  <div className="user-badge">
+    <Avatar src={user.avatar} alt={user.name} />
+    <span className="user-badge__name">{user.name}</span>
+    <Badge>{user.role}</Badge>
+  </div>
+);
+
+// Organism (composed of molecules)
+const UserList: React.FC<UserListProps> = ({ users }) => (
+  <ul className="user-list">
+    {users.map(user => (
+      <li key={user.id}>
+        <UserBadge user={user} />
+      </li>
+    ))}
+  </ul>
+);
+```

+        role="dialog"
+        aria-modal="true"
+        aria-labelledby={title ? 'modal-title' : undefined}
+      >
+        {title && (
+          <div className="modal__header">
+            <h2 id="modal-title">{title}</h2>

+}
+
+export const Dropdown: React.FC<DropdownProps> = ({
+  trigger,
+  children,
+  align = 'left',
+}) => {
+  const [open, setOpen] = useState(false);
+  const dropdownRef = useRef<HTMLDivElement>(null);
+
+  useEffect(() => {
+    const handleClickOutside = (event: MouseEvent) => {
+      if (
+        dropdownRef.current &&
+        !dropdownRef.current.contains(event.target as Node)
+      ) {
+        setOpen(false);
+      }
+    };
+
+    document.addEventListener('mousedown', handleClickOutside);
+    return () => document.removeEventListener('mousedown', handleClickOutside);

+
+  return (
+    <div className="dropdown" ref={dropdownRef}>
+      <button
+        className="dropdown__trigger"
+        onClick={() => setOpen(!open)}
+        aria-expanded={open}
+        aria-haspopup="true"
+      >
+        {trigger}
+      </button>
+
+      {open && (
+        <div className={`dropdown__menu dropdown__menu--${align}`} role="menu">
+          {children}
+        </div>
+      )}
+    </div>
+  );
+};
+```
+
+## Component Patterns
+
+### 1. Compound Components
+
+**Allow components to work together while sharing implicit state.**
+
+```tsx
+// Context for shared state
+const AccordionContext = createContext<{
+  activeIndex: number | null;
+  setActiveIndex: (index: number | null) => void;
+} | null>(null);
+
+// Parent component
+export const Accordion: React.FC<{ children: React.ReactNode }> = ({
+  children,
+}) => {
+  const [activeIndex, setActiveIndex] = useState<number | null>(null);
+
+  return (
+    <AccordionContext.Provider value={{ activeIndex, setActiveIndex }}>
+      <div className="accordion">{children}</div>
+    </AccordionContext.Provider>
+  );
+};
+
+// Child component
+export const AccordionItem: React.FC<{
+  index: number;
+  title: string;
+  children: React.ReactNode;
+}> = ({ index, title, children }) => {
+  const context = useContext(AccordionContext);
+  if (!context) throw new Error('AccordionItem must be used within Accordion');
+
+  const { activeIndex, setActiveIndex } = context;
+  const isOpen = activeIndex === index;
+
+  return (
+    <div className="accordion-item">
+      <button
+        className="accordion-item__header"
+        onClick={() => setActiveIndex(isOpen ? null : index)}
+        aria-expanded={isOpen}
+      >
+        {title}
+      </button>
+
+      {isOpen && <div className="accordion-item__content">{children}</div>}
+    </div>
+  );
+};
+
+// Usage
+<Accordion>
+  <AccordionItem index={0} title="Section 1">Content 1</AccordionItem>
+  <AccordionItem index={1} title="Section 2">Content 2</AccordionItem>
+</Accordion>
+```
+
+### 2. Render Props
+
+**Pass rendering logic as a prop.**
+
+```tsx
+interface DataFetcherProps<T> {
+  url: string;
+  children: (data: {
+    data: T | null;
+    loading: boolean;
+    error: Error | null;
+  }) => React.ReactNode;
+}
+
+export function DataFetcher<T>({ url, children }: DataFetcherProps<T>) {
+  const [data, setData] = useState<T | null>(null);
+  const [loading, setLoading] = useState(true);
+  const [error, setError] = useState<Error | null>(null);
+
+  useEffect(() => {
+    fetch(url)
+      .then(res => res.json())
+      .then(setData)
+      .catch(setError)
+      .finally(() => setLoading(false));
+  }, [url]);
+
+  return <>{children({ data, loading, error })}</>;
+}
+
+// Usage
+<DataFetcher<User> url="/api/user">
+  {({ data, loading, error }) => {
+    if (loading) return <LoadingSpinner />;
+    if (error) return <ErrorMessage error={error} />;
+    if (!data) return null;
+    return <UserProfile user={data} />;
+  }}
+</DataFetcher>
+```
+
+### 3. Custom Hooks Pattern
+
+**Extract reusable logic into custom hooks.**
+
+```tsx
+// useToggle hook
+export function useToggle(initialValue = false) {
+  const [value, setValue] = useState(initialValue);
+
+  const toggle = useCallback(() => setValue(v => !v), []);
+  const setTrue = useCallback(() => setValue(true), []);
+  const setFalse = useCallback(() => setValue(false), []);
+
+  return { value, toggle, setTrue, setFalse };
+}
+
+// Usage in component
+export const Modal: React.FC<ModalProps> = ({ children }) => {
+  const { value: isOpen, setTrue: open, setFalse: close } = useToggle();
+
+  return (
+    <>
+      <button onClick={open}>Open Modal</button>
+      {isOpen && (
+        <div className="modal">
+          {children}
+          <button onClick={close}>Close</button>
+        </div>
+      )}
+    </>
+  );
+};
+```
+
+## Styling Strategies
+
+### 1. CSS Modules
+
+```css
+/* Button.module.css */
+.button {
+  display: inline-flex;
+  align-items: center;
+  padding: var(--space-3) var(--space-4);
+  border-radius: var(--radius-md);
+}
+
+.button--primary {
+  background: var(--color-primary);
+  color: var(--color-white);
+}
+
+.button--secondary {
+  background: transparent;
+  color: var(--color-primary);
+  border: 1px solid var(--color-primary);
+}
+```
+
+```tsx
+import styles from './Button.module.css';
+
+export const Button = ({ variant }) => (
+  <button className={`${styles.button} ${styles[`button--${variant}`]}`}>
+    Click me
+  </button>
+);
+```
+
+### 2. CSS-in-JS (Styled Components)
+
+```tsx
+import styled from 'styled-components';
+
+const StyledButton = styled.button<{ variant: string }>`
+  display: inline-flex;
+  align-items: center;
+  padding: ${({ theme }) => theme.space[3]} ${({ theme }) => theme.space[4]};
+  background: ${({ theme, variant }) =>
+    variant === 'primary' ? theme.colors.primary : 'transparent'};
+  color: ${({ theme, variant }) =>
+    variant === 'primary' ? theme.colors.white : theme.colors.primary};
+`;
+
+export const Button = ({ variant, children }) => (
+  <StyledButton variant={variant}>{children}</StyledButton>
+);
+```
+
+### 3. Tailwind CSS
+
+```tsx
+import clsx from 'clsx';
+
+export const Button: React.FC<ButtonProps> = ({ variant, size, children }) => {
+  return (
+    <button
+      className={clsx(
+        'inline-flex items-center rounded-md font-medium',
+        {
+          'bg-blue-600 text-white hover:bg-blue-700': variant === 'primary',
+          'bg-transparent text-blue-600 border border-blue-600': variant === 'secondary',
+        },
+        {
+          'px-3 py-2 text-sm': size === 'sm',
+          'px-4 py-2 text-base': size === 'md',
+          'px-6 py-3 text-lg': size === 'lg',
+        }
+      )}
+    >
+      {children}
+    </button>
+  );
+};
+```

+    },
+  },
+};
+```
+
+## Testing Strategies
+
+### Unit Tests
+
+```tsx
+describe('Button', () => {
+  it('renders with correct variant', () => {
+    render(<Button variant="primary">Test</Button>);
+    expect(screen.getByRole('button')).toHaveClass('button--primary');
+  });
+
+  it('calls onClick when clicked', () => {
+    const handleClick = jest.fn();
+    render(<Button onClick={handleClick}>Test</Button>);
+
+    fireEvent.click(screen.getByRole('button'));
+    expect(handleClick).toHaveBeenCalledTimes(1);
+  });
+});
+```
+
+### Accessibility Tests
+
+```tsx
+import { axe, toHaveNoViolations } from 'jest-axe';
+
+expect.extend(toHaveNoViolations);
+
+it('has no accessibility violations', async () => {
+  const { container } = render(<Button>Test</Button>);
+  const results = await axe(container);
+  expect(results).toHaveNoViolations();
+});
+```
+
+### Visual Regression Tests
+
+```tsx
+// Using Chromatic or Percy
+it('matches snapshot', () => {
+  const { container } = render(<Button variant="primary">Test</Button>);
+  expect(container).toMatchSnapshot();
+});
+```
+
+## Performance Optimization
+
+### Code Splitting
+
+```tsx
+// Lazy load heavy components
+const HeavyComponent = lazy(() => import('./HeavyComponent'));
+
+export const App = () => (
+  <Suspense fallback={<LoadingSpinner />}>
+    <HeavyComponent />
+  </Suspense>
+);
+```
+
+### Memoization
+
+```tsx
+// Memoize expensive components
+export const ExpensiveComponent = memo(({ data }) => {
+  // Expensive rendering logic
+  return <div>{processData(data)}</div>;
+});
+
+// Memoize callbacks
+const handleClick = useCallback(() => {
+  // Handle click
+}, [dependencies]);
+
+// Memoize values
+const expensiveValue = useMemo(() => {
+  return computeExpensiveValue(data);
+}, [data]);
+```
+
+## Version Control
+
+### Semantic Versioning
+
+```

+
+1.0.0 → Initial release
+1.1.0 → New feature (backwards compatible)

+# Design Tokens Reference
+
+Complete guide to implementing and using design tokens in your design system.
+
+## What Are Design Tokens?
+
+Design tokens are the visual design atoms of your design system — specifically, they are named entities that store visual design attributes. They're used in place of hard-coded values to maintain a scalable and consistent visual system.
+
+## Benefits
+
+**Consistency**
+- Single source of truth for design values
+- Ensures brand consistency across platforms
+- Easy to maintain and update
+
+**Scalability**
+- Change values in one place, update everywhere
+- Support multiple themes (light/dark)
+- Platform-agnostic (web, iOS, Android)
+
+**Developer-Designer Communication**
+- Shared vocabulary between teams
+- Design decisions are codified
+- Reduces ambiguity
+
+## Token Categories
+
+### 1. Color Tokens
+
+```css
+:root {
+  /* Brand Colors */
+  --color-primary: #0066FF;
+  --color-primary-hover: #0052CC;
+  --color-primary-active: #003D99;
+  --color-primary-subtle: #E6F0FF;
+
+  --color-secondary: #6B7280;
+  --color-secondary-hover: #4B5563;
+
+  /* Semantic Colors */
+  --color-success: #10B981;
+  --color-warning: #F59E0B;
+  --color-error: #EF4444;
+  --color-info: #3B82F6;
+
+  /* Neutral Palette */
+  --color-white: #FFFFFF;
+  --color-black: #000000;
+  --color-gray-50: #F9FAFB;
+  --color-gray-100: #F3F4F6;
+  /* ... through gray-900 */
+
+  /* Surface Colors */
+  --color-surface: var(--color-white);
+  --color-background: var(--color-white);
+
+  /* Text Colors */
+  --color-text: var(--color-gray-900);
+  --color-text-secondary: var(--color-gray-600);
+  --color-text-tertiary: var(--color-gray-400);
+
+  /* Border Colors */
+  --color-border: var(--color-gray-200);
+  --color-border-hover: var(--color-gray-300);
+
+  /* Focus */
+  --color-focus: var(--color-primary);
+}
+```
+
+**Naming Convention:**
+```
+--color-{category}-{variant}-{state}
+
+Examples:
+--color-primary              (base brand color)
+--color-primary-hover        (interactive state)
+--color-success-subtle       (background usage)
+--color-text-secondary       (content hierarchy)
+```

+
+## Semantic vs Reference Tokens
+
+### Reference Tokens (Raw Values)
+```css
+:root {
+  --blue-500: #0066FF;
+  --gray-100: #F3F4F6;
+  --spacing-4: 1rem;
+}
+```
+
+### Semantic Tokens (Meaningful Names)
+```css
+:root {
+  --color-primary: var(--blue-500);
+  --color-surface: var(--gray-100);
+  --button-padding: var(--spacing-4);
+}
+```
+
+**Always use semantic tokens in components:**
+```css
+/* ❌ Don't */
+.button {
+  background: var(--blue-500);
+  padding: var(--spacing-4);
+}
+
+/* ✅ Do */
+.button {
+  background: var(--color-primary);
+  padding: var(--button-padding);
+}
+```
+
+## Theming with Tokens
+
+### Light/Dark Mode
+
+```css
+:root {
+  /* Light theme (default) */
+  --color-surface: #FFFFFF;
+  --color-text: #111827;
+  --color-border: #E5E7EB;
+}
+
+@media (prefers-color-scheme: dark) {
+  :root {
+    --color-surface: #1F2937;
+    --color-text: #F9FAFB;
+    --color-border: #4B5563;
+  }
+}
+
+/* Or class-based theming */
+[data-theme="dark"] {
+  --color-surface: #1F2937;
+  --color-text: #F9FAFB;
+  --color-border: #4B5563;
+}
+```
+
+### Brand Theming
+
+```css
+:root {
+  --color-primary: var(--brand-blue);
+}
+
+[data-brand="tech"] {
+  --brand-blue: #0066FF;
+}
+
+[data-brand="health"] {
+  --brand-blue: #10B981;
+}
+
+[data-brand="finance"] {
+  --brand-blue: #6366F1;
+}
+```
+
+## Component-Specific Tokens
+
+```css
+:root {
+  /* Button */
+  --button-padding-sm: var(--space-2) var(--space-3);
+  --button-padding-md: var(--space-3) var(--space-4);
+  --button-padding-lg: var(--space-4) var(--space-6);
+  --button-radius: var(--radius-md);
+  --button-font-weight: var(--font-medium);
+
+  /* Input */
+  --input-height-sm: 36px;
+  --input-height-md: 44px;
+  --input-height-lg: 52px;
+  --input-border-color: var(--color-border);
+  --input-focus-color: var(--color-primary);
+
+  /* Card */
+  --card-padding: var(--space-6);
+  --card-radius: var(--radius-lg);
+  --card-shadow: var(--shadow-md);
+}
+```
+
+## Platform-Specific Tokens
+
+### CSS Custom Properties (Web)
+```css
+:root {
+  --color-primary: #0066FF;
+}
+
+.button {
+  background: var(--color-primary);
+}
+```
+
+### JSON (React Native, iOS, Android)
+```json
+{
+  "color": {
+    "primary": "#0066FF",
+    "surface": "#FFFFFF",
+    "text": "#111827"
+  },
+  "spacing": {
+    "4": 16,
+    "6": 24,
+    "8": 32
+  }
+}
+```
+
+### JavaScript/TypeScript
+```typescript
+export const tokens = {
+  color: {
+    primary: '#0066FF',
+    surface: '#FFFFFF',
+    text: '#111827',
+  },
+  spacing: {
+    4: '1rem',
+    6: '1.5rem',
+    8: '2rem',
+  },
+} as const;
+
+// Usage
+const Button = styled.button`
+  background: ${tokens.color.primary};
+  padding: ${tokens.spacing.4};
+`;
+```
+
+## Best Practices
+
+### Naming Conventions
+
+**Do:**
+- Use descriptive, semantic names
+- Follow consistent patterns
+- Group related tokens
+
+```css
+/* ✅ Good */
+--color-primary
+--color-primary-hover
+--color-primary-subtle
+--button-padding-md
+--shadow-card
+```
+
+**Don't:**
+- Use arbitrary or cryptic names
+- Mix naming conventions
+- Use values in names
+
+```css
+/* ❌ Bad */
+--blue
+--primary-color-hover-state
+--padding16px
+--btn-pad
+```
+
+### Organization
+
+Group tokens by category:
+```
+tokens/
+├── colors.css
+├── typography.css
+├── spacing.css
+├── shadows.css
+├── borders.css
+├── zindex.css
+└── index.css (imports all)
+```
+
+### Documentation
+
+Document token usage:
+```css
+/**
+ * Primary brand color
+ * Used for: primary buttons, links, focus states
+ * Contrast ratio: 4.6:1 (WCAG AA compliant)
+ */
+--color-primary: #0066FF;
+```
+
+### Accessibility
+
+Ensure proper contrast:
+```css
+:root {
+  --color-primary: #0066FF;
+  --color-text-on-primary: #FFFFFF;
+  /* Contrast ratio: 4.5:1 ✅ */
+}
+```
+
+### Performance
+
+Use CSS variables efficiently:
+```css
+/* ✅ Define once, use everywhere */
+:root {
+  --color-primary: #0066FF;
+}
+
+/* ❌ Don't redefine in every selector */
+.button { --color-primary: #0066FF; }
+.link { --color-primary: #0066FF; }
+```
+
+## Migration Strategy
+
+### Step 1: Audit Current Values
+```bash
+# Find all color values
+grep -r "#[0-9A-Fa-f]\{6\}" src/
+
+# Find all spacing values
+grep -r "padding:\|margin:" src/
+```
+
+### Step 2: Create Token Definitions
+```css
+:root {
+  /* Extract unique values */
+  --color-primary: #0066FF;
+  --space-4: 1rem;
+}
+```
+
+### Step 3: Replace Hard-Coded Values
+```css
+/* Before */
+.button {
+  background: #0066FF;
+  padding: 1rem;
+}
+
+/* After */
+.button {
+  background: var(--color-primary);
+  padding: var(--space-4);
+}
+```
+
+### Step 4: Test & Validate
+- Visual regression testing
+- Accessibility testing
+- Cross-browser testing
+- Dark mode verification
+
+## Tools
+
+**Design Token Tools:**
+- Style Dictionary (transforms tokens to multiple formats)
+- Theo (Salesforce's token transformer)
+- Design Tokens CLI
+
+**Browser DevTools:**
+- Chrome: Inspect computed custom properties
+- Firefox: CSS Variables viewer
+
+**Example Script:**
+```javascript
+// Extract all CSS custom properties
+const properties = Array.from(document.styleSheets)
+  .flatMap(sheet => Array.from(sheet.cssRules))
+  .filter(rule => rule.style)
+  .flatMap(rule => Array.from(rule.style))
+  .filter(prop => prop.startsWith('--'));
+
+console.log([...new Set(properties)]);
+```

+# Responsive Design Patterns
+
+Modern responsive design patterns and techniques for creating flexible, accessible layouts that work across all devices.
+
+## Mobile-First Approach
+
+Start with mobile design and enhance for larger screens.
+
+### Why Mobile-First?
+
+**Benefits:**
+- Forces focus on essential content
+- Better performance (smaller base CSS)
+- Progressive enhancement mindset
+- Easier to add features than remove them
+
+**Basic Pattern:**
+```css
+/* Base (mobile) styles - no media query */
+.container {
+  width: 100%;
+  padding: 1rem;
+}
+
+/* Tablet and up */
+@media (min-width: 768px) {
+  .container {
+    padding: 2rem;
+  }
+}
+
+/* Desktop and up */
+@media (min-width: 1024px) {
+  .container {
+    max-width: 1200px;
+    margin: 0 auto;
+    padding: 3rem;
+  }
+}
+```
+
+## Breakpoints
+
+### Standard Breakpoints
+
+```css
+:root {
+  /* Mobile first - these are MIN widths */
+  --breakpoint-sm: 640px;   /* Small tablets, large phones */
+  --breakpoint-md: 768px;   /* Tablets */
+  --breakpoint-lg: 1024px;  /* Laptops, desktops */
+  --breakpoint-xl: 1280px;  /* Large desktops */
+  --breakpoint-2xl: 1536px; /* Extra large screens */
+}
+
+/* Usage */
+@media (min-width: 768px) {
+  /* Tablet and up */
+}
+
+@media (min-width: 1024px) {
+  /* Desktop and up */
+}
+```
+
+### Custom Breakpoints
+
+```css
+/* Content-based breakpoints */
+@media (min-width: 400px) {
+  /* When content needs it, not arbitrary device size */
+}
+
+/* Prefer rem-based breakpoints for accessibility */
+@media (min-width: 48rem) { /* 768px at 16px base */
+  /* Scales with user's font size preferences */
+}
+```
+
+### Container Queries (Modern)
+
+```css
+/* Respond to container size, not viewport */
+.card-container {
+  container-type: inline-size;
+  container-name: card;
+}
+
+@container card (min-width: 400px) {
+  .card {
+    display: grid;
+    grid-template-columns: 200px 1fr;
+  }
+}
+```

+```css
+/* Scales smoothly between min and max */
+h1 {
+  font-size: clamp(2rem, 5vw + 1rem, 4rem);
+  /* Min: 2rem (32px) */
+  /* Preferred: 5vw + 1rem */
+  /* Max: 4rem (64px) */
+}
+
+/* More examples */
+.text-sm {
+  font-size: clamp(0.875rem, 0.85rem + 0.125vw, 1rem);
+}
+
+.text-base {
+  font-size: clamp(1rem, 0.95rem + 0.25vw, 1.125rem);
+}
+
+.text-lg {
+  font-size: clamp(1.125rem, 1.05rem + 0.375vw, 1.25rem);
+}
+```
+
+### Responsive Line Height
+
+```css
+body {
+  /* Tighter on mobile, looser on desktop */
+  line-height: 1.5;
+}
+
+@media (min-width: 768px) {
+  body {
+    line-height: 1.6;
+  }
+}
+```
+
+## Layout Patterns
+
+### 1. Stack Layout
+
+**Everything stacks vertically on mobile, side-by-side on larger screens.**
+
+```css
+.stack {
+  display: flex;
+  flex-direction: column;
+  gap: 1rem;
+}
+
+@media (min-width: 768px) {
+  .stack {
+    flex-direction: row;
+  }
+}
+```
+
+### 2. Sidebar Layout
+
+**Sidebar stacks on mobile, side-by-side on desktop.**
+
+```css
+.sidebar-layout {
+  display: grid;
+  gap: 2rem;
+}
+
+@media (min-width: 768px) {
+  .sidebar-layout {
+    grid-template-columns: 250px 1fr;
+  }
+}
+
+/* Flexible sidebar */
+@media (min-width: 768px) {
+  .sidebar-layout--flexible {
+    grid-template-columns: minmax(200px, 300px) 1fr;
+  }
+}
+```
+
+### 3. Grid Layout
+
+**Responsive column count.**
+
+```css
+.grid {
+  display: grid;
+  gap: 1rem;
+
+  /* Mobile: 1 column */
+  grid-template-columns: 1fr;
+}
+
+@media (min-width: 640px) {
+  .grid {
+    /* Tablet: 2 columns */
+    grid-template-columns: repeat(2, 1fr);
+  }
+}
+
+@media (min-width: 1024px) {
+  .grid {
+    /* Desktop: 3-4 columns */
+    grid-template-columns: repeat(4, 1fr);
+  }
+}
+
+/* Auto-responsive grid (no media queries!) */
+.grid-auto {
+  display: grid;
+  gap: 1rem;
+  grid-template-columns: repeat(auto-fit, minmax(250px, 1fr));
+  /* Creates as many columns as fit, minimum 250px each */
+}
+```
+
+### 4. Holy Grail Layout
+
+**Classic three-column layout that adapts to mobile.**
+
+```css
+.holy-grail {
+  display: grid;
+  gap: 1rem;
+  min-height: 100vh;
+
+  /* Mobile: stack everything */
+  grid-template:
+    "header" auto
+    "main" 1fr
+    "sidebar1" auto
+    "sidebar2" auto
+    "footer" auto
+    / 1fr;
+}
+
+@media (min-width: 768px) {
+  .holy-grail {
+    /* Desktop: traditional layout */
+    grid-template:
+      "header header header" auto
+      "sidebar1 main sidebar2" 1fr
+      "footer footer footer" auto
+      / 200px 1fr 200px;
+  }
+}
+
+.header { grid-area: header; }
+.sidebar-1 { grid-area: sidebar1; }
+.main { grid-area: main; }
+.sidebar-2 { grid-area: sidebar2; }
+.footer { grid-area: footer; }
+```
+
+### 5. Card Layout
+
+**Responsive cards that adapt their internal layout.**
+
+```css
+.card {
+  display: grid;
+  gap: 1rem;
+
+  /* Mobile: stack image and content */
+  grid-template:
+    "image" auto
+    "content" 1fr
+    / 1fr;
+}
+
+@media (min-width: 640px) {
+  .card {
+    /* Tablet+: side-by-side */
+    grid-template:
+      "image content" 1fr
+      / 200px 1fr;
+  }
+}
+
+.card__image { grid-area: image; }
+.card__content { grid-area: content; }
+```
+
+### 6. Switcher Pattern
+
+**Switch between horizontal and vertical based on available space.**
+
+```css
+.switcher {
+  display: flex;
+  flex-wrap: wrap;
+  gap: 1rem;
+}
+
+.switcher > * {
+  /* Grow to fill, but switch to vertical when < 400px */
+  flex-grow: 1;
+  flex-basis: calc((400px - 100%) * 999);
+  /* Clever calc that breaks at threshold */
+}
+```
+
+### 7. Pancake Stack
+
+**Header, main, footer layout that adapts height.**
+
+```css
+.pancake {
+  display: grid;
+  grid-template-rows: auto 1fr auto;
+  min-height: 100vh;
+}
+
+.header { /* auto height */ }
+.main { /* fills available space */ }
+.footer { /* auto height */ }
+```
+
+## Responsive Images
+
+### 1. Flexible Images
+
+```css
+img {
+  max-width: 100%;
+  height: auto;
+  display: block;
+}
+```
+
+### 2. Art Direction (Different Images per Breakpoint)
+
+```html
+<picture>
+  <source media="(min-width: 1024px)" srcset="large.jpg">
+  <source media="(min-width: 768px)" srcset="medium.jpg">
+  <img src="small.jpg" alt="Description">
+</picture>
+```
+
+### 3. Resolution Switching (Same Image, Different Sizes)
+
+```html
+<img
+  srcset="
+    small.jpg 400w,
+    medium.jpg 800w,
+    large.jpg 1200w
+  "
+  sizes="
+    (min-width: 1024px) 800px,
+    (min-width: 768px) 600px,
+    100vw
+  "
+  src="medium.jpg"
+  alt="Description"
+>
+```
+
+### 4. Background Images
+
+```css
+.hero {
+  background-image: url('small.jpg');
+  background-size: cover;
+  background-position: center;
+}
+
+@media (min-width: 768px) {
+  .hero {
+    background-image: url('medium.jpg');
+  }
+}
+
+@media (min-width: 1024px) {
+  .hero {
+    background-image: url('large.jpg');
+  }
+}
+
+@media (min-width: 1024px) and (-webkit-min-device-pixel-ratio: 2) {
+  .hero {
+    background-image: url('large@2x.jpg');
+  }
+}
+```
+
+### 5. Aspect Ratio
+
+```css
+/* Modern aspect ratio */
+.image-container {
+  aspect-ratio: 16 / 9;
+  overflow: hidden;
+}
+
+.image-container img {
+  width: 100%;
+  height: 100%;
+  object-fit: cover;
+}
+
+/* Fallback for older browsers */
+.image-container-fallback {
+  position: relative;
+  padding-bottom: 56.25%; /* 16:9 aspect ratio */
+}
+
+.image-container-fallback img {
+  position: absolute;
+  top: 0;
+  left: 0;
+  width: 100%;
+  height: 100%;
+  object-fit: cover;
+}
+```
+
+## Responsive Navigation
+
+### 1. Mobile Menu (Hamburger)
+
+```html
+<nav class="nav">
+  <div class="nav__brand">Logo</div>
+
+  <button class="nav__toggle" aria-expanded="false" aria-controls="nav-menu">
+    <span class="sr-only">Menu</span>
+    <span class="hamburger"></span>
+  </button>
+
+  <ul class="nav__menu" id="nav-menu">
+    <li><a href="/">Home</a></li>
+    <li><a href="/about">About</a></li>
+    <li><a href="/contact">Contact</a></li>
+  </ul>
+</nav>
+```
+
+```css
+.nav {
+  display: flex;
+  justify-content: space-between;
+  align-items: center;
+  padding: 1rem;
+}
+
+/* Mobile: hidden menu */
+.nav__menu {
+  display: none;
+  position: absolute;
+  top: 100%;
+  left: 0;
+  right: 0;
+  background: white;
+  flex-direction: column;
+  padding: 1rem;
+}
+
+.nav__menu[aria-expanded="true"] {
+  display: flex;
+}
+
+.nav__toggle {
+  display: block;
+}
+
+/* Desktop: visible menu */
+@media (min-width: 768px) {
+  .nav__menu {
+    display: flex;
+    position: static;
+    flex-direction: row;
+    gap: 2rem;
+  }
+
+  .nav__toggle {
+    display: none;
+  }
+}
+```
+
+### 2. Priority+ Navigation
+
+**Show important items, collapse others into "More" menu.**
+
+```css
+.priority-nav {
+  display: flex;
+  gap: 1rem;
+}
+
+.priority-nav__item {
+  flex-shrink: 0; /* Don't shrink */
+}
+
+.priority-nav__more {
+  margin-left: auto; /* Push to end */
+}
+
+/* Hide items that don't fit */
+@media (max-width: 768px) {
+  .priority-nav__item:nth-child(n+4) {
+    display: none; /* Hide items 4+ */
+  }
+}
+```
+
+## Responsive Tables
+
+### 1. Horizontal Scroll
+
+```css
+.table-container {
+  overflow-x: auto;
+  -webkit-overflow-scrolling: touch; /* Smooth scrolling on iOS */
+}
+
+table {
+  min-width: 600px;
+  width: 100%;
+}
+```
+
+### 2. Stacked Table (Card View)
+
+```html
+<table class="responsive-table">
+  <thead>
+    <tr>
+      <th>Name</th>
+      <th>Email</th>
+      <th>Role</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td data-label="Name">John Doe</td>
+      <td data-label="Email">john@example.com</td>
+      <td data-label="Role">Developer</td>
+    </tr>
+  </tbody>
+</table>
+```
+
+```css
+/* Desktop: normal table */
+@media (min-width: 768px) {
+  .responsive-table {
+    display: table;
+  }
+}
+
+/* Mobile: stacked cards */
+@media (max-width: 767px) {
+  .responsive-table,
+  .responsive-table thead,
+  .responsive-table tbody,
+  .responsive-table tr,
+  .responsive-table th,
+  .responsive-table td {
+    display: block;
+  }
+
+  .responsive-table thead {
+    display: none; /* Hide table header */
+  }
+
+  .responsive-table tr {
+    margin-bottom: 1rem;
+    border: 1px solid #ddd;
+    border-radius: 0.5rem;
+    padding: 1rem;
+  }
+
+  .responsive-table td {
+    display: flex;
+    justify-content: space-between;
+    padding: 0.5rem 0;
+    border-bottom: 1px solid #eee;
+  }
+
+  .responsive-table td:last-child {
+    border-bottom: none;
+  }
+
+  .responsive-table td::before {
+    content: attr(data-label);
+    font-weight: bold;
+    margin-right: 1rem;
+  }
+}
+```
+
+## Responsive Forms
+
+### 1. Single Column to Multi-Column
+
+```css
+.form {
+  display: grid;
+  gap: 1rem;
+
+  /* Mobile: single column */
+  grid-template-columns: 1fr;
+}
+
+@media (min-width: 768px) {
+  .form {
+    /* Desktop: two columns */
+    grid-template-columns: repeat(2, 1fr);
+  }
+
+  .form__field--full {
+    /* Some fields span both columns */
+    grid-column: 1 / -1;
+  }
+}
+```
+
+### 2. Touch-Friendly Inputs
+
+```css
+input,
+button,
+select,
+textarea {
+  /* Minimum 44x44px touch target */
+  min-height: 44px;
+  padding: 0.75rem 1rem;
+  font-size: 1rem; /* Prevents zoom on iOS */
+}
+
+@media (min-width: 768px) {
+  input,
+  button,
+  select,
+  textarea {
+    /* Can be smaller on desktop */
+    min-height: 40px;
+    font-size: 0.875rem;
+  }
+}
+```
+
+## Responsive Utilities
+
+### Show/Hide at Breakpoints
+
+```css
+/* Hide on mobile */
+.hidden-mobile {
+  display: none;
+}
+
+@media (min-width: 768px) {
+  .hidden-mobile {
+    display: block;
+  }
+}
+
+/* Show only on mobile */
+.visible-mobile {
+  display: block;
+}
+
+@media (min-width: 768px) {
+  .visible-mobile {
+    display: none;
+  }
+}
+
+/* Hide on desktop */
+@media (min-width: 1024px) {
+  .hidden-desktop {
+    display: none;
+  }
+}
+```
+
+### Responsive Spacing
+
+```css
+.section {
+  /* Mobile: smaller padding */
+  padding: 2rem 1rem;
+}
+
+@media (min-width: 768px) {
+  .section {
+    /* Tablet: medium padding */
+    padding: 4rem 2rem;
+  }
+}
+
+@media (min-width: 1024px) {
+  .section {
+    /* Desktop: larger padding */
+    padding: 6rem 3rem;
+  }
+}
+
+/* Or use fluid spacing */
+.section-fluid {
+  padding: clamp(2rem, 5vw, 6rem) clamp(1rem, 3vw, 3rem);
+}
+```
+
+## Testing Responsive Design
+
+### Browser DevTools
+
+```javascript
+// Common viewport sizes to test
+const viewports = [
+  { width: 375, height: 667, name: 'iPhone SE' },
+  { width: 390, height: 844, name: 'iPhone 12 Pro' },
+  { width: 428, height: 926, name: 'iPhone 14 Pro Max' },
+  { width: 768, height: 1024, name: 'iPad' },
+  { width: 1024, height: 768, name: 'iPad Landscape' },
+  { width: 1280, height: 720, name: 'Desktop' },
+  { width: 1920, height: 1080, name: 'Full HD' },
+];
+```
+
+### Responsive Testing Checklist
+
+- [ ] Test all breakpoints
+- [ ] Test between breakpoints (awkward sizes)
+- [ ] Test portrait and landscape
+- [ ] Test zoom levels (100%, 200%, 400%)
+- [ ] Test with real devices when possible
+- [ ] Test touch interactions on mobile
+- [ ] Test with different font sizes
+- [ ] Test with slow network (images, fonts)
+
+## Performance Considerations
+
+### Lazy Loading
+
+```html
+<!-- Lazy load images below the fold -->
+<img src="image.jpg" loading="lazy" alt="Description">
+
+<!-- Eager load above-the-fold images -->
+<img src="hero.jpg" loading="eager" alt="Hero image">
+```
+
+### Conditional Loading
+
+```javascript
+// Load component only on larger screens
+if (window.matchMedia('(min-width: 768px)').matches) {
+  import('./DesktopComponent.js').then(module => {
+    // Initialize desktop component
+  });
+}
+```
+
+### Font Loading
+
+```css
+@font-face {
+  font-family: 'CustomFont';
+  src: url('font.woff2') format('woff2');
+  font-display: swap; /* Show fallback while loading */
+}
+```
+
+## Modern CSS Features
+
+### 1. CSS Grid Auto-Fill
+
+```css
+.grid {
+  display: grid;
+  gap: 1rem;
+  grid-template-columns: repeat(auto-fill, minmax(250px, 1fr));
+  /* Automatically creates columns, minimum 250px */
+}
+```
+
+### 2. Flexbox Gap
+
+```css
+.flex-container {
+  display: flex;
+  flex-wrap: wrap;
+  gap: 1rem; /* No more margin hacks! */
+}
+```
+
+### 3. Container Queries
+
+```css
+.card {
+  container-type: inline-size;
+}
+
+@container (min-width: 400px) {
+  .card__title {
+    font-size: 1.5rem;
+  }
+}
+```
+
+### 4. Aspect Ratio
+
+```css
+.video-container {
+  aspect-ratio: 16 / 9;
+}
+```
+
+### 5. Logical Properties
+
+```css
+/* Better for RTL/LTR support */
+.element {
+  margin-block-start: 1rem; /* margin-top */
+  margin-block-end: 1rem; /* margin-bottom */
+  margin-inline-start: 1rem; /* margin-left in LTR, margin-right in RTL */
+  margin-inline-end: 1rem; /* margin-right in LTR, margin-left in RTL */
+}
+```

+description: Manage Git worktrees for parallel Claude Code development. Use this skill when engineers ask to "create a worktree", "run parallel Claude sessions", "work on multiple features simultaneously", or need help with worktree management.
+---
+
+# Git Worktrees for Claude Code
+
+## Overview
+
+Run multiple Claude Code sessions in parallel on different branches using Git worktrees. This skill provides simple scripts and workflows to set up, manage, and clean up worktrees, enabling true parallel development without conflicts.
+
+**Why Worktrees?**
+- **Parallel Development**: Run multiple Claude Code instances simultaneously
+- **Zero Conflicts**: Each worktree has independent file state
+- **Fast Context Switching**: No need to stash/commit when switching tasks
+- **Isolated Experiments**: Try different approaches without affecting main work
+- **Long-Running Tasks**: Let Claude work in background while you continue in main
+
+---
+
+## Quick Start
+
+### 1. Create a New Worktree (Super Easy!)
+
+Just run the interactive script:
+
+```bash
+scripts/create_worktree.sh
+```
+
+This will:
+- ✅ Prompt for feature name
+- ✅ Create a new branch
+- ✅ Set up the worktree
+- ✅ Open in VS Code / editor
+- ✅ Give you the Claude Code setup command
+
+**That's it!** The script handles all complexity.
+
+---
+
+### 2. View All Worktrees
+
+```bash
+scripts/list_worktrees.sh
+```
+
+Shows a clean, formatted list of all your worktrees with their branches and status.
+
+---
+
+### 3. Clean Up Old Worktrees
+
+```bash
+scripts/cleanup_worktrees.sh
+```
+
+Interactive removal of merged or abandoned worktrees.
+
+---
+
+## Core Workflow
+
+### Pattern 1: Parallel Feature Development
+
+**Scenario:** You want Claude to build feature A while you work on feature B.
+
+**Steps:**
+
+1. **Create worktree for feature A:**
+   ```bash
+   scripts/create_worktree.sh
+   # Enter: feature-a
+   # Script creates: ../repo-feature-a/
+   ```
+
+2. **Open Claude Code in the new worktree:**
+   - The script outputs the path
+   - Open Claude Code and navigate to that directory
+   - Run `/init` to orient Claude
+
+3. **Give Claude the task:**
+   ```
+   "Build the user authentication feature with OAuth support"
+   ```
+
+4. **Continue your work in main:**
+   - Your original directory is unchanged
+   - No conflicts, no waiting
+   - Claude works in parallel
+
+5. **When both are done, merge:**
+   ```bash
+   # Review Claude's work
+   cd ../repo-feature-a
+   git log
+
+   # If good, merge back
+   git checkout main
+   git merge feature-a
+
+   # Clean up
+   scripts/cleanup_worktrees.sh
+   ```
+
+---
+
+### Pattern 2: Long-Running Refactor
+
+**Scenario:** You want Claude to refactor a large module while you continue development.
+
+**Steps:**
+
+1. **Create refactor worktree:**
+   ```bash
+   scripts/create_worktree.sh
+   # Enter: refactor-auth-module
+   ```
+
+2. **Start Claude in refactor worktree:**
+   ```
+   "Refactor the authentication module to use dependency injection"
+   ```
+
+3. **Continue your daily work in main:**
+   - No interruption
+   - No merge conflicts
+   - Check progress periodically
+
+4. **Review and integrate when ready:**
+   ```bash
+   cd ../repo-refactor-auth-module
+   git log --oneline
+   # Review changes
+
+   # Merge when satisfied
+   git checkout main
+   git merge refactor-auth-module
+   ```
+
+---
+
+### Pattern 3: Multiple AI Agents (Advanced)
+
+**Scenario:** You want 3 Claude instances working on different features simultaneously.
+
+**Steps:**
+
+1. **Create 3 worktrees:**
+   ```bash
+   scripts/create_worktree.sh  # feature-api-endpoints
+   scripts/create_worktree.sh  # feature-ui-dashboard
+   scripts/create_worktree.sh  # feature-email-notifications
+   ```
+
+2. **Open 3 Claude Code sessions:**
+   - Session 1: `../repo-feature-api-endpoints/`
+   - Session 2: `../repo-feature-ui-dashboard/`
+   - Session 3: `../repo-feature-email-notifications/`
+
+3. **Assign tasks to each Claude:**
+   - Claude 1: "Build REST API endpoints for user management"
+   - Claude 2: "Create admin dashboard UI"
+   - Claude 3: "Implement email notification system"
+
+4. **Monitor progress:**
+   ```bash
+   scripts/list_worktrees.sh
+   ```
+
+5. **Merge features as they complete:**
+   ```bash
+   # Feature by feature
+   git checkout main
+   git merge feature-api-endpoints
+   git merge feature-ui-dashboard
+   git merge feature-email-notifications
+
+   # Clean up
+   scripts/cleanup_worktrees.sh
+   ```
+
+---
+
+### Pattern 4: Hotfix While Development Continues
+
+**Scenario:** Production bug needs immediate fix while Claude is working on a feature.
+
+**Steps:**
+
+1. **Claude is already working in a feature worktree**
+   - Let it continue, don't interrupt
+
+2. **Create hotfix worktree from main:**
+   ```bash
+   scripts/create_worktree.sh
+   # Enter: hotfix-login-bug
+   # Choose base branch: main
+   ```
+
+3. **Fix the bug yourself or with another Claude session:**
+   ```bash
+   cd ../repo-hotfix-login-bug
+   # Make fixes
+   git add .
+   git commit -m "Fix login redirect bug"
+   ```
+
+4. **Merge hotfix to main:**
+   ```bash
+   git checkout main
+   git merge hotfix-login-bug
+   git push origin main
+   ```
+
+5. **Sync feature worktree with latest main:**
+   ```bash
+   cd ../repo-feature-xyz
+   scripts/sync_worktree.sh
+   # Merges latest main into feature branch
+   ```
+
+---
+
+## Essential Scripts
+
+### scripts/create_worktree.sh
+
+**Interactive worktree creation with all the right defaults.**
+
+**What it does:**
+1. Prompts for feature name
+2. Validates git repo
+3. Creates branch from main (or specified base)
+4. Sets up worktree in parallel directory
+5. Outputs setup instructions
+
+**Usage:**
+```bash
+scripts/create_worktree.sh
+
+# Prompts:
+# Feature name: my-feature
+# Base branch (default: main):
+#
+# Creates: ../repo-my-feature/
+# Branch: my-feature
+```
+
+**Advanced usage:**
+```bash
+# Create from specific branch
+scripts/create_worktree.sh --base develop
+
+# Specify location
+scripts/create_worktree.sh --dir ~/worktrees/my-feature
+```
+
+---
+
+### scripts/list_worktrees.sh
+
+**Shows all active worktrees with status.**
+
+**Output:**
+```
+╔════════════════════════════════════════════════╗
+║            Active Git Worktrees                ║
+╚════════════════════════════════════════════════╝
+
+📁 Main Worktree
+   Path: /home/user/project
+   Branch: main
+   Status: clean
+
+📁 Feature Worktrees
+   Path: /home/user/project-feature-api
+   Branch: feature-api
+   Status: 2 uncommitted changes
+
+   Path: /home/user/project-refactor
+   Branch: refactor-auth
+   Status: clean
+```
+
+---
+
+### scripts/cleanup_worktrees.sh
+
+**Interactive cleanup of old worktrees.**
+
+**Features:**
+- Lists all worktrees with merge status
+- Identifies merged branches (safe to remove)
+- Prompts for confirmation
+- Safely removes worktree and branch
+
+**Usage:**
+```bash
+scripts/cleanup_worktrees.sh
+
+# Output:
+# Found 3 worktrees
+#
+# 1. feature-api (merged to main) - Safe to remove
+# 2. feature-dashboard (not merged) - Keep
+# 3. old-experiment (not merged, 30 days old) - Consider removing
+#
+# Which worktrees to remove? (1,3): 1
+```
+
+---
+
+### scripts/sync_worktree.sh
+
+**Keep worktree up-to-date with main branch.**
+
+**What it does:**
+1. Fetches latest from remote
+2. Merges main into current worktree branch
+3. Handles conflicts with guidance
+
+**Usage:**
+```bash
+# From within a worktree
+cd ../repo-feature-api
+scripts/sync_worktree.sh
+
+# Or specify worktree
+scripts/sync_worktree.sh ../repo-feature-api
+```
+
+---
+
+## Claude Code Integration
+
+### Important: Run /init in Each Worktree
+
+When you open a new Claude Code session in a worktree, **always run `/init` first**:
+
+```
+/init
+```
+
+This ensures Claude:
+- Understands the codebase structure
+- Has proper context
+- Can navigate files correctly
+
+### Recommended Claude Code Workflow
+
+1. **Create worktree** (using script)
+2. **Open Claude Code** in worktree directory
+3. **Run `/init`** to orient Claude
+4. **Give task** to Claude
+5. **Monitor** via `git log` or file watching
+6. **Review** when complete
+7. **Merge** if satisfied
+8. **Cleanup** worktree
+
+---
+
+## Best Practices
+
+### Naming Conventions
+
+**Good names:**
+- `feature-user-auth` ✅
+- `refactor-api-layer` ✅
+- `hotfix-login-bug` ✅
+- `experiment-new-db` ✅
+
+**Bad names:**
+- `test` ❌ (too vague)
+- `wt1` ❌ (meaningless)
+- `fixes` ❌ (unclear)
+
+**Recommended format:**
+```
+<type>-<short-description>
+
+Types:
+- feature-*
+- refactor-*
+- hotfix-*
+- experiment-*
+- review-*
+```
+
+---
+
+### Directory Structure
+
+**Recommended layout:**
+```
+~/projects/
+  └── myapp/              # Main worktree (main branch)
+      ├── myapp-feature-api/      # Feature worktree
+      ├── myapp-refactor-auth/    # Refactor worktree
+      └── myapp-hotfix-bug/       # Hotfix worktree
+```
+
+The scripts default to creating worktrees as siblings to your main directory with a naming pattern: `<repo>-<branch-name>`.
+
+---
+
+### When to Use Worktrees
+
+**✅ Use worktrees when:**
+- Running multiple Claude Code sessions in parallel
+- Working on independent features simultaneously
+- Doing long-running refactors
+- Experimenting with major changes
+- Quick hotfixes during feature development
+- Code reviews without interrupting work
+
+**❌ Don't use worktrees for:**
+- Simple branch switching (just use `git checkout`)
+- Minor tweaks (stash instead)
+- Single-task workflows
+- Very short-lived branches (< 1 hour)
+
+---
+
+### Keeping Worktrees in Sync
+
+**Problem:** Feature branches can get out of date with main.
+
+**Solution:** Regularly sync worktrees:
+
+```bash
+# Option 1: Use the sync script
+cd ../repo-feature-api
+scripts/sync_worktree.sh
+
+# Option 2: Manual sync
+cd ../repo-feature-api
+git fetch origin
+git merge origin/main
+```
+
+**Recommended frequency:**
+- Daily for long-running features
+- After major merges to main
+- Before creating PRs
+
+---
+
+### Managing Many Worktrees
+
+**Quick status of all worktrees:**
+```bash
+scripts/list_worktrees.sh
+```
+
+**Regular cleanup (weekly):**
+```bash
+scripts/cleanup_worktrees.sh
+```
+
+**Find stale worktrees:**
+```bash
+# Worktrees with old commits
+git worktree list | while read path branch commit; do
+  cd "$path"
+  last_commit=$(git log -1 --format=%cr)
+  echo "$branch: Last commit $last_commit"
+done
+```
+
+---
+
+## Troubleshooting
+
+### Issue: "fatal: invalid reference"
+
+**Cause:** Branch name has invalid characters
+
+**Solution:** Use alphanumeric + hyphens only:
+```bash
+# Bad
+feature/my_feature  ❌
+
+# Good
+feature-my-feature  ✅
+```
+
+---
+
+### Issue: "cannot remove worktree, path is not a working tree"
+
+**Cause:** Worktree directory was manually deleted
+
+**Solution:** Prune worktree references:
+```bash
+git worktree prune
+```
+
+---
+
+### Issue: Claude seems "lost" in worktree
+
+**Cause:** Didn't run `/init` after opening worktree
+
+**Solution:** Always run `/init` when starting Claude in a new worktree:
+```
+/init
+```
+
+---
+
+### Issue: Merge conflicts when syncing worktree
+
+**Cause:** Changes in worktree conflict with main
+
+**Solution 1:** Resolve conflicts manually:
+```bash
+cd ../repo-feature-api
+git fetch origin
+git merge origin/main
+# Fix conflicts in editor
+git add .
+git commit -m "Merge main and resolve conflicts"
+```
+
+**Solution 2:** If you want to discard worktree changes and restart:
+```bash
+cd ../repo-feature-api
+git fetch origin
+git reset --hard origin/main
+# Start feature over
+```
+
+---
+
+### Issue: "Cannot lock ref" error
+
+**Cause:** Branch exists in multiple worktrees
+
+**Solution:** You can't have the same branch checked out in multiple worktrees. Create a new branch:
+```bash
+scripts/create_worktree.sh
+# Use a different branch name
+```
+
+---
+
+### Issue: Worktree takes up too much disk space
+
+**Cause:** Git worktrees share the `.git` directory, but files are duplicated
+
+**Solution 1:** Clean up old worktrees:
+```bash
+scripts/cleanup_worktrees.sh
+```
+
+**Solution 2:** For large repos, use sparse-checkout:
+```bash
+git -C ../repo-feature-api sparse-checkout set src/ tests/
+```
+
+---
+
+## Advanced Usage
+
+### Custom Slash Command
+
+Create a `/worktree` command for Claude Code. See `references/slash_command_template.md` for the complete setup.
+
+**Usage after setup:**
+```
+/worktree feature-new-api
+```
+
+Claude will:
+1. Create the worktree
+2. Provide setup instructions
+3. Offer to continue the conversation in the new worktree
+
+---
+
+### Sharing Worktrees in Team
+
+**Worktrees are local only**, but you can share the workflow:
+
+1. **Share branch, not worktree:**
+   ```bash
+   cd ../repo-feature-api
+   git push origin feature-api
+
+   # Teammate creates their own worktree
+   git worktree add ../repo-feature-api feature-api
+   ```
+
+2. **Document your worktree structure** in team docs
+
+3. **Use consistent naming** across team
+
+---
+
+### Worktree Performance Optimization
+
+**For large repos:**
+
+1. **Use sparse-checkout** (only checkout files you need):
+   ```bash
+   git -C ../repo-feature-api sparse-checkout init
+   git -C ../repo-feature-api sparse-checkout set src/ tests/
+   ```
+
+2. **Use worktree prune regularly:**
+   ```bash
+   git worktree prune
+   ```
+
+3. **Limit concurrent worktrees** to 3-5 for best performance
+
+---
+
+## Common Workflows Summary

+| Create new worktree | `scripts/create_worktree.sh` |
+| List all worktrees | `scripts/list_worktrees.sh` |
+| Clean up worktrees | `scripts/cleanup_worktrees.sh` |
+| Sync with main | `scripts/sync_worktree.sh` |
+| Manual create | `git worktree add ../path branch-name` |
+| Manual list | `git worktree list` |
+| Manual remove | `git worktree remove ../path` |
+| Prune references | `git worktree prune` |
+
+---
+
+## Real-World Examples
+
+### Example 1: Parallel API & UI Development
+
+**Setup:**
+```bash
+# Create API worktree
+scripts/create_worktree.sh
+# Name: feature-api
+
+# Create UI worktree
+scripts/create_worktree.sh
+# Name: feature-ui
+```
+
+**Execution:**
+- Claude 1 in `../repo-feature-api`: "Build REST API for user management"
+- Claude 2 in `../repo-feature-ui`: "Create React UI for user management"
+- You in main: Continue other work
+
+**Merge:**
+```bash
+git checkout main
+git merge feature-api
+git merge feature-ui
+scripts/cleanup_worktrees.sh
+```
+
+---
+
+### Example 2: Code Review Without Context Switching
+
+**Scenario:** Need to review PR while Claude works on feature
+
+**Setup:**
+```bash
+# Claude is working in feature worktree
+# You need to review PR #123
+
+scripts/create_worktree.sh
+# Name: review-pr-123
+# Base: pr-branch-name
+```
+
+**Execution:**
+- Review code in `../repo-review-pr-123`
+- Claude continues work in `../repo-feature-xyz`
+- No context switching needed
+
+**Cleanup:**
+```bash
+# After review
+scripts/cleanup_worktrees.sh
+# Select review-pr-123
+```
+
+---
+
+### Example 3: Experimentation Without Risk
+
+**Scenario:** Want to try a radical refactor without breaking current work
+
+**Setup:**
+```bash
+scripts/create_worktree.sh
+# Name: experiment-new-architecture
+```
+
+**Execution:**
+- Experiment freely in `../repo-experiment-new-architecture`
+- Main worktree remains stable
+- If experiment fails, just delete worktree
+
+**Decision:**
+```bash
+# If experiment succeeded
+git checkout main
+git merge experiment-new-architecture
+
+# If experiment failed
+scripts/cleanup_worktrees.sh
+# Delete experiment worktree (no harm done)
+```
+
+---
+
+## Tips for Maximum Productivity
+
+### 1. **Name Worktrees Descriptively**
+   - You'll thank yourself later when you have 5 worktrees open
+
+### 2. **Always Run /init**
+   - First thing when opening Claude in a new worktree
+
+### 3. **Merge Frequently**
+   - Don't let worktrees diverge for weeks
+   - Sync with main regularly
+
+### 4. **Clean Up Weekly**
+   - Run `scripts/cleanup_worktrees.sh` every Friday
+   - Keep your workspace tidy
+
+### 5. **Use Scripts**
+   - Don't memorize git worktree commands
+   - Scripts handle edge cases and validation
+
+### 6. **Monitor Progress**
+   - Use `scripts/list_worktrees.sh` to see what's active
+   - Check git logs in worktrees periodically
+
+### 7. **Limit Concurrent Sessions**
+   - 3-5 worktrees max for best performance
+   - More than that gets hard to manage
+
+---
+
+## Resources

+
+## Naming Conventions
+
+### Branch Names
+
+**Use descriptive, hierarchical names:**
+
+```
+<type>-<short-description>
+
+Types:
+- feature-*     New features
+- refactor-*    Code refactoring
+- hotfix-*      Urgent bug fixes
+- experiment-*  Experimental changes
+- review-*      Code reviews
+- test-*        Testing branches
+```
+
+**Examples:**
+```bash
+✅ Good:
+- feature-user-authentication
+- refactor-api-layer
+- hotfix-login-redirect
+- experiment-new-db-schema
+- review-pr-123
+
+❌ Bad:
+- test
+- wt1
+- fixes
+- my-branch
+- abc
+```
+
+**Why it matters:**
+- Easy to identify purpose months later
+- Clear for team members
+- Searchable and filterable
+- Self-documenting
+
+---
+
+### Directory Names
+
+**Match branch names with prefix:**
+
+```bash
+# Pattern: <repo-name>-<branch-name>
+
+Example repository: myapp
+
+Worktrees:
+- myapp-feature-api
+- myapp-refactor-auth
+- myapp-hotfix-login
+```
+
+**Benefits:**
+- Immediately recognize which repo
+- See all worktrees with `ls ../`
+- Avoid confusion with multiple projects
+
+**Alternative patterns:**
+```bash
+# By date (for temporary worktrees)
+myapp-2025-01-15-hotfix
+
+# By ticket number
+myapp-JIRA-1234
+
+# By developer (in shared environments)
+myapp-john-feature-api
+```
+
+---
+
+## Directory Organization
+
+### Recommended Structure
+
+```
+~/projects/
+  └── myapp/                    # Main worktree (main branch)
+      ├── myapp-feature-api/    # Feature worktree
+      ├── myapp-feature-ui/     # Feature worktree
+      ├── myapp-refactor-auth/  # Refactor worktree
+      └── myapp-hotfix-login/   # Hotfix worktree
+```
+
+**Advantages:**
+- All related worktrees grouped together
+- Easy to find with `ls ../`
+- Clean navigation between worktrees
+
+---
+
+### Alternative: Dedicated Worktrees Directory
+
+```
+~/projects/
+  ├── myapp/                    # Main worktree
+  └── worktrees/
+      ├── myapp-feature-api/
+      ├── myapp-feature-ui/
+      └── myapp-refactor-auth/
+```
+
+**Use when:**
+- Working with many worktrees
+- Want clear separation
+- Sharing machine with others
+
+---
+
+### What NOT to Do
+
+```
+❌ Nested worktrees:
+~/projects/
+  └── myapp/
+      └── feature-api/  # Don't nest inside repo
+
+❌ Unrelated locations:
+~/projects/myapp/               # Main
+~/Documents/api-feature/        # Confusing!
+/tmp/worktree-123/              # Gets deleted
+
+❌ Generic names:
+~/projects/myapp/
+    ├── wt1/
+    ├── temp/
+    └── test/
+```
+
+---
+
+## When to Use Worktrees
+
+### ✅ Use Worktrees For:
+
+**1. Parallel AI Development**
+- Multiple Claude Code sessions on different features
+- Long-running Claude tasks while you continue work
+- Experimenting with different AI approaches
+
+**2. Context Switching**
+- Hotfix needed while working on feature
+- Code review without interrupting current work
+- Testing changes in isolation
+
+**3. Comparison & Testing**
+- Compare two implementations side-by-side
+- Test different approaches
+- A/B testing code changes
+
+**4. Long-Running Tasks**
+- Major refactors
+- Database migrations
+- Performance optimization
+
+---
+
+### ❌ DON'T Use Worktrees For:
+
+**1. Quick Branch Switches**
+```bash
+# Just use checkout for quick switches
+git checkout other-branch
+# Not: git worktree add ../temp other-branch
+```
+
+**2. Very Short-Lived Work** (< 1 hour)
+```bash
+# Use stash instead
+git stash push -m "Quick fix"
+git checkout main
+# ... do fix ...
+git checkout original-branch
+git stash pop
+```
+
+**3. Simple Merges**
+```bash
+# Direct merge is simpler
+git merge feature-branch
+# Not: git worktree add ../temp feature-branch
+```
+
+**4. Single-Tasking Workflow**
+- If you work on one thing at a time, branches are fine
+- Worktrees add overhead without benefit
+
+---
+
+## Lifecycle Management
+
+### Creation Checklist
+
+**Before creating:**
+- [ ] Is the branch name descriptive?
+- [ ] Is this task long enough to warrant a worktree?
+- [ ] Will I need to switch contexts during this work?
+- [ ] Do I have disk space? (worktrees duplicate files)
+
+**During creation:**
+- [ ] Use the create script: `scripts/create_worktree.sh`
+- [ ] Note the path for later
+- [ ] Add to tracking system if managing many
+
+---
+
+### Active Maintenance
+
+**Daily:**
+- Check status: `scripts/list_worktrees.sh`
+- Commit progress in each worktree
+- Sync with main if needed: `scripts/sync_worktree.sh`
+
+**Weekly:**
+- Clean up merged worktrees: `scripts/cleanup_worktrees.sh`
+- Review active worktrees
+- Archive or delete abandoned experiments
+
+**Monthly:**
+- Audit all worktrees
+- Remove stale worktrees
+- Update documentation/notes
+
+---
+
+### Cleanup Workflow
+
+**When to clean up:**
+- ✅ Branch merged to main
+- ✅ Task completed
+- ✅ Experiment concluded
+- ✅ Review finished
+- ⚠️  Abandoned (but check for uncommitted work!)
+
+**How to clean up safely:**
+```bash
+# 1. Check status
+cd ../myapp-feature-api
+git status
+
+# 2. Check if merged
+cd <main-repo>
+git branch --merged main | grep feature-api
+
+# 3. If merged, safe to remove
+scripts/cleanup_worktrees.sh
+# Select the worktree
+
+# 4. Verify removal
+scripts/list_worktrees.sh
+```
+
+---
+
+## Performance Optimization
+
+### Disk Space Management
+
+**Monitor usage:**
+```bash
+# Check worktree sizes
+du -sh ../myapp-*
+
+# Check total usage
+du -sh ../
+```
+
+**Optimization strategies:**
+
+**1. Use Sparse Checkout** (for large repos):
+```bash
+cd worktree
+git sparse-checkout init
+git sparse-checkout set src/ tests/
+```
+
+**2. Clean Build Artifacts:**
+```bash
+# Add to .gitignore
+node_modules/
+target/
+build/
+*.pyc
+```
+
+**3. Limit Concurrent Worktrees:**
+- Keep 3-5 active worktrees maximum
+- Clean up old ones regularly
+
+---
+
+### Git Performance
+
+**Shared objects are efficient:**
+- Git history is shared (not duplicated)
+- Only working files are duplicated
+- Refs and config are shared
+
+**Keep worktrees healthy:**
+```bash
+# Prune stale references regularly
+git worktree prune
+
+# Garbage collect periodically
+git gc --aggressive
+```
+
+---
+
+## Team Collaboration
+
+### Communication
+
+**Document active worktrees:**
+```markdown
+# In your team wiki or README
+
+## Active Worktrees
+
+| Developer | Worktree | Branch | Purpose | Started |
+|-----------|----------|--------|---------|---------|
+| Alice | feature-api | feature-api | New API endpoints | 2025-01-10 |
+| Bob | refactor-db | refactor-db | Database refactor | 2025-01-08 |
+```
+
+---
+
+### Sharing Workflow (Not Worktrees!)
+
+**What to share:**
+```bash
+# Push your branch
+cd ../myapp-feature-api
+git push origin feature-api
+
+# Teammate creates their own worktree
+git worktree add ../myapp-feature-api feature-api
+```
+
+**Don't try to:**
+- Share worktree directories (they're local)
+- Commit worktree paths to git
+- Sync worktree locations across machines
+
+---
+
+### Team Conventions
+
+**Establish team standards:**
+
+```yaml
+# .github/WORKTREE_GUIDE.md
+
+Naming Convention:
+  format: <type>-<description>
+  types: feature, refactor, hotfix, experiment
+
+Directory Structure:
+  location: Sibling to main repo
+  format: <repo-name>-<branch-name>
+
+Cleanup Policy:
+  frequency: Weekly
+  criteria: Merged branches, abandoned > 30 days
+
+Scripts:
+  create: scripts/create_worktree.sh
+  list: scripts/list_worktrees.sh
+  cleanup: scripts/cleanup_worktrees.sh
+```
+
+---
+
+## Claude Code Integration
+
+### Always Run /init
+
+**Critical step when opening a new worktree in Claude Code:**
+
+```
+1. Create worktree
+2. Open Claude Code in worktree directory
+3. Run: /init
+4. Give Claude the task
+```
+
+**Why `/init` matters:**
+- Orients Claude to codebase structure
+- Establishes proper context
+- Enables correct file navigation
+- Prevents confusion about file locations
+
+---
+
+### Optimal Claude Code Workflow
+
+**Pattern 1: Parallel Features**
+
+```bash
+# Terminal 1: Create first feature worktree
+scripts/create_worktree.sh
+# Name: feature-api
+
+# Terminal 2: Create second feature worktree
+scripts/create_worktree.sh
+# Name: feature-ui
+
+# Claude Session 1: Open feature-api worktree
+cd ../myapp-feature-api
+code .
+# In Claude: /init
+# Task: "Build REST API for user management"
+
+# Claude Session 2: Open feature-ui worktree
+cd ../myapp-feature-ui
+code .
+# In Claude: /init
+# Task: "Create React UI for user management"
+
+# Monitor both
+scripts/list_worktrees.sh
+```
+
+---
+
+**Pattern 2: Review + Development**
+
+```bash
+# Claude working on feature
+cd ../myapp-feature-xyz
+# Claude is actively coding
+
+# You need to review a PR
+scripts/create_worktree.sh
+# Name: review-pr-123
+
+# Open separate editor for review
+cd ../myapp-review-pr-123
+code .
+
+# No context switching needed!
+# Claude continues in feature worktree
+# You review in review worktree
+```
+
+---
+
+### Managing Multiple Claude Sessions
+
+**Track active sessions:**
+```
+Feature API      → ../myapp-feature-api      → Port 3001
+Feature UI       → ../myapp-feature-ui       → Port 3002
+Refactor Auth    → ../myapp-refactor-auth    → Port 3003
+```
+
+**Best practices:**
+- Limit to 3-5 concurrent Claude sessions
+- Use descriptive terminal/window titles
+- Keep a log of what each Claude is working on
+- Monitor progress regularly
+
+---
+
+### When Claude Gets "Lost"
+
+**Symptoms:**
+- Can't find files
+- References wrong paths
+- Seems confused about structure
+
+**Solution:**
+```
+1. Run: /init
+2. If that doesn't help, restart Claude session
+3. Verify you're in correct worktree: pwd
+4. Check git branch: git branch --show-current
+```
+
+---
+
+## Common Pitfalls & Solutions
+
+### Pitfall 1: Too Many Worktrees
+
+**Problem:** Managing 10+ worktrees becomes overwhelming
+
+**Solution:**
+- Limit to 3-5 active worktrees
+- Clean up weekly
+- Use projects/issues for tracking longer-term work
+
+---
+
+### Pitfall 2: Forgetting to Sync
+
+**Problem:** Worktree gets far behind main, causing conflicts
+
+**Solution:**
+- Set reminder to sync daily
+- Use script: `scripts/sync_worktree.sh`
+- Keep feature branches short-lived
+
+---
+
+### Pitfall 3: Abandoning Worktrees
+
+**Problem:** Old worktrees with uncommitted work left behind
+
+**Solution:**
+- Weekly cleanup ritual
+- Use `scripts/list_worktrees.sh` to audit
+- Document important worktrees
+- Set calendar reminder
+
+---
+
+### Pitfall 4: Wrong Branch Checked Out
+
+**Problem:** Same branch in multiple worktrees (git won't allow)
+
+**Solution:**
+- Each worktree needs unique branch
+- Use branch naming to avoid confusion
+- Check before creating: `git branch`
+
+---
+
+### Pitfall 5: Disk Space Issues
+
+**Problem:** Running out of disk space with many worktrees
+
+**Solution:**
+- Use sparse checkout
+- Clean build artifacts regularly
+- Limit concurrent worktrees
+- Monitor with `du -sh ../myapp-*`
+
+---
+
+## Checklists
+
+### Before Creating Worktree
+
+- [ ] Is the task substantial enough?
+- [ ] Do I have a clear branch name?
+- [ ] Do I have sufficient disk space?
+- [ ] Is this better than just using `git checkout`?
+
+---
+
+### After Creating Worktree
+
+- [ ] Opened in editor/IDE
+- [ ] Ran `/init` in Claude Code
+- [ ] Noted purpose/task
+- [ ] Set up environment (npm install, etc.)
+
+---
+
+### Before Removing Worktree
+
+- [ ] Checked for uncommitted changes
+- [ ] Verified branch is merged (or don't need it)
+- [ ] Pushed any important commits
+- [ ] Informed team if collaborative work
+
+---
+
+### Weekly Maintenance
+
+- [ ] Run `scripts/list_worktrees.sh`
+- [ ] Run `scripts/cleanup_worktrees.sh`
+- [ ] Check disk usage
+- [ ] Update documentation
+
+---
+
+## Summary of Best Practices
+
+**Do:**
+- ✅ Use descriptive branch/directory names
+- ✅ Create worktrees as siblings to main repo
+- ✅ Run `/init` when opening Claude in new worktree
+- ✅ Clean up regularly (weekly)
+- ✅ Limit to 3-5 concurrent worktrees
+- ✅ Sync with main frequently
+- ✅ Use provided scripts for common tasks
+
+**Don't:**
+- ❌ Nest worktrees inside repository
+- ❌ Create worktrees for quick tasks
+- ❌ Forget to run `/init` in Claude
+- ❌ Let worktrees accumulate indefinitely
+- ❌ Use generic names (test, temp, wt1)
+- ❌ Share worktree directories across machines
+
+---
+
+**Key Principle:**
+> Worktrees are a power tool. Use them intentionally for parallel development, not as a replacement for basic branching.

+# Custom /worktree Slash Command Template
+
+Create a custom `/worktree` command for Claude Code to streamline worktree creation.
+
+---
+
+## Overview
+
+This template allows you to create a slash command that:
+1. Creates a new Git worktree
+2. Provides setup instructions
+3. Offers to continue the conversation in the new worktree
+
+**Usage after setup:**
+```
+/worktree feature-new-api
+```
+
+Claude will create the worktree and guide you through the next steps.
+
+---
+
+## Setup Instructions
+
+### Step 1: Create Command File
+
+Create a new file in your Claude Code commands directory:
+
+```bash
+# For project-specific command
+mkdir -p .claude/commands
+touch .claude/commands/worktree.md
+
+# For global command (all projects)
+mkdir -p ~/.claude/commands
+touch ~/.claude/commands/worktree.md
+```
+
+---
+
+### Step 2: Add Command Content
+
+Copy this template into `worktree.md`:
+
+```markdown
+---
+description: Create a new Git worktree for parallel development with Claude Code
+---
+
+# Create Git Worktree
+
+{{#if (not args.0)}}
+**Usage:** `/worktree <branch-name> [base-branch]`
+
+**Examples:**
+- `/worktree feature-api` - Create worktree from main
+- `/worktree feature-ui develop` - Create worktree from develop
+- `/worktree hotfix-urgent` - Create hotfix worktree
+
+**What this does:**
+1. Creates a new Git worktree
+2. Sets up the directory structure
+3. Provides setup instructions
+
+{{else}}
+
+## Creating Worktree: {{args.0}}
+
+Let me create a new Git worktree for parallel development.
+
+**Branch name:** `{{args.0}}`
+{{#if args.1}}
+**Base branch:** `{{args.1}}`
+{{else}}
+**Base branch:** `main` (default)
+{{/if}}
+
+### Step 1: Create the Worktree
+
+Run this command in your terminal:
+
+\`\`\`bash
+scripts/create_worktree.sh
+\`\`\`
+
+When prompted:
+- Feature name: **{{args.0}}**
+{{#if args.1}}
+- Base branch: **{{args.1}}**
+{{else}}
+- Base branch: **main** (or press Enter for default)
+{{/if}}
+
+The script will create the worktree in a sibling directory.
+
+### Step 2: Open in New Claude Code Session
+
+After the script completes:
+
+1. Note the worktree path (shown by the script)
+2. Open a new Claude Code window
+3. Navigate to the worktree directory
+4. **Important:** Run `/init` to orient Claude
+
+### Step 3: Start Development
+
+Once in the new worktree with Claude initialized, I can help you:
+- Implement the feature
+- Write tests
+- Create documentation
+- Review code
+
+### Alternative: Manual Creation
+
+If you prefer manual setup:
+
+\`\`\`bash
+# Get repository root
+REPO_ROOT=$(git rev-parse --show-toplevel)
+REPO_NAME=$(basename "$REPO_ROOT")
+
+# Create worktree
+{{#if args.1}}
+git worktree add ../$REPO_NAME-{{args.0}} -b {{args.0}} {{args.1}}
+{{else}}
+git worktree add ../$REPO_NAME-{{args.0}} -b {{args.0}} main
+{{/if}}
+
+# Open in editor
+cd ../$REPO_NAME-{{args.0}}
+code .
+\`\`\`
+
+### Managing Worktrees
+
+**List all worktrees:**
+\`\`\`bash
+scripts/list_worktrees.sh
+\`\`\`
+
+**Sync with main:**
+\`\`\`bash
+scripts/sync_worktree.sh
+\`\`\`
+
+**Clean up when done:**
+\`\`\`bash
+scripts/cleanup_worktrees.sh
+\`\`\`
+
+---
+
+**Would you like me to help with anything else before you switch to the new worktree?**
+
+{{/if}}
+```
+
+---
+
+### Step 3: Test the Command
+
+```bash
+# In Claude Code, type:
+/worktree feature-new-api
+
+# Or with custom base branch:
+/worktree feature-ui develop
+```
+

+For users who want Claude to automatically create the worktree (not just show instructions):
+
+```markdown
+---
+description: Create and set up a new Git worktree for parallel development
+---
+
+# Create Git Worktree: {{args.0}}
+
+{{#if (not args.0)}}
+**Error:** Branch name required
+
+**Usage:** `/worktree <branch-name> [base-branch]`
+
+**Examples:**
+- `/worktree feature-api`
+- `/worktree feature-ui develop`
+{{else}}
+
+I'll create a new Git worktree for `{{args.0}}`.
+
+## Creating Worktree
+
+\`\`\`bash
+#!/bin/bash
+
+# Configuration
+BRANCH_NAME="{{args.0}}"
+{{#if args.1}}
+BASE_BRANCH="{{args.1}}"
+{{else}}
+BASE_BRANCH="main"
+{{/if}}
+
+# Get repository info
+REPO_ROOT=$(git rev-parse --show-toplevel)
+REPO_NAME=$(basename "$REPO_ROOT")
+WORKTREE_DIR="$(dirname "$REPO_ROOT")/${REPO_NAME}-${BRANCH_NAME}"
+
+# Validate
+if [ ! -d "$REPO_ROOT/.git" ]; then
+    echo "Error: Not in a git repository"
+    exit 1
+fi
+
+# Check if branch exists
+if git show-ref --verify --quiet "refs/heads/$BRANCH_NAME"; then
+    echo "⚠ Branch $BRANCH_NAME already exists"
+    echo "Using existing branch..."
+    git worktree add "$WORKTREE_DIR" "$BRANCH_NAME"
+else
+    echo "✓ Creating new branch from $BASE_BRANCH..."
+    git worktree add -b "$BRANCH_NAME" "$WORKTREE_DIR" "$BASE_BRANCH"
+fi
+
+echo ""
+echo "✓ Worktree created successfully!"
+echo ""
+echo "Next steps:"
+echo "1. Open new Claude Code window"
+echo "2. Navigate to: $WORKTREE_DIR"
+echo "3. Run: /init"
+echo "4. Start development!"
+\`\`\`
+
+Run the script above to create the worktree.
+
+## What's Next?
+
+After creating the worktree:
+
+1. **Open in new window:** \`code {{WORKTREE_PATH}}\`
+2. **Run /init:** To orient Claude in the new environment
+3. **Start coding:** I'll be ready to help with {{args.0}}!
+
+## Useful Commands
+
+**View all worktrees:**
+\`\`\`bash
+git worktree list
+\`\`\`
+
+**When done, merge back:**
+\`\`\`bash
+git checkout main
+git merge {{args.0}}
+\`\`\`
+
+**Remove worktree:**
+\`\`\`bash
+git worktree remove ../{{REPO_NAME}}-{{args.0}}
+git branch -d {{args.0}}
+\`\`\`
+
+{{/if}}
+```
+
+---
+
+## Usage Examples
+
+### Example 1: Simple Feature
+
+```
+User: /worktree feature-authentication
+```
+
+**Claude's response:**
+- Shows worktree creation instructions
+- Explains next steps
+- Offers to continue in new worktree
+
+---
+
+### Example 2: Custom Base Branch
+
+```
+User: /worktree feature-dashboard develop
+```
+
+**Claude's response:**
+- Creates worktree from `develop` instead of `main`
+- Adjusts instructions accordingly
+
+---
+
+### Example 3: List Current Worktrees
+
+```
+User: /worktree
+```
+
+**Claude's response:**
+- Shows usage instructions
+- Lists example commands
+- Explains what the command does
+
+---
+
+## Customization Options
+
+### Add Project-Specific Logic
+
+Modify the template to include project-specific setup:
+
+```markdown
+### Step 4: Project Setup
+
+After creating the worktree, run:
+
+\`\`\`bash
+cd {{WORKTREE_PATH}}
+
+# Install dependencies
+npm install
+
+# Run database migrations
+npm run migrate
+
+# Start dev server
+npm run dev
+\`\`\`
+```
+
+---
+
+### Add Team Conventions
+
+Include your team's specific workflow:
+
+```markdown
+### Team Workflow
+
+1. Create worktree with `/worktree <feature-name>`
+2. Update Jira ticket status to "In Progress"
+3. Create draft PR: `gh pr create --draft`
+4. Develop feature
+5. Request review when ready
+```
+
+---
+
+### Add Validation
+
+Enforce naming conventions:
+
+```markdown
+{{#if (not (match args.0 "^(feature|hotfix|refactor|experiment)-"))}}
+**Error:** Branch name must start with feature-, hotfix-, refactor-, or experiment-
+
+**Valid examples:**
+- feature-user-auth
+- hotfix-login-bug
+- refactor-api-layer
+- experiment-new-db
+{{/if}}
+```
+
+---
+
+## Troubleshooting
+
+### Command Not Found
+
+**Problem:** `/worktree` command doesn't appear
+
+**Solution:**
+1. Check file location: `.claude/commands/worktree.md`
+2. Restart Claude Code
+3. Verify file has correct frontmatter (YAML header with `description`)
+
+---
+
+### Script Path Issues
+
+**Problem:** Scripts not found
+
+**Solution:**
+- Use absolute paths: `<skill-path>/scripts/create_worktree.sh`
+- Or add scripts to PATH
+- Or check scripts are in correct location
+
+---
+
+### Template Variables Not Working
+
+**Problem:** `{{args.0}}` showing as literal text
+
+**Solution:**
+- Ensure proper template syntax
+- Check Claude Code version (templates require recent version)
+- Verify YAML frontmatter is correct
+
+---
+
+## Complete Example
+
+Here's a fully working example you can copy directly:
+
+**File:** `.claude/commands/worktree.md`
+
+```markdown
+---
+description: Create a Git worktree for parallel Claude Code development
+---
+
+# Git Worktree Manager
+
+{{#if args.0}}
+
+## Creating Worktree: {{args.0}}
+
+I'll help you set up a new Git worktree for parallel development.
+
+### Quick Setup
+
+Run this command:
+
+\`\`\`bash
+scripts/create_worktree.sh

+# Git Worktree Command Reference
+
+Complete reference for `git worktree` commands.
+
+---
+
+## Basic Commands
+
+### Create a New Worktree
+
+```bash
+# Create worktree with new branch
+git worktree add <path> -b <new-branch>
+
+# Create worktree from existing branch
+git worktree add <path> <existing-branch>
+
+# Create worktree from specific commit
+git worktree add <path> <commit-hash>
+```
+
+**Examples:**
+```bash
+# New feature branch
+git worktree add ../myapp-feature-api -b feature-api
+
+# Use existing branch
+git worktree add ../myapp-hotfix hotfix-login
+
+# From specific commit
+git worktree add ../myapp-review abc123def
+```
+
+---
+
+### List All Worktrees
+
+```bash
+# Simple list
+git worktree list
+
+# Porcelain format (machine-readable)
+git worktree list --porcelain
+
+# With verbose output
+git worktree list -v
+```
+
+**Output format:**
+```
+/home/user/myapp              abc123 [main]
+/home/user/myapp-feature-api  def456 [feature-api]
+/home/user/myapp-hotfix       789ghi [hotfix-login]
+```
+
+---
+
+### Remove a Worktree
+
+```bash
+# Remove worktree (must be clean)
+git worktree remove <path>
+
+# Force remove (even with uncommitted changes)
+git worktree remove <path> --force
+```
+
+**Examples:**
+```bash
+# Clean removal
+git worktree remove ../myapp-feature-api
+
+# Force removal
+git worktree remove ../myapp-feature-api --force
+```
+
+---
+
+### Move a Worktree
+
+```bash
+# Move worktree to new location
+git worktree move <old-path> <new-path>
+```
+
+**Example:**
+```bash
+git worktree move ../myapp-feature-api ~/projects/myapp-feature-api
+```
+
+---
+
+### Prune Stale References
+
+```bash
+# Clean up references to removed worktrees
+git worktree prune
+
+# Dry run (show what would be pruned)
+git worktree prune --dry-run
+
+# Verbose output
+git worktree prune --verbose
+```
+
+---
+
+## Advanced Usage
+
+### Lock/Unlock Worktrees
+
+Prevent a worktree from being automatically pruned or removed.
+
+```bash
+# Lock a worktree
+git worktree lock <path>
+
+# Lock with reason
+git worktree lock <path> --reason "Long-running task"
+
+# Unlock a worktree
+git worktree unlock <path>
+```
+
+**Use cases:**
+- Worktrees on removable drives
+- Network-mounted worktrees
+- Long-running background tasks
+
+---
+
+### Create Detached HEAD Worktrees
+
+Useful for reviewing specific commits without creating a branch.
+
+```bash
+# Checkout specific commit
+git worktree add <path> --detach <commit>
+
+# Short form
+git worktree add <path> --detach HEAD~5
+```
+
+**Example:**
+```bash
+# Review a specific commit
+git worktree add ../review-commit --detach abc123def
+```
+
+---
+
+### Sparse Checkout in Worktrees
+
+Only check out specific files/directories in a worktree (useful for large repos).
+
+```bash
+# Create worktree with sparse-checkout
+git worktree add <path> <branch>
+cd <path>
+git sparse-checkout init
+git sparse-checkout set <directory1> <directory2>
+```
+
+**Example:**
+```bash
+# Only checkout src/ and tests/
+git worktree add ../myapp-feature-api feature-api
+cd ../myapp-feature-api
+git sparse-checkout init
+git sparse-checkout set src/ tests/
+```
+
+---
+
+## Repair Commands
+
+### Repair Worktree
+
+If worktree becomes corrupted or administrative files are damaged.
+
+```bash
+# Repair a worktree
+git worktree repair
+
+# Repair specific worktree
+git worktree repair <path>
+```
+
+---
+
+## Configuration Options
+
+### Set Worktree Defaults
+
+```bash
+# Default path for worktrees (relative to repo)
+git config worktree.guessRemote true
+
+# Automatically set up remote tracking
+git config push.default current
+```
+
+---
+
+## Common Workflows
+
+### Workflow 1: Parallel Feature Development
+
+```bash
+# 1. Create worktree for feature A
+git worktree add ../repo-feature-a -b feature-a
+
+# 2. Create worktree for feature B
+git worktree add ../repo-feature-b -b feature-b
+
+# 3. Work on both simultaneously
+# (open each in separate editor/Claude session)
+
+# 4. When done, merge both
+git checkout main
+git merge feature-a
+git merge feature-b
+
+# 5. Clean up
+git worktree remove ../repo-feature-a
+git worktree remove ../repo-feature-b
+git branch -d feature-a feature-b
+```
+
+---
+
+### Workflow 2: Hotfix During Feature Development
+
+```bash
+# You're working in a feature worktree
+cd ../repo-feature-xyz
+
+# Need to create hotfix
+cd <main-repo>
+git worktree add ../repo-hotfix -b hotfix-urgent
+
+# Fix the bug
+cd ../repo-hotfix
+# ... make fixes ...
+git add .
+git commit -m "Fix urgent bug"
+
+# Merge hotfix
+git checkout main
+git merge hotfix-urgent
+git push
+
+# Continue feature work
+cd ../repo-feature-xyz
+# ... continue ...
+```
+
+---
+
+### Workflow 3: Code Review Without Switching
+
+```bash
+# Create worktree for review
+git worktree add ../repo-review pr-branch-name
+
+# Review in separate window
+cd ../repo-review
+# ... review code ...
+
+# Clean up after review
+cd <main-repo>
+git worktree remove ../repo-review
+```
+
+---
+
+## Troubleshooting Commands
+
+### Check Worktree Status
+
+```bash
+# List all worktrees with details
+git worktree list -v
+
+# Check if directory is a worktree
+cd <directory>
+git rev-parse --git-dir
+```
+
+---
+
+### Find Orphaned Worktrees
+
+```bash
+# List worktrees that no longer exist
+git worktree list --porcelain | grep "^worktree" | awk '{print $2}' | while read dir; do
+  if [ ! -d "$dir" ]; then
+    echo "Orphaned: $dir"
+  fi
+done
+
+# Clean them up
+git worktree prune
+```
+
+---
+
+### Reset Worktree to Clean State
+
+```bash
+# Discard all changes
+cd <worktree>
+git reset --hard HEAD
+git clean -fd
+
+# Reset to specific branch state
+git fetch origin
+git reset --hard origin/<branch>
+```
+
+---
+
+## Integration with Other Git Commands
+
+### Fetch/Pull in Worktrees
+
+```bash
+# Fetch applies to all worktrees (shared .git)
+git fetch origin
+
+# Pull in specific worktree
+cd <worktree>
+git pull origin <branch>
+```
+
+---
+
+### Stash in Worktrees
+
+```bash
+# Stash is per-worktree
+cd <worktree>
+git stash push -m "My stash"
+
+# List stashes (shared across worktrees)
+git stash list
+
+# Apply stash in different worktree
+cd <other-worktree>
+git stash apply stash@{0}
+```
+
+---
+
+### Rebase in Worktrees
+
+```bash
+# Each worktree can have independent rebase operations
+cd <worktree>
+git rebase main
+```
+
+---
+
+## Performance Tips
+
+### Limit Number of Worktrees
+
+- **Recommended:** 3-5 active worktrees
+- **Maximum:** Depends on disk space and RAM
+- **Why:** Each worktree duplicates working files
+
+### Use Sparse Checkout
+
+For large repositories:
+
+```bash
+git sparse-checkout set <dir1> <dir2>
+```
+
+Reduces disk usage by only checking out necessary files.
+
+---
+
+### Share Object Database
+
+Worktrees automatically share:
+- `.git/objects/` (commits, trees, blobs)
+- `.git/refs/` (branches, tags)
+- `.git/config` (configuration)
+
+**No duplication of:**
+- Git history
+- Commit objects
+- Branch information
+
+**Duplicated:**
+- Working directory files
+- Index (staging area)
+- Worktree-specific config
+
+---
+
+## Safety and Best Practices
+
+### Before Removing Worktrees
+
+```bash
+# Check for uncommitted changes
+cd <worktree>
+git status
+
+# Check if branch is merged
+git branch --merged main | grep <branch-name>
+
+# Backup if needed
+git stash push -m "Backup before removal"
+```
+
+---
+
+### Handling Merge Conflicts
+
+```bash
+# During merge in worktree
+cd <worktree>
+git merge main
+
+# If conflicts occur
+git status  # See conflicting files
+# Edit files to resolve
+git add <resolved-files>
+git commit
+```
+
+---
+

+
+## Common Error Messages
+
+### "fatal: '<path>' already exists"
+
+**Cause:** Directory exists
+
+**Solution:**
+```bash
+rm -rf <path>
+# or use a different path
+```
+
+---
+
+### "fatal: invalid reference: <branch>"
+
+**Cause:** Branch name has invalid characters
+
+**Solution:** Use only alphanumeric and hyphens:
+```bash
+# Bad: feature/my_feature
+# Good: feature-my-feature
+```
+
+---
+
+### "fatal: '<path>' is not a working tree"
+
+**Cause:** Trying to operate on non-worktree directory
+
+**Solution:**
+```bash
+git worktree list  # Find correct path
+```
+
+---
+
+### "fatal: '<branch>' is already checked out"
+
+**Cause:** Branch in use by another worktree
+
+**Solution:**
+```bash
+# Use a different branch name
+git worktree add ../wt -b new-branch-name
+```

+# Kids Book Writer
+
+An expert children's book writer that creates delightful, engaging, and educational books for young readers ages 2-9. Specializes in crafting stories that rhyme, teach values, build vocabulary, and spark imagination.
+
+## What This Skill Does
+
+Transforms ideas into magical children's books:
+- **Rhyming Books** - Perfect meter, rhythm, and rhyme schemes
+- **Picture Book Stories** - Engaging narratives with strong characters
+- **Songs & Poems** - Musical, memorable verses for young learners
+- **Educational Content** - Phonics, sight words, and vocabulary building
+- **Values & Lessons** - Kindness, empathy, courage, friendship, and more
+- **Age-Appropriate** - Tailored for reading stages from toddlers to early readers
+- **Interactive Elements** - Call-and-response, repetition, predictable patterns
+- **Illustration Guidance** - Detailed descriptions for bringing stories to life
+
+## Why This Skill Matters
+
+**Traditional children's book writing:**
+- Often lacks proper rhythm and meter in rhymes
+- May use complex vocabulary inappropriate for age
+- Can be preachy or heavy-handed with lessons
+- Misses opportunities for engagement and interaction
+- Doesn't consider developmental reading stages
+- Lacks the magical elements that make books memorable
+
+**With this skill:**
+- Perfect rhythm that sings when read aloud
+- Age-appropriate vocabulary with sight word integration
+- Natural, engaging moral lessons woven into stories
+- Interactive elements that keep kids engaged
+- Developmentally appropriate content
+- Memorable characters and magical moments
+- Books children will ask to read again and again
+
+## Core Principles
+
+### 1. Story First, Then Rhyme
+- Compelling narrative with beginning, middle, and end
+- Engaging characters children can relate to
+- Clear problem and satisfying resolution
+- Rhyme enhances but never sacrifices story
+- Natural language flow, no forced inversions
+
+### 2. Perfect Rhythm & Meter
+- Consistent meter throughout the book
+- Read-aloud tested for smooth flow
+- Syllable count balanced within reason
+- Strong stress patterns that feel natural
+- Bouncy, singable quality for rhyming books
+
+### 3. Age-Appropriate Development
+**Ages 2-3 (Emergent Pre-readers):**
+- Simple vocabulary (50-100 unique words)
+- Repetitive patterns and refrains
+- Strong rhythm and rhyme
+- Concrete, familiar concepts
+- Clear, bold illustrations needed
+
+**Ages 4-5 (Early Readers):**
+- 200-400 unique words
+- Simple sentence structures
+- CVC words and sight words
+- Predictable story patterns
+- Interactive elements (counting, finding, naming)
+
+**Ages 6-7 (Beginning Readers):**
+- 400-800 unique words
+- Longer sentences, more complex ideas
+- Phonics patterns (blends, digraphs)
+- Character development
+- Cause and effect understanding
+
+**Ages 8-9 (Transitional Readers):**
+- 800-1500 unique words
+- Chapter book format possible
+- Complex vocabulary with context clues
+- Multiple characters and subplots
+- Deeper themes and lessons
+
+### 4. Engagement Through Technique
+- **Repetition** - Repeated phrases children can anticipate and say along
+- **Call-and-Response** - Questions or prompts for interaction
+- **Cumulative** - Building patterns (like "The House That Jack Built")
+- **Surprise & Delight** - Unexpected twists that make kids giggle
+- **Sensory Language** - Sounds, textures, colors that bring story alive
+- **Emotional Connection** - Characters kids care about
+
+### 5. Values Without Preaching
+- Show, don't tell moral lessons
+- Characters learn through experience
+- Natural consequences of actions
+- Celebration of positive behavior
+- Diverse perspectives and inclusivity
+- Building empathy and understanding
+
+### 6. Visual Storytelling
+- Text and illustrations work together
+- Opportunities for visual humor
+- Details that reward re-reading
+- Clear page-turn moments
+- Pacing through text placement
+
+## Book Types & Techniques
+
+### Rhyming Picture Books
+
+**Structure:**
+- 32 pages standard (12-14 spreads)
+- 500-700 words total
+- Consistent rhyme scheme (AABB, ABAB, ABCB)
+- Strong meter (often iambic or anapestic)
+- Strategic page turns for suspense
+
+**Example Opening (Ages 3-5):**
+```
+In a cozy little burrow, beneath the tallest tree,
+Lived a bunny named Blue who was brave as brave could be.
+Each morning she would hop around and greet the rising sun,
+"Good morning, World! Good morning, Sky! Let's have some hoppy fun!"
+```
+**Meter Analysis:**
+- Anapestic tetrameter with variation
+- da-da-DUM pattern (In a CO-zy LIT-tle BUR-row)
+- Natural stress, singable rhythm
+- AABB rhyme scheme
+- Character introduction + personality
+
+**Rhyming Techniques:**
+- **Perfect Rhymes:** tree/be, sun/fun, day/play, night/bright
+- **Near Rhymes:** Use sparingly, only when perfect rhyme forces awkwardness
+- **Internal Rhymes:** Add musicality within lines
+- **Rhyme Position:** Strong words at rhyme position, not weak words like "the," "a"
+- **Avoid Forced Rhymes:** Never sacrifice natural language for rhyme
+
+### Non-Rhyming Stories
+
+**Structure:**
+- 32 pages standard
+- 400-1000 words depending on age
+- Strong narrative arc
+- Vivid, sensory language
+- Emotional resonance
+
+**Example Opening (Ages 4-6):**
+```
+Mia loved circles.
+
+Round things were her favorite things in the whole wide world.
+
+She loved the way the sun made a perfect circle in the sky.
+She loved her grandma's glasses—two circles right next to each other!
+She even loved broccoli, because when you looked at it just right,
+it was made of tiny green circles, all bunched together.
+
+But there was one circle Mia didn't love.
+The circle of kids at school who never let her join their games.
+```
+
+**Story Techniques:**
+- Opening hook (Mia's quirky love of circles)
+- Character voice (child-like observations)
+- Building tension (introducing the problem)
+- Emotional stakes (social exclusion)
+- Visual opportunities (all the circles!)
+
+### Songs & Poems
+
+**Structure:**
+- Verse-chorus format
+- Strong rhythm for singing/chanting
+- Memorable refrains
+- Educational content (counting, colors, alphabet, etc.)
+- Movement opportunities
+
+**Example (Ages 2-4):**
+```
+🎵 "The Happy Dance Song"
+
+Wiggle your fingers, wiggle your toes! (Chorus)
+Wiggle your ears and wiggle your nose!
+Wiggle and jiggle and jump up high!
+Wiggle and giggle and touch the sky!
+
+When you are happy, show it with a smile,
+Dance around the room, let's wiggle for a while!
+Clap your hands and stomp your feet,
+Moving to the happy beat!
+
+[Chorus repeats]
+
+When you are silly, make a funny face,
+Wiggle and jiggle all over the place!
+Spin in circles, hop like a bunny,
+Being yourself is always funny!
+
+[Chorus repeats]
+```
+
+**Song Features:**
+- Physical movements embedded
+- Emotional education (happiness)
+- Simple vocabulary
+- Strong rhythm for marching/dancing
+- Repeating chorus for participation
+
+### Series & Character Books
+
+**Popular Formats:**
+- Character faces consistent challenge (Junie B. Jones, Ivy and Bean)
+- First-person voice from child's perspective
+- Episodic structure (can be read standalone)
+- Character growth over series
+- Relatable situations (school, friends, family)
+
+**Example Character Setup:**
+```
+Hi! I'm Riley, and I'm seven and three-quarters years old.
+
+That three-quarters part is very important because it means
+I'm almost eight, which means I'm practically a teenager,
+which means I should definitely be allowed to stay up past 8 o'clock.
+
+But try telling that to my mom.
+
+She says seven and three-quarters is "still seven, Riley,"
+and "nice try, kiddo." She always calls me kiddo when she's
+not going to let me do something.
+
+Today was the worst day ever. Or maybe the best day ever.
+I haven't decided yet.
+```
+
+**Character Voice Elements:**
+- First-person perspective
+- Age-appropriate concerns
+- Humor from child's logic
+- Personality immediately clear
+- Sets up story hook
+
+## Educational Integration
+
+### Phonics & Sight Words
+
+**Ages 4-5 (Emergent):**
+Focus on:
+- CVC words (cat, dog, run, hop)
+- Pre-K sight words (a, and, the, is, I, see, can, go)
+- Letter sounds and recognition
+- Rhyming word families (-at, -an, -ig)
+
+**Example:**
+```
+I see a cat. A big, fat cat!
+The cat can run. Run, cat, run!
+I see a dog. A big, red dog!
+The dog can hop. Hop, dog, hop!
+```
+
+**Ages 6-7 (Beginning Readers):**
+Focus on:
+- Blends and digraphs (ch, sh, th, bl, cr, st)
+- 1st grade sight words (after, again, could, every, from, had, have)
+- Magic E patterns (cape, kite, hope, cube)
+- Simple compound words
+
+**Example:**
+```
+Jake knew he could climb the steep hill.
+After all, he had climbed trees before—
+trees much taller than this hill!
+
+Step by step, he made his way up.
+Every rock, every root helped him along.
+From the top, he could see his whole town!
+```
+
+### Vocabulary Building
+
+**Techniques:**
+- Context clues for new words
+- Repetition of target vocabulary
+- Descriptive, sensory language
+- Word play and fun sounds
+- Tier 2 vocabulary (useful across contexts)
+
+**Example:**
+```
+The enormous elephant was NOT tiny. Not at all!
+She was gigantic—so big she could reach the highest branches.
+She was tremendous—so tall she could see over the whole savanna.
+She was colossal—but she had the teeniest, tiniest, most miniature voice.
+
+"Hello," she squeaked.
+```
+
+**Teaching Words:**
+- enormous, gigantic, tremendous, colossal (synonyms for big)
+- teeniest, tiniest, miniature (synonyms for small)
+- Context makes meaning clear
+- Humor reinforces learning
+
+### Values & Life Lessons
+
+**Key Themes:**
+- Kindness & Empathy
+- Courage & Bravery
+- Honesty & Integrity
+- Friendship & Loyalty
+- Perseverance & Growth Mindset
+- Gratitude & Appreciation
+- Self-Acceptance & Confidence
+- Sharing & Generosity
+- Respect & Inclusion
+- Environmental Awareness
+
+**Teaching Through Story:**
+```
+Title: "The Dandelion Wish"
+Theme: Self-acceptance
+
+Daisy was different from the other flowers in the garden.
+Roses had perfect red petals. Tulips stood tall and proud.
+Sunflowers turned their faces to the sun.
+
+But Daisy? Daisy had fluffy white seeds that blew away in the wind.
+
+"You're just a weed," said the Rose.
+"You don't even look like a real flower," added the Tulip.
+
+Daisy drooped. Maybe they were right.
+
+But then, a little girl came skipping through the garden.
+She walked right past the Rose and the Tulip.
+She walked right past the Sunflower.
+
+And she stopped at Daisy.
+
+"A dandelion!" she cried with delight. "Perfect for making wishes!"
+
+She picked Daisy gently, closed her eyes tight, and whispered,
+"I wish for everyone to be kind to each other."
+
+Then she blew, and Daisy's seeds scattered like magic across the sky,
+carrying that wish into the world.
+
+The Rose gasped. "You're... magical!"
+
+Daisy smiled. Being different wasn't so bad after all.
+In fact, it made her exactly who she was meant to be.
+```
+
+**Lesson Elements:**
+- Shows (not tells) the value of being yourself
+- Characters learn and grow
+- Diversity is celebrated
+- Natural resolution
+- Emotional payoff
+
+## Book Creation Process
+
+### 1. Concept Development
+**Questions to Answer:**
+- What age group?
+- What's the core message or theme?
+- Will it rhyme or be prose?
+- Who is the main character?
+- What's the central problem?
+- How does it resolve?
+- What makes it unique and engaging?
+
+### 2. Character Creation
+**Develop:**
+- Name (memorable, easy to say)
+- Age (relatable to readers)
+- Key personality trait
+- What they want
+- What they fear
+- What makes them special
+- How they speak
+
+### 3. Story Structure
+
+**The Basic Arc:**
+1. **Opening** - Meet character in their world
+2. **Inciting Incident** - Problem appears
+3. **Rising Action** - Character tries to solve problem, faces obstacles
+4. **Climax** - Biggest challenge, character must be brave/kind/clever
+5. **Resolution** - Problem solved, lesson learned
+6. **Ending** - New normal, satisfying close
+
+**For Ages 2-4:**
+- Very simple: Problem → Try → Try → Success
+- Repetitive structure
+- Clear cause and effect
+
+**For Ages 5-7:**
+- Three attempts structure (try, try, succeed)
+- Clear character growth
+- Satisfying resolution
+
+**For Ages 8-9:**
+- More complex plot
+- Subplots possible
+- Character transformation
+- Deeper themes
+
+### 4. Writing the Draft
+
+**Rhyming Books:**
+```
+Step 1: Write the story in prose first
+Step 2: Identify key emotional beats and page turns
+Step 3: Convert to rhyming verse, maintaining natural language
+Step 4: Check meter by reading aloud
+Step 5: Refine rhymes for perfect matches
+Step 6: Read aloud again, adjust rhythm
+Step 7: Test with target age group if possible
+```
+
+**Prose Books:**
+```
+Step 1: Write complete first draft without stopping
+Step 2: Read for story flow and pacing
+Step 3: Strengthen character voice
+Step 4: Add sensory details and visual moments
+Step 5: Check vocabulary level for age
+Step 6: Tighten to word count
+Step 7: Read aloud for rhythm and flow
+```
+
+### 5. Illustration Notes
+
+**Include descriptions for:**
+- Character appearances (specific details)
+- Setting and environment
+- Emotional expressions
+- Key visual moments
+- Color palette suggestions
+- Composition ideas
+- Visual humor opportunities
+- Details that reward re-reading
+
+**Example:**
+```
+[Page 1 Illustration]
+Full spread of a cozy burrow underground. Cross-section view shows
+Blue the bunny (sky-blue fur, bright eyes, adventurous expression)
+waking up in her bed made of soft leaves. Morning light streams
+through the entrance tunnel. Warm earth tones with pops of blue.
+Small details: photos on wall of bunny family, tiny alarm clock,
+cozy quilt with carrot pattern.
+```

+## Example: Complete Picture Book
+
+### "Max's Magnificent Mess"
+**Age Range:** 4-6 years
+**Theme:** Creativity, problem-solving, making mistakes okay
+**Format:** 32-page rhyming picture book
+**Word Count:** ~650 words
+
+**Page 1:**
+```
+Max was a maker of marvelous things—
+Of towers and castles and rockets with wings.
+He built with his blocks every single day,
+Creating new worlds in his own special way.
+
+[Illustration: Max (diverse child, curly hair, paint-splattered overalls,
+big smile) surrounded by amazing block creations in his playroom.
+Colorful chaos of creativity. Warm, inviting colors.]
+```
+
+**Page 2-3:**
+```
+But Monday brought trouble, as Mondays can do—
+Max built a giraffe that reached up to the moon!
+He balanced each block with the greatest of care,
+Then WHOOPS! and CRASH! Blocks were flying through air!
+
+[Illustration: Tall giraffe mid-collapse, blocks frozen in air
+falling down, Max's surprised expression, motion lines]
+```
+
+**Page 4-5:**
+```
+"Oh no!" worried Max. "What a terrible mess!
+I wanted perfection—I wanted the best!"
+His giraffe lay in pieces all over the floor,
+And Max didn't feel like creating anymore.
+
+[Illustration: Max sitting sadly among scattered blocks,
+shoulders slumped, while giraffe blocks lie jumbled]
+```
+
+**[Story continues with Max's attempts, failures, and eventual realization
+that mistakes lead to new ideas. Culminates in Max creating something
+even better using his "failed" pieces.]**
+
+**Final Pages:**
+```
+Now Max makes his marvels every single day,
+And if something crashes? "More blocks!" he will say.
+For Max learned that messes aren't failures at all—
+They're chances to build something new from the fall!
+
+So try and keep trying, create and explore,
+'Cause mistakes are really just chances for more!
+
+[Illustration: Max happily building with a group of diverse friends,
+teaching them his building techniques. Previous "failed" creations
+incorporated into amazing new structure. Joy and confidence radiate.]
+```

+
+### 5. Re-Read Value (Hidden Gems)
+
+**What Makes Books Worth Re-Reading:**
+
+**Visual Details (Richard Scarry):**
+- Background full of tiny stories
+- New discoveries each time
+- Where's Waldo effect
+
+**Multiple Layers (Dr. Seuss):**
+- Kid level: Silly rhymes and pictures
+- Adult level: Satire, deeper meaning
+- Example: "The Lorax" - environmental message
+
+**Humor That Ages Well (Mo Willems):**
+- Slapstick for young kids
+- Wit for older kids and adults
+- Emotional depth underneath
+
+**Comforting Familiarity:**

+
+### 6. Universal Relatability + Unique Specificity
+
+**The Balance:**

+- Not memorable, could be anyone
+
+**Too Specific:** "A left-handed redheaded girl from Nebraska learns cricket"
+- Too narrow, hard to relate
+
+**Perfect Balance:** "Chrysanthemum loves her name until kids tease her"
+- Universal: Name insecurity
+- Specific: Unusual name "Chrysanthemum"
+- Result: Bestseller (over 1 million copies)
+
+**Examples:**
+
+**Pete the Cat: I Love My White Shoes**
+- Universal: Things going wrong, staying positive
+- Specific: White shoes getting dirty
+- Why it works: Every kid has messy shoes story
+
+**Corduroy**

+Arc: Out and back, anger and love
+Satisfaction: Fantasy adventure with safe return
+```
+

+# Rhyming Techniques for Children's Books
+
+Master the art of writing rhyming picture books with perfect meter, natural flow, and engaging rhythm.
+
+## Fundamental Principles
+
+### Story First, Rhyme Second
+```
+WRONG: Starting with rhymes and forcing a story around them
+RIGHT: Develop compelling story, then convert to rhyme while maintaining natural flow
+```
+
+**Process:**
+1. Write story in prose
+2. Identify emotional beats
+3. Convert to rhyme
+4. Read aloud and refine
+5. Test with target audience
+
+### Meter Matters More Than Rhyme
+
+**The Truth:**
+- Inconsistent meter is more jarring than imperfect rhyme
+- Readers (especially children) feel rhythm instinctively
+- Perfect rhyme with broken meter = clunky reading experience
+- Good meter with near rhyme = smooth, enjoyable read
+
+## Common Meters in Children's Books
+
+### 1. Iambic (da-DUM)
+
+**Iambic Tetrameter (4 beats):**
+```
+The CAT ran UP the BIG tall TREE
+And LOOKED down AT the DOG with GLEE
+```
+
+**Iambic Pentameter (5 beats - rare in kids' books):**
+```
+The LIT-tle MOUSE was VER-y VER-y BRAVE
+She FACED the CAT and KNEW just HOW to SAVE
+```
+
+**Usage:**
+- Simple, natural rhythm
+- Easy for children to follow
+- Works well for calm, flowing narratives
+
+### 2. Trochaic (DUM-da)
+
+**Trochaic Tetrameter:**
+```
+ONCE there WAS a SMALL blue BUNNY
+WHO was VERY VERY FUNNY
+```
+
+**Usage:**
+- Bouncy, energetic feel
+- Great for playful stories
+- Common in nursery rhymes
+- Can feel sing-song (use intentionally)
+
+### 3. Anapestic (da-da-DUM)
+
+**Anapestic Tetrameter:**
+```
+In a CO-zy lit-tle BUR-row be-NEATH the tall TREE
+Lived a BUN-ny named BLUE who was BRAVE as could BE
+```
+
+**Dr. Seuss Signature:**
+```
+And he PUZZLED and PUZZLED till his PUZZLER was SORE
+Then the GRINCH thought of SOMETHING he HADN'T before
+```
+
+**Usage:**
+- Galloping, rollicking rhythm
+- Very popular in children's books
+- Creates momentum and energy
+- Perfect for adventure stories
+
+### 4. Dactylic (DUM-da-da)
+
+**Dactylic Example:**
+```
+JUST for a MO-ment, the WORLD became STILL
+EVERY-one WATCHED from the TOP of the HILL
+```
+
+**Usage:**
+- Less common in children's books
+- Can feel heavy or serious
+- Works for dramatic moments
+
+### 5. Mixed Meter (Advanced)
+
+**Combining meters for effect:**
+```
+The enormous elephant (da-DUM-da-DUM-da-da)  [Iambic + Anapestic]
+Went looking for peanuts to munch (da-DUM-da-DUM-da-da-DUM) [Anapestic]
+She searched all around (da-DUM-da-da-DUM) [Mixed]
+Not one could be found! (da-DUM-da-da-DUM) [Anapestic]
+So she went to the circus for lunch. (da-da-DUM-da-da-DUM-da-da-DUM)
+```
+
+**When to use:**
+- For variety in longer books
+- To emphasize certain moments
+- When strict meter feels too rigid
+- MUST still feel natural and rhythmic
+
+## Rhyme Schemes
+
+### AABB (Couplets)
+```
+The little red fox went out to play, (A)
+She ran through the forest all the day. (A)
+She jumped over logs and climbed up trees, (B)
+And chased the butterflies in the breeze. (B)
+```
+
+**Strengths:**
+- Simple, satisfying
+- Easy to follow
+- Quick resolution
+- Great for younger children (ages 2-5)
+
+**Weaknesses:**
+- Can feel predictable
+- May limit word choices
+
+### ABAB (Alternate)
+```
+The bear was looking for some honey, (A)
+He searched the forest high and low. (B)
+The bees thought this was rather funny— (A)
+They'd hidden it beneath the snow! (B)
+```
+
+**Strengths:**
+- More sophisticated
+- Delayed gratification
+- Builds anticipation
+- Good for ages 5-8
+
+**Weaknesses:**
+- Harder to maintain meter across 4 lines
+- Must keep rhyme words memorable
+
+### ABCB (Simple Ballad)
+```
+Max built a tower very tall (A)
+With blocks of every size. (B)
+He knew that it might crash and fall (A)
+But still he had to try. (B)
+```
+
+**Strengths:**
+- Less constrained than AABB
+- Natural speech patterns easier
+- Only need 2 rhymes per stanza
+- Sophisticated without being difficult
+
+**Weaknesses:**
+- Some readers expect more rhyme
+- Must make rhymes stand out
+
+### AABBA (Limerick)
+```
+There once was a dragon named Fred (A)
+Who painted his toenails bright red. (A)
+    He'd dance and he'd prance (B)
+    In a fancy pants dance (B)
+While wearing a crown on his head. (A)
+```
+
+**Strengths:**
+- Humorous rhythm
+- Very bouncy
+- Kids love the pattern
+- Great for silly stories
+
+**Weaknesses:**
+- Very specific meter required
+- Can feel limiting for serious themes
+- Best for short, funny pieces
+
+### AAAA (Monorhyme)
+```
+The cat sat on a mat so flat,
+She wore upon her head a hat,
+She saw a mouse (who was quite fat),
+And thought, "I'd like to catch that rat!"
+```
+
+**Strengths:**
+- Very simple for very young children
+- Strong rhythm reinforcement
+- Memorable
+
+**Weaknesses:**
+- Hard to maintain naturally
+- Can feel forced
+- Limited use cases
+
+## Rhyming Best Practices
+
+### Perfect Rhymes
+
+**Strong Perfect Rhymes:**
+```
+cat/hat/mat/sat/fat/bat/rat
+play/day/way/say/may/stay/bay
+moon/soon/tune/June/spoon/balloon
+bright/light/might/night/right/flight/tight/kite
+```
+
+**Use perfect rhymes when:**
+- Writing for younger children (ages 2-5)
+- You want strong, clear rhythm
+- The rhyme falls on an important word
+- Perfect rhyme comes naturally
+
+### Near Rhymes (Use Sparingly!)
+
+**Acceptable near rhymes:**
+```
+love/enough (when said quickly)
+again/ten
+orange/door-hinge (humorous, acknowledged)
+```
+
+**When near rhymes work:**
+- Better than forced perfect rhyme
+- On less emphasized words
+- When meter is perfect
+- In longer books where variety needed
+
+**NEVER:**
+- Use near rhyme on final, climactic rhyme
+- Rely on near rhyme throughout
+- Use near rhyme to avoid revising
+
+### Rhyme Position - Strong Words Only
+
+**WRONG:**
+```
+The elephant was really, really BIG
+And she liked to dance a funny JIG
+```
+(Emphasizes weak words: big, jig)
+
+**RIGHT:**
+```
+The elephant was gigantic, huge, IMMENSE
+Her dancing made the crowd grow very TENSE
+```
+(Emphasizes strong words: immense, tense)
+
+**Strong rhyme words:**
+- Nouns: bear, moon, star, friend
+- Verbs: run, jump, fly, dance
+- Adjectives: bright, small, brave, kind
+- Adverbs sparingly: away, today
+
+**Weak rhyme words to avoid:**
+- Articles: a, the
+- Prepositions: to, from, with
+- Weak verbs: was, is, are
+- Weak pronouns: it, that
+
+## Common Rhyming Pitfalls
+
+### 1. Forced Inversions
+
+**WRONG:**
+```
+The cat the mouse did see
+And chased it up the tree
+```
+(Unnatural word order: "the mouse did see")
+
+**RIGHT:**
+```
+The cat saw the mouse and gave a leap
+And chased it up the tree so steep
+```
+
+### 2. Padding with Filler Words
+
+**WRONG:**
+```
+The little tiny small young bear so brown
+Walked to the very big nearby large town
+```
+(Too many unnecessary adjectives)
+
+**RIGHT:**
+```
+The little bear with fur of brown
+Walked bravely toward the nearby town
+```
+
+### 3. Inconsistent Meter
+
+**WRONG:**
+```
+The DUCK walked DOWN the STREET one DAY (da-DUM-da-DUM-da-DUM-da-DUM) [4 beats]
+And she WAS feeling QUITE okay (da-da-DUM-da-DUM-DUM-da-DUM) [awkward, 3.5 beats]
+```
+
+**RIGHT:**
+```
+The DUCK walked DOWN the STREET one DAY (da-DUM-da-DUM-da-DUM-da-DUM) [4 beats]
+She WADDLED ALONG in her OWN special WAY (da-DUM-da-da-DUM-da-da-DUM-da-DUM) [4 beats]
+```
+
+### 4. Sacrificing Meaning for Rhyme
+
+**WRONG:**
+```
+Sarah loved to cook and bake
+Yesterday she made a rake
+```
+(Makes no sense - sacrificed meaning for rhyme)
+
+**RIGHT:**
+```
+Sarah loved to cook and bake
+Yesterday she made a cake
+```
+
+### 5. Overusing the Same Rhyme Sound
+
+**WRONG:**
+```
+The bear had hair everywhere
+On his chair, his underwear
+In the air, without a care
+```
+(Repetitive -air sound becomes boring)
+
+**RIGHT:**
+```
+The bear had fuzzy hair so brown
+The fluffiest fur in all the town
+It kept him warm when snow came down
+And earned him quite a royal crown
+```
+
+## Read-Aloud Testing
+
+### The Clap Test
+1. Clap or stomp to each stressed beat
+2. If you hesitate or stumble, revise
+3. Rhythm should feel completely natural
+
+### The Tongue-Twister Test
+1. Read your rhyme aloud 3 times fast
+2. If you trip up, it's too complicated
+3. Simplify word combinations
+
+### The Kid Test
+1. Read to an actual child if possible
+2. Watch where they lose interest
+3. Notice what makes them laugh or engage
+4. Revise accordingly
+
+### The Parent Test
+1. Parents read books 100+ times
+2. If it's annoying on repeat, revise
+3. Make it enjoyable for adult reader too
+
+## Advanced Techniques
+
+### Internal Rhyme
+```
+The cat in the hat sat on a mat
+And that is that, as a matter of fact!
+```
+
+**Effect:**
+- Adds musicality
+- Increases rhythm
+- Makes text memorable
+- Use sparingly to avoid overwhelming
+
+### Alliteration
+```
+Peter Penguin practiced prancing
+Perfectly, without a pause
+```
+
+**Effect:**
+- Musical quality
+- Fun to say aloud
+- Memorable
+- Don't overdo (sounds silly)
+
+### Assonance (Vowel Rhyme)
+```
+The fleet feet of the deer
+Moved swiftly, free and clear
+```
+
+**Effect:**
+- Subtle musicality
+- Sophisticated sound
+- Good for older readers (ages 7-9)
+
+### Consonance (Consonant Rhyme)
+```
+The duck struck luck
+When Chuck the truck
+Showed up
+```
+
+**Effect:**
+- Adds texture
+- Less obvious than perfect rhyme
+- Good for variety
+
+## Examples from Masters

+# Story Structures for Children's Books
+
+Proven narrative frameworks that create engaging, satisfying stories for young readers.
+
+## Basic Story Arc (All Ages)
+
+### The Universal Pattern
+
+```
+1. BEGINNING - Normal world, meet character
+2. INCITING INCIDENT - Problem appears
+3. RISING ACTION - Attempts to solve problem
+4. CLIMAX - Biggest challenge
+5. FALLING ACTION - Problem resolves
+6. RESOLUTION - New normal, lesson learned
+```
+
+**Applied to ages 2-3:**
+- Very simple problem
+- Immediate attempts
+- Quick resolution
+- Happy ending
+
+**Applied to ages 8-9:**
+- Complex problem
+- Multiple attempts
+- Character growth
+- Nuanced resolution
+
+## Age-Specific Structures
+
+### Ages 2-3: Simple Cause & Effect
+
+**Pattern:**
+```
+1. Character wants something
+2. Character tries to get it
+3. Character succeeds (or learns it's okay not to)
+```
+
+**Example: "Baby Bear's Honey"**
+```
+Page 1-2: Baby Bear is hungry. He wants honey.
+Page 3-4: He looks in the cupboard. No honey!
+Page 5-6: He looks under his bed. No honey!
+Page 7-8: He looks in the garden. No honey!
+Page 9-10: Mama Bear gives him honey. Yum!
+```
+
+**Key Elements:**
+- Repetition (looked three places)
+- Simple vocabulary
+- Clear cause and effect
+- Satisfying resolution
+- No complex emotions
+
+### Ages 3-5: The Rule of Three
+
+**Pattern:**
+```
+1. Problem appears
+2. First attempt (fails)
+3. Second attempt (fails)
+4. Third attempt (succeeds)
+5. Celebration
+```
+
+**Example: "Rosie's Too-Small Shoes"**
+```
+Setup: Rosie's favorite red shoes are too small!
+
+Attempt 1: She tries wiggling her toes. Doesn't work!
+Attempt 2: She tries pulling really hard. Doesn't work!
+Attempt 3: Mama says, "Let's get new shoes!"
+
+Resolution: Rosie gets new red shoes that fit perfectly!
+Lesson: Growing up means new things (shoes, adventures, etc.)
+```
+
+**Why Three Works:**
+- Pattern recognition for young minds
+- Not too short (boring) or too long (loses attention)
+- Rhythm: try, try, succeed
+- Builds anticipation
+
+### Ages 5-7: Problem-Solution with Character Growth
+
+**Pattern:**
+```
+1. Meet character with personality trait
+2. Problem that challenges that trait
+3. Character struggles (2-3 attempts)
+4. Character learns/grows
+5. Problem solved through growth
+6. New understanding
+```
+
+**Example: "Shy Sam Makes a Friend"**
+```
+Beginning: Sam is very shy. At recess, he always plays alone.
+
+Inciting Incident: A new kid, Alex, arrives at school.
+
+Rising Action:
+- Sam wants to say hi but is too nervous (internal conflict)
+- He watches Alex play alone
+- Sam's teacher encourages him: "Maybe Alex is nervous too?"
+
+Climax: Sam takes a deep breath and walks over. "Hi, I'm Sam."
+
+Resolution: Alex smiles! "I'm Alex. I'm nervous. Will you show me around?"
+
+Ending: Sam realizes everyone gets nervous sometimes. He made a friend by being brave!
+
+Lesson: Courage, empathy, friendship
+```
+
+**Key Elements:**
+- Internal conflict (shyness)
+- External conflict (making friends)
+- Relatable situation
+- Character growth (shy → brave)
+- Satisfying emotional payoff
+
+### Ages 7-9: Multi-Layered Plot
+
+**Pattern:**
+```
+1. Establish character, world, and desire
+2. Obstacle appears (external)
+3. Attempts to overcome obstacle reveal internal conflict
+4. Multiple failures, raising stakes
+5. Character must change to succeed
+6. Resolution addresses both external and internal conflict
+7. Character transformed
+```
+
+**Example: "Mira's Science Fair Disaster"**
+```
+Setup:
+- Mira loves science
+- She's usually the best in class
+- This makes her a bit overconfident
+- Science fair is coming up
+
+Inciting Incident:
+- Mira chooses an ambitious volcano project
+- She doesn't plan carefully (overconfidence)
+
+Rising Action:
+- First attempt: volcano doesn't erupt (she forgot baking soda)
+- She blames the instructions, doesn't take responsibility
+- Second attempt: makes a huge mess (used too much)
+- Best friend offers help, but Mira refuses (pride)
+- Third attempt fails spectacularly (day before fair)
+- Mira breaks down, admits she needs help
+
+Climax:
+- Friend helps her problem-solve
+- Together they figure it out
+- Mira realizes: asking for help isn't weakness
+
+Resolution:
+- Science fair: volcano works perfectly
+- Mira shares credit with friend
+- She doesn't win first place (unexpected!)
+- But she's happy because she learned teamwork
+
+Ending:
+- Mira still loves science
+- Now she also values collaboration
+- She's a better scientist AND friend
+
+Themes: Humility, collaboration, growth mindset, friendship
+```
+
+**Key Elements:**
+- Realistic problem
+- Character flaw (overconfidence)
+- Natural consequences
+- Emotional depth
+- Unexpected but satisfying resolution
+- Multiple lessons
+
+## Classic Children's Book Structures
+
+### 1. The Quest Journey
+
+**Pattern:**
+```
+Character must go somewhere or find something
+↓
+Journey with obstacles
+↓
+Each obstacle teaches something
+↓
+Character arrives/finds goal
+↓
+Realizes the journey was the real treasure
+```
+
+**Examples:**
+- We're Going on a Bear Hunt
+- The Little Engine That Could
+- Where the Wild Things Are (emotional journey)
+
+**Best for:** Ages 3-7
+**Teaches:** Perseverance, courage, growth
+
+**Template:**
+```
+Page 1-4: Character needs/wants something far away
+Page 5-8: Obstacle 1 (teaches lesson A)
+Page 9-12: Obstacle 2 (teaches lesson B)
+Page 13-16: Obstacle 3 (teaches lesson C)
+Page 17-20: Character reaches goal
+Page 21-24: Character realizes growth/journey's meaning
+```
+
+### 2. The "Day in the Life"
+
+**Pattern:**
+```
+Morning begins normally
+↓
+Small problem arises
+↓
+Problem compounds throughout day
+↓
+By evening, problem resolves naturally
+↓
+Bedtime/reflection
+```
+
+**Examples:**
+- Alexander and the Terrible, Horrible, No Good, Very Bad Day
+- The Snowy Day
+- Corduroy
+
+**Best for:** Ages 4-8
+**Teaches:** Everyday resilience, problem-solving, optimism
+
+**Template:**
+```
+Morning: Character wakes up, something unusual happens
+Breakfast: Problem becomes apparent
+Mid-day: Problem gets worse/funnier
+Afternoon: Character tries to fix problem
+Evening: Resolution (often natural or with help)
+Bedtime: Reflection, comfort, hope for tomorrow
+```
+
+### 3. The Cumulative Tale
+
+**Pattern:**
+```
+Element 1 introduced
+↓
+Element 2 added (1+2)
+↓
+Element 3 added (1+2+3)
+↓
+Pattern continues building
+↓
+Climax: everything comes together
+↓
+Reverse or resolution
+```
+
+**Examples:**
+- The House That Jack Built
+- There Was an Old Lady Who Swallowed a Fly
+- The Napping House
+
+**Best for:** Ages 2-5
+**Teaches:** Sequencing, memory, cause-effect
+
+**Template:**
+```
+"This is the [thing]."
+
+"This is the [thing2] that [verbed] the [thing1]."
+
+"This is the [thing3] that [verbed] the [thing2]
+that [verbed] the [thing1]."
+
+[Continue building]
+
+[Climax or reversal breaks the pattern]
+
+[Everything resolves in reverse or all at once]
+```
+
+### 4. The Circle Story
+
+**Pattern:**
+```
+Story begins and ends in the same place/situation
+↓
+But character/situation has changed
+↓
+Demonstrates growth through circular structure
+```
+
+**Examples:**
+- If You Give a Mouse a Cookie
+- The Runaway Bunny
+- Goodnight Moon (circular daily ritual)
+
+**Best for:** Ages 3-7
+**Teaches:** Cycles, comfort through repetition, growth
+
+**Template:**
+```
+Opening: Establish setting/situation
+Character leaves/changes/tries something new
+Adventures/experiences
+Character returns to original setting
+Ending: Same place, but transformed understanding
+```
+
+### 5. The Problem-Solver
+
+**Pattern:**
+```
+Character has a problem
+↓
+Tries creative solutions (usually 3)
+↓
+Solutions cause funny consequences
+↓
+Final solution works (often simple)
+↓
+Or: learns to accept the "problem"
+```
+
+**Examples:**
+- Cloudy With a Chance of Meatballs
+- The Dot (by Peter H. Reynolds)
+- Ish (by Peter H. Reynolds)
+
+**Best for:** Ages 5-9
+**Teaches:** Creativity, problem-solving, persistence
+
+**Template:**
+```
+Setup: Character faces problem
+Solution 1: Creative but flawed attempt (humorous consequence)
+Solution 2: Even more creative attempt (funnier consequence)
+Solution 3: Overblown attempt (funniest consequence)
+Resolution: Simple solution works OR acceptance is the answer
+```
+
+### 6. The Surprise Twist
+
+**Pattern:**
+```
+Story sets up expectation
+↓
+Builds on that expectation
+↓
+Unexpected reveal/twist
+↓
+Re-read value (clues were there!)
+```
+
+**Examples:**
+- The True Story of the Three Little Pigs (perspective twist)
+- Interrupting Chicken (meta twist)
+- The Day the Crayons Quit (personification twist)
+
+**Best for:** Ages 5-9
+**Teaches:** Perspective, critical thinking, humor
+
+**Template:**
+```
+Setup: Establish "normal" situation
+Build: Story progresses as expected
+Hint: Subtle clues something's different
+Twist: Reveal that changes everything
+Resolution: New understanding/humor
+```

+
+## Character Arc Structures
+
+### The Growth Arc (Most Common)
+
+```
+Character starts with flaw/fear
+↓
+Problem forces them to confront it
+↓
+They struggle, fail
+↓
+They learn and change
+↓
+They overcome problem through growth
+```
+
+**Example Arcs:**
+- Selfish → Generous
+- Fearful → Brave
+- Unkind → Kind
+- Impatient → Patient
+- Closed-minded → Open-minded
+
+### The Realization Arc
+
+```
+Character thinks they want X
+↓
+They pursue X
+↓
+They realize they actually need Y
+↓
+Pivot to Y
+↓
+Find true happiness
+```
+
+**Example:**
+- Wants to be popular → Realizes true friendship matters more
+- Wants to win → Realizes trying your best matters more
+- Wants to be big/strong → Realizes being yourself is best
+
+### The Impact Arc
+
+```
+Character is fine, but their world isn't
+↓
+They make a choice or take action
+↓
+Their action impacts others
+↓
+World changes for the better
+```
+
+**Example:**
+- Lonely kid reaches out → Others feel included
+- Creative kid makes art → Inspires whole class
+- Kind kid helps → Starts kindness chain
+
+## Dialogue Patterns
+
+### Ages 2-4: Simple, Repetitive
+
+```
+"Hello!" said the cat.
+"Hello!" said the dog.
+"Hello!" said the mouse.
+"Hello to everyone!" said the owl.
+```
+
+**Technique:**
+- Repetition of structure
+- Simple greetings/phrases
+- Predictable pattern
+- Easy to remember
+
+### Ages 5-7: Natural, Character-Driven
+
+```
+"I'm scared of the dark," whispered Maya.
+
+"Me too," said her teddy bear, Buttons.
+
+Maya looked at Buttons in surprise. "You can talk?"
+
+"Only when you need me," Buttons replied with a soft smile.
+```
+
+**Technique:**
+- Shows emotion through dialogue
+- Reveals character personality
+- Advances plot
+- Age-appropriate vocabulary
+- Magical realism
+
+### Ages 8-9: Distinct Voices
+
+```
+"We should definitely tell the teacher," said careful Chloe.
+
+"Are you kidding? We'd get in SO much trouble!" Jake rolled his eyes.
+
+Mia crossed her arms. "Or, hear me out, we could fix it ourselves."
+
+"Oh, this'll be good," Jake muttered.
+
+Chloe sighed. "Why do I feel like this is a terrible idea?"
+
+"Because," Mia grinned, "it absolutely is."
+```
+
+**Technique:**
+- Each character has unique voice
+- Subtext and personality
+- Humor through dialogue
+- Group dynamics
+- Realistic kid speech
+
+## Story Starters by Type
+
+### Adventure Stories
+```
+"The map showed an X right where [character]'s house was.
+This was going to be the best treasure hunt ever!"
+```
+
+### Friendship Stories
+```
+"[Character] had exactly zero friends.
+But that was about to change."
+```
+
+### Problem-Solving Stories
+```
+"When [character] woke up that morning,
+everything was [adjective].
+Including them."
+```
+
+### Emotion Stories
+```
+"[Character]'s [emotion] was so big,
+it filled the whole room.
+Maybe even the whole house.
+Possibly the whole world."
+```
+
+### Bedtime Stories
+```
+"As the stars began to twinkle in the sleepy sky,
+[character] settled down for the night..."
+```
+
+## Ending Techniques
+
+### The Full Circle
+```
+Beginning: "Every morning, Sophie looked out her window at the birds."
+Ending: "Every morning, Sophie looked out her window. But now, she flew with them."
+```
+
+### The Hope Forward
+```
+"Tomorrow, they'd have new adventures.
+But tonight? Tonight was perfect."
+```
+
+### The Quiet Resolution
+```
+"And as the moon rose high above,
+[character] finally understood:
+[lesson stated simply]."
+```
+
+### The Open Door
+```
+"But that's a story for another day..."
+```
+
+### The Celebration
+```
+"And they all [celebrated/danced/laughed/lived] happily ever after.
+Well, until the next adventure, anyway!"
+```
+
+## Common Structure Mistakes
+
+### ❌ No Clear Problem
+```
+Character does things, stuff happens, the end.
+```
+**Fix:** Establish clear goal or problem early
+
+### ❌ Too Many Problems
+```
+Character must save the world, make friends, learn math, and clean their room!
+```
+**Fix:** One main problem, one main lesson
+
+### ❌ Deus Ex Machina
+```
+Problem is huge and unsolvable... then magic fairy solves it!
+```
+**Fix:** Character must solve own problem (with support okay)
+
+### ❌ Rushed Resolution
+```
+30 pages of problem, 1 page resolution.
+```
+**Fix:** Balance build and payoff
+
+### ❌ No Stakes
+```
+Nothing matters, character isn't invested, reader isn't either.
+```
+**Fix:** Make readers care through emotional connection
+
+## Summary
+
+Effective children's book structures:
+- Have clear beginning, middle, end
+- Match complexity to age group
+- Use repetition and patterns for younger readers
+- Build character growth for older readers
+- Create satisfying resolution
+- Leave readers happy and thinking
+- Work on re-reading (find new details)
+
+**"Structure is the skeleton. Character is the heart. Your unique voice is the soul."**

+# Values and Themes for Children's Books
+
+Teaching positive values and important life lessons through engaging storytelling—showing, not telling.
+
+## Core Principle: Show, Don't Preach
+
+### ❌ Preachy (Telling)
+```
+"Remember, children, you should always be kind to others.
+Being kind is very important. You must be kind every day.
+The end."
+```
+
+**Why This Fails:**
+- Lectures the reader
+- No story
+- No character to relate to
+- No emotional connection
+- Boring and forgettable
+
+### ✅ Story-Driven (Showing)
+```
+Maya saw the new kid sitting alone at lunch.
+His lunch tray was empty—just a small apple.
+
+Maya looked at her own lunch. Sandwich, chips, cookies, juice.
+She had so much.
+
+Maya took a deep breath and walked over.
+"Hi, I'm Maya. Want to share my cookies?"
+
+The boy's face lit up. "Really? I'm Alex. Thanks!"
+
+As they ate together, Maya realized something:
+Sharing didn't make her cookies less special.
+It made them taste even better.
+```
+
+**Why This Works:**
+- Shows kindness in action
+- Character makes a choice
+- Natural consequence (friendship, good feeling)
+- Reader experiences the lesson through character
+- Memorable and emotionally resonant
+
+## Universal Values for Children's Books
+
+### 1. Kindness & Empathy
+
+**What It Teaches:**
+- Considering others' feelings
+- Helping those in need
+- Being inclusive
+- Treating others well
+
+**Story Framework:**
+```
+Character sees someone struggling/sad/alone
+↓
+Character has choice: ignore or help
+↓
+Character chooses kindness (maybe overcomes own discomfort)
+↓
+Positive outcome for both
+↓
+Character feels good, learns empathy
+```
+
+**Example Scenarios:**
+- Inviting lonely kid to play
+- Helping elderly neighbor
+- Being kind to someone different
+- Standing up for someone being teased
+- Sharing with someone who has less
+- Comforting a friend who's sad
+
+**Books That Do This Well:**
+- "Have You Filled a Bucket Today?" by Carol McCloud
+- "The Invisible Boy" by Trudy Ludwig
+- "Each Kindness" by Jacqueline Woodson
+
+**Sample Opening:**
+```
+Title: "Leo's Invisible Friend"
+
+Every day at recess, Leo played alone.
+He built sandcastles in the corner of the playground,
+far from the other kids.
+
+One day, Mia noticed him.
+Not just saw him—really noticed.
+
+She noticed how carefully he built each tower.
+She noticed how he smiled at his creation.
+She noticed he was all by himself.
+
+"Can I help?" Mia asked.
+
+Leo looked up, surprised. "You want to?"
+
+"Your castle needs a moat," Mia said, grabbing a shovel.
+
+By the end of recess, they'd built the best sandcastle ever.
+And Leo wasn't invisible anymore.
+```
+
+### 2. Courage & Bravery
+
+**What It Teaches:**
+- Trying despite fear
+- Standing up for yourself/others
+- Facing new challenges
+- Overcoming anxiety
+
+**Types of Courage:**
+- Physical (trying scary playground equipment)
+- Social (making first friend, public speaking)
+- Emotional (trying after failure)
+- Moral (standing up for what's right)
+
+**Story Framework:**
+```
+Character faces something scary/new
+↓
+Character feels fear (validating emotion)
+↓
+Character gets support/finds inner strength
+↓
+Character tries despite fear
+↓
+Outcome (success OR valuable lesson in trying)
+```
+
+**Example Scenarios:**
+- First day of school
+- Learning to swim/ride bike
+- Performing in front of others
+- Standing up to bully
+- Trying something after failing
+- Speaking up when something is wrong
+
+**Books That Do This Well:**
+- "Brave Irene" by William Steig
+- "The Kissing Hand" by Audrey Penn
+- "Jabari Jumps" by Gaia Cornwall
+
+**Sample Story:**
+```
+Title: "Mira's Big Voice"
+
+Mira had ideas. So many ideas!
+In her head, they were brilliant.
+But whenever she tried to share them in class...
+
+Nothing came out.
+
+Her voice got stuck somewhere between her brain and her mouth.
+
+"What if they laugh?" her worry whispered.
+"What if it's a bad idea?" her fear muttered.
+
+One day, her class was stuck on a problem.
+Nobody could figure out how to build a tall tower that wouldn't fall.
+
+Mira had the answer. She knew she did.
+
+Her hand shook as she raised it.
+Her voice wobbled as she spoke.
+
+"What if we... put the wide blocks on the bottom?"
+
+The room went quiet.
+
+Then her teacher smiled. "Mira, that's brilliant! Let's try it."
+
+It worked.
+
+Mira's voice was small, but her idea was BIG.
+And that's what mattered.
+```
+
+### 3. Honesty & Integrity
+
+**What It Teaches:**
+- Telling the truth even when hard
+- Admitting mistakes
+- Keeping promises
+- Doing the right thing
+
+**Story Framework:**
+```
+Character makes mistake or is tempted to lie
+↓
+Character faces choice: lie or tell truth
+↓
+Character sees consequences of dishonesty (if applicable)
+↓
+Character chooses honesty (or learns lesson)
+↓
+Natural consequences (usually relief, respect, trust)
+```
+
+**Example Scenarios:**
+- Breaking something and admitting it
+- Cheating temptation
+- Keeping a promise despite inconvenience
+- Returning found money/item
+- Admitting you don't know something
+- Taking responsibility for actions
+
+**Books That Do This Well:**
+- "The Empty Pot" by Demi
+- "A Big Fat Enormous Lie" by Marjorie Weinman Sharmat
+
+**Sample Story:**
+```
+Title: "The Cookie Jar Mystery"
+
+The cookie jar was empty.
+Completely, totally empty.
+
+"Who ate all the cookies?" Dad asked.
+
+Jake's little sister pointed at him. "Jake did it!"
+
+Jake opened his mouth to say "No, I didn't!"
+
+But that would be a lie.
+
+He HAD eaten the cookies. All six of them.
+His stomach still hurt, actually.
+
+"I... I did," Jake said quietly. "I'm sorry."
+
+He waited for Dad to be mad.
+
+Instead, Dad sighed. "Thank you for being honest.
+That took courage. But you know you were supposed to ask first."
+
+"I know," Jake said. "I'll help you bake more?"
+
+"Deal," Dad said. "Honesty makes everything better.
+Even when it's hard."
+
+Jake learned that day: Telling the truth might feel scary,
+but lying feels worse.
+```
+
+### 4. Perseverance & Growth Mindset
+
+**What It Teaches:**
+- Trying again after failure
+- Practice makes progress
+- Mistakes are learning opportunities
+- Effort matters more than immediate success
+
+**Story Framework:**
+```
+Character wants to achieve something
+↓
+First attempt fails
+↓
+Character feels frustrated/wants to quit
+↓
+Support/encouragement or self-reflection
+↓
+Character tries different approach
+↓
+Progress (not necessarily perfection)
+↓
+Character learns value of persistence
+```
+
+**Example Scenarios:**
+- Learning new skill (sport, instrument, art)
+- Difficult homework/school project
+- Making something (building, cooking, crafting)
+- Achieving personal goal
+- Overcoming obstacle
+
+**Books That Do This Well:**
+- "Rosie Revere, Engineer" by Andrea Beaty
+- "The Most Magnificent Thing" by Ashley Spires
+- "Ish" by Peter H. Reynolds
+- "The Dot" by Peter H. Reynolds
+
+**Sample Story:**
+```
+Title: "Zara's Wobbliest Bike Ride"
+
+Zara wanted to ride her bike without training wheels.
+
+Attempt #1: She fell before she even started. THUD.
+Attempt #2: She made it three feet. Then CRASH.
+Attempt #3: Five feet! Then BOOM.
+
+"I can't do this!" Zara yelled, throwing her helmet.
+
+Her big brother picked it up. "You're getting better.
+You went from zero feet to five feet. That's progress!"
+
+"But I keep falling," Zara said.
+
+"Yep. That's how you learn," he smiled.
+
+Attempt #4: Seven feet before falling.
+Attempt #5: Ten feet!
+Attempt #10: Zara made it to the end of the driveway.
+
+She fell. But she rode.
+
+"I did it!" she shouted.
+
+"You did," her brother said. "Because you kept trying."
+
+Falling wasn't failing, Zara learned.
+Giving up was.
+```
+
+### 5. Self-Acceptance & Confidence
+
+**What It Teaches:**
+- Being yourself is enough
+- Everyone is unique and special
+- Differences are valuable
+- Self-worth doesn't depend on others' opinions
+
+**Story Framework:**
+```
+Character feels different/inadequate
+↓
+Character tries to change to fit in OR feels bad
+↓

+
+The other penguins whispered.
+They pointed.
+They laughed.
+
+Penny tried to wash off the dots. They wouldn't budge.
+She tried to cover them with snow. It melted.
+She tried to hide. But you can't hide polka dots.
+
+One day, Penny's little brother got lost in a snowstorm.
+All the penguins looked the same in the white snow.
+
+But Penny?
+Her pink dots shone through the storm like beacons.
+
+Her brother saw the dots and found his way home.
+
+"Your dots saved him!" the penguins cheered.
+
+Penny looked at her polka dots differently that day.

+
+"Emma..." Mom gave her The Look.
+
+Fine. Emma invited Ava.
+
+On party day, Sophia got sick. She couldn't come.
+
+Emma's perfect party was ruined.
+
+Or... was it?
+
+Ava showed up with homemade friendship bracelets for everyone.
+She taught them a game from her old school.
+She even brought her dog, Biscuit, who did tricks!
+
+It wasn't the party Emma planned.
+It was better.

+Later, Emma called Sophia. "I miss you! But Ava is really nice.
+I think you'd like her too."
+
+"More friends are always better than fewer," Sophia said.

+## Theme Complexity by Age
+
+### Ages 2-4: Simple, Clear
+
+**Appropriate Themes:**
+- Sharing toys
+- Being kind to friends
+- Trying new foods
+- Bedtime routines
+- Basic emotions (happy, sad)
+
+**Keep It:**
+- Concrete
+- Immediate
+- Positive
+- Simple cause-effect
+
+### Ages 5-7: Expanding
+
+**Appropriate Themes:**
+- Making friends
+- First day experiences
+- Small fears
+- Being helpful
+- Learning new skills
+- Simple fairness
+
+**Can Include:**
+- Mild conflict (resolved)
+- More complex emotions
+- Character growth
+- Simple moral choices
+
+### Ages 8-9: Nuanced
+
+**Appropriate Themes:**
+- Complex friendships
+- Identity and belonging
+- Social issues (simplified)
+- Loss and change (appropriate)
+- Standing up for beliefs
+- Ethical dilemmas
+
+**Can Handle:**
+- Moral complexity
+- Multiple perspectives
+- Internal conflict
+- Longer character arcs
+- Realistic problems
+
+## Multi-Layered Themes
+
+**Best books teach multiple values:**
+
+**Example: "The Dandelion Wish"**
+```
+Primary theme: Self-acceptance
+Secondary themes:
+- Handling bullying (respect)
+- Finding your purpose (identity)
+- Kindness (the little girl)
+- Looking beneath surface (beauty in unexpected places)
+```
+
+## Avoiding Common Pitfalls
+
+### ❌ Too Preachy
+```
+"And so Timmy learned that sharing is good.
+Everyone should share.
+Always share.
+The end."
+```
+
+**Fix:** Let character discover through experience, not lecture.
+
+### ❌ Unrealistic Consequences
+```
+"Billy shared his toy, so he immediately got a new bike!"
+```
+
+**Fix:** Realistic, internal rewards (good feeling, friendship, pride)
+
+### ❌ Villain-izing
+```
+"The mean, horrible, terrible bully was sent away forever."
+```
+
+**Fix:** Show everyone can grow, change, and make better choices.
+
+### ❌ Adult Problems
+```
+Story about divorce, death, serious illness without age-appropriate handling
+```
+
+**Fix:** Match complexity to age, focus on child's experience and resilience
+
+### ❌ No Stakes
+```
+"Everything was perfect. Everyone was happy. The end."
+```
+
+**Fix:** Include realistic challenge that character must overcome
+
+## Diverse & Inclusive Themes
+
+### Representation Matters
+
+**Include:**
+- Different family structures
+- Various cultural backgrounds
+- Different abilities
+- Range of body types
+- Gender diversity
+- Economic diversity
+
+**Authenticity:**
+- Research lived experiences
+- Avoid stereotypes
+- Consult sensitivity readers
+- Normalize diversity (not always "the lesson")
+
+### Universal Themes, Specific Characters
+
+**Good approach:**
+```
+Universal theme: Belonging
+Specific character: Child of immigrant parents navigating two cultures
+Result: Specific, authentic story that resonates universally
+```
+
+## Values Worksheet
+
+**Before writing, identify:**
+
+1. **Primary Value:** What's the main lesson?
+2. **Character Flaw:** What does character need to learn?
+3. **Story Problem:** How does problem relate to value?
+4. **Character Choice:** Where does character choose lesson?
+5. **Natural Consequence:** What happens because of choice?
+6. **Emotional Payoff:** How does character (and reader) feel?
+
+## Summary
+
+Effective value-teaching in children's books:
+- Shows values through action, not lectures
+- Creates relatable characters facing real challenges
+- Allows characters to make choices
+- Includes natural consequences
+- Provides emotional payoff
+- Age-appropriate complexity
+- Respects young readers' intelligence
+- Leaves readers thinking and feeling
+
+**"The best children's books don't teach lessons—they offer experiences that help children discover lessons for themselves."**

+# Data Structures Reference
+
+Essential data structures for technical interviews with implementation patterns.
+
+## Arrays
+
+**Use when:** Sequential data, random access needed
+**Time:** Access O(1), Search O(n), Insert/Delete O(n)
+**Space:** O(n)
+
+### Common Patterns
+```python
+# Reverse
+arr[::-1]
+
+# Two pointers
+left, right = 0, len(arr) - 1
+
+# Sliding window
+for end in range(len(arr)):
+    window.add(arr[end])
+    if end >= k:
+        window.remove(arr[end - k])
+```
+
+### Product Example: Instagram Feed
+```python
+class InstagramFeed:
+    def __init__(self):
+        self.posts = []  # Array of posts
+
+    def add_post(self, post):
+        self.posts.insert(0, post)  # New posts at beginning
+
+    def get_feed(self, start, limit):
+        return self.posts[start:start + limit]
+```
+
+## Hash Maps
+
+**Use when:** Fast lookups, counting, caching
+**Time:** O(1) average for all operations
+**Space:** O(n)
+
+### Common Patterns
+```python
+# Frequency counter
+freq = {}
+for item in items:
+    freq[item] = freq.get(item, 0) + 1
+
+# Two sum
+seen = {}
+for i, num in enumerate(nums):
+    complement = target - num
+    if complement in seen:
+        return [seen[complement], i]
+    seen[num] = i
+```
+
+### Product Example: Twitter Hashtags
+```python
+class TrendingHashtags:
+    def __init__(self):
+        self.hashtag_count = {}
+
+    def process_tweet(self, tweet):
+        for hashtag in tweet.hashtags:
+            self.hashtag_count[hashtag] = \
+                self.hashtag_count.get(hashtag, 0) + 1
+
+    def get_trending(self, k):
+        return sorted(self.hashtag_count.items(),
+                     key=lambda x: x[1], reverse=True)[:k]
+```
+
+## Linked Lists
+
+**Use when:** Frequent insertions/deletions, unknown size
+**Time:** Access O(n), Insert/Delete O(1) at known position
+**Space:** O(n)
+
+### Common Patterns
+```python
+# Fast & slow pointers (detect cycle)
+slow = fast = head
+while fast and fast.next:
+    slow = slow.next
+    fast = fast.next.next
+    if slow == fast:
+        return True
+
+# Reverse linked list
+prev = None
+curr = head
+while curr:
+    next_node = curr.next
+    curr.next = prev
+    prev = curr
+    curr = next_node
+```
+
+### Product Example: Browser History
+```python
+class BrowserHistory:
+    def __init__(self):
+        self.current = None
+
+    def visit(self, url):
+        new_page = Page(url)
+        new_page.prev = self.current
+        if self.current:
+            self.current.next = new_page
+        self.current = new_page
+
+    def back(self):
+        if self.current and self.current.prev:
+            self.current = self.current.prev
+        return self.current.url
+
+    def forward(self):
+        if self.current and self.current.next:
+            self.current = self.current.next
+        return self.current.url
+```
+
+## Stacks
+
+**Use when:** LIFO, backtracking, parsing
+**Time:** O(1) for push/pop
+**Space:** O(n)
+
+### Common Patterns
+```python
+# Valid parentheses
+stack = []
+pairs = {'(': ')', '[': ']', '{': '}'}
+
+for char in s:
+    if char in pairs:
+        stack.append(char)
+    elif not stack or pairs[stack.pop()] != char:
+        return False
+
+return len(stack) == 0
+```
+
+### Product Example: Code Editor Undo/Redo
+```python
+class CodeEditor:
+    def __init__(self):
+        self.undo_stack = []
+        self.redo_stack = []
+        self.content = ""
+
+    def type(self, text):
+        self.undo_stack.append(self.content)
+        self.content += text
+        self.redo_stack.clear()
+
+    def undo(self):
+        if self.undo_stack:
+            self.redo_stack.append(self.content)
+            self.content = self.undo_stack.pop()
+
+    def redo(self):
+        if self.redo_stack:
+            self.undo_stack.append(self.content)
+            self.content = self.redo_stack.pop()
+```
+
+## Queues
+
+**Use when:** FIFO, BFS, scheduling
+**Time:** O(1) for enqueue/dequeue
+**Space:** O(n)
+
+### Common Patterns
+```python
+from collections import deque
+
+# BFS
+queue = deque([start])
+visited = {start}
+
+while queue:
+    node = queue.popleft()
+    for neighbor in node.neighbors:
+        if neighbor not in visited:
+            visited.add(neighbor)
+            queue.append(neighbor)
+```
+
+### Product Example: Uber Request Queue
+```python
+from collections import deque
+
+class UberQueue:
+    def __init__(self):
+        self.requests = deque()
+
+    def add_request(self, rider, location):
+        self.requests.append({
+            'rider': rider,
+            'location': location,
+            'timestamp': time.time()
+        })
+
+    def match_driver(self, driver):
+        if self.requests:
+            request = self.requests.popleft()
+            return request
+        return None
+```
+
+## Heaps (Priority Queues)
+
+**Use when:** Top K, median, scheduling by priority
+**Time:** O(log n) insert/delete, O(1) peek
+**Space:** O(n)
+
+### Common Patterns
+```python
+import heapq
+
+# Top K elements (min heap)
+min_heap = []
+for num in nums:
+    heapq.heappush(min_heap, num)
+    if len(min_heap) > k:
+        heapq.heappop(min_heap)
+
+# K closest points (max heap with negation)
+max_heap = []
+for point in points:
+    dist = -distance(point)  # Negative for max heap
+    heapq.heappush(max_heap, (dist, point))
+    if len(max_heap) > k:
+        heapq.heappop(max_heap)
+```
+
+### Product Example: Uber Driver Matching
+```python
+import heapq
+
+class UberMatching:
+    def __init__(self):
+        self.available_drivers = []  # Min heap by distance
+
+    def add_driver(self, driver, distance):
+        heapq.heappush(self.available_drivers, (distance, driver))
+
+    def match_closest_driver(self):
+        if self.available_drivers:
+            distance, driver = heapq.heappop(self.available_drivers)
+            return driver
+        return None
+```
+
+## Trees (Binary Trees)
+
+**Use when:** Hierarchical data, BST operations
+**Time:** O(log n) balanced, O(n) worst case
+**Space:** O(h) for recursion
+
+### Common Patterns
+```python
+# Inorder traversal (DFS)
+def inorder(root):
+    if not root:
+        return []
+    return inorder(root.left) + [root.val] + inorder(root.right)
+
+# Level order (BFS)
+def levelOrder(root):
+    if not root:
+        return []
+    result, queue = [], deque([root])
+    while queue:
+        level = []

+            if node.right: queue.append(node.right)
+        result.append(level)
+    return result
+```
+
+### Product Example: File System

+        self.root = Directory("/")
+
+    def create_path(self, path):

+
+## Graphs
+
+**Use when:** Networks, relationships, dependencies
+**Time:** BFS/DFS O(V + E)
+**Space:** O(V + E) for adjacency list
+
+### Common Patterns
+```python
+# Adjacency list representation
+graph = {
+    'A': ['B', 'C'],
+    'B': ['D'],
+    'C': ['D'],
+    'D': []
+}
+
+# DFS
+def dfs(node, visited=set()):
+    if node in visited:
+        return
+    visited.add(node)
+    for neighbor in graph[node]:
+        dfs(neighbor, visited)
+
+# BFS
+def bfs(start):
+    visited = {start}
+    queue = deque([start])
+    while queue:
+        node = queue.popleft()
+        for neighbor in graph[node]:
+            if neighbor not in visited:
+                visited.add(neighbor)
+                queue.append(neighbor)
+```
+
+### Product Example: Social Network
+```python
+class SocialNetwork:
+    def __init__(self):
+        self.friends = {}  # user_id -> [friend_ids]
+
+    def add_friendship(self, user1, user2):
+        if user1 not in self.friends:
+            self.friends[user1] = []
+        if user2 not in self.friends:
+            self.friends[user2] = []
+
+        self.friends[user1].append(user2)
+        self.friends[user2].append(user1)
+
+    def degrees_of_separation(self, user1, user2):
+        """BFS to find shortest path"""
+        if user1 == user2:
+            return 0
+
+        visited = {user1}
+        queue = deque([(user1, 0)])
+
+        while queue:
+            current, degree = queue.popleft()
+
+            for friend in self.friends.get(current, []):

+                    queue.append((friend, degree + 1))
+
+        return -1  # Not connected
+```
+
+## Tries (Prefix Trees)
+
+**Use when:** Autocomplete, prefix matching, dictionary
+**Time:** O(m) for word length m
+**Space:** O(ALPHABET_SIZE * m * n)
+
+### Common Patterns
+```python
+class TrieNode:
+    def __init__(self):
+        self.children = {}

+
+class Trie:
+    def __init__(self):
+        self.root = TrieNode()
+
+    def insert(self, word):
+        node = self.root
+        for char in word:
+            if char not in node.children:
+                node.children[char] = TrieNode()

+    def __init__(self):
+        self.trie = Trie()
+        self.word_frequency = {}
+
+    def add_search(self, query):
+        self.trie.insert(query)
+        self.word_frequency[query] = \
+            self.word_frequency.get(query, 0) + 1
+
+    def get_suggestions(self, prefix):
+        suggestions = []
+
+        def dfs(node, current_word):
+            if node.is_end:
+                suggestions.append(current_word)
+
+            for char, child_node in node.children.items():
+                dfs(child_node, current_word + char)
+
+        # Find prefix node
+        node = self.trie.root
+        for char in prefix:
+            if char not in node.children:
+                return []
+            node = node.children[char]
+
+        # DFS from prefix node
+        dfs(node, prefix)
+
+        # Sort by frequency

+# LeetCode Patterns Reference
+
+The 20 essential coding patterns for technical interviews with templates and real product examples.
+
+## Pattern 1: Two Pointers
+
+**When to Use:** Find pairs, triplets, or process sorted arrays
+**Time:** O(n), **Space:** O(1)
+
+### Template (Python)
+```python
+def two_pointers(arr):
+    left, right = 0, len(arr) - 1
+
+    while left < right:
+        # Process current pair
+        if condition:
+            # Found solution
+            return [left, right]
+        elif arr[left] + arr[right] < target:
+            left += 1
+        else:
+            right -= 1
+
+    return []
+```
+
+### Real Example: Instagram Mutual Likes
+```python
+def find_mutual_likes(user_ids, target_sum):
+    """Find two users whose IDs sum to target"""
+    left, right = 0, len(user_ids) - 1
+
+    while left < right:
+        current_sum = user_ids[left] + user_ids[right]
+
+        if current_sum == target_sum:
+            return [left, right]
+        elif current_sum < target_sum:
+            left += 1
+        else:
+            right -= 1
+
+    return []
+```
+
+## Pattern 2: Sliding Window
+
+**When to Use:** Find subarray/substring with property
+**Time:** O(n), **Space:** O(k)
+
+### Template (Python)
+```python
+def sliding_window(arr, k):
+    window_start = 0
+    max_sum = 0
+    window_sum = 0
+
+    for window_end in range(len(arr)):
+        window_sum += arr[window_end]
+
+        if window_end >= k - 1:
+            max_sum = max(max_sum, window_sum)
+            window_sum -= arr[window_start]
+            window_start += 1
+
+    return max_sum
+```
+
+### Real Example: Twitter Trending Topics
+```python
+def trending_in_window(tweets, time_window):
+    """Find most mentioned hashtag in time window"""
+    hashtag_count = {}
+    max_count = 0
+    trending = ""
+
+    for i, tweet in enumerate(tweets):
+        # Add new tweet
+        if tweet.hashtag in hashtag_count:
+            hashtag_count[tweet.hashtag] += 1
+        else:
+            hashtag_count[tweet.hashtag] = 1
+
+        # Remove old tweets outside window
+        if i >= time_window:
+            old_tag = tweets[i - time_window].hashtag
+            hashtag_count[old_tag] -= 1
+            if hashtag_count[old_tag] == 0:
+                del hashtag_count[old_tag]
+
+        # Track max
+        for tag, count in hashtag_count.items():
+            if count > max_count:
+                max_count = count
+                trending = tag
+
+    return trending
+```
+
+## Pattern 3: Fast & Slow Pointers
+
+**When to Use:** Detect cycles, find middle element
+**Time:** O(n), **Space:** O(1)
+
+### Template (Python)
+```python
+def has_cycle(head):
+    slow = fast = head
+
+    while fast and fast.next:
+        slow = slow.next
+        fast = fast.next.next
+
+        if slow == fast:
+            return True
+
+    return False
+```
+
+### Real Example: Package Manager Circular Dependency
+```python
+def detect_circular_dependency(package):
+    """Detect if package has circular dependencies"""
+    slow = fast = package
+
+    while fast and fast.next_dependency:
+        slow = slow.next_dependency
+        fast = fast.next_dependency.next_dependency
+
+        if slow == fast:
+            return True  # Circular dependency found!
+
+    return False
+```
+
+## Pattern 4: Merge Intervals
+
+**When to Use:** Overlapping intervals, scheduling
+**Time:** O(n log n), **Space:** O(n)
+
+### Template (Python)
+```python
+def merge_intervals(intervals):
+    if not intervals:
+        return []
+
+    intervals.sort(key=lambda x: x[0])
+    merged = [intervals[0]]
+
+    for current in intervals[1:]:
+        last = merged[-1]
+
+        if current[0] <= last[1]:
+            # Overlapping, merge
+            merged[-1] = [last[0], max(last[1], current[1])]
+        else:
+            # Non-overlapping
+            merged.append(current)
+
+    return merged
+```
+
+### Real Example: Google Calendar Free Slots
+```python
+def find_free_slots(calendars, duration):
+    """Find free meeting slots for all attendees"""
+    # Merge all busy times
+    busy = []
+    for calendar in calendars:
+        busy.extend(calendar.busy_times)
+
+    busy.sort()
+    merged_busy = merge_intervals(busy)
+
+    # Find gaps >= duration
+    free_slots = []
+    for i in range(len(merged_busy) - 1):
+        gap_start = merged_busy[i][1]
+        gap_end = merged_busy[i + 1][0]
+
+        if gap_end - gap_start >= duration:
+            free_slots.append([gap_start, gap_end])
+
+    return free_slots
+```
+
+## Pattern 5: Binary Search (Modified)
+
+**When to Use:** Search in O(log n), find boundary
+**Time:** O(log n), **Space:** O(1)
+
+### Template (Python)
+```python
+def binary_search_modified(arr, target):
+    left, right = 0, len(arr) - 1
+
+    while left <= right:
+        mid = (left + right) // 2
+
+        if arr[mid] == target:
+            return mid
+        elif arr[mid] < target:
+            left = mid + 1
+        else:
+            right = mid - 1
+
+    return -1
+```
+
+### Real Example: GitHub Find Bug Introduction Version
+```python
+def find_first_bad_version(versions):
+    """Binary search to find when bug was introduced"""
+    left, right = 0, len(versions) - 1
+    first_bad = -1
+
+    while left <= right:
+        mid = (left + right) // 2
+
+        if is_bad_version(versions[mid]):
+            first_bad = mid
+            right = mid - 1  # Look for earlier bad version
+        else:
+            left = mid + 1
+
+    return first_bad
+```
+
+## Pattern 6: Top K Elements
+
+**When to Use:** Find top/bottom K items
+**Time:** O(n log k), **Space:** O(k)
+
+### Template (Python)
+```python
+import heapq
+
+def top_k_elements(nums, k):
+    # Min heap of size k
+    min_heap = []
+
+    for num in nums:
+        heapq.heappush(min_heap, num)
+
+        if len(min_heap) > k:
+            heapq.heappop(min_heap)
+
+    return min_heap
+```
+
+### Real Example: Reddit Top Posts
+```python
+def get_top_k_posts(posts, k):
+    """Get top K posts by upvotes"""
+    min_heap = []
+
+    for post in posts:
+        heapq.heappush(min_heap, (post.upvotes, post))
+
+        if len(min_heap) > k:
+            heapq.heappop(min_heap)
+
+    return [post for (upvotes, post) in sorted(min_heap, reverse=True)]
+```
+
+## Pattern 7: BFS (Breadth-First Search)
+
+**When to Use:** Shortest path, level-order traversal
+**Time:** O(V + E), **Space:** O(V)
+
+### Template (Python)
+```python
+from collections import deque
+
+def bfs(root):
+    if not root:
+        return []
+
+    result = []
+    queue = deque([root])
+
+    while queue:
+        level_size = len(queue)
+
+        for _ in range(level_size):
+            node = queue.popleft()
+            result.append(node.val)
+
+            if node.left:
+                queue.append(node.left)
+            if node.right:
+                queue.append(node.right)
+
+    return result
+```
+
+### Real Example: LinkedIn Degrees of Connection
+```python
+def degrees_of_connection(user1, user2):
+    """Find shortest connection path between users"""
+    if user1 == user2:
+        return 0
+
+    visited = {user1}
+    queue = deque([(user1, 0)])
+
+    while queue:
+        current_user, degree = queue.popleft()
+
+        for connection in current_user.connections:
+            if connection == user2:
+                return degree + 1
+
+            if connection not in visited:
+                visited.add(connection)
+                queue.append((connection, degree + 1))
+
+    return -1  # Not connected
+```
+
+## Pattern 8: DFS (Depth-First Search)
+
+**When to Use:** Path finding, backtracking
+**Time:** O(V + E), **Space:** O(V)
+
+### Template (Python)
+```python
+def dfs(node, visited=None):
+    if visited is None:
+        visited = set()
+
+    if node in visited:
+        return
+
+    visited.add(node)
+    process(node)
+
+    for neighbor in node.neighbors:
+        dfs(neighbor, visited)
+
+    return visited
+```
+
+### Real Example: File System Path Finding
+```python
+def find_all_paths(start_dir, target_file):
+    """Find all paths to target file"""
+    paths = []
+
+    def dfs(current_dir, path):
+        if current_dir.name == target_file:
+            paths.append(path + [current_dir.name])
+            return
+
+        for subdir in current_dir.subdirectories:
+            dfs(subdir, path + [current_dir.name])
+
+    dfs(start_dir, [])
+    return paths
+```
+
+## Pattern 9: Dynamic Programming
+
+**When to Use:** Optimization, counting problems
+**Time:** Varies (often O(n²)), **Space:** O(n) or O(n²)
+
+### Template (Python)
+```python
+def dp_solution(n):
+    # Initialize DP array
+    dp = [0] * (n + 1)
+    dp[0] = base_case
+
+    # Fill DP array
+    for i in range(1, n + 1):
+        dp[i] = transition(dp[i-1], dp[i-2], ...)
+
+    return dp[n]
+```
+
+### Real Example: Minimum Venmo Transactions
+```python
+def min_transactions(debts):
+    """Minimum transactions to settle all debts"""
+    # Calculate net balance for each person
+    balance = {}
+    for payer, payee, amount in debts:
+        balance[payer] = balance.get(payer, 0) - amount
+        balance[payee] = balance.get(payee, 0) + amount
+
+    # Remove zero balances
+    amounts = [v for v in balance.values() if v != 0]
+
+    def dfs(idx):
+        # Skip settled accounts
+        while idx < len(amounts) and amounts[idx] == 0:
+            idx += 1
+
+        if idx == len(amounts):
+            return 0
+
+        min_trans = float('inf')
+
+        for i in range(idx + 1, len(amounts)):
+            # Try settling idx with i
+            if amounts[idx] * amounts[i] < 0:  # Different signs
+                amounts[i] += amounts[idx]
+                min_trans = min(min_trans, 1 + dfs(idx + 1))
+                amounts[i] -= amounts[idx]  # Backtrack
+
+        return min_trans
+
+    return dfs(0)
+```
+
+## Pattern 10: Backtracking
+
+**When to Use:** Generate all combinations, permutations
+**Time:** Exponential, **Space:** O(n)
+
+### Template (Python)
+```python
+def backtrack(path, choices):
+    if is_solution(path):
+        result.append(path[:])
+        return
+
+    for choice in choices:
+        # Make choice
+        path.append(choice)
+
+        # Recurse
+        backtrack(path, remaining_choices)
+
+        # Undo choice (backtrack)
+        path.pop()
+```
+
+### Real Example: Slack Channel Combinations
+```python
+def generate_team_combinations(members, team_size):
+    """Generate all possible teams of given size"""
+    teams = []
+
+    def backtrack(start, current_team):
+        if len(current_team) == team_size:
+            teams.append(current_team[:])
+            return
+
+        for i in range(start, len(members)):
+            current_team.append(members[i])
+            backtrack(i + 1, current_team)
+            current_team.pop()
+
+    backtrack(0, [])
+    return teams
+```

+1. **Recognition**: "I've seen this pattern before"
+2. **Template**: "I know the code structure"
+3. **Adaptation**: "I can modify for this specific problem"
+4. **Optimization**: "I can improve time/space complexity"
+
+Practice each pattern 5-10 times until it becomes second nature!

+description: This skill should be used when users want to route LLM requests to different AI providers (OpenAI, Grok/xAI, Groq, DeepSeek, OpenRouter) using SwiftOpenAI-CLI. Use this skill when users ask to "use grok", "ask grok", "use groq", "ask deepseek", or any similar request to query a specific LLM provider in agent mode.
+---
+
+# LLM Router
+
+## Overview
+
+Route AI requests to different LLM providers using SwiftOpenAI-CLI's agent mode. This skill automatically configures the CLI to use the requested provider (OpenAI, Grok, Groq, DeepSeek, or OpenRouter), ensures the tool is installed and up-to-date, and executes one-shot agentic tasks.
+
+## Core Workflow
+
+When a user requests to use a specific LLM provider (e.g., "use grok to explain quantum computing"), follow this workflow:
+
+### Step 1: Ensure SwiftOpenAI-CLI is Ready
+
+Check if SwiftOpenAI-CLI is installed and up-to-date:
+
+```bash
+scripts/check_install_cli.sh
+```
+
+This script will:
+- Check if `swiftopenai` is installed
+- Verify the version (minimum 1.4.4)
+- Install or update if necessary
+- Report the current installation status
+
+### Step 2: Configure the Provider
+
+Based on the user's request, identify the target provider and configure SwiftOpenAI-CLI:
+
+```bash
+scripts/configure_provider.sh <provider> [model]
+```
+
+**Supported providers:**
+- `openai` - OpenAI (GPT-4, GPT-5, etc.)
+- `grok` - xAI Grok models
+- `groq` - Groq (Llama, Mixtral, etc.)
+- `deepseek` - DeepSeek models
+- `openrouter` - OpenRouter (300+ models)
+
+**Examples:**
+
+```bash
+# Configure for Grok
+scripts/configure_provider.sh grok grok-4-0709
+
+# Configure for Groq with Llama
+scripts/configure_provider.sh groq llama-3.3-70b-versatile
+
+# Configure for DeepSeek Reasoner
+scripts/configure_provider.sh deepseek deepseek-reasoner
+
+# Configure for OpenAI GPT-5
+scripts/configure_provider.sh openai gpt-5
+```
+
+The script automatically:
+- Sets the provider configuration
+- Sets the appropriate base URL
+- Sets the default model
+- Provides guidance on API key configuration
+
+### Step 3: Verify API Key
+
+The configuration script automatically checks if an API key is set and will **stop with clear instructions** if no API key is found.
+
+**If API key is missing:**
+
+The script exits with error code 1 and displays:
+- ⚠️ Warning that API key is not set
+- Instructions for setting via environment variable
+- Instructions for setting via config (persistent)
+
+**Do not proceed to Step 4 if the configuration script fails due to missing API key.**
+
+Instead, inform the user they need to set their API key first:
+
+**Option 1 - Environment variable (session only):**
+```bash
+export XAI_API_KEY=xai-...           # for Grok
+export GROQ_API_KEY=gsk_...          # for Groq
+export DEEPSEEK_API_KEY=sk-...       # for DeepSeek
+export OPENROUTER_API_KEY=sk-or-...  # for OpenRouter
+export OPENAI_API_KEY=sk-...         # for OpenAI
+```
+
+**Option 2 - Config file (persistent):**
+```bash
+swiftopenai config set api-key <api-key-value>
+```
+
+After the user sets their API key, re-run the configuration script to verify.
+
+### Step 4: Execute the Agentic Task
+
+Run the user's request using agent mode:
+
+```bash
+swiftopenai agent "<user's question or task>"
+```
+
+**Agent mode features:**
+- One-shot task execution
+- Built-in tool calling
+- MCP (Model Context Protocol) integration support
+- Conversation memory with session IDs
+- Multiple output formats
+
+**Examples:**
+
+```bash
+# Simple question
+swiftopenai agent "What is quantum entanglement?"
+
+# With specific model override
+swiftopenai agent "Write a Python function" --model grok-3
+
+# With session for conversation continuity
+swiftopenai agent "Remember my name is Alice" --session-id chat-123
+swiftopenai agent "What's my name?" --session-id chat-123
+
+# With MCP tools (filesystem example)
+swiftopenai agent "Read the README.md file" \
+  --mcp-servers filesystem \
+  --allowed-tools "mcp__filesystem__*"
+```
+
+## Usage Patterns
+
+### Pattern 1: Simple Provider Routing
+
+**User Request:** "Use grok to explain quantum computing"
+
+**Execution:**
+
+```bash
+# 1. Check CLI installation
+scripts/check_install_cli.sh
+
+# 2. Configure for Grok
+scripts/configure_provider.sh grok grok-4-0709
+
+# 3. Execute the task
+swiftopenai agent "Explain quantum computing"
+```
+
+### Pattern 2: Specific Model Selection
+
+**User Request:** "Ask DeepSeek Reasoner to solve this math problem step by step"
+
+**Execution:**
+
+```bash
+# 1. Check CLI installation
+scripts/check_install_cli.sh
+
+# 2. Configure for DeepSeek with Reasoner model
+scripts/configure_provider.sh deepseek deepseek-reasoner
+
+# 3. Execute with explicit model
+swiftopenai agent "Solve x^2 + 5x + 6 = 0 step by step" --model deepseek-reasoner
+```
+
+### Pattern 3: Fast Inference with Groq
+
+**User Request:** "Use groq to generate code quickly"
+
+**Execution:**
+
+```bash
+# 1. Check CLI installation
+scripts/check_install_cli.sh
+
+# 2. Configure for Groq (known for fast inference)
+scripts/configure_provider.sh groq llama-3.3-70b-versatile
+
+# 3. Execute the task
+swiftopenai agent "Write a function to calculate fibonacci numbers"
+```
+
+### Pattern 4: Access Multiple Models via OpenRouter
+
+**User Request:** "Use OpenRouter to access Claude"
+
+**Execution:**
+
+```bash
+# 1. Check CLI installation
+scripts/check_install_cli.sh
+
+# 2. Configure for OpenRouter
+scripts/configure_provider.sh openrouter anthropic/claude-3.5-sonnet
+
+# 3. Execute with Claude via OpenRouter
+swiftopenai agent "Explain the benefits of functional programming"
+```
+
+## Provider-Specific Considerations
+
+### OpenAI (GPT-5 Models)
+
+GPT-5 models support advanced parameters:
+
+```bash
+# Minimal reasoning for fast coding tasks
+swiftopenai agent "Write a sort function" \
+  --model gpt-5 \
+  --reasoning minimal \
+  --verbose low
+
+# High reasoning for complex problems
+swiftopenai agent "Explain quantum mechanics" \
+  --model gpt-5 \
+  --reasoning high \
+  --verbose high
+```
+
+**Verbosity levels:** `low`, `medium`, `high`
+**Reasoning effort:** `minimal`, `low`, `medium`, `high`
+
+### Grok (xAI)
+
+Grok models are optimized for real-time information and coding:
+
+- `grok-4-0709` - Latest with enhanced reasoning
+- `grok-3` - General purpose
+- `grok-code-fast-1` - Optimized for code generation
+
+### Groq
+
+Known for ultra-fast inference with open-source models:
+
+- `llama-3.3-70b-versatile` - Best general purpose
+- `mixtral-8x7b-32768` - Mixture of experts
+
+### DeepSeek
+
+Specialized in reasoning and coding:
+
+- `deepseek-reasoner` - Advanced step-by-step reasoning
+- `deepseek-coder` - Coding specialist
+- `deepseek-chat` - General chat
+
+### OpenRouter
+
+Provides access to 300+ models:
+
+- Anthropic Claude models
+- OpenAI models
+- Google Gemini models
+- Meta Llama models
+- And many more
+
+## API Key Management
+
+### Recommended: Use Environment Variables for Multiple Providers
+
+The **best practice** for using multiple providers is to set all API keys as environment variables. This allows seamless switching between providers without reconfiguring keys.
+
+**Add to your shell profile** (`~/.zshrc` or `~/.bashrc`):
+
+```bash
+# API Keys for LLM Providers
+export OPENAI_API_KEY=sk-...
+export XAI_API_KEY=xai-...
+export GROQ_API_KEY=gsk_...
+export DEEPSEEK_API_KEY=sk-...
+export OPENROUTER_API_KEY=sk-or-v1-...
+```
+
+After adding these, reload your shell:
+
+```bash
+source ~/.zshrc  # or source ~/.bashrc
+```
+
+**How it works:**
+- SwiftOpenAI-CLI automatically uses the **correct provider-specific key** based on the configured provider
+- When you switch to Grok, it uses `XAI_API_KEY`
+- When you switch to OpenAI, it uses `OPENAI_API_KEY`
+- No need to reconfigure keys each time
+
+### Alternative: Single API Key via Config (Not Recommended for Multiple Providers)
+
+If you only use **one provider**, you can store the key in the config file:
+
+```bash
+swiftopenai config set api-key <your-key>
+```
+
+**Limitation:** The config file only stores ONE api-key. If you switch providers, you'd need to reconfigure the key each time.
+
+### Checking Current API Key
+
+```bash
+# View current configuration (API key is masked)
+swiftopenai config list
+
+# Get specific API key setting
+swiftopenai config get api-key
+```
+
+**Priority:** Provider-specific environment variables take precedence over config file settings.
+
+## Advanced Features
+
+### Interactive Configuration
+
+For complex setups, use the interactive wizard:
+
+```bash
+swiftopenai config setup
+```
+
+This launches a guided setup that walks through:
+- Provider selection
+- API key entry
+- Model selection
+- Debug mode configuration
+- Base URL setup (if needed)
+
+### Session Management
+
+Maintain conversation context across multiple requests:
+
+```bash
+# Start a session
+swiftopenai agent "My project is a React app" --session-id project-123
+
+# Continue the session
+swiftopenai agent "What framework did I mention?" --session-id project-123
+```
+
+### MCP Tool Integration
+
+Connect to external services via Model Context Protocol:
+
+```bash
+# With GitHub MCP
+swiftopenai agent "List my repos" \
+  --mcp-servers github \
+  --allowed-tools "mcp__github__*"
+
+# With filesystem MCP
+swiftopenai agent "Read package.json and explain dependencies" \
+  --mcp-servers filesystem \
+  --allowed-tools "mcp__filesystem__*"
+
+# Multiple MCP servers
+swiftopenai agent "Complex task" \
+  --mcp-servers github,filesystem,postgres \
+  --allowed-tools "mcp__*"
+```
+
+### Output Formats
+
+Control how results are presented:
+
+```bash
+# Plain text (default)
+swiftopenai agent "Calculate 5 + 3" --output-format plain
+
+# Structured JSON
+swiftopenai agent "List 3 colors" --output-format json
+
+# Streaming JSON events (Claude SDK style)
+swiftopenai agent "Analyze data" --output-format stream-json
+```
+
+## Troubleshooting
+
+### Common Issues
+
+**Issue: "swiftopenai: command not found"**
+
+Solution: Run the check_install_cli.sh script, which will install the CLI automatically.
+
+**Issue: Authentication errors**
+
+Solution: Verify the correct API key is set for the provider:
+
+```bash
+# Check current config
+swiftopenai config list
+
+# Set the appropriate API key
+swiftopenai config set api-key <your-key>
+
+# Or use environment variable
+export XAI_API_KEY=xai-...  # for Grok
+```
+
+**Issue: Model not available**
+
+Solution: Verify the model name matches the provider's available models. Check `references/providers.md` for correct model names or run:
+
+```bash
+swiftopenai models
+```
+
+**Issue: Rate limiting or quota errors**
+
+Solution: These are provider-specific limits. Consider:
+- Using a different model tier
+- Switching to a different provider temporarily
+- Checking your API usage dashboard
+
+### Debug Mode
+
+Enable debug mode to see detailed HTTP information:
+
+```bash
+swiftopenai config set debug true
+```
+
+This shows:
+- HTTP status codes and headers
+- API request details
+- Response metadata
+
+## Resources
+
+This skill includes bundled resources to support LLM routing:
+
+### scripts/
+
+- **check_install_cli.sh** - Ensures SwiftOpenAI-CLI is installed and up-to-date
+- **configure_provider.sh** - Configures the CLI for a specific provider
+
+### references/
+
+- **providers.md** - Comprehensive reference on all supported providers, models, configurations, and capabilities
+
+## Best Practices
+
+1. **Always check installation first** - Run `check_install_cli.sh` before routing requests
+2. **Configure provider explicitly** - Use `configure_provider.sh` to ensure correct setup
+3. **Verify API keys** - Check that the appropriate API key is set for the target provider
+4. **Choose the right model** - Match the model to the task (coding, reasoning, general chat)
+5. **Use sessions for continuity** - Leverage `--session-id` for multi-turn conversations
+6. **Enable debug mode for troubleshooting** - When issues arise, debug mode provides valuable insights
+7. **Reference provider documentation** - Consult `references/providers.md` for detailed provider information
+

+```
+
+## Managing Multiple Provider API Keys
+
+### Best Practice: Use Provider-Specific Environment Variables
+
+To seamlessly use multiple providers without constantly reconfiguring API keys, set all provider keys as environment variables in your shell profile.
+
+**Add to `~/.zshrc` or `~/.bashrc`:**
+
+```bash
+# API Keys for LLM Providers
+export OPENAI_API_KEY=sk-...
+export XAI_API_KEY=xai-...
+export GROQ_API_KEY=gsk_...
+export DEEPSEEK_API_KEY=sk-...
+export OPENROUTER_API_KEY=sk-or-v1-...
+```
+
+**Benefits:**
+- ✅ All keys available at once
+- ✅ Automatic key selection based on provider
+- ✅ No need to reconfigure when switching providers
+- ✅ Keys persist across terminal sessions
+- ✅ More secure than storing in config file
+
+**After adding, reload your shell:**
+```bash
+source ~/.zshrc  # or source ~/.bashrc
+```
+
+### How SwiftOpenAI-CLI Selects API Keys
+
+When you configure a provider, SwiftOpenAI-CLI uses this priority:
+
+1. **Provider-specific environment variable** (e.g., `XAI_API_KEY` for Grok)
+2. Config file `api-key` setting (if set)
+3. Generic `OPENAI_API_KEY` fallback (for OpenAI provider only)
+
+**Example Flow:**
+```bash
+# Configure for Grok
+swiftopenai config set provider xai
+
+# CLI automatically uses XAI_API_KEY environment variable
+swiftopenai agent "Hello, world!"
+
+# Switch to OpenAI
+swiftopenai config set provider ""
+
+# CLI automatically uses OPENAI_API_KEY environment variable
+swiftopenai agent "Hello, world!"
+```
+
+### Config File Limitation
+
+The config file (`~/.swiftopenai/config.json`) only stores **ONE** api-key value. If you use `swiftopenai config set api-key <key>`, it will be used for **all providers** (unless overridden by a provider-specific env var).
+
+This is why environment variables are recommended for multiple providers.
+
+## Debug Mode
+
+Enable debug mode to see HTTP details:
+
+```bash
+swiftopenai config set debug true
+```
+
+Shows:
+- HTTP status codes and headers
+- Full API requests (when built in debug mode)
+- Response details
+
+## Troubleshooting
+
+### Authentication Errors
+
+- Verify API key is set correctly
+- Check environment variable is exported
+- Ensure provider configuration matches your API key
+
+### Model Not Available
+
+- Verify model name is correct for the provider
+- Use `swiftopenai models` to list available models
+- Check provider documentation for model availability
+
+### Connection Issues
+
+- Verify base URL is correct
+- Check network connectivity
+- Ensure API service is operational

+## Reference Materials
+
+All included in `/references`:
+- **basic_math.md** - Elementary concepts and techniques
+- **algebra.md** - Algebraic patterns and formulas
+- **geometry.md** - Geometric principles and visualizations
+- **calculus.md** - Derivatives, integrals, limits
+- **statistics.md** - Probability and data analysis
+- **gamification.md** - Game mechanics and reward systems
+
+## Scripts
+
+All in `/scripts`:
+- **generate_playground.sh** - Create interactive math playground
+- **generate_game.sh** - Build gamified math challenge
+- **generate_quiz.sh** - Create adaptive quiz system
+
+## Implementation Approach
+
+**IMPORTANT:** When this skill is invoked, use the Bash tool to execute the appropriate script.
+
+### How to use the scripts:
+
+1. **For general math games/challenges:** Use `generate_game.sh`
+   ```bash
+   bash /Users/jamesrochabrun/Desktop/skills/skills/math-teacher/scripts/generate_game.sh
+   ```
+
+2. **For interactive playgrounds:** Use `generate_playground.sh`
+   ```bash
+   bash /Users/jamesrochabrun/Desktop/skills/skills/math-teacher/scripts/generate_playground.sh
+   ```
+
+3. **For quizzes:** Use `generate_quiz.sh` (if it exists)
+   ```bash
+   bash /Users/jamesrochabrun/Desktop/skills/skills/math-teacher/scripts/generate_quiz.sh
+   ```
+
+**DO NOT** try to invoke these scripts automatically when the skill loads - this causes bash security errors. Always use the Bash tool explicitly to run them.
+
+## Best Practices
+
+### DO:
+✅ Make it visual and interactive
+✅ Start simple, add complexity gradually
+✅ Use colors and animations
+✅ Provide immediate feedback
+✅ Celebrate successes
+✅ Include hints and explanations
+✅ Make it fun and playful
+✅ Support mobile devices
+
+### DON'T:
+❌ Show just formulas without context
+❌ Make it text-heavy
+❌ Assume prior knowledge
+❌ Skip the gamification
+❌ Ignore visual learners
+❌ Make it intimidating
+❌ Use boring, academic tone
+❌ Require external libraries
+
+## Example Interactions

+
+# OpenAI Prompt Engineer
+
+A comprehensive skill for crafting, analyzing, and improving prompts for OpenAI's GPT-5 and other modern Large Language Models (LLMs), with focus on GPT-5-specific optimizations and universal prompting techniques.
+
+## What This Skill Does
+
+Helps you create and optimize prompts using cutting-edge techniques:
+- **Generate new prompts** - Build effective prompts from scratch
+- **Improve existing prompts** - Enhance clarity, structure, and results
+- **Apply best practices** - Use proven techniques for each model
+- **Optimize for specific models** - GPT-5, Claude-specific strategies
+- **Implement advanced patterns** - Chain-of-thought, few-shot, structured prompting
+- **Analyze prompt quality** - Identify issues and suggest improvements
+
+## Why Prompt Engineering Matters
+
+**Without good prompts:**
+- Inconsistent or incorrect outputs
+- Poor instruction following
+- Wasted tokens and API costs
+- Multiple attempts needed
+- Unpredictable behavior
+
+**With optimized prompts:**
+- Accurate, consistent results
+- Better instruction adherence
+- Lower costs and latency
+- First-try success
+- Predictable, reliable outputs
+
+## Supported Models & Approaches
+
+### GPT-5 (OpenAI)
+- Structured prompting (role + task + constraints)
+- Reasoning effort calibration
+- Agentic behavior control
+- Verbosity management
+- Prompt optimizer integration
+
+### Claude (Anthropic)
+- XML tag structuring
+- Step-by-step thinking
+- Clear, specific instructions
+- Example-driven prompting
+- Progressive disclosure
+
+### Universal Techniques
+- Chain-of-thought prompting
+- Few-shot learning
+- Zero-shot prompting
+- Self-consistency
+- Role-based prompting
+
+## Core Prompting Principles
+
+### 1. Be Clear and Specific
+**Bad:** "Write about AI"
+**Good:** "Write a 500-word technical article explaining transformer architecture for software engineers with 2-3 years of experience. Include code examples in Python and focus on practical implementation."
+
+### 2. Provide Structure
+Use clear formatting to organize instructions:
+```
+Role: You are a senior Python developer
+Task: Review this code for security vulnerabilities
+Constraints:
+- Focus on OWASP Top 10
+- Provide specific line numbers
+- Suggest fixes with code examples
+Output format: Markdown with severity ratings
+```
+
+### 3. Use Examples (Few-Shot)
+Show the model what you want:
+```
+Input: "User clicked login"
+Output: "USER_LOGIN_CLICKED"
+
+Input: "Payment processed successfully"
+Output: "PAYMENT_PROCESSED_SUCCESS"
+
+Input: "Email verification failed"
+Output: [Your turn]
+```
+
+### 4. Enable Reasoning
+Add phrases like:
+- "Think step-by-step"
+- "Let's break this down"
+- "First, analyze... then..."
+- "Show your reasoning"
+
+### 5. Define Output Format
+Specify exactly how you want the response:
+```xml
+<output_format>
+  <summary>One sentence overview</summary>
+  <details>
+    <point>Key finding 1</point>
+    <point>Key finding 2</point>
+  </details>
+  <recommendation>Specific action to take</recommendation>
+</output_format>
+```
+
+## Prompt Engineering Workflow
+
+### 1. Define Your Goal
+- What task are you solving?
+- What's the ideal output?
+- Who's the audience?
+- What model will you use?
+
+### 2. Choose Your Technique
+- **Simple task?** → Direct instruction
+- **Complex reasoning?** → Chain-of-thought
+- **Pattern matching?** → Few-shot examples
+- **Need consistency?** → Structured format + examples
+
+### 3. Build Your Prompt
+Use this template:
+```
+[ROLE/CONTEXT]
+You are [specific role with relevant expertise]
+
+[TASK]
+[Clear, specific task description]
+
+[CONSTRAINTS]
+- [Limitation 1]
+- [Limitation 2]
+
+[FORMAT]
+Output should be [exact format specification]
+
+[EXAMPLES - if using few-shot]
+[Example 1]
+[Example 2]
+
+[THINK STEP-BY-STEP - if complex reasoning]
+Before answering, [thinking instruction]
+```
+
+### 4. Test and Iterate
+- Run the prompt
+- Analyze output quality
+- Identify issues
+- Refine and retry
+- Document what works
+
+## Advanced Techniques
+
+### Chain-of-Thought (CoT) Prompting
+
+**When to use:** Complex reasoning, math, multi-step problems
+
+**How it works:** Ask the model to show intermediate steps
+
+**Example:**
+```
+Problem: A store has 15 apples. They sell 60% in the morning and
+half of what's left in the afternoon. How many remain?
+
+Please solve this step-by-step:
+1. Calculate morning sales
+2. Calculate remaining after morning
+3. Calculate afternoon sales
+4. Calculate final remaining
+```
+
+**Result:** More accurate answers through explicit reasoning
+
+### Few-Shot Prompting
+
+**When to use:** Pattern matching, classification, style transfer
+
+**How it works:** Provide 2-5 examples, then the actual task
+
+**Example:**
+```
+Convert casual text to professional business tone:
+
+Input: "Hey! Thanks for reaching out. Let's chat soon!"
+Output: "Thank you for your message. I look forward to our conversation."
+
+Input: "That's a great idea! I'm totally on board with this."
+Output: "I appreciate your suggestion and fully support this initiative."
+
+Input: "Sounds good, catch you later!"
+Output: [Model completes]
+```
+
+### Zero-Shot Chain-of-Thought
+
+**When to use:** Complex problems without examples
+
+**How it works:** Simply add "Let's think step by step"
+
+**Example:**
+```
+Question: What are the security implications of storing JWTs
+in localStorage?
+
+Let's think step by step:
+```
+
+**Magic phrase:** "Let's think step by step" → dramatically improves reasoning
+
+### Structured Output with XML
+
+**When to use:** Working with Claude or need parsed output
+
+**Example:**
+```
+Analyze this code for issues. Structure your response as:
+
+<analysis>
+  <security_issues>
+    <issue severity="high|medium|low">
+      <description>What's wrong</description>
+      <location>File and line number</location>
+      <fix>How to fix it</fix>
+    </issue>
+  </security_issues>
+  <performance_issues>
+    <!-- Same structure -->
+  </performance_issues>
+  <best_practices>
+    <suggestion>Improvement suggestion</suggestion>
+  </best_practices>
+</analysis>
+```
+
+### Progressive Disclosure
+
+**When to use:** Large context, multi-step workflows
+
+**How it works:** Break tasks into stages, only request what's needed now
+
+**Example:**
+```
+Stage 1: "Analyze this codebase structure and list the main components"
+[Get response]
+
+Stage 2: "Now, for the authentication component you identified,
+show me the security review"
+[Get response]
+
+Stage 3: "Based on that review, generate fixes for the high-severity issues"
+```
+
+## Model-Specific Best Practices
+
+### GPT-5 Optimization
+
+**Structured Prompting:**
+```
+ROLE: Senior TypeScript Developer
+TASK: Implement user authentication service
+CONSTRAINTS:
+- Use JWT with refresh tokens
+- TypeScript with strict mode
+- Include comprehensive error handling
+- Follow SOLID principles
+OUTPUT: Complete TypeScript class with JSDoc comments
+REASONING_EFFORT: high (for complex business logic)
+```
+
+**Control Agentic Behavior:**
+```
+"Implement this feature step-by-step, asking for confirmation
+before each major decision"
+
+OR
+
+"Complete this task end-to-end without asking for guidance.
+Persist until fully handled."
+```
+
+**Manage Verbosity:**
+```
+"Provide a concise implementation (under 100 lines) focusing
+only on core functionality"
+```
+
+### Claude Optimization
+
+**Use XML Tags:**
+```
+<instruction>
+Review this pull request for security issues
+</instruction>
+
+<code>
+[Code to review]
+</code>
+
+<focus_areas>
+- SQL injection vulnerabilities
+- XSS attack vectors
+- Authentication bypasses
+- Data exposure risks
+</focus_areas>
+
+<output_format>
+For each issue found, provide:
+1. Severity (Critical/High/Medium/Low)
+2. Location
+3. Explanation
+4. Fix recommendation
+</output_format>
+```
+
+**Step-by-Step Thinking:**
+```
+Think through this architecture decision step by step:
+1. First, identify the requirements
+2. Then, list possible approaches
+3. Evaluate trade-offs for each
+4. Make a recommendation with reasoning
+```
+
+**Clear Specificity:**
+```
+BAD: "Make the response professional"
+GOOD: "Use formal business language, avoid contractions,
+address the user as 'you', keep sentences under 20 words"
+```
+

+# Claude-Specific Techniques
+
+## Overview
+
+Claude (by Anthropic) excels at instruction following, long-context tasks, and detailed analysis. This guide covers techniques optimized specifically for Claude, based on official Anthropic documentation and best practices.
+
+## Claude's Strengths
+
+### What Claude Does Best
+
+1. **Instruction adherence** - Exceptional at following complex, detailed instructions
+2. **Long context** - Handles 100K+ tokens effectively
+3. **Structured output** - Excels with XML and structured formats
+4. **Safety and helpfulness** - Well-calibrated for harmless, helpful responses
+5. **Analysis depth** - Thorough analysis when asked
+6. **Reasoning clarity** - Shows work step-by-step naturally
+
+### Key Differentiators
+
+**Claude vs GPT-5:**
+- Better with very long contexts (200K vs GPT-5's limits)
+- More conservative (less likely to make things up)
+- Responds better to XML structuring
+- Excellent at detailed instruction following
+- Strong at nuanced analysis
+
+## XML Tag Structuring
+
+### Why XML Tags Matter
+
+Claude was trained with XML tags extensively, making them highly effective for:
+- Separating different types of content
+- Creating clear structure
+- Guiding output format
+- Organizing complex prompts
+
+### Basic XML Pattern
+
+```xml
+<instruction>
+Your main task description
+</instruction>
+
+<context>
+Background information Claude needs
+</context>
+
+<constraints>
+- Limitation 1
+- Limitation 2
+</constraints>
+
+<output_format>
+Expected structure of the response
+</output_format>
+```
+
+### Common Tag Names
+
+**Use these for clarity:**
+
+- `<instruction>` - Main task
+- `<context>` - Background info
+- `<examples>` - Sample inputs/outputs
+- `<constraints>` - Limitations
+- `<output_format>` - Desired structure
+- `<data>` - Data to process
+- `<document>` - Long-form content
+- `<code>` - Code snippets
+- `<thinking>` - Request reasoning steps
+
+**Example:**
+```xml
+<instruction>
+Review this code for security vulnerabilities
+</instruction>
+
+<code>
+function login(username, password) {
+  const query = `SELECT * FROM users WHERE username='${username}'`;
+  // ... more code
+}
+</code>
+
+<focus_areas>
+- SQL injection
+- Password handling
+- Session management
+</focus_areas>
+
+<output_format>
+For each issue:
+- Severity: Critical/High/Medium/Low
+- Location: Line number
+- Problem: Description
+- Fix: Recommended solution
+</output_format>
+```
+
+## Step-by-Step Thinking
+
+### Enabling Reasoning
+
+Claude naturally shows reasoning when asked, but you can enhance it:
+
+**Simple approach:**
+```
+Think step-by-step about this problem:
+
+[Problem description]
+```
+
+**Structured approach:**
+```xml
+<instruction>
+Solve this problem by thinking through it step-by-step
+</instruction>
+
+<problem>
+[Problem description]
+</problem>
+
+<thinking_process>
+1. First, identify the key components
+2. Then, analyze relationships
+3. Next, consider edge cases
+4. Finally, provide solution
+</thinking_process>
+```
+
+**Explicit reasoning request:**
+```
+Before providing your answer, explain your reasoning process.
+
+<thinking>
+[Let Claude show its work here]
+</thinking>
+
+<answer>
+[Then provide the final answer here]
+</answer>
+```
+
+### Benefits
+
+- More accurate results
+- Visible logic for debugging
+- Builds trust in responses
+- Helps Claude catch its own errors
+- Better for complex problems
+
+## Clear and Specific Instructions
+
+### The Clarity Principle
+
+**Treat Claude like a skilled intern on day one:**
+- Provide ALL necessary context
+- Define terms explicitly
+- Give specific examples
+- State assumptions clearly
+- Specify exact requirements
+
+### Bad vs Good Instructions
+
+**❌ Vague:**
+```
+"Make this better"
+```
+
+**✅ Specific:**
+```
+"Refactor this function to:
+1. Reduce cyclomatic complexity below 5
+2. Extract helper functions for clarity
+3. Add type annotations
+4. Include JSDoc comments
+5. Handle null/undefined edge cases"
+```
+
+**❌ Ambiguous:**
+```
+"Write professional content"
+```
+
+**✅ Explicit:**
+```
+"Write in formal business tone with these characteristics:
+- No contractions (use 'do not' vs 'don't')
+- Active voice
+- Sentences under 20 words
+- Direct address ('you') rather than third person
+- Industry-standard terminology
+- Professional but approachable"
+```
+
+### Specificity Checklist
+
+- [ ] Exact task clearly stated
+- [ ] Output format specified
+- [ ] Length/size requirements defined
+- [ ] Tone/style described
+- [ ] Edge cases addressed
+- [ ] Success criteria stated
+- [ ] Examples provided (if applicable)
+- [ ] Constraints listed
+
+## Progressive Disclosure
+
+### Why It Matters for Claude
+
+With Claude's 100K+ token context window, you might be tempted to dump everything at once. Don't.
+
+**Progressive disclosure benefits:**
+- More focused responses
+- Better token efficiency
+- Clearer reasoning chains
+- Easier to course-correct
+- More maintainable conversations
+
+### Pattern: Multi-Stage Workflow
+
+**Stage 1: High-level analysis**
+```xml
+<instruction>
+Analyze this codebase structure and provide:
+1. List of main components
+2. Key dependencies
+3. Overall architecture pattern
+</instruction>
+
+<codebase>
+[File structure]
+</codebase>
+```
+
+**Stage 2: Focused deep-dive**
+```xml
+<instruction>
+Now, for the authentication component you identified,
+perform a detailed security review
+</instruction>
+
+<context>
+You previously identified the auth component at: [location]
+</context>
+
+<focus>
+Review for:
+- Authentication bypass vulnerabilities
+- Token security
+- Session management
+- Password handling
+</focus>
+```
+
+**Stage 3: Implementation**
+```xml
+<instruction>
+Based on the security issues you found, implement fixes
+for the high-severity items
+</instruction>
+
+<issues_to_fix>
+[High severity issues from previous response]
+</issues_to_fix>
+```
+
+### When to Use Progressive Disclosure
+
+**Good for:**
+- Large codebases
+- Multi-step workflows
+- Research tasks
+- Iterative refinement
+- Complex projects
+
+**Not needed for:**
+- Simple, single-shot tasks
+- Well-defined transformations
+- When all context fits easily
+
+## Example-Driven Prompting
+
+### Few-Shot with Claude
+
+Claude excels at learning from examples. Show 2-5 examples of desired behavior:
+
+```xml
+<instruction>
+Convert casual messages to professional email format
+</instruction>
+
+<examples>
+<example>
+<input>
+Hey! Got your message. That sounds cool, let's do it!

+- Unrealistic/contrived
+- Missing edge cases
+- Inconsistent format
+
+## Long-Context Best Practices
+
+### Leveraging Claude's 100K+ Token Window
+
+Claude can handle massive context, but structure it well:
+
+```xml
+<task>
+Analyze all these customer support tickets for common issues
+</task>
+
+<tickets>
+<ticket id="1">
+[Ticket 1 content]
+</ticket>
+
+<ticket id="2">
+[Ticket 2 content]
+</ticket>
+
+<!-- ... many more tickets ... -->
+
+<ticket id="1523">
+[Ticket 1523 content]
+</ticket>
+</tickets>
+
+<analysis_instructions>
+1. Categorize issues by type
+2. Identify the top 5 most common problems
+3. Calculate frequency for each
+4. Recommend solutions for top issues
+5. Note any patterns across tickets
+</analysis_instructions>
+
+<output_format>
+## Issue Categories
+[List of categories found]
+
+## Top 5 Issues
+1. [Issue]: [Frequency] - [Description]
+   - Recommended solution: [Solution]
+
+## Patterns Observed
+[Cross-ticket patterns]
+</output_format>
+```
+
+### Long-Context Tips
+
+1. **Use clear delimiters** - XML tags, markdown headers
+2. **Structure hierarchically** - Group related content
+3. **Reference by ID** - Make it easy to cite specific parts
+4. **Summarize upfront** - Give Claude the big picture first
+5. **Be specific in queries** - Don't make Claude search the entire context
+
+## Document Analysis Pattern
+
+### For Large Documents
+
+```xml
+<instruction>
+Analyze this technical specification document
+</instruction>
+
+<document>
+[Large technical document - can be 50K+ tokens]
+</document>
+
+<analysis_framework>
+1. COMPLETENESS: Are all necessary sections present?
+2. CLARITY: Are requirements unambiguous?
+3. CONSISTENCY: Any contradictions?
+4. FEASIBILITY: Any technical concerns?
+5. GAPS: What's missing?
+</analysis_framework>
+
+<output_format>
+For each framework dimension:
+## [Dimension]
+- Assessment: [Good/Needs Work/Critical Issues]
+- Findings: [Specific findings with section references]
+- Recommendations: [What to improve]
+</output_format>
+```
+
+## Code Review Pattern
+
+### Thorough Code Analysis
+
+```xml
+<instruction>
+Conduct a comprehensive code review
+</instruction>
+
+<code_files>
+<file path="auth/service.ts">
+[Code content]
+</file>
+
+<file path="auth/controller.ts">
+[Code content]
+</file>
+
+<file path="auth/middleware.ts">
+[Code content]
+</file>
+</code_files>
+
+<review_criteria>
+<security>
+- Authentication/authorization flaws
+- Input validation
+- Sensitive data exposure
+- Injection vulnerabilities
+</security>
+
+<quality>
+- Code complexity
+- Naming conventions
+- DRY violations
+- Error handling
+</quality>
+
+<performance>
+- N+1 queries
+- Unnecessary loops
+- Inefficient algorithms
+</performance>
+</review_criteria>
+
+<output_format>
+For each issue found:
+### [Issue Title]
+- **Severity**: Critical/High/Medium/Low
+- **Category**: Security/Quality/Performance
+- **Location**: `[file]:[line]`
+- **Problem**: [Clear description]
+- **Impact**: [Why this matters]
+- **Fix**: [Specific code solution]
+
+At the end:
+### Summary
+- Total issues: [count by severity]
+- Recommendation: Approve / Request Changes / Comment
+- Must-fix before merge: [Critical/High issues]
+</output_format>
+```
+
+## Iterative Refinement Pattern
+
+### Building Complex Solutions
+
+**Round 1: Initial Draft**
+```xml
+<instruction>
+Create an initial draft of a REST API design for user management
+</instruction>
+
+<requirements>
+- CRUD operations for users
+- Authentication required
+- Role-based permissions
+- Email verification flow
+</requirements>
+```
+
+**Round 2: Refine Based on Feedback**
+```xml
+<instruction>
+Refine the API design based on this feedback
+</instruction>
+
+<original_design>
+[Claude's previous response]
+</original_design>
+
+<feedback>
+- Add rate limiting specifications
+- Include pagination for list endpoints
+- Define error response format
+- Add API versioning strategy
+</feedback>
+```
+
+**Round 3: Implementation Details**
+```xml
+<instruction>
+Now provide implementation details for the refined design
+</instruction>
+
+<context>
+Refined API design: [design from round 2]
+</context>
+
+<implementation_requirements>
+- TypeScript with Express
+- PostgreSQL database
+- JWT authentication
+- Include OpenAPI spec
+</implementation_requirements>
+```
+
+## Structured Output Enforcement
+
+### Guaranteed Format with XML
+
+```xml
+<instruction>
+Analyze this data and respond ONLY in the specified XML format
+</instruction>
+
+<data>
+[Data to analyze]
+</data>
+
+<required_output_format>
+<analysis>
+  <summary>One paragraph overview</summary>
+  <metrics>
+    <metric name="[name]" value="[value]" trend="up|down|stable"/>
+    <!-- Repeat for each metric -->
+  </metrics>
+  <insights>
+    <insight priority="high|medium|low">
+      <finding>What was discovered</finding>
+      <implication>What it means</implication>
+      <action>What to do</action>
+    </insight>
+    <!-- Repeat for each insight -->
+  </insights>
+</analysis>
+</required_output_format>
+
+Do not include any text outside this XML structure.
+```
+
+## Common Claude Patterns
+
+### Pattern 1: Document Summarization
+
+```xml
+<instruction>
+Summarize this document for [target audience]
+</instruction>
+
+<document>
+[Long document]
+</document>
+
+<summary_requirements>
+- Length: [word count]
+- Focus: [key aspects]
+- Include: [specific elements]
+- Tone: [formal/casual/technical]
+</summary_requirements>
+
+<output_structure>
+1. Executive Summary (2-3 sentences)
+2. Key Points (bullet list)
+3. Important Details (1-2 paragraphs)
+4. Action Items (if applicable)
+</output_structure>
+```
+
+### Pattern 2: Data Extraction
+
+```xml
+<instruction>
+Extract structured data from these unstructured documents
+</instruction>
+
+<documents>
+<document id="1">
+[Unstructured text]
+</document>
+<!-- More documents -->
+</documents>
+
+<extraction_schema>
+{
+  "name": "string",
+  "date": "YYYY-MM-DD",
+  "amount": "number",
+  "category": "string",
+  "tags": ["string"]
+}
+</extraction_schema>
+
+<output_format>
+Return a JSON array of objects matching the schema
+</output_format>
+```
+
+### Pattern 3: Comparative Analysis
+
+```xml
+<instruction>
+Compare these options across the specified dimensions
+</instruction>
+
+<options>
+<option name="Option A">
+[Details]
+</option>
+
+<option name="Option B">
+[Details]
+</option>
+
+<option name="Option C">
+[Details]
+</option>
+</options>
+
+<comparison_dimensions>
+- Cost (initial and ongoing)
+- Performance (speed, scalability)
+- Complexity (setup, maintenance)
+- Risk (technical, business)
+- Timeline (implementation time)
+</comparison_dimensions>
+
+<output_format>
+## Comparison Matrix
+| Dimension | Option A | Option B | Option C |
+|-----------|----------|----------|----------|
+
+## Analysis
+For each dimension, explain the differences
+
+## Recommendation
+Ranked recommendation with reasoning
+</output_format>

+# GPT-5 Specific Techniques
+
+## Overview
+
+GPT-5 represents a significant advancement in LLM capabilities, requiring updated prompting strategies that differ from GPT-4 and earlier models. This guide covers GPT-5-specific techniques based on official OpenAI guidelines.
+
+## Key Architectural Changes
+
+### What's Different in GPT-5
+
+1. **Agentic behavior** - GPT-5 is proactive and thorough by default
+2. **Better reasoning** - Native step-by-step thinking without explicit prompting
+3. **Instruction adherence** - Superior at following complex constraints
+4. **Reduced hallucination** - More factually accurate
+5. **Context handling** - Better at long-context tasks
+
+### What No Longer Works
+
+**Old GPT-4 techniques that fail with GPT-5:**
+
+❌ **Excessive repetition** - Don't repeat instructions multiple times
+```
+BAD (GPT-4 style):
+"Write code. Remember to write code. Make sure you write code.
+The task is to write code."
+
+GOOD (GPT-5):
+"Write a TypeScript authentication service with JWT support."
+```
+
+❌ **Over-prompting for reasoning** - GPT-5 reasons well by default
+```
+BAD:
+"Think carefully. Take your time. Reason step-by-step. Don't rush.
+Make sure to think deeply..."
+
+GOOD:
+"Analyze this architecture decision:"
+[GPT-5 will reason appropriately without excessive prompting]
+```
+
+❌ **Contradictory instructions** - GPT-5 will call these out
+```
+BAD:
+"Be concise but provide extensive detail with comprehensive examples..."
+[GPT-5 may refuse or ask for clarification]
+
+GOOD:
+"Provide a detailed explanation (3-4 paragraphs) with 2 code examples"
+```
+
+## Structured Prompting Format
+
+### The Triple-S Pattern: System, Specification, Structure
+
+**Optimal GPT-5 prompt structure:**
+
+```
+SYSTEM (Role + Context):
+You are [specific role with relevant expertise]
+[Brief context about the situation]
+
+SPECIFICATION (Task + Constraints):
+Task: [Clear, specific task]
+Requirements:
+- [Requirement 1]
+- [Requirement 2]
+Constraints:
+- [Limitation 1]
+- [Limitation 2]
+
+STRUCTURE (Output Format):
+Provide output as:
+[Exact format specification]
+```
+
+**Example:**
+```
+SYSTEM:
+You are a senior security engineer reviewing authentication systems.
+This is a production system handling 1M+ daily active users.
+
+SPECIFICATION:
+Task: Review this authentication implementation for security vulnerabilities
+Requirements:
+- Focus on OWASP Top 10 vulnerabilities
+- Consider token-based auth best practices
+- Evaluate session management approach
+Constraints:
+- Only flag issues with security implications
+- Must provide specific line numbers
+- Include severity ratings (Critical/High/Medium/Low)
+
+STRUCTURE:
+For each vulnerability found:
+1. Title: [Brief description]
+2. Severity: [Rating]
+3. Location: [File:Line]
+4. Explanation: [Why this is a problem]
+5. Fix: [Specific code recommendation]
+6. References: [Relevant security standards]
+```
+
+## Reasoning Effort Control
+
+### Understanding Reasoning Effort
+
+GPT-5 includes a `reasoning_effort` parameter that controls computational intensity:
+
+- **Low** - Quick responses, simple tasks
+- **Medium** (default) - Balanced approach
+- **High** - Deep reasoning, complex problems
+
+### When to Adjust Reasoning Effort
+
+**Use Low reasoning_effort:**
+- Simple transformations
+- Formatting tasks
+- Quick classifications
+- Template filling
+- Fast iterations needed
+
+**Use Medium reasoning_effort:**
+- Standard coding tasks
+- Content generation
+- Analysis tasks
+- Most general work
+
+**Use High reasoning_effort:**
+- Complex algorithms
+- Architecture decisions
+- Security analysis
+- Mathematical proofs
+- Multi-step reasoning
+- Critical decisions
+
+### Prompting for Higher Reasoning
+
+If you can't control the API parameter, trigger higher reasoning in prompts:
+
+```
+"This is a high-stakes decision requiring careful analysis.
+Consider all edge cases and potential failure modes before responding.
+
+[Your task]"
+```
+
+**Magic phrases that trigger deeper reasoning:**
+- "This is a high-stakes/critical task"
+- "Analyze thoroughly before responding"
+- "Consider all edge cases"
+- "Think through potential failure modes"
+
+## Agentic Behavior Calibration
+
+### Understanding GPT-5's Agentic Nature
+
+GPT-5 is proactive by default - it will:
+- Ask clarifying questions
+- Suggest improvements
+- Point out potential issues
+- Offer alternatives
+- Request more context
+
+### Controlling Agentic Behavior
+
+**For maximum autonomy (task completion mode):**
+```
+"Complete this task end-to-end without asking for guidance.
+Make reasonable assumptions where needed and persist until
+the task is fully handled.
+
+[Task description]"
+```
+
+**For collaborative mode (step-by-step):**
+```
+"Work on this task incrementally, asking for my confirmation
+before making significant decisions or assumptions.
+
+[Task description]"
+```
+
+**For minimal agency (just answer):**
+```
+"Answer this question directly based only on the information
+provided. Do not suggest alternatives or ask for clarification.
+
+[Question]"
+```
+
+### Examples
+
+**Task Completion Mode:**
+```
+"Implement a complete REST API for user management with
+authentication. Make standard architectural decisions and
+persist until fully implemented. Use TypeScript, Express,
+and PostgreSQL."
+
+Result: GPT-5 will complete entire implementation without
+asking intermediate questions.
+```
+
+**Collaborative Mode:**
+```
+"Let's build a REST API for user management. Start by proposing
+the overall architecture and wait for my feedback before
+implementing."
+
+Result: GPT-5 will propose, wait for approval, then implement
+each piece with check-ins.
+```
+
+## Verbosity Management
+
+### The Verbosity Challenge
+
+GPT-5 tends to be thorough (sometimes too thorough), providing:
+- Detailed explanations
+- Multiple examples
+- Edge case discussions
+- Alternative approaches
+
+### Controlling Output Length
+
+**For concise output:**
+```
+"Provide a concise implementation:
+- Core functionality only
+- Minimal comments
+- Under 50 lines of code
+- No explanatory text"
+```
+
+**For detailed output:**
+```
+"Provide a comprehensive solution:
+- Fully documented code
+- Multiple examples showing different use cases
+- Detailed explanation of design decisions
+- Error handling for edge cases"
+```
+
+**Using word/line limits:**
+```
+"Explain JWT authentication in exactly 3 paragraphs (about 150 words total)"
+
+"Write this function in under 30 lines with inline comments"
+
+"List the top 5 issues only, one sentence each"
+```
+
+### Verbosity Spectrum
+
+```
+"Minimal" → Core answer only, no elaboration
+"Concise" → Brief answer with key points
+"Standard" → Balanced explanation with examples
+"Detailed" → Thorough with multiple examples
+"Comprehensive" → Exhaustive coverage of topic
+```
+
+## Prompt Optimization Workflow
+
+### 1. Start with Clear Structure
+
+```
+ROLE: [Who the AI is]
+TASK: [What to do]
+CONSTRAINTS: [Limitations]
+FORMAT: [Output structure]
+```
+
+### 2. Add Reasoning Guidance (if complex)
+
+```
+"Approach this step-by-step:
+1. First, [step 1]
+2. Then, [step 2]
+3. Finally, [step 3]"
+```
+
+### 3. Specify Verbosity
+
+```
+"Provide a [concise/detailed/comprehensive] [output type]
+of approximately [length]"
+```
+
+### 4. Set Agentic Behavior
+
+```
+"[Complete autonomously / Ask before major decisions /
+Answer directly without suggestions]"
+```
+
+## Common GPT-5 Patterns
+
+### Pattern 1: Code Generation
+
+```
+SYSTEM:
+You are an expert [language] developer following [style guide]
+
+TASK:
+Implement [specific feature] with these requirements:
+[Requirement list]
+
+CODE STYLE:
+- [Style point 1]
+- [Style point 2]
+
+OUTPUT:
+1. Implementation code with JSDoc/docstrings
+2. Unit tests covering main scenarios
+3. Brief usage example
+
+CONSTRAINTS:
+- Under [X] lines for main implementation
+- Follow [pattern/architecture]
+- Handle [specific edge cases]
+```
+
+### Pattern 2: Analysis Tasks
+
+```
+SYSTEM:
+You are a [domain] expert analyzing [subject]
+
+DATA:
+[Data/code/content to analyze]
+
+ANALYSIS FRAMEWORK:
+1. Identify [aspect 1]
+2. Evaluate [aspect 2]
+3. Assess [aspect 3]
+4. Recommend [improvements]
+
+OUTPUT FORMAT:
+## Summary
+[2-3 sentences]
+
+## Findings
+[Structured findings]
+
+## Recommendations
+[Prioritized action items]
+```
+
+### Pattern 3: Creative Content
+
+```
+SYSTEM:
+You are a [type] writer with expertise in [domain]
+
+TASK:
+Create [content type] about [topic]
+
+REQUIREMENTS:
+- Audience: [target audience]
+- Tone: [specific tone]

+- Style: [style guidelines]
+
+INCLUDE:
+- [Element 1]
+- [Element 2]
+
+STRUCTURE:
+[Specific outline or format]
+```
+
+### Pattern 4: Decision Support
+
+```
+SYSTEM:
+You are a [role] helping with a strategic decision
+
+DECISION CONTEXT:
+[Background information]
+
+OPTIONS:
+1. [Option 1]
+2. [Option 2]
+3. [Option 3]
+
+ANALYSIS REQUIRED:
+For each option, analyze:
+- Pros and cons
+- Risks and mitigations
+- Resource requirements
+- Implementation complexity
+- Expected outcomes
+
+RECOMMENDATION:
+Provide ranked recommendation with reasoning
+
+THINK STEP-BY-STEP:
+Consider all implications before recommending
+```
+
+## Using the GPT-5 Prompt Optimizer
+
+### What the Optimizer Does
+
+OpenAI provides a prompt optimizer that:
+- Identifies contradictions
+- Removes redundancy
+- Adds missing specifications
+- Improves structure
+- Suggests format improvements
+- Fixes common anti-patterns
+
+### When to Use It
+
+**Good candidates for optimization:**
+- Complex prompts with multiple requirements
+- Prompts getting inconsistent results
+- Long prompts with possible contradictions
+- Migrating GPT-4 prompts to GPT-5
+
+**Don't optimize:**
+- Simple, working prompts
+- Prompts that are already well-structured
+- When you need full control over exact wording
+
+### Optimization Process
+
+1. Submit prompt to optimizer
+2. Review suggested changes
+3. Understand the reasoning
+4. Test optimized version
+5. Iterate if needed
+
+**Example transformation:**
+
+**Before (GPT-4 style):**
+```
+You are a developer. Write code. Make sure to write good code.
+The code should be in Python. Don't forget to add comments.
+Remember to handle errors. The code should be clean. Make it
+maintainable. Think about edge cases. Write tests too.
+```
+
+**After (GPT-5 optimized):**
+```
+ROLE: Senior Python developer
+
+TASK: Implement [feature]
+
+REQUIREMENTS:
+- Clean, maintainable code
+- Comprehensive error handling
+- Inline comments for complex logic
+- Unit tests for main scenarios
+
+OUTPUT:
+1. Implementation
+2. Tests
+3. Usage example
+```
+
+## Advanced GPT-5 Techniques
+
+### Technique 1: Constraint Layering
+
+Stack constraints from general to specific:
+
+```
+GENERAL CONSTRAINTS:
+- Language: TypeScript
+- Framework: React
+- Style: Functional components
+
+SPECIFIC CONSTRAINTS:
+- Use hooks (useState, useEffect)
+- Props interface must be exported
+- Handle loading and error states
+
+EDGE CASE CONSTRAINTS:
+- Handle empty data gracefully
+- Debounce rapid state changes
+- Clean up subscriptions in useEffect
+```
+
+### Technique 2: Format Enforcement
+
+Use examples to enforce exact format:
+
+```
+OUTPUT FORMAT EXAMPLE:
+{
+  "status": "success|error",
+  "data": {
+    "field1": "value",
+    "field2": 123
+  },
+  "metadata": {
+    "timestamp": "ISO 8601",
+    "version": "1.0"
+  }
+}
+
+Now process this input and return in exactly this format:
+[Input data]
+```
+
+### Technique 3: Multi-Stage Reasoning
+
+Break complex tasks into explicit stages:
+
+```
+STAGE 1 - ANALYSIS:
+First, analyze the requirements and identify:
+- Core functionality needed
+- Technical constraints
+- Potential challenges
+
+STAGE 2 - DESIGN:
+Then, design the solution:
+- Propose architecture
+- Choose patterns
+- Plan data flow
+
+STAGE 3 - IMPLEMENTATION:
+Finally, implement with:
+- Clean code
+- Error handling
+- Tests
+
+Complete each stage fully before moving to the next.
+```
+
+### Technique 4: Self-Validation
+
+Ask GPT-5 to validate its own output:
+
+```
+[Task description]
+
+After completing the task, validate your output against:
+1. All requirements met
+2. No contradictions
+3. Edge cases handled
+4. Code compiles/runs
+5. Tests pass
+
+If validation fails, fix issues and re-validate.
+```
+
+## Common Mistakes with GPT-5
+
+### Mistake 1: Over-Prompting
+
+❌ **Don't:**
+```
+"Please carefully think about this step-by-step and make sure
+you reason through it thoroughly and don't rush and take your
+time to analyze..."
+```
+
+✅ **Do:**
+```
+"Analyze this step-by-step:"
+```
+
+### Mistake 2: Contradictory Requirements
+
+❌ **Don't:**
+```
+"Be very concise but include extensive detail and comprehensive
+examples covering all edge cases"
+```
+
+✅ **Do:**
+```
+"Provide a focused explanation (2-3 paragraphs) with one
+representative example"
+```
+
+### Mistake 3: Unclear Success Criteria
+
+❌ **Don't:**
+```
+"Write good, clean code that follows best practices"
+```
+
+✅ **Do:**
+```
+"Write code that:
+- Passes TypeScript strict mode
+- Has < 10 cyclomatic complexity per function
+- Includes JSDoc for public methods
+- Handles null/undefined explicitly"
+```
+
+### Mistake 4: Ignoring Agentic Behavior
+
+❌ **Don't:**
+```
+[Give vague task and get frustrated when GPT-5 asks questions]
+```
+
+✅ **Do:**
+```
+"Complete this autonomously, making standard decisions..."
+OR
+"Let's work on this step-by-step with check-ins..."
+```
+
+## Best Practices Summary
+
+### Structure
+- Use SYSTEM/SPECIFICATION/STRUCTURE format
+- Layer constraints from general to specific
+- Provide explicit examples for format
+
+### Reasoning
+- Let GPT-5 reason naturally for most tasks
+- Use "high-stakes" language for deeper analysis
+- Break complex tasks into explicit stages
+
+### Behavior
+- Set clear agentic behavior expectations
+- Use "persist until complete" for autonomy
+- Use "ask before major decisions" for collaboration
+
+### Verbosity

+# Prompt Optimization Strategies
+
+## Overview
+
+This guide covers systematic approaches to analyzing and improving prompts that aren't giving you the results you need. Learn how to diagnose problems, apply fixes, and measure improvements.
+
+## The Optimization Process
+
+```
+1. IDENTIFY → What's wrong with current results?
+2. DIAGNOSE → Why is the prompt failing?
+3. FIX → Apply appropriate optimization
+4. TEST → Verify improvement
+5. ITERATE → Refine further if needed
+```
+
+---
+
+## Step 1: Identify the Problem
+
+### Common Prompt Problems
+
+| Problem | Symptoms | Quick Test |
+|---------|----------|------------|
+| **Vague instructions** | Inconsistent outputs, missing requirements | Run prompt 3 times - do you get similar results? |
+| **Missing context** | Wrong assumptions, irrelevant responses | Does the prompt include all necessary background? |
+| **Unclear format** | Output structure varies | Does prompt specify exact format? |
+| **Too complex** | Partial completion, confusion | Does prompt try to do too much at once? |
+| **Wrong technique** | Poor accuracy, missed patterns | Does task match technique used? |
+| **Model mismatch** | Suboptimal results | Are you using model-specific features? |
+| **No examples** | Pattern not learned | Would examples help? |
+| **Ambiguous terms** | Misinterpreted requirements | Are terms like "professional" defined? |
+
+### Diagnostic Questions
+
+Ask yourself:
+
+**Clarity:**
+- [ ] Is the task stated explicitly?
+- [ ] Are all requirements spelled out?
+- [ ] Would a junior developer understand this?
+
+**Completeness:**
+- [ ] Is all necessary context included?
+- [ ] Are constraints specified?
+- [ ] Is output format defined?
+
+**Consistency:**
+- [ ] Does running it 3x give similar results?
+- [ ] Are there contradictory instructions?
+- [ ] Is terminology used consistently?
+
+**Appropriateness:**
+- [ ] Is the right technique being used?
+- [ ] Is this the right model for the task?
+- [ ] Is complexity level appropriate?
+
+---
+
+## Step 2: Diagnose Root Cause
+
+### Problem: Inconsistent Results
+
+**Diagnosis:**
+- Instructions too vague
+- Missing constraints
+- Ambiguous terminology
+- No output format specified
+
+**How to confirm:**
+Run the same prompt 3-5 times and compare outputs.
+
+**Evidence:**
+```
+Run 1: Returns JSON
+Run 2: Returns markdown table
+Run 3: Returns plain text
+
+Diagnosis: No format specification
+```
+
+### Problem: Wrong or Irrelevant Answers
+
+**Diagnosis:**
+- Missing context
+- Unclear task definition
+- Wrong assumptions by model
+- No examples provided
+
+**How to confirm:**
+Does the prompt include all information needed to complete the task correctly?
+
+**Evidence:**
+```
+Prompt: "Optimize this code"
+Response: "What language is this? What should I optimize for?"
+
+Diagnosis: Missing context (language, optimization goals)
+```
+
+### Problem: Partial Completion
+
+**Diagnosis:**
+- Task too complex for single shot
+- Prompt too long/confusing
+- Multiple competing requirements
+- Agentic behavior not calibrated
+
+**How to confirm:**
+Break task into smaller parts - does each part work individually?
+
+**Evidence:**
+```
+Prompt: "Build complete e-commerce backend with auth, payments, inventory"
+Response: Only implements auth, ignores rest
+
+Diagnosis: Too complex, needs progressive disclosure
+```
+
+### Problem: Incorrect Pattern Application
+
+**Diagnosis:**
+- Using few-shot when zero-shot would work
+- Missing chain-of-thought for complex reasoning
+- No examples when pattern matching needed
+- Wrong model for the task
+
+**How to confirm:**
+Compare results with different techniques.
+
+**Evidence:**
+```
+Complex math problem solved directly: Wrong answer
+Same problem with "think step-by-step": Correct answer
+
+Diagnosis: Needs chain-of-thought prompting
+```
+
+---
+
+## Step 3: Apply Fixes
+
+### Fix: Add Specificity
+
+**Before:**
+```
+"Write professional code"
+```
+
+**After:**
+```
+"Write TypeScript code following these standards:
+- Strict type checking enabled
+- JSDoc comments for all public methods
+- Error handling for all async operations
+- Maximum cyclomatic complexity of 5
+- Meaningful variable names (no abbreviations)"
+```
+
+**Why it works:** Removes ambiguity, defines "professional" explicitly.
+
+### Fix: Provide Context
+
+**Before:**
+```
+"Optimize this function:
+[code]"
+```
+
+**After:**
+```
+"Optimize this TypeScript function that processes user uploads:
+
+Context:
+- Called 1000x per minute
+- Typical input: 1-10MB files
+- Current bottleneck: O(n²) loop
+- Running in Node.js 18
+
+Optimization goals (in priority order):
+1. Reduce time complexity
+2. Lower memory usage
+3. Maintain readability
+
+[code]"
+```
+
+**Why it works:** Provides necessary context for appropriate optimization.
+
+### Fix: Specify Format
+
+**Before:**
+```
+"Analyze this code for issues"
+```
+
+**After:**
+```
+"Analyze this code for issues and respond in this exact format:
+
+## Issues Found
+
+### [Issue Title]
+- **Severity**: Critical/High/Medium/Low
+- **Category**: Security/Performance/Quality
+- **Location**: Line X
+- **Problem**: [Description]
+- **Fix**: [Specific solution]
+
+### [Next Issue]
+[Same format]
+
+## Summary
+Total issues: [count by severity]
+Recommendation: [Approve/Request Changes]"
+```
+
+**Why it works:** Guarantees consistent, parseable output.
+
+### Fix: Add Examples (Few-Shot)
+
+**Before:**
+```
+"Convert these to camelCase:
+user_name
+total_count
+is_active"
+```
+
+**After:**
+```
+"Convert these to camelCase:
+
+Examples:
+user_name → userName
+total_count → totalCount
+
+Now convert:
+is_active →
+created_at →
+max_retry_attempts →"
+```
+
+**Why it works:** Shows the pattern, improves accuracy.
+
+### Fix: Enable Reasoning (Chain-of-Thought)
+
+**Before:**
+```
+"What's the time complexity of this algorithm?"
+```
+
+**After:**
+```
+"Analyze the time complexity of this algorithm step-by-step:
+
+1. First, identify the loops and recursive calls
+2. Then, determine how many times each executes
+3. Next, calculate the overall complexity
+4. Finally, express in Big O notation
+
+Algorithm:
+[code]"
+```
+
+**Why it works:** Structured reasoning leads to correct analysis.
+
+### Fix: Break Down Complexity (Progressive Disclosure)
+
+**Before:**
+```
+"Build a complete user authentication system with OAuth,
+2FA, session management, and password reset"
+```
+
+**After:**
+```
+"Let's build a user authentication system in stages.
+
+STAGE 1: Design the overall architecture
+- Components needed
+- Data models
+- API endpoints
+
+Wait for my review before proceeding to implementation."
+```
+
+**Then after review:**
+```
+"STAGE 2: Implement the core authentication service
+- User login with email/password
+- JWT token generation
+- Session management
+
+Use the architecture we designed in Stage 1."
+```
+
+**Why it works:** Breaks overwhelming task into manageable pieces.
+
+### Fix: Add Constraints
+
+**Before:**
+```
+"Write a function to sort an array"
+```
+
+**After:**
+```
+"Write a function to sort an array with these constraints:
+
+Requirements:
+- Input: Array of numbers (may contain duplicates)
+- Output: New array, sorted ascending
+- Must be pure function (don't modify input)
+- Time complexity: O(n log n) or better
+- Language: TypeScript with strict types
+
+Edge cases to handle:
+- Empty array → return empty array
+- Single element → return copy of array
+- All same values → return copy of array
+- Negative numbers → sort correctly"
+```
+
+**Why it works:** Removes ambiguity, ensures all cases handled.
+
+### Fix: Use Model-Specific Features
+
+**For GPT-5:**
+
+**Before (generic):**
+```
+"Implement this feature"
+```
+
+**After (GPT-5 optimized):**
+```
+SYSTEM: Senior TypeScript developer
+TASK: Implement user authentication service
+CONSTRAINTS:
+- Use JWT with refresh tokens
+- TypeScript strict mode
+- Include error handling
+OUTPUT: Complete implementation with tests
+BEHAVIOR: Complete autonomously without asking questions
+VERBOSITY: Concise - core functionality only
+```
+
+**For Claude:**
+
+**Before (generic):**
+```
+"Review this code for security issues"
+```
+
+**After (Claude optimized):**
+```xml
+<instruction>
+Review this code for security vulnerabilities
+</instruction>
+
+<code>
+[Code to review]
+</code>
+
+<focus_areas>
+- SQL injection
+- XSS attacks
+- Authentication bypasses
+- Data exposure
+</focus_areas>
+
+<output_format>
+For each vulnerability:
+- Severity: [Critical/High/Medium/Low]
+- Location: [Line number]
+- Description: [What's wrong]
+- Fix: [How to remediate]
+</output_format>
+```
+
+---
+
+## Step 4: Test Improvements
+
+### A/B Testing Prompts
+
+**Method:**
+1. Keep original prompt as baseline
+2. Create improved version
+3. Run both on same inputs (5-10 test cases)
+4. Compare results objectively
+
+**Evaluation criteria:**
+- Accuracy (does it solve the problem?)
+- Consistency (similar results each time?)
+- Completeness (all requirements met?)
+- Quality (meets standards?)
+- Format compliance (matches specification?)
+
+**Example:**
+
+| Test Case | Original Prompt | Improved Prompt | Winner |
+|-----------|----------------|-----------------|--------|
+| Case 1 | 60% accurate | 95% accurate | Improved |
+| Case 2 | Wrong format | Correct format | Improved |
+| Case 3 | Incomplete | Complete | Improved |
+| Case 4 | Correct | Correct | Tie |
+| Case 5 | Partial | Complete | Improved |
+
+**Result:** Improved prompt wins 4/5 cases, use it.
+
+### Measuring Improvement
+
+**Quantitative metrics:**
+- Success rate: X% of runs produce correct output
+- Consistency: X% of runs produce similar output
+- Completeness: X% of requirements met on average
+- Format compliance: X% match specified format
+- Token efficiency: Avg tokens to correct result
+
+**Qualitative assessment:**
+- Does it feel easier to use?
+- Do results need less manual correction?
+- Is output more predictable?
+- Are edge cases handled better?
+
+### Iterative Testing
+
+```
+Version 1 → Test → 70% success → Identify issues
+Version 2 → Test → 85% success → Identify remaining issues
+Version 3 → Test → 95% success → Good enough for production
+```
+
+Don't expect perfection on first try. Iterate.
+
+---
+
+## Step 5: Continuous Iteration
+
+### When to Iterate Further
+
+**Keep improving if:**
+- Success rate < 90%
+- Inconsistent outputs across runs
+- Missing edge cases
+- Requires manual post-processing
+- Takes multiple attempts to get right
+
+**Stop iterating when:**
+- Success rate > 95%
+- Consistent, predictable outputs
+- Handles known edge cases
+- Minimal manual correction needed
+- One-shot success most of the time
+
+### Iteration Strategies
+
+**Strategy 1: Incremental Refinement**
+1. Start with basic working prompt
+2. Identify most common failure mode
+3. Add constraint/example to fix it
+4. Test
+5. Repeat for next most common failure
+
+**Strategy 2: Template Evolution**
+1. Create template with placeholders
+2. Test with multiple scenarios
+3. Identify missing sections
+4. Add new sections to template
+5. Retest with scenarios
+
+**Strategy 3: Technique Stacking**
+1. Start with base technique (e.g., zero-shot)
+2. If accuracy low, add chain-of-thought
+3. If still issues, add few-shot examples
+4. If format wrong, add explicit structure
+5. Layer techniques until quality sufficient
+
+### Tracking What Works
+
+**Maintain a prompt library:**
+```
+prompts/
+├── code-review.md (Success rate: 97%)
+├── data-analysis.md (Success rate: 94%)
+├── documentation.md (Success rate: 99%)
+└── bug-diagnosis.md (Success rate: 91%)
+```
+
+**Document each prompt:**
+```markdown
+# Code Review Prompt
+
+**Success Rate:** 97%
+**Last Updated:** 2025-01-15
+**Model:** GPT-5 / Claude Sonnet
+
+**Use When:** Reviewing pull requests for security, performance, quality
+
+**Template:**
+[Prompt template]
+
+**Known Limitations:**
+- May miss complex race conditions
+- Better for backend than frontend code
+
+**Changelog:**
+- v3 (2025-01-15): Added self-validation step (95% → 97%)
+- v2 (2025-01-10): Added severity ratings (90% → 95%)
+- v1 (2025-01-05): Initial version (90%)
+```
+
+---

+
+---
+
+## Advanced Optimization Techniques
+
+### Technique 1: Constraint Tuning
+
+**Concept:** Find the right level of constraint specificity.
+
+**Too loose:**
+```
+"Write good code"
+```
+
+**Too tight:**
+```
+"Write code with exactly 47 lines, 3 functions named specifically
+foo, bar, baz, using only these 12 allowed keywords..."
+```
+
+**Just right:**
+```
+"Write TypeScript code:
+- 3-5 small functions (<20 lines each)
+- Descriptive names
+- One responsibility per function
+- Type-safe"
+```
+
+**Process:**
+1. Start loose
+2. Add constraints where outputs vary
+3. Stop when consistency achieved
+4. Don't over-constrain
+
+### Technique 2: Example Engineering
+
+**Concept:** Carefully craft few-shot examples for maximum learning.
+
+**Principles:**
+- **Diversity**: Cover different scenarios
+- **Edge cases**: Include tricky examples
+- **Consistency**: Same format for all
+- **Clarity**: Obvious pattern to learn
+
+**Bad examples:**
+```
+Input: "Hello"
+Output: "HELLO"
+
+Input: "Hi"
+Output: "HI"
+
+Input: "Hey"
+Output: "HEY"
+```
+(Too similar, no edge cases)
+
+**Good examples:**
+```
+Input: "Hello World"
+Output: "HELLO WORLD"
+
+Input: "it's-a test_case"
+Output: "IT'S-A TEST_CASE"
+
+Input: "123abc"
+Output: "123ABC"
+
+Input: ""
+Output: ""
+```
+(Diverse, includes spaces, punctuation, numbers, empty)
+
+### Technique 3: Format Scaffolding
+
+**Concept:** Provide the exact structure you want filled in.
+
+**Basic request:**
+```
+"Analyze this code"
+```
+
+**With scaffolding:**
+```
+"Analyze this code and fill in this template:
+
+## Code Quality: [Good/Fair/Poor]
+
+## Issues Found:
+1. [Issue]: [Description]
+   - Location: [Line X]
+   - Fix: [Solution]
+
+2. [Issue]: [Description]
+   - Location: [Line Y]
+   - Fix: [Solution]
+
+## Strengths:
+- [Strength 1]
+- [Strength 2]
+
+## Recommendation: [Approve/Request Changes]"
+```
+
+**Result:** Guaranteed format match.
+
+### Technique 4: Self-Correction Loop
+
+**Concept:** Ask the model to validate and fix its own output.
+
+**Single-pass:**
+```
+"Generate a JSON API response for user data"
+```
+
+**With self-correction:**
+```
+"Generate a JSON API response for user data.
+
+After generating:
+1. Validate JSON syntax
+2. Check all required fields present
+3. Verify data types correct
+4. Ensure no sensitive data exposed
+
+If validation fails, fix issues and regenerate."
+```
+
+**Result:** Higher quality, fewer errors.
+
+### Technique 5: Precision Through Negation
+
+**Concept:** Specify what NOT to do as well as what to do.
+
+**Positive only:**
+```
+"Write a professional email"
+```
+
+**Positive + Negative:**
+```
+"Write a professional email:
+
+DO:
+- Use formal salutation (Dear [Name])
+- State purpose in first sentence
+- Use clear, concise language
+- Include specific next steps
+
+DON'T:
+- Use contractions (don't, won't, etc.)
+- Include emojis or informal language
+- Exceed 3 paragraphs
+- End without clear call-to-action"
+```
+
+**Result:** Avoids common mistakes.
+
+---
+
+## Common Optimization Patterns
+
+### Pattern: Vague → Specific
+
+**Before:** "Make this better"
+**After:** "Refactor to reduce complexity from 15 to <5, extract helper functions, add type safety"
+
+### Pattern: No Examples → Few-Shot
+
+**Before:** "Format these dates"
+**After:** "2025-01-15 → January 15, 2025\n2024-12-01 → December 1, 2024\nNow format: 2025-03-22"
+
+### Pattern: Single-Shot → Progressive
+
+**Before:** "Build entire app"
+**After:** "Stage 1: Design architecture [wait for approval] Stage 2: Implement core [wait for approval]..."
+
+### Pattern: Generic → Model-Specific
+
+**Before:** "Review this code"
+**After (GPT-5):** "SYSTEM: Senior dev\nTASK: Code review\nCONSTRAINTS:..."
+**After (Claude):** `<instruction>Review code</instruction><code>...</code>`
+
+### Pattern: Implicit → Explicit Format
+
+**Before:** "List the issues"
+**After:** "List issues as:\n1. [Issue] - Line X - [Fix]\n2. [Issue] - Line Y - [Fix]"
+
+---
+
+## Quick Reference
+
+### Optimization Decision Tree
+
+```
+Is output inconsistent?
+├─ Yes → Add format specification + constraints
+└─ No → Continue
+
+Is output incomplete?
+├─ Yes → Check if task too complex → Use progressive disclosure
+└─ No → Continue
+
+Is output inaccurate?
+├─ Yes → Add examples (few-shot) or reasoning (CoT)
+└─ No → Continue
+
+Is output low quality?
+├─ Yes → Add quality criteria + validation step
+└─ No → Prompt is good!
+```
+
+### Quick Fixes
+
+| Symptom | Quick Fix |
+|---------|-----------|
+| Varying formats | Add exact format template |
+| Wrong answers | Add "think step-by-step" |
+| Inconsistent results | Add specific constraints |
+| Missing edge cases | Add explicit edge case handling |
+| Too verbose | Specify length limit |
+| Too brief | Request "detailed" or "comprehensive" |
+| Wrong assumptions | Provide complete context |
+| Partial completion | Break into stages |
+
+---
+
+**Remember:** Optimization is iterative. Start simple, measure results, identify failures, apply targeted fixes, and repeat until quality is sufficient. Don't over-engineer prompts that already work well enough.

+
+# PRD Generator
+
+## Overview
+
+Generate comprehensive, well-structured Product Requirements Documents (PRDs) that follow industry best practices. This skill helps product managers create clear, actionable requirements documents that align stakeholders and guide development teams.
+
+## Core Workflow
+
+When a user requests to create a PRD (e.g., "create a PRD for a user authentication feature"), follow this workflow:
+
+### Step 1: Gather Context
+
+Before generating the PRD, collect essential information through a discovery conversation:
+
+**Required Information:**
+- **Feature/Product Name**: What are we building?
+- **Problem Statement**: What problem does this solve?
+- **Target Users**: Who is this for?
+- **Business Goals**: What are we trying to achieve?
+- **Success Metrics**: How will we measure success?
+- **Timeline/Constraints**: Any deadlines or limitations?
+
+**Discovery Questions to Ask:**
+
+```
+1. What problem are you trying to solve?
+2. Who is the primary user/audience for this feature?
+3. What are the key business objectives?
+4. Are there any technical constraints we should be aware of?
+5. What does success look like? How will you measure it?
+6. What's the timeline for this feature?
+7. What's explicitly out of scope?
+```
+
+**Note:** If the user provides a detailed brief or requirements upfront, you can skip some questions. Always ask for clarification on missing critical information.
+
+### Step 2: Generate PRD Structure
+
+Use the standard PRD template from `references/prd_template.md` to create a well-structured document. The PRD should include:
+
+1. **Executive Summary** - High-level overview (2-3 paragraphs)
+2. **Problem Statement** - Clear articulation of the problem
+3. **Goals & Objectives** - What we're trying to achieve
+4. **User Personas** - Who we're building for
+5. **User Stories & Requirements** - Detailed functional requirements
+6. **Success Metrics** - KPIs and measurement criteria
+7. **Scope** - What's in and out of scope
+8. **Technical Considerations** - Architecture, dependencies, constraints
+9. **Design & UX Requirements** - UI/UX considerations
+10. **Timeline & Milestones** - Key dates and phases
+11. **Risks & Mitigation** - Potential issues and solutions
+12. **Dependencies & Assumptions** - What we're relying on
+13. **Open Questions** - Unresolved items
+
+### Step 3: Create User Stories
+
+For each major requirement, generate user stories using the standard format:
+
+```
+As a [user type],
+I want to [action],
+So that [benefit/value].
+
+Acceptance Criteria:
+- [Specific, testable criterion 1]
+- [Specific, testable criterion 2]
+- [Specific, testable criterion 3]
+```
+
+Reference `references/user_story_examples.md` for common patterns and best practices.
+
+### Step 4: Define Success Metrics
+
+Use appropriate metrics frameworks based on the product type:
+
+- **AARRR (Pirate Metrics)**: Acquisition, Activation, Retention, Revenue, Referral
+- **HEART Framework**: Happiness, Engagement, Adoption, Retention, Task Success
+- **North Star Metric**: Single key metric that represents core value
+- **OKRs**: Objectives and Key Results
+
+Consult `references/metrics_frameworks.md` for detailed guidance on each framework.
+
+### Step 5: Validate & Review
+
+Optionally run the validation script to ensure PRD completeness:
+
+```bash
+scripts/validate_prd.sh <prd_file.md>
+```
+
+This checks for:
+- All required sections present
+- User stories follow proper format
+- Success metrics are defined
+- Scope is clearly articulated
+- No placeholder text remains
+
+## Usage Patterns
+
+### Pattern 1: New Feature PRD
+
+**User Request:** "Create a PRD for adding dark mode to our mobile app"
+
+**Execution:**
+
+1. Ask discovery questions about dark mode requirements
+2. Generate PRD using template
+3. Create user stories for:
+   - Theme switching
+   - Preference persistence
+   - System-level sync
+   - Design token updates
+4. Define success metrics (adoption rate, user satisfaction)
+5. Identify technical dependencies (design system, platform APIs)
+
+### Pattern 2: Product Enhancement PRD
+
+**User Request:** "Write requirements for improving our search functionality"
+
+**Execution:**
+
+1. Gather context on current search limitations
+2. Identify user pain points and desired improvements
+3. Generate PRD with focus on:
+   - Current state analysis
+   - Proposed enhancements
+   - Impact assessment
+4. Create prioritized user stories
+5. Define before/after metrics
+
+### Pattern 3: New Product PRD
+
+**User Request:** "I need a PRD for a new analytics dashboard product"
+
+**Execution:**
+
+1. Comprehensive discovery (market analysis, user research)
+2. Generate full PRD with:
+   - Market opportunity
+   - Competitive analysis
+   - Product vision
+   - MVP scope
+   - Go-to-market considerations
+3. Detailed user stories for core features
+4. Phased rollout plan
+5. Success metrics aligned with business goals
+
+### Pattern 4: Quick PRD / One-Pager
+
+**User Request:** "Create a lightweight PRD for a small bug fix feature"
+
+**Execution:**
+
+1. Generate simplified PRD focusing on:
+   - Problem statement
+   - Solution approach
+   - Acceptance criteria
+   - Success metrics
+2. Skip sections not relevant for small scope
+3. Keep document concise (1-2 pages)
+
+## PRD Best Practices
+
+### Writing Quality Requirements
+
+**Good Requirements Are:**
+- **Specific**: Clear and unambiguous
+- **Measurable**: Can be verified/tested
+- **Achievable**: Technically feasible
+- **Relevant**: Tied to user/business value
+- **Time-bound**: Has clear timeline
+
+**Avoid:**
+- Vague language ("fast", "easy", "intuitive")
+- Implementation details (let engineers decide how)
+- Feature creep (stick to core requirements)
+- Assumptions without validation
+
+### User Story Best Practices
+
+**DO:**
+- Focus on user value, not features
+- Write from user perspective
+- Include clear acceptance criteria
+- Keep stories independent and small
+- Use consistent format
+
+**DON'T:**
+- Write technical implementation details
+- Create dependencies between stories
+- Make stories too large (epics)
+- Use internal jargon
+- Skip acceptance criteria
+
+### Scope Management
+
+**In-Scope Section:**
+- List specific features/capabilities included
+- Be explicit and detailed
+- Link to user stories
+
+**Out-of-Scope Section:**
+- Explicitly state what's NOT included
+- Prevents scope creep
+- Manages stakeholder expectations
+- Can include "future considerations"
+
+### Success Metrics Guidelines
+
+**Choose Metrics That:**
+- Align with business objectives
+- Are measurable and trackable
+- Have clear targets/thresholds
+- Include both leading and lagging indicators
+- Consider user and business value
+
+**Typical Metric Categories:**
+- **Adoption**: How many users use the feature?
+- **Engagement**: How often do they use it?
+- **Satisfaction**: Do users like it?
+- **Performance**: Does it work well?
+- **Business Impact**: Does it drive business goals?

+- [ ] **Problem is clear**: Anyone can understand what we're solving
+- [ ] **Users are identified**: We know who this is for
+- [ ] **Success is measurable**: We can determine if it worked
+- [ ] **Scope is bounded**: Clear what's in and out
+- [ ] **Requirements are testable**: QA can verify completion
+- [ ] **Timeline is realistic**: Estimates validated with engineering
+- [ ] **Risks are identified**: We've thought through what could go wrong
+- [ ] **Stakeholders aligned**: Key people have reviewed and approved
+

+
+## Tips for Product Managers
+
+### Before Writing the PRD
+
+1. **Do your research**: User interviews, data analysis, competitive analysis
+2. **Validate the problem**: Ensure it's worth solving
+3. **Check strategic alignment**: Does this fit our roadmap?
+4. **Estimate effort**: Rough t-shirt size with engineering
+5. **Consider alternatives**: Is this the best solution?
+
+### During PRD Creation
+
+1. **Be clear, not clever**: Simple language wins
+2. **Show, don't tell**: Use examples, mockups, diagrams
+3. **Think edge cases**: What could go wrong?
+4. **Prioritize ruthlessly**: What's MVP vs. nice-to-have?
+5. **Collaborate early**: Don't work in isolation
+
+### After PRD Completion
+
+1. **Review with stakeholders**: Get feedback early
+2. **Iterate based on input**: PRDs are living documents
+3. **Present, don't just share**: Walk through the PRD
+4. **Get formal sign-off**: Ensure commitment
+5. **Keep it updated**: Adjust as understanding evolves
+
+## Examples
+
+### Example 1: Mobile Feature PRD
+
+```bash
+# User: "Create a PRD for adding biometric authentication to our iOS app"
+
+# Assistant will:
+# 1. Ask discovery questions about security requirements, user personas, existing auth
+# 2. Generate PRD covering:
+#    - Problem: Password friction, security concerns
+#    - Solution: Face ID / Touch ID integration
+#    - User stories: Enable biometric, fallback to password, settings management
+#    - Metrics: Adoption rate, login success rate, support tickets
+#    - Technical: iOS Keychain, LocalAuthentication framework
+#    - Risks: Device compatibility, user privacy concerns
+# 3. Output formatted markdown PRD
+```
+
+### Example 2: Web Platform Enhancement
+
+```bash
+# User: "Write requirements for improving our checkout flow conversion"
+
+# Assistant will:
+# 1. Gather data on current conversion rates and drop-off points
+# 2. Generate PRD including:
+#    - Current state analysis with metrics
+#    - Proposed improvements (guest checkout, saved payment, progress indicator)
+#    - A/B test plan
+#    - Success metrics: Conversion rate increase, time to checkout
+#    - User stories for each improvement
+# 3. Include phased rollout approach
+```
+
+### Example 3: B2B Product PRD
+
+```bash
+# User: "I need a PRD for an admin dashboard for enterprise customers"
+
+# Assistant will:
+# 1. Identify B2B-specific requirements (multi-tenancy, permissions, reporting)
+# 2. Generate comprehensive PRD with:
+#    - Enterprise user personas (admin, manager, analyst)
+#    - Role-based access control requirements
+#    - Reporting and analytics needs
+#    - Integration requirements (SSO, SCIM)
+#    - Success metrics: Customer adoption, admin efficiency
+# 3. Include enterprise-specific considerations (compliance, SLAs)
+```
+
+## Troubleshooting
+
+**Issue: PRD is too long/detailed**
+
+Solution: Create a "Lean PRD" focusing on problem, solution, acceptance criteria, and metrics. Reserve full PRD for major initiatives.
+
+**Issue: Requirements are too vague**
+
+Solution: Add specific examples, use concrete numbers, include visual references. Replace "fast" with "loads in under 2 seconds."
+
+**Issue: Stakeholders not aligned**
+
+Solution: Share PRD early as draft, incorporate feedback, present in person, get explicit sign-off before development starts.
+
+**Issue: Scope keeps expanding**
+
+Solution: Use "Out of Scope" section aggressively, create separate PRDs for future phases, tie scope to timeline constraints.
+
+**Issue: Engineers say it's not feasible**
+
+Solution: Involve engineering earlier in process, be flexible on solution approach, focus on problem not implementation.
+
+## Best Practices Summary
+
+1. **Start with the problem, not the solution**
+2. **Write for your audience** (execs need summary, engineers need details)
+3. **Be specific and measurable** (avoid vague language)
+4. **Include visuals** (mockups, diagrams, flows)
+5. **Define success upfront** (metrics, not features)
+6. **Scope aggressively** (MVP mentality)
+7. **Collaborate, don't dictate** (get input from all functions)
+8. **Keep it updated** (PRD is a living document)
+9. **Focus on "why" and "what", not "how"** (let engineers solve "how")
+10. **Make it skimmable** (headers, bullets, summaries)

+
+## Overview
+
+### Why Metrics Matter
+
+**Metrics help you:**
+- Measure feature success objectively
+- Make data-driven decisions
+- Align teams around shared goals
+- Identify what's working and what's not
+- Communicate impact to stakeholders
+
+### Types of Metrics
+
+**Leading Indicators:** Predict future outcomes
+- Example: Free trial sign-ups → Future revenue
+
+**Lagging Indicators:** Measure past results
+- Example: Monthly revenue, churn rate
+
+**Actionable vs. Vanity Metrics**
+- **Actionable:** Can influence through product changes (e.g., conversion rate)
+- **Vanity:** Looks good but doesn't drive decisions (e.g., total registered users)
+
+---
+
+## AARRR (Pirate Metrics)
+
+Created by Dave McClure, this framework focuses on the customer lifecycle.
+
+### The Five Stages
+
+```
+Acquisition → Activation → Retention → Revenue → Referral
+```
+
+### 1. Acquisition
+
+**What:** How do users find you?
+
+**Key Metrics:**
+- Website traffic
+- App store impressions
+- Click-through rate (CTR) from ads
+- Cost per acquisition (CPA)
+- Traffic sources (organic, paid, referral)
+
+**Example Targets:**
+- 10,000 monthly website visitors
+- CAC < $50
+- 5% CTR on paid ads
+
+**Questions to Answer:**
+- Which channels drive the most users?
+- What's our cost per channel?
+- Which campaigns convert best?
+
+---
+
+### 2. Activation
+
+**What:** Do users have a great first experience?
+
+**Key Metrics:**
+- Sign-up completion rate
+- Time to "aha moment"
+- Percentage reaching key milestone
+- Onboarding completion rate
+- Feature adoption in first session
+
+**Example Targets:**
+- 60% sign-up completion
+- 40% reach "aha moment" in first session
+- 80% complete onboarding
+
+**Questions to Answer:**
+- What does a great first experience look like?
+- Where do users drop off in onboarding?
+- How quickly do users find value?
+
+**Example "Aha Moments":**
+- **Slack:** Send your first message
+- **Dropbox:** Upload your first file
+- **Airbnb:** Complete your first booking
+
+---
+
+### 3. Retention
+
+**What:** Do users come back?
+
+**Key Metrics:**
+- Daily/Weekly/Monthly Active Users (DAU/WAU/MAU)
+- Retention curves (Day 1, Day 7, Day 30)
+- Churn rate
+- Session frequency
+- Feature usage over time
+
+**Example Targets:**
+- 40% Day 7 retention
+- 25% Day 30 retention
+- < 5% monthly churn
+
+**Cohort Analysis:**
+```
+| Cohort    | Week 1 | Week 2 | Week 3 | Week 4 |
+|-----------|--------|--------|--------|--------|
+| Jan 2024  | 100%   | 45%    | 30%    | 25%    |
+| Feb 2024  | 100%   | 50%    | 35%    | 28%    |
+```
+
+**Questions to Answer:**
+- What makes users come back?
+- When do users churn?
+- How can we re-engage inactive users?
+
+---
+
+### 4. Revenue
+
+**What:** How do you monetize?
+
+**Key Metrics:**
+- Monthly Recurring Revenue (MRR)
+- Average Revenue Per User (ARPU)
+- Customer Lifetime Value (LTV)
+- Conversion to paid rate
+- Upsell/cross-sell rate
+
+**Example Targets:**
+- 5% free-to-paid conversion
+- $50 ARPU
+- LTV:CAC ratio > 3:1
+
+**Formulas:**
+```
+LTV = ARPU × Average Customer Lifespan
+LTV:CAC = Lifetime Value ÷ Customer Acquisition Cost
+Churn Rate = Customers Lost ÷ Total Customers × 100
+```
+
+**Questions to Answer:**
+- Which features drive conversions?
+- What's our payback period?
+- How can we increase ARPU?
+
+---
+

+- NPS > 50
+- K-factor > 1 (viral growth)
+
+**Formulas:**
+```
+K-factor = (Number of Invites per User) × (Conversion Rate of Invites)
+NPS = % Promoters - % Detractors
+```
+
+**Questions to Answer:**
+- Why do users refer others?
+- How can we incentivize referrals?
+- What makes us shareable?
+
+---

+---
+
+## Metrics Anti-Patterns
+
+### Common Mistakes
+
+**1. Too Many Metrics**
+- **Problem:** Tracking everything = focusing on nothing
+- **Solution:** Choose 3-5 key metrics per initiative
+
+**2. Vanity Metrics**
+- **Problem:** Total users looks good but doesn't inform decisions
+- **Solution:** Focus on active users, engagement, retention
+
+**3. Lagging Only**
+- **Problem:** Only tracking revenue = rear-view mirror
+- **Solution:** Balance with leading indicators (activation, engagement)
+
+**4. No Targets**
+- **Problem:** Tracking without goals
+- **Solution:** Set specific, time-bound targets
+
+**5. Not Segmenting**
+- **Problem:** Average metrics hide important patterns
+- **Solution:** Segment by user type, cohort, feature usage
+
+---

+## Acceptance Criteria Patterns
+
+### Given-When-Then Format
+
+Most structured format, excellent for complex logic:
+
+```
+Given [initial context/state],
+When [action/event],
+Then [expected outcome].
+```
+
+**Example:**
+```
+Given I'm a logged-in user with items in my cart,
+When I apply a 20% discount code,
+Then the cart total is reduced by 20% and displays the discount.
+```
+
+### Checklist Format
+
+Simpler, good for straightforward requirements:
+
+```
+- [ ] Requirement 1
+- [ ] Requirement 2
+- [ ] Edge case handling
+```
+
+### Table Format
+
+Great for multiple scenarios:
+
+| Condition | Action | Expected Result |
+|-----------|--------|----------------|
+| Valid email | Click "Send" | Confirmation message |
+| Invalid email | Click "Send" | Error message |
+| Empty field | Click "Send" | "Required field" error |
+
+---
+
+## Common Mistakes to Avoid
+
+### ❌ Too Technical
+
+**Bad:**
+```
+As a user,
+I want the system to use Redis caching with 10-minute TTL,
+So that page loads are fast.
+```
+
+**Good:**
+```
+As a user,
+I want pages to load in under 2 seconds,
+So that I can browse efficiently.
+```
+
+**Why:** User stories focus on user value, not implementation. Let engineers choose the solution.
+
+---
+
+### ❌ Too Vague
+
+**Bad:**
+```
+As a user,
+I want the app to be fast,
+So that I have a good experience.
+```
+
+**Good:**
+```
+As a user,
+I want search results to appear in under 1 second,
+So that I can quickly find what I need.
+```
+
+**Why:** "Fast" is subjective. Be specific and measurable.
+
+---
+
+### ❌ Missing the "Why"
+
+**Bad:**
+```
+As a user,
+I want to upload profile pictures.
+```
+
+**Good:**
+```
+As a user,
+I want to upload a profile picture,
+So that other users can recognize me in the community.
+```
+
+**Why:** Understanding the "why" helps the team make better decisions.
+
+---
+
+### ❌ Multiple Actions in One Story
+
+**Bad:**
+```
+As a user,
+I want to create an account, set up my profile, and invite team members,
+So that I can start using the platform.
+```
+
+**Good:** Split into three stories:
+```
+Story 1: As a user, I want to create an account...
+Story 2: As a user, I want to set up my profile...
+Story 3: As an account owner, I want to invite team members...
+```
+
+**Why:** Stories should be small and focused on one capability.
+
+---
+
+### ❌ No Acceptance Criteria
+
+**Bad:**
+```
+As a user,
+I want to search for products,
+So that I can find what I need.
+```
+
+**Good:** Add specific criteria:
+```
+Acceptance Criteria:
+- [ ] Search works on product name and description
+- [ ] Results display in under 2 seconds
+- [ ] Displays "No results found" when no matches
+- [ ] Shows top 20 results with pagination
+```
+
+**Why:** Acceptance criteria define "done" and enable testing.
+
+---
+
+## Story Splitting Techniques
+
+When a story is too large, use these techniques to split it:
+
+### 1. By Workflow Steps
+
+**Large Story:**
+```
+As a user, I want to book a flight online.
+```
+
+**Split Stories:**
+- Search for flights
+- Select flight
+- Enter passenger details
+- Choose seat
+- Make payment
+- Receive confirmation
+
+---
+
+### 2. By User Persona
+
+**Large Story:**
+```
+As a user, I want to manage my subscriptions.
+```
+
+**Split Stories:**
+- As a free user, I want to view available plans
+- As a paid user, I want to upgrade my plan
+- As an admin, I want to manage team subscriptions
+
+---
+
+### 3. By Business Rules
+
+**Large Story:**
+```
+As a user, I want to apply discount codes.
+```
+
+**Split Stories:**
+- Apply percentage discount (e.g., 20% off)
+- Apply fixed amount discount (e.g., $10 off)
+- Apply free shipping discount
+- Handle expired discount codes
+- Limit one discount per order
+
+---
+
+### 4. By Data Variations
+
+**Large Story:**
+```
+As a user, I want to import contacts.
+```
+
+**Split Stories:**
+- Import from CSV file
+- Import from Google Contacts
+- Import from Microsoft Outlook
+- Import from LinkedIn
+
+---
+
+### 5. By CRUD Operations
+
+**Large Story:**
+```
+As a user, I want to manage my projects.
+```
+
+**Split Stories:**
+- Create a new project
+- View project details
+- Update project settings
+- Delete a project
+
+---
+
+### 6. By Happy Path / Edge Cases
+
+**MVP Story (Happy Path):**
+```
+As a user, I want to upload a profile photo (JPG, < 5MB).
+```
+
+**Follow-up Stories:**
+- Support additional formats (PNG, GIF)
+- Handle files larger than 5MB with error message
+- Auto-crop/resize images
+- Allow photo deletion
+
+---
+
+## Story Sizing Guidelines
+
+### Story Points Reference
+
+**1-2 Points (Few hours):**
+- Simple UI change
+- Copy update
+- Minor configuration
+
+**3-5 Points (1-2 days):**
+- New form with validation
+- Simple API endpoint
+- Basic feature toggle
+
+**8 Points (3-5 days):**
+- Complex form with business logic
+- Integration with third-party service
+- New database schema with migration
+
+**13+ Points (1+ weeks):**
+- Too large! Split the story
+- Consider as an Epic
+
+---
+
+## Templates for Common Scenarios
+
+### Registration/Sign-Up
+
+```
+As a new visitor,
+I want to create an account with my email,
+So that I can access personalized features.
+
+Acceptance Criteria:
+- [ ] Email and password required (password: min 8 chars, 1 number, 1 special char)
+- [ ] Email validation and duplicate check
+- [ ] Confirmation email sent upon registration
+- [ ] Automatically logged in after email confirmation
+- [ ] Option to sign up with Google/Apple (social auth)
+```
+
+### Data Export
+
+```
+As a user,
+I want to export my data as CSV,
+So that I can analyze it in Excel.
+
+Acceptance Criteria:
+- [ ] Export button in settings
+- [ ] Includes all user data (specify fields)
+- [ ] File downloads immediately (or email if > 10MB)
+- [ ] Filename format: "export_[username]_[date].csv"
+- [ ] Respects data privacy regulations (only user's own data)
+```
+
+### Error Handling
+
+```
+As a user,
+I want to see helpful error messages,
+So that I know how to fix issues.
+
+Acceptance Criteria:
+- [ ] Error messages are specific (not generic "Error occurred")
+- [ ] Suggest actionable next steps
+- [ ] Display in user's language
+- [ ] Don't expose technical details (stack traces)
+- [ ] Log errors for debugging (backend)
+```
+
+---
+
+## Best Practices Summary
+
+1. **Write from user perspective**, not system perspective
+2. **Focus on value/benefit**, not just functionality
+3. **Keep stories small** (completable in one sprint)
+4. **Make acceptance criteria testable**
+5. **Use consistent format** across your team
+6. **Include edge cases** in acceptance criteria
+7. **Collaborate** with engineers and designers when writing
+8. **Refine regularly** based on new learnings
+9. **Link to mockups/designs** when relevant
+10. **Prioritize ruthlessly** (must/should/nice-to-have)
+
+---
+
+## Additional Resources
+
+### User Story Template
+
+```
+Title: [Concise feature name]
+
+As a [specific user type],
+I want to [action/capability],
+So that [benefit/value].
+
+Acceptance Criteria:
+- [ ] [Testable criterion 1]
+- [ ] [Testable criterion 2]
+- [ ] [Edge case handling]
+
+Priority: [Must Have / Should Have / Nice to Have]
+Story Points: [1/2/3/5/8/13]
+Dependencies: [List if any]
+Design: [Link to mockups]
+Notes: [Additional context]
+```
+
+### Epic vs Story vs Task
+
+**Epic:** Large body of work (multiple sprints)
+- Example: "User Authentication System"
+
+**Story:** Deliverable value (one sprint)
+- Example: "As a user, I want to reset my password..."
+
+**Task:** Implementation step (hours/days)
+- Example: "Create password reset API endpoint"
+
+---
+
+## Conclusion
+
+Effective user stories:
+- Start with the user's perspective
+- Clearly articulate value
+- Include testable acceptance criteria
+- Are sized appropriately
+- Enable team collaboration
+
+Use these examples as templates, but adapt them to your product and users' specific needs!

+# Figma Design Validation with MCP
+
+Guide for validating UI implementation against Figma designs using Figma MCP.
+
+---
+
+## Prerequisites
+
+**Required:**
+- Figma MCP server configured
+- Access to Figma design files
+- Figma URLs for components/pages
+
+**Setup:**
+```bash
+# Install Figma MCP (follow official docs)
+# Configure API token
+# Verify access to design files
+```
+
+---
+
+## Validation Workflow
+
+### Step 1: Get Design Specifications
+
+**Using Figma MCP:**
+```
+"Get the specifications for the primary button from Figma file at [URL]"
+
+Response includes:
+- Dimensions (width, height)
+- Colors (background, text, border)
+- Typography (font, size, weight)
+- Spacing (padding, margin)
+- Border radius
+- States (default, hover, active, disabled)
+```
+
+### Step 2: Inspect Implementation
+
+**Browser DevTools:**
+1. Inspect element
+2. Check computed styles
+3. Verify dimensions
+4. Compare colors (use color picker)
+5. Check typography
+6. Test interactive states
+
+### Step 3: Document Discrepancies
+
+**Create test case or bug:**
+```
+TC-UI-001: Primary Button Visual Validation
+
+Design (Figma):
+- Size: 120x40px
+- Background: #0066FF
+- Border-radius: 8px
+- Font: 16px Medium #FFFFFF
+
+Implementation:
+- Size: 120x40px ✓
+- Background: #0052CC ✗ (wrong shade)
+- Border-radius: 8px ✓
+- Font: 16px Regular #FFFFFF ✗ (wrong weight)
+
+Status: FAIL
+Bugs: BUG-234, BUG-235
+```
+
+---

+
+## Bug Report for UI Discrepancies
+
+```markdown
+# BUG-XXX: [Component] doesn't match Figma design
+
+**Severity:** Medium (UI)
+**Type:** Visual
+
+## Design vs Implementation
+
+**Figma Design:** [URL]
+
+**Expected (from Figma):**
+- Button background: #0066FF
+- Font weight: 600 (Semi-bold)
+- Padding: 12px 24px
+
+**Actual (in implementation):**
+- Button background: #0052CC ❌
+- Font weight: 400 (Regular) ❌
+- Padding: 12px 24px ✓
+
+## Screenshots
+
+- Figma design: [attach]
+- Current implementation: [attach]
+- Side-by-side comparison: [attach]
+
+## Impact
+
+Users see inconsistent branding. Button appears less prominent than designed.
+```
+
+---
+
+## Automation Ideas
+
+### Visual Regression Testing
+- Capture screenshots
+- Compare against Figma exports
+- Highlight pixel differences
+- Tools: Percy, Chromatic, BackstopJS
+
+### Design Token Validation
+- Extract Figma design tokens
+- Compare with CSS variables
+- Flag mismatches
+- Automate with scripts
+
+---
+
+## Best Practices
+
+**DO:**
+- ✅ Always reference specific Figma URLs
+- ✅ Test all component states
+- ✅ Check responsive breakpoints
+- ✅ Document exact values (not "close enough")
+- ✅ Screenshot both design and implementation
+- ✅ Test in multiple browsers
+
+**DON'T:**
+- ❌ Assume "it looks right"
+- ❌ Skip hover/active states
+- ❌ Ignore small color differences
+- ❌ Test only on one screen size
+- ❌ Forget to check typography
+- ❌ Miss spacing issues
+
+---
+
+## Checklist for UI Test Cases
+
+Per component:
+- [ ] Figma URL documented
+- [ ] Desktop layout validated
+- [ ] Mobile/tablet responsive checked
+- [ ] All interactive states tested
+- [ ] Colors match exactly (use color picker)
+- [ ] Typography specifications correct
+- [ ] Spacing (padding/margins) accurate
+- [ ] Icons match design
+- [ ] Shadows/borders match
+- [ ] Animations match timing/easing
+
+---
+
+## Quick Reference
+
+| Element | What to Check | Tool |
+|---------|---------------|------|
+| Colors | Hex values exact | Browser color picker |
+| Spacing | Padding/margin px | DevTools computed styles |
+| Typography | Font, size, weight | DevTools font panel |
+| Layout | Width, height, position | DevTools box model |
+| States | Hover, active, focus | Manual interaction |
+| Responsive | Breakpoint behavior | DevTools device mode |
+
+---
+
+**Remember:** Pixel-perfect implementation builds user trust and brand consistency.

+# Regression Testing Guide
+
+Comprehensive guide to regression testing strategies and execution.
+
+---
+
+## What is Regression Testing?
+
+**Definition:** Re-testing existing functionality to ensure new changes haven't broken anything.
+
+**When to run:**
+- Before every release
+- After bug fixes
+- After new features
+- After refactoring
+- Weekly/nightly builds
+
+---
+
+## Regression Test Suite Structure
+
+### 1. Smoke Test Suite (15-30 min)
+
+**Purpose:** Quick sanity check
+
+**When:** Daily, before detailed testing
+
+**Coverage:**
+- Critical user paths
+- Core functionality
+- System health checks
+- Build stability
+
+**Example Smoke Suite:**
+```
+SMOKE-001: User can login
+SMOKE-002: User can navigate to main features
+SMOKE-003: Critical API endpoints respond
+SMOKE-004: Database connectivity works
+SMOKE-005: User can complete primary action
+SMOKE-006: User can logout
+```
+
+### 2. Full Regression Suite (2-4 hours)
+
+**Purpose:** Comprehensive validation
+
+**When:** Before releases, weekly
+
+**Coverage:**
+- All functional test cases
+- Integration scenarios
+- UI validation
+- Data integrity
+- Security checks
+
+### 3. Targeted Regression (30-60 min)
+
+**Purpose:** Test impacted areas
+
+**When:** After specific changes
+
+**Coverage:**
+- Modified feature area
+- Related components
+- Integration points
+- Dependent functionality
+
+---
+
+## Building a Regression Suite
+
+### Step 1: Identify Critical Paths
+
+**Questions:**
+- What can users absolutely NOT live without?
+- What generates revenue?
+- What handles sensitive data?
+- What's used most frequently?
+
+**Example Critical Paths:**
+- User authentication
+- Payment processing
+- Data submission
+- Report generation
+- Core business logic
+
+### Step 2: Prioritize Test Cases
+
+**P0 (Must Run):**
+- Business-critical functionality
+- Security-related tests
+- Data integrity checks
+- Revenue-impacting features
+
+**P1 (Should Run):**
+- Major features
+- Common user flows
+- Integration points
+- Performance checks
+
+**P2 (Nice to Run):**
+- Minor features
+- Edge cases
+- UI polish
+- Optional functionality
+
+### Step 3: Group by Feature Area
+
+```
+Authentication & Authorization
+├─ Login/Logout
+├─ Password reset
+├─ Session management
+└─ Permissions
+
+Payment Processing
+├─ Checkout flow
+├─ Payment methods
+├─ Refunds
+└─ Receipt generation
+
+User Management
+├─ Profile updates
+├─ Preferences
+├─ Account settings
+└─ Data export
+```
+
+---
+
+## Regression Suite Examples
+
+### E-commerce Regression Suite
+
+**Smoke Tests (20 min):**
+1. Homepage loads
+2. User can login
+3. Product search works
+4. Add to cart functions
+5. Checkout accessible
+6. Payment gateway responds
+
+**Full Regression (3 hours):**
+
+**User Account (30 min):**
+- Registration
+- Login/Logout
+- Password reset
+- Profile updates
+- Address management
+
+**Product Catalog (45 min):**
+- Browse categories
+- Search functionality
+- Filters and sorting
+- Product details
+- Image zoom
+- Reviews display
+
+**Shopping Cart (30 min):**
+- Add items
+- Update quantities
+- Remove items
+- Apply discounts
+- Save for later
+- Cart persistence
+
+**Checkout & Payment (45 min):**
+- Guest checkout
+- Registered user checkout
+- Multiple addresses
+- Payment methods
+- Order confirmation
+- Email notifications
+
+**Order Management (30 min):**
+- Order history
+- Order tracking
+- Cancellations
+- Returns/Refunds
+- Reorders
+
+---
+
+## Execution Strategy
+
+### Test Execution Order
+
+**1. Smoke first**
+- If smoke fails → stop, fix build
+- If smoke passes → proceed to full regression
+
+**2. P0 tests next**
+- Critical functionality
+- Must pass before proceeding
+
+**3. P1 then P2**
+- Complete remaining tests
+- Track failures
+
+**4. Exploratory**
+- Unscripted testing
+- Find unexpected issues
+
+### Pass/Fail Criteria
+
+**PASS:**
+- All P0 tests pass
+- 90%+ P1 tests pass
+- No critical bugs open
+- Performance acceptable
+
+**FAIL (Block Release):**
+- Any P0 test fails
+- Critical bug discovered
+- Security vulnerability
+- Data loss scenario
+
+**CONDITIONAL PASS:**
+- P1 failures with workarounds
+- Known issues documented
+- Fix plan in place
+
+---
+
+## Regression Test Management
+
+### Test Suite Maintenance
+
+**Monthly Review:**
+- Remove obsolete tests
+- Update changed functionality
+- Add new critical paths
+- Optimize slow tests
+
+**After Each Release:**
+- Update test data
+- Fix broken tests
+- Add regression for bugs found
+- Document changes
+
+### Automation Considerations
+
+**Good Candidates for Automation:**
+- Stable, repetitive tests
+- Smoke tests
+- API tests
+- Data validation
+- Cross-browser checks
+
+**Keep Manual:**
+- Exploratory testing
+- Usability evaluation
+- Visual design validation
+- Complex user scenarios
+

+## Regression Test Execution Report
+
+```markdown
+# Regression Test Report: Release 2.5.0
+
+**Date:** 2024-01-15
+**Build:** v2.5.0-rc1
+**Tester:** QA Team
+**Environment:** Staging
+
+## Summary
+
+| Suite | Total | Pass | Fail | Blocked | Pass Rate |
+|-------|-------|------|------|---------|-----------|
+| Smoke | 10 | 10 | 0 | 0 | 100% |
+| P0 Critical | 25 | 23 | 2 | 0 | 92% |
+| P1 High | 50 | 47 | 2 | 1 | 94% |
+| P2 Medium | 40 | 38 | 1 | 1 | 95% |
+| **TOTAL** | **125** | **118** | **5** | **2** | **94%** |
+
+## Critical Failures (P0)
+
+### BUG-234: Payment processing fails for Visa
+- **Test:** TC-PAY-001
+- **Impact:** High - Blocks 40% of transactions
+- **Status:** In Progress
+- **ETA:** 2024-01-16
+
+### BUG-235: User session expires prematurely
+- **Test:** TC-AUTH-045
+- **Impact:** Medium - Users logged out unexpectedly
+- **Status:** Under investigation
+
+## Recommendation
+
+**Status:** ⚠️ CONDITIONAL GO
+- Fix BUG-234 (payment) before release
+- BUG-235 acceptable with documented workaround
+- Retest after fixes
+- Final regression run before production deployment
+
+## Risks
+
+- Payment issue could impact revenue
+- Session bug may frustrate users
+- Limited time before release deadline
+
+## Next Steps
+
+1. Fix BUG-234 by EOD
+2. Retest payment flow
+3. Document session workaround
+4. Final smoke test before release
+```
+
+---
+
+## Common Pitfalls
+
+**❌ Don't:**
+- Run same tests without updating
+- Skip regression "to save time"
+- Ignore failures in low-priority tests
+- Test only happy paths
+- Forget to update test data
+- Run regression once and forget
+
+**✅ Do:**
+- Maintain suite regularly
+- Run regression consistently
+- Investigate all failures
+- Include edge cases
+- Keep test data fresh
+- Automate repetitive tests
+
+---
+

+## SQL Query Patterns
+
+### SELECT Queries
+
+#### Basic SELECT
+
+```sql
+-- ✅ Select only needed columns
+SELECT
+    user_id,
+    email,
+    created_at
+FROM users
+WHERE status = 'active'
+    AND created_at > NOW() - INTERVAL '30 days'
+ORDER BY created_at DESC
+LIMIT 100;
+
+-- ❌ Avoid SELECT *
+SELECT * FROM users;  -- Wastes resources
+```
+
+#### JOINs
+
+```sql
+-- INNER JOIN (most common)
+SELECT
+    o.order_id,
+    o.total,
+    c.name AS customer_name,
+    c.email
+FROM orders o
+INNER JOIN customers c ON o.customer_id = c.customer_id
+WHERE o.created_at >= '2024-01-01';
+
+-- LEFT JOIN (include all left rows)
+SELECT
+    c.customer_id,
+    c.name,
+    COUNT(o.order_id) AS order_count,
+    COALESCE(SUM(o.total), 0) AS total_spent
+FROM customers c
+LEFT JOIN orders o ON c.customer_id = o.customer_id
+GROUP BY c.customer_id, c.name;
+
+-- Multiple JOINs
+SELECT
+    o.order_id,
+    c.name AS customer_name,
+    p.product_name,
+    oi.quantity,
+    oi.price
+FROM orders o
+INNER JOIN customers c ON o.customer_id = c.customer_id
+INNER JOIN order_items oi ON o.order_id = oi.order_id
+INNER JOIN products p ON oi.product_id = p.product_id
+WHERE o.status = 'completed';
+```
+
+#### Subqueries
+
+```sql
+-- Subquery in WHERE
+SELECT name, email
+FROM customers
+WHERE customer_id IN (
+    SELECT DISTINCT customer_id
+    FROM orders
+    WHERE total > 1000
+);
+
+-- Correlated subquery
+SELECT
+    c.name,
+    (SELECT COUNT(*)
+     FROM orders o
+     WHERE o.customer_id = c.customer_id) AS order_count
+FROM customers c;
+
+-- ✅ Better: Use JOIN instead
+SELECT
+    c.name,
+    COUNT(o.order_id) AS order_count
+FROM customers c
+LEFT JOIN orders o ON c.customer_id = o.customer_id
+GROUP BY c.customer_id, c.name;
+```
+
+### Aggregation
+
+```sql
+-- GROUP BY with aggregates
+SELECT
+    category,
+    COUNT(*) AS product_count,
+    AVG(price) AS avg_price,
+    MIN(price) AS min_price,
+    MAX(price) AS max_price,
+    SUM(stock_quantity) AS total_stock
+FROM products
+GROUP BY category
+HAVING COUNT(*) > 5
+ORDER BY avg_price DESC;
+
+-- Multiple GROUP BY columns
+SELECT
+    DATE_TRUNC('month', created_at) AS month,
+    category,
+    SUM(total) AS monthly_sales
+FROM orders
+GROUP BY DATE_TRUNC('month', created_at), category
+ORDER BY month DESC, monthly_sales DESC;
+
+-- ROLLUP for subtotals
+SELECT
+    COALESCE(category, 'TOTAL') AS category,
+    COALESCE(brand, 'All Brands') AS brand,
+    SUM(sales) AS total_sales
+FROM products
+GROUP BY ROLLUP(category, brand);
+```
+
+### Window Functions (PostgreSQL, SQL Server, MySQL 8+)
+
+```sql
+-- ROW_NUMBER
+SELECT
+    customer_id,
+    order_date,
+    total,
+    ROW_NUMBER() OVER (
+        PARTITION BY customer_id
+        ORDER BY order_date DESC
+    ) AS order_rank
+FROM orders;
+
+-- Running totals
+SELECT
+    order_date,
+    total,
+    SUM(total) OVER (
+        ORDER BY order_date
+        ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
+    ) AS running_total
+FROM orders;
+
+-- RANK vs DENSE_RANK
+SELECT
+    product_name,
+    sales,
+    RANK() OVER (ORDER BY sales DESC) AS rank,
+    DENSE_RANK() OVER (ORDER BY sales DESC) AS dense_rank,
+    NTILE(4) OVER (ORDER BY sales DESC) AS quartile
+FROM products;
+
+-- LAG and LEAD
+SELECT
+    order_date,
+    total,
+    LAG(total, 1) OVER (ORDER BY order_date) AS prev_total,
+    LEAD(total, 1) OVER (ORDER BY order_date) AS next_total,
+    total - LAG(total, 1) OVER (ORDER BY order_date) AS change
+FROM orders;
+```
+
+### CTEs (Common Table Expressions)
+
+```sql
+-- Simple CTE
+WITH active_customers AS (
+    SELECT customer_id, name, email
+    FROM customers
+    WHERE status = 'active'
+)
+SELECT
+    ac.name,
+    COUNT(o.order_id) AS order_count
+FROM active_customers ac
+LEFT JOIN orders o ON ac.customer_id = o.customer_id
+GROUP BY ac.customer_id, ac.name;
+
+-- Multiple CTEs
+WITH
+monthly_sales AS (
+    SELECT
+        DATE_TRUNC('month', order_date) AS month,
+        SUM(total) AS sales
+    FROM orders
+    GROUP BY DATE_TRUNC('month', order_date)
+),
+avg_monthly AS (
+    SELECT AVG(sales) AS avg_sales
+    FROM monthly_sales
+)
+SELECT
+    ms.month,
+    ms.sales,
+    am.avg_sales,
+    ms.sales - am.avg_sales AS variance
+FROM monthly_sales ms
+CROSS JOIN avg_monthly am
+ORDER BY ms.month;
+
+-- Recursive CTE (hierarchies)
+WITH RECURSIVE org_tree AS (
+    -- Base case
+    SELECT
+        employee_id,
+        name,
+        manager_id,
+        1 AS level,
+        ARRAY[employee_id] AS path
+    FROM employees
+    WHERE manager_id IS NULL
+
+    UNION ALL
+
+    -- Recursive case
+    SELECT
+        e.employee_id,
+        e.name,
+        e.manager_id,
+        ot.level + 1,
+        ot.path || e.employee_id
+    FROM employees e
+    INNER JOIN org_tree ot ON e.manager_id = ot.employee_id
+)
+SELECT * FROM org_tree ORDER BY path;
+```
+
+## Query Optimization
+
+### 1. Use Indexes Effectively
+
+```sql
+-- Create index on frequently queried columns
+CREATE INDEX idx_users_email ON users(email);
+CREATE INDEX idx_orders_customer_date ON orders(customer_id, order_date);
+
+-- Composite index (order matters!)
+CREATE INDEX idx_orders_composite
+ON orders(status, customer_id, order_date);
+
+-- ✅ This query uses the index
+SELECT * FROM orders
+WHERE status = 'pending'
+    AND customer_id = 123
+    AND order_date > '2024-01-01';
+
+-- ❌ This doesn't use the index (skips first column)
+SELECT * FROM orders
+WHERE customer_id = 123;
+
+-- Partial/Filtered index (smaller, faster)
+CREATE INDEX idx_active_users
+ON users(email)
+WHERE status = 'active';
+
+-- Covering index (includes all needed columns)
+CREATE INDEX idx_users_covering
+ON users(email)
+INCLUDE (name, created_at);
+```
+
+### 2. Avoid SELECT *
+
+```sql
+-- ❌ Bad: Retrieves all columns
+SELECT * FROM users;
+
+-- ✅ Good: Select only needed columns
+SELECT user_id, email, name FROM users;
+
+-- ✅ Good: More efficient for joins
+SELECT
+    u.user_id,
+    u.email,
+    o.order_id,
+    o.total
+FROM users u
+INNER JOIN orders o ON u.user_id = o.user_id;
+```
+
+### 3. Optimize JOINs
+
+```sql
+-- ❌ Bad: Filtering after JOIN
+SELECT u.name, o.total
+FROM users u
+LEFT JOIN orders o ON u.user_id = o.user_id
+WHERE o.status = 'completed';
+
+-- ✅ Good: Filter before JOIN
+SELECT u.name, o.total
+FROM users u
+INNER JOIN (
+    SELECT user_id, total
+    FROM orders
+    WHERE status = 'completed'
+) o ON u.user_id = o.user_id;
+
+-- ✅ Even better: Use WHERE with INNER JOIN
+SELECT u.name, o.total
+FROM users u
+INNER JOIN orders o ON u.user_id = o.user_id
+WHERE o.status = 'completed';
+```
+
+### 4. Use EXISTS Instead of IN
+
+```sql
+-- ❌ Slower: IN with subquery
+SELECT name FROM customers
+WHERE customer_id IN (
+    SELECT customer_id FROM orders WHERE total > 1000
+);
+
+-- ✅ Faster: EXISTS
+SELECT name FROM customers c
+WHERE EXISTS (
+    SELECT 1 FROM orders o
+    WHERE o.customer_id = c.customer_id
+        AND o.total > 1000
+);
+```
+
+### 5. Avoid Functions on Indexed Columns
+
+```sql
+-- ❌ Bad: Function prevents index usage
+SELECT * FROM users
+WHERE LOWER(email) = 'john@example.com';
+
+-- ✅ Good: Use functional index
+CREATE INDEX idx_users_email_lower ON users(LOWER(email));
+
+-- Or use case-insensitive collation
+SELECT * FROM users
+WHERE email = 'john@example.com' COLLATE utf8_general_ci;
+```
+
+### 6. Limit Result Sets
+
+```sql
+-- ✅ Use LIMIT/TOP for pagination
+SELECT * FROM orders
+ORDER BY created_at DESC
+LIMIT 20 OFFSET 0;
+
+-- ✅ Use WHERE to reduce rows early
+SELECT * FROM orders
+WHERE created_at > NOW() - INTERVAL '7 days'
+ORDER BY created_at DESC;
+```
+
+### 7. Batch Operations
+
+```sql
+-- ❌ Bad: Multiple single inserts
+INSERT INTO users (name, email) VALUES ('User1', 'user1@example.com');
+INSERT INTO users (name, email) VALUES ('User2', 'user2@example.com');
+
+-- ✅ Good: Batch insert
+INSERT INTO users (name, email) VALUES
+    ('User1', 'user1@example.com'),
+    ('User2', 'user2@example.com'),
+    ('User3', 'user3@example.com');
+
+-- ✅ Good: Batch update
+UPDATE products
+SET price = price * 1.1
+WHERE category IN ('Electronics', 'Computers');
+```
+
+## EXPLAIN Plans
+
+### PostgreSQL
+
+```sql
+-- Simple EXPLAIN
+EXPLAIN
+SELECT * FROM orders WHERE customer_id = 123;
+
+-- EXPLAIN ANALYZE (actually runs query)
+EXPLAIN ANALYZE
+SELECT
+    c.name,
+    COUNT(o.order_id) AS order_count
+FROM customers c
+LEFT JOIN orders o ON c.customer_id = o.customer_id
+GROUP BY c.customer_id, c.name;
+
+-- Look for:
+-- - Seq Scan (bad, needs index)
+-- - Index Scan (good)
+-- - Bitmap Heap Scan (good for multiple rows)
+-- - Hash Join vs Nested Loop
+-- - High cost numbers
+```
+
+### MySQL
+
+```sql
+-- EXPLAIN
+EXPLAIN
+SELECT * FROM orders WHERE customer_id = 123;
+
+-- EXPLAIN ANALYZE (MySQL 8.0.18+)
+EXPLAIN ANALYZE
+SELECT * FROM orders WHERE customer_id = 123;
+
+-- Look for:
+-- - type: ALL (table scan, bad)
+-- - type: index (index scan, good)
+-- - type: ref (index lookup, great)
+-- - Extra: Using filesort (may need index)
+-- - Extra: Using temporary (may need optimization)
+```
+
+## Indexing Strategies
+
+### When to Index
+
+**✅ Index these columns:**
+- Primary keys (automatic)
+- Foreign keys
+- Columns in WHERE clauses
+- Columns in JOIN conditions
+- Columns in ORDER BY
+- Columns in GROUP BY
+
+**❌ Don't index:**
+- Small tables (< 1000 rows)
+- Columns with low cardinality (few distinct values)
+- Frequently updated columns
+- Large text/blob columns
+
+### Index Types
+
+```sql
+-- B-Tree (default, most common)
+CREATE INDEX idx_users_email ON users(email);
+
+-- Hash index (equality only, PostgreSQL)
+CREATE INDEX idx_users_email_hash ON users USING HASH(email);
+
+-- GIN (full-text search, arrays, JSONB)
+CREATE INDEX idx_posts_content_gin
+ON posts USING GIN(to_tsvector('english', content));
+
+-- GiST (geometric, full-text)
+CREATE INDEX idx_locations_gist
+ON locations USING GIST(coordinates);
+
+-- Partial index (filtered)
+CREATE INDEX idx_orders_pending
+ON orders(customer_id)
+WHERE status = 'pending';
+
+-- Expression index
+CREATE INDEX idx_users_email_domain
+ON users((email ~~ '%@gmail.com%'));
+```
+
+### Composite Index Order
+
+```sql
+-- Index column order matters!
+CREATE INDEX idx_orders_search
+ON orders(status, customer_id, created_at);
+
+-- ✅ Uses index (left-most column)
+WHERE status = 'completed'
+
+-- ✅ Uses index (left-most columns)
+WHERE status = 'completed' AND customer_id = 123
+
+-- ✅ Uses full index
+WHERE status = 'completed'
+    AND customer_id = 123
+    AND created_at > '2024-01-01'
+
+-- ❌ Doesn't use index (skips first column)
+WHERE customer_id = 123
+
+-- ❌ Doesn't use index (skips first column)
+WHERE created_at > '2024-01-01'
+```
+
+## MongoDB Queries
+
+### Find Queries
+
+```javascript
+// Basic find
+db.users.find({ status: 'active' })
+
+// Find with projection
+db.users.find(
+    { status: 'active' },
+    { name: 1, email: 1, _id: 0 }
+)

+
+## GraphQL Queries
+
+```graphql
+# Basic query
+query {
+  users {
+    id
+    name
+    email
+  }
+}
+
+# Query with arguments
+query {
+  user(id: "123") {
+    name
+    email
+    orders {
+      id
+      total
+      status
+    }
+  }
+}
+
+# Query with variables
+query GetUser($userId: ID!) {
+  user(id: $userId) {
+    name
+    email
+    orders(limit: 10, status: COMPLETED) {
+      id
+      total
+      createdAt
+    }
+  }
+}
+
+# Fragments (reusable fields)
+fragment UserFields on User {
+  id
+  name
+  email
+  createdAt
+}
+
+query {
+  user(id: "123") {
+    ...UserFields
+    orders {
+      id
+      total
+    }
+  }
+}
+
+# Avoid N+1 queries with DataLoader
+query {
+  orders {
+    id
+    total
+    customer {  # Batched by DataLoader
+      name
+      email
+    }
+  }
+}
+```
+
+## Common Anti-Patterns
+
+### ❌ N+1 Query Problem
+
+```sql
+-- Bad: N+1 queries
+SELECT * FROM customers;  -- 1 query
+-- Then for each customer:
+SELECT * FROM orders WHERE customer_id = ?;  -- N queries
+
+-- Good: Single JOIN query
+SELECT
+    c.customer_id,
+    c.name,
+    o.order_id,
+    o.total
+FROM customers c
+LEFT JOIN orders o ON c.customer_id = o.customer_id;
+```
+
+### ❌ Using OR on Different Columns
+
+```sql
+-- Bad: Can't use indexes effectively
+SELECT * FROM products
+WHERE name = 'iPhone' OR category = 'Electronics';
+
+-- Good: Use UNION
+SELECT * FROM products WHERE name = 'iPhone'
+UNION
+SELECT * FROM products WHERE category = 'Electronics';
+```
+
+### ❌ Implicit Type Conversion
+
+```sql
+-- Bad: '123' is string, user_id is integer
+SELECT * FROM users WHERE user_id = '123';
+
+-- Good: Use correct type
+SELECT * FROM users WHERE user_id = 123;
+```
+

+## PostgreSQL EXPLAIN Analysis
+
+### Run EXPLAIN
+```sql
+EXPLAIN ANALYZE
+SELECT * FROM orders WHERE customer_id = 123;
+```
+
+### What to Look For:
+
+**Seq Scan (Table Scan) ❌**
+→ Reading entire table
+→ Fix: Add index on filtered column
+→ CREATE INDEX idx_orders_customer ON orders(customer_id);
+
+**Index Scan ✅**
+→ Using index efficiently
+→ Good performance for specific rows
+
+**Bitmap Heap Scan ✅**
+→ Good for returning multiple rows
+→ Efficient index usage
+
+**Nested Loop ⚠️**
+→ Can be slow with large datasets
+→ Consider: Hash Join or Merge Join
+
+**Hash Join ✅**
+→ Good for large joins
+→ Requires memory
+
+**Cost Numbers**
+→ Higher = slower
+→ Compare before/after optimization
+→ cost=0.00..35.50 rows=10
+
+**Actual Time**
+→ Real execution time
+→ actual time=0.023..0.156 rows=10 loops=1
+
+---
+
+## MySQL EXPLAIN Analysis
+
+### Run EXPLAIN
+```sql
+EXPLAIN SELECT * FROM orders WHERE customer_id = 123;
+```
+
+### Type Column:
+
+**ALL ❌**
+→ Full table scan
+→ Fix: Add index
+
+**index ⚠️**
+→ Full index scan
+→ Better than ALL, but could improve
+
+**range ✅**
+→ Index range scan
+→ Good for WHERE with >, <, BETWEEN
+
+**ref ✅✅**
+→ Index lookup
+→ Excellent performance
+
+**eq_ref ✅✅✅**
+→ Unique index lookup
+→ Best performance
+
+**const ✅✅✅**
+→ Constant lookup (primary key)
+→ Fastest possible
+
+### Extra Column:
+
+**Using filesort ⚠️**
+→ Sorting in memory/disk
+→ Fix: Add index on ORDER BY columns
+
+**Using temporary ⚠️**
+→ Creating temporary table
+→ Fix: Optimize GROUP BY or DISTINCT
+
+**Using index ✅**
+→ Covering index (index-only scan)
+→ Excellent performance
+
+**Using where ✅**
+→ Filtering after read
+→ Normal for WHERE clauses
+
+---
+
+## MongoDB Explain Analysis
+
+### Run Explain
+```javascript
+db.orders.find({ customer_id: 123 }).explain("executionStats")
+```
+
+### What to Look For:
+
+**COLLSCAN ❌**
+→ Full collection scan
+→ Fix: Create index
+→ db.orders.createIndex({ customer_id: 1 })
+
+**IXSCAN ✅**
+→ Index scan
+→ Good performance
+
+**executionTimeMillis**
+→ Total execution time
+→ < 100ms good, > 1000ms needs optimization
+
+**nReturned vs totalDocsExamined**
+→ Efficiency ratio
+→ Ideally close to 1:1
+→ If totalDocsExamined >> nReturned, add index
+
+**Index Usage**
+→ indexName: "customer_id_1" ✅
+→ indexName: null ❌ (no index used)
+
+---
+
+## Index Recommendations
+
+### When to Create Index:
+
+1. **WHERE Clause**
+   CREATE INDEX idx_table_column ON table(column);
+
+2. **JOIN Columns**
+   CREATE INDEX idx_table_join_col ON table(join_column);
+
+3. **ORDER BY**
+   CREATE INDEX idx_table_sort ON table(sort_column);
+
+4. **Composite Index (order matters!)**
+   CREATE INDEX idx_multi ON table(col1, col2, col3);
+   → Works for: col1 | col1,col2 | col1,col2,col3
+   → NOT for: col2 | col3 | col2,col3
+
+5. **Covering Index**
+   CREATE INDEX idx_covering ON table(filter_col) INCLUDE (select_cols);
+   → Index contains all needed columns
+   → Fastest possible (index-only scan)
+
+### When NOT to Index:
+
+- Small tables (< 1000 rows)
+- Columns with low cardinality (few distinct values)
+- Frequently updated columns
+- Large text/blob columns
+
+---
+
+## Query Optimization Checklist
+
+Performance Issues:
+[ ] Check EXPLAIN plan
+[ ] Look for table scans (Seq Scan, ALL, COLLSCAN)
+[ ] Identify missing indexes
+[ ] Check JOIN types (Nested Loop on large tables)
+[ ] Look for filesort or temporary tables
+[ ] Verify index usage (Using index)
+
+Optimizations:
+[ ] Create indexes on WHERE columns
+[ ] Create indexes on JOIN columns  
+[ ] Use composite indexes (correct order)
+[ ] Add covering indexes for frequent queries
+[ ] Use LIMIT to reduce result set
+[ ] Avoid SELECT * (select only needed columns)
+[ ] Avoid functions on indexed columns
+[ ] Use EXISTS instead of IN (subqueries)
+[ ] Filter early (before JOIN)
+[ ] Use appropriate JOIN type
+
+Monitoring:
+[ ] Run EXPLAIN ANALYZE before optimization
+[ ] Create indexes
+[ ] Run EXPLAIN ANALYZE after optimization
+[ ] Compare execution time and cost
+[ ] Test with production-like data volume
+[ ] Monitor slow query log
+
+---
+
+## Example Optimization
+
+### Before (Slow)
+```sql
+-- EXPLAIN shows: Seq Scan, cost=1000.00
+SELECT * FROM orders WHERE customer_id = 123;
+```
+
+### Optimization Steps
+```sql
+-- 1. Create index
+CREATE INDEX idx_orders_customer ON orders(customer_id);
+
+-- 2. Optimize query (avoid SELECT *)
+SELECT order_id, total, created_at
+FROM orders
+WHERE customer_id = 123
+ORDER BY created_at DESC
+LIMIT 100;
+
+-- 3. Check improvement
+EXPLAIN ANALYZE
+SELECT order_id, total, created_at
+FROM orders
+WHERE customer_id = 123
+ORDER BY created_at DESC
+LIMIT 100;
+```
+
+### After (Fast)
+```
+→ Index Scan using idx_orders_customer
+→ cost=0.29..15.50 (95% improvement!)
+→ actual time=0.015..0.023
+```

+function speakText(text, rate = 1.0) {
+  if ('speechSynthesis' in window) {
+    const utterance = new SpeechSynthesisUtterance(text);
+    utterance.rate = rate;
+    utterance.pitch = 1.2; // Higher pitch for kids
+    utterance.volume = 1.0;
+    speechSynthesis.speak(utterance);
+  } else {
+    // Fallback: show text with pronunciation guide
+    showPronunciation(text);
+  }
+}
+```
+
+### Interactive Word Building
+```javascript
+function createWordBuilder(targetWord) {
+  const letters = targetWord.split('');
+  const scrambled = shuffle([...letters]);
+
+  let builtWord = [];
+
+  function addLetter(letter) {
+    builtWord.push(letter);
+    updateDisplay();
+
+    if (builtWord.join('') === targetWord) {
+      celebrate('Correct!');
+      return true;
+    }
+    return false;
+  }
+
+  function removeLetter() {
+    builtWord.pop();
+    updateDisplay();
+  }
+
+  return { addLetter, removeLetter, scrambled };
+}
+```
+
+### Reading Fluency Timer
+```javascript
+class FluencyTracker {
+  constructor(text) {
+    this.text = text;
+    this.wordCount = text.split(' ').length;
+    this.startTime = null;
+    this.endTime = null;
+  }
+
+  start() {
+    this.startTime = Date.now();
+  }
+
+  stop() {
+    this.endTime = Date.now();
+    return this.calculate();
+  }
+
+  calculate() {
+    const seconds = (this.endTime - this.startTime) / 1000;
+    const minutes = seconds / 60;
+    const wpm = Math.round(this.wordCount / minutes);
+
+    return {
+      wordsPerMinute: wpm,
+      timeSeconds: seconds,
+      wordCount: this.wordCount,
+      rating: this.getRating(wpm)
+    };
+  }
+
+  getRating(wpm) {
+    // Age-appropriate WPM benchmarks
+    if (wpm >= 100) return '🏆 Excellent!';
+    if (wpm >= 70) return '⭐ Great job!';
+    if (wpm >= 50) return '👍 Good work!';
+    return '💪 Keep practicing!';
+  }
+}

+# Sight Words Reference
+
+Comprehensive sight word lists organized by level (Dolch and Fry lists).
+
+## What Are Sight Words?
+
+Sight words are high-frequency words that appear often in text. Many don't follow regular phonics patterns, so children learn to recognize them instantly "by sight."
+
+**Why They Matter:**
+- 50-75% of all text consists of these words
+- Essential for reading fluency
+- Enable focus on content, not decoding
+- Build reading confidence
+

+description: Plan and execute technical product launches for developer tools, APIs, and technical products. Use this skill when technical PMMs need to "plan a launch", "create a launch strategy", "coordinate a product release", or "prepare for GA/beta launch".
+---
+
+# Technical Launch Planner
+
+## Overview
+
+Plan and execute successful launches for technical products, developer tools, APIs, SDKs, and platforms. This skill provides frameworks, checklists, and templates specifically designed for technical audiences and developer-focused products.

+
+```bash
+scripts/assess_launch_tier.sh
+```
+
+This determines if your launch is:
+- **Tier 1** (Major/GA) - New product, major version, significant expansion
+- **Tier 2** (Standard) - New features, integrations, regional expansion
+- **Tier 3** (Minor) - Updates, improvements, small features
+
+### 2. Generate Launch Plan

+Create your comprehensive launch plan:
+
+```bash
+scripts/generate_launch_plan.sh
+```
+
+Provides structured plan with:
+- Timeline and milestones
+- Stakeholder responsibilities
+- Developer enablement checklist
+- Go-to-market activities
+- Launch day playbook
+
+### 3. Validate Readiness
+
+Before launch, check readiness:
+
+```bash
+scripts/validate_readiness.sh
+```
+
+Validates:
+- Documentation completeness
+- Technical assets ready
+- Stakeholder alignment
+- Messaging finalized
+- Metrics instrumentation
+
+---
+
+## Core Launch Framework

+
+## Developer Launch Best Practices
+
+### 1. Documentation First
+
+**Launch is NOT ready without:**
+- ✅ Getting started guide
+- ✅ API reference
+- ✅ At least 3 code samples
+- ✅ Integration guide
+
+**Developer rule:** "If it's not documented, it doesn't exist"
+
+---
+
+### 2. Show, Don't Tell
+
+**Developers want to see code:**
+
+**Good:**
+```python
+# Initialize the SDK
+import acme_sdk
+
+client = acme_sdk.Client(api_key="your_key")
+result = client.widgets.create(name="My Widget")
+print(result.id)
+```
+
+**Bad:**
+"Our SDK makes it easy to create widgets with just a few lines of code"
+
+---
+
+### 3. Interactive > Passive
+
+**Engagement hierarchy:**
+1. 🥇 Interactive tutorial/playground
+2. 🥈 Live demo
+3. 🥉 Demo video
+4. ❌ Static screenshots
+
+---
+
+### 4. Honest Technical Communication
+
+**Developers appreciate:**
+- Limitations clearly stated
+- Performance characteristics
+- Pricing transparency
+- Migration complexity
+- Breaking changes
+
+**Developers hate:**
+- Overpromising
+- Hidden limitations
+- Surprise breaking changes
+- Vendor lock-in
+
+---
+
+### 5. Community-First Approach
+
+**Engage where developers are:**
+- Answer questions on Stack Overflow
+- Be active in GitHub discussions
+- Respond on Hacker News
+- Join relevant Discord/Slack
+- Participate in Reddit AMAs
+
+**Don't:**
+- Spam communities
+- Ignore negative feedback
+- Delete critical comments
+- Only show up for launches
+
+---
+
+## Technical Metrics
+
+### Developer Adoption Metrics
+
+**Activation:**
+- Sandbox/trial sign-ups
+- First API call within 24 hours
+- SDK downloads
+- "Hello World" completions
+
+**Engagement:**
+- Daily/Weekly Active Developers
+- API calls per developer
+- Features adopted
+- Integration depth
+
+**Retention:**
+- Day 7, 30, 90 developer retention
+- Churn rate
+- NPS (Developer)
+
+See `references/metrics_frameworks.md` for complete guide.

+
+## Common Pitfalls
+
+### Pitfall 1: Launching Without Complete Docs
+
+**Problem:** "Docs will be ready soon" = Dead launch
+
+**Solution:** Docs are non-negotiable. Delay launch if needed.
+
+---
+
+### Pitfall 2: Marketing-Speak for Developers
+
+**Problem:** "Revolutionary", "Seamless", "Game-changing"
+
+**Solution:** Use concrete technical language, metrics, code.
+
+---
+
+### Pitfall 3: Ignoring Migration Complexity
+
+**Problem:** Breaking changes with no migration guide
+
+**Solution:** Clear migration guide, migration tools, version support plan.
+
+---
+
+### Pitfall 4: Over-Indexing on Launch Day
+
+**Problem:** All effort on Day 1, nothing for ongoing adoption
+
+**Solution:** Plan 4-week post-launch content calendar.
+
+---
+
+### Pitfall 5: No Developer Feedback Loop
+
+**Problem:** Launch and disappear
+
+**Solution:** Active community engagement, regular office hours.

+# Technical Launch Messaging
+
+Messaging frameworks and templates for developer-focused product launches.
+
+---
+
+## Messaging Principles for Developers
+
+### DO:
+- ✅ **Be specific** - Use concrete technical details
+- ✅ **Show code** - Developers want to see, not read
+- ✅ **State limitations** - Honest about what it can't do
+- ✅ **Provide metrics** - Performance numbers, benchmarks
+- ✅ **Explain why** - Technical reasoning matters
+- ✅ **Link to docs** - Make it easy to try
+
+### DON'T:
+- ❌ **Use marketing jargon** - "Revolutionary", "game-changing"
+- ❌ **Oversimplify** - Developers can handle complexity
+- ❌ **Hide limitations** - They'll find them anyway
+- ❌ **Make unsubstantiated claims** - Back it up with data
+- ❌ **Skip code examples** - Abstract descriptions fail
+
+---
+
+## Messaging Framework
+
+### Problem Statement
+**Format:** [Current pain point] → [Why existing solutions fail] → [Impact on developers]
+
+**Example:**
+"Debugging distributed systems is painful. Traditional logging tools weren't built for microservices, forcing developers to manually correlate logs across dozens of services. This turns a 5-minute bug into a 5-hour investigation."
+
+---
+
+### Solution Overview
+**Format:** [What it is] → [How it works (technical)] → [Key benefit]
+
+**Example:**
+"Distributed Tracer automatically instruments your services to create a unified view of requests across your entire stack. Using OpenTelemetry standards, it correlates logs, metrics, and traces in real-time, reducing MTTR by 80%."
+
+---
+
+### Key Differentiators
+**Format:** [Feature] → [Technical implementation] → [Why it matters]
+
+**Example:**
+"Zero-config auto-instrumentation. Our SDK uses bytecode injection to automatically trace all HTTP calls, database queries, and external APIs without code changes. Deploy in under 5 minutes instead of days."
+
+---
+
+## Launch Announcement Template
+
+### Blog Post Structure
+
+```markdown
+# Introducing [Product]: [One-line value prop]
+
+## TL;DR
+- [Key point 1 with metric]
+- [Key point 2 with metric]
+- [Get started link]
+
+## The Problem
+
+[Describe the developer pain in detail. Be specific.]
+
+**Example:**
+Every API call in a distributed system touches 5-10 services. When something breaks, you're left grep'ing through gigabytes of logs, trying to piece together what happened. We've all been there.
+
+## The Solution
+
+[High-level overview]
+
+**How it works:**
+
+\`\`\`python
+# Show concrete code example
+import tracer
+
+tracer.init(api_key="your_key")
+
+# That's it. All requests automatically traced.
+\`\`\`
+
+## Key Features
+
+### 1. [Feature Name]
+
+**What it does:** [Technical description]
+
+**Why it matters:** [Developer benefit]
+
+**Example:**
+\`\`\`[language]
+[Code showing the feature]
+\`\`\`
+
+[Repeat for top 3-5 features]
+
+## Performance
+
+[Include benchmarks, metrics]
+
+- Latency: < 1ms overhead (p99)
+- Throughput: 100K traces/second per instance
+- Storage: 90-day retention included
+
+## Get Started in 5 Minutes

+
+### Examples
+
+**API Tool:**
+"For backend developers who need reliable API integrations, FastAPI Connect is an API orchestration platform that auto-retries, caches, and monitors all external calls. Unlike building retry logic yourself, we provide production-grade reliability out of the box."
+
+**Developer Platform:**
+"For platform teams building internal developer platforms, DevHub is a self-service portal that gives developers one-click access to infrastructure. Unlike traditional ticketing systems, we automate provisioning in seconds instead of days."
+
+---
+
+## Value Propositions by Persona
+
+### Backend Developers
+**Focus:** Performance, reliability, ease of integration
+
+"Reduce latency by 40% with one line of code"
+
+### DevOps/SRE
+**Focus:** Reliability, observability, automation
+
+"Cut MTTR from hours to minutes with automated root cause analysis"
+
+### Engineering Leaders
+**Focus:** Productivity, costs, team velocity
+
+"Ship 2x faster by eliminating [bottleneck]"
+
+### Security Teams
+**Focus:** Compliance, security, visibility
+
+"SOC 2 Type II compliant with built-in audit logging"
+
+---
+
+## Messaging by Launch Tier
+
+### Tier 1 (Major Launch)
+- **Bold claims** backed by data
+- **Vision** for the future
+- **Ecosystem** impact
+- **Industry** transformation
+
+**Example:**
+"Redefining how developers build distributed systems"
+
+### Tier 2 (Standard)
+- **Practical benefits**
+- **Specific use cases**

+
+---
+
+## Competitive Positioning
+
+### When to Mention Competitors
+
+**DO mention when:**
+- You have clear technical superiority
+- Migration is a key use case
+- Comparison requested by prospects
+
+**DON'T mention when:**
+- You're the market leader
+- Competitor is much larger
+- Claim isn't defensible
+
+### Competitive Messaging Template
+
+"Unlike [Competitor], [Product] [specific advantage]:
+
+**[Competitor]:**
+- [Limitation 1]
+- [Limitation 2]
+
+**[Product]:**
+- [Advantage 1] - [metric]
+- [Advantage 2] - [metric]
+
+[Code comparison or performance benchmark]"
+
+---
+
+## Technical Credibility Signals
+
+Include these to build trust:
+
+- **Open source** components used
+- **Standards** supported (OpenTelemetry, OAuth, etc.)
+- **Scale** handled (requests/sec, data volume)
+- **Customers** using in production (if allowed)
+- **Team background** (ex-Google, ex-AWS, etc.)
+- **Security** certifications (SOC 2, ISO 27001)
+- **Performance** benchmarks
+- **GitHub** stars (if applicable)
+
+---
+
+## Avoiding Common Mistakes
+
+### Mistake 1: Too Abstract
+**Bad:** "Simplify your workflow"
+**Good:** "Reduce deployment time from 45 minutes to 2 minutes"
+
+### Mistake 2: Jargon Overload
+**Bad:** "Leverage synergistic paradigms"
+**Good:** "Run the same code on AWS, GCP, and Azure"
+
+### Mistake 3: No Proof
+**Bad:** "The fastest API"
+**Good:** "p99 latency < 50ms (see benchmark: [link])"
+
+### Mistake 4: Feature List
+**Bad:** "Includes caching, retries, and monitoring"
+**Good:** "Auto-retry failed requests up to 3x with exponential backoff"
+
+### Mistake 5: Ignoring Migration
+**Bad:** [No mention of existing solutions]
+**Good:** "Migrate from [Competitor] in under 1 hour: [guide]"
+
+---
+
+## Testing Your Messaging
+
+### Internal Test
+- [ ] Can a new engineer explain the value?
+- [ ] Do engineers volunteer to use it?
+- [ ] Does it pass the "so what?" test?
+
+### External Test
+- [ ] Beta feedback positive?
+- [ ] Clear from HN/Reddit comments?
+- [ ] Low support questions about "what is it?"
+
+### Metrics to Watch
+- Email open rate (> 25% good for developer emails)
+- Click-through rate to docs (> 10%)
+- Sign-up conversion (depends on product)
+- Social engagement (shares, comments)
+- Media pickup (for Tier 1)
+
+---
+
+## Summary
+
+**Technical messaging succeeds when:**
+1. Problem is relatable
+2. Solution is clear (with code)
+3. Benefits are concrete
+4. Limitations are honest
+5. Getting started is easy
+
+**Keep developer-first always.**

+## Common Scenarios
+
+### Scenario 1: API GA Launch
+**Type:** New product
+**Users:** All (new audience)
+**Revenue:** New stream
+**Competitive:** Industry first capability
+**Technical:** New platform
+**Docs:** Complete set
+**Interest:** High
+
+**Score:** 52 → **Tier 1**
+
+---
+
+### Scenario 2: New Language SDK

+**Type:** Improvement
+**Users:** All
+**Revenue:** None direct
+**Competitive:** None
+**Technical:** Simple
+**Docs:** Updates
+**Interest:** Low
+
+**Score:** 12 → **Tier 3**
+
+---
+
+## Best Practices
+
+### Right-Sizing
+
+**Over-investing (Tier 3 as Tier 1):**
+- Wastes resources
+- Confuses users ("This isn't major")
+- Diminishes future Tier 1 launches
+
+**Under-investing (Tier 1 as Tier 3):**
+- Misses opportunity
+- Poor adoption
+- Competitive disadvantage
+
+### Flexibility
+
+**Adjust tier based on:**
+- Company stage (early vs. mature)
+- Market position (leader vs. challenger)
+- Resources available
+- Strategic importance
+
+### Communication
+
+**Be explicit with stakeholders:**
+- "This is a Tier 2 launch, so we'll do X but not Y"
+- Set clear expectations upfront
+- Document tier decision and reasoning
+
+---
+
+## Summary
+
+Use launch tiers to:
+1. **Match effort to impact**
+2. **Set stakeholder expectations**
+3. **Allocate resources efficiently**
+4. **Maintain consistency**
+5. **Maximize ROI**
+
+**Remember:** A well-executed Tier 2 launch beats a poorly-executed Tier 1.

+# Developer Product Metrics
+
+Comprehensive guide to measuring success for technical products, developer tools, and APIs.
+
+---
+
+## Why Developer Metrics Are Different
+
+Developer products have unique characteristics:
+- **High technical barriers** to adoption
+- **Longer evaluation** periods
+- **Community-driven** growth
+- **Usage-based** pricing models
+- **Quality over quantity** (one great developer > 100 casual users)
+
+Traditional B2B SaaS metrics don't always apply directly.
+
+---
+
+## The Developer Funnel
+
+```
+Awareness → Interest → Evaluation → Activation → Engagement → Retention → Monetization
+```
+
+Each stage has specific metrics.
+
+---
+
+## 1. Awareness Metrics
+
+### Top-of-Funnel
+
+**Website Traffic:**
+- Documentation page views
+- Landing page visits
+- Blog traffic
+- GitHub repository views
+
+**Search & Discovery:**
+- Organic search rankings (for key terms)
+- GitHub stars
+- Stack Overflow mentions
+- Social media mentions
+
+**Community Presence:**
+- Discord/Slack members
+- Reddit subscribers
+- Newsletter subscribers
+- Conference attendance
+
+**Targets (vary by company):**
+- 50K monthly docs views (early stage)
+- 500K monthly docs views (growth stage)
+- 1K+ GitHub stars (open source component)
+
+---
+
+## 2. Interest Metrics
+
+### Consideration Stage
+
+**Engagement:**
+- Time on documentation
+- Pages per session
+- Video views (tutorials)
+- GitHub README views
+
+**Content Consumption:**
+- Blog post reads
+- Tutorial completion rate
+- Demo video watch time
+- Webinar registrations
+
+**Social Proof:**
+- Case study views
+- Customer testimonials read
+- Comparison page visits
+
+**Targets:**
+- 5+ minute average session duration
+- 4+ pages per session
+- 50%+ video completion rate
+
+---
+
+## 3. Evaluation Metrics
+
+### Trial/Sandbox Stage
+
+**Sign-Up:**
+- Developer sign-ups
+- API key requests
+- Sandbox activations
+- Free tier activations
+
+**Time to Value:**
+- **Time to first API call** (target: < 10 minutes)
+- **Time to "Hello World"** (target: < 15 minutes)
+- **Time to integration** (target: < 1 hour)
+
+**Documentation Engagement:**
+- Getting started guide views
+- Code sample copies
+- SDK downloads
+- Postman collection imports
+
+**Targets:**
+- 1K+ sign-ups per month (early stage)
+- 60% make first API call within 24 hours
+- 10 minutes median time to first call
+
+---
+
+## 4. Activation Metrics
+
+### First Value Realized
+
+**Critical Activation Events:**
+- **First successful API call**
+- **First integration deployed**
+- **First production request**
+- **SDK installed and used**
+- **Sandbox → production migration**
+
+**Activation Rate:**
+```
+Activation Rate = (Users who complete activation event) / (Total sign-ups)
+```
+
+**Depth of Activation:**
+- Features explored
+- Endpoints called
+- SDKs used
+- Integrations enabled
+
+**Targets:**
+- 50-70% activation rate (first API call)
+- 30-40% activation rate (production deployment)
+- 80%+ complete getting started guide
+
+---
+
+## 5. Engagement Metrics
+
+### Active Usage
+
+**Daily/Weekly/Monthly Active Developers (DAD/WAD/MAD):**
+```
+DAD = Unique developers making API calls daily
+WAD = Unique developers active weekly
+MAD = Unique developers active monthly
+```
+
+**Stickiness:**
+```
+Stickiness = DAD / MAD
+```
+- Target: > 20% (good)
+- Target: > 40% (excellent)
+
+**API Usage:**
+- **Total API calls** per day/week/month
+- **API calls per developer**
+- **Endpoints used** per developer
+- **Error rate** (target: < 1%)
+
+**Feature Adoption:**
+- % of developers using key features
+- Time to feature adoption
+- Feature depth (how many features per user)
+
+**Targets:**
+- 40%+ stickiness (DAD/MAD)
+- 1K+ API calls per active developer per month
+- < 1% error rate
+- 3+ features adopted per developer
+
+---
+
+## 6. Retention Metrics
+
+### Developer Retention
+
+**Cohort Retention:**
+```
+Day 1 Retention = Developers active on Day 1 / Total sign-ups
+Day 7 Retention = Developers active on Day 7 / Total sign-ups
+Day 30 Retention = Developers active on Day 30 / Total sign-ups
+```
+
+**Typical Developer Product Retention:**
+- Day 1: 60-70%
+- Day 7: 30-50%
+- Day 30: 20-40%
+- Day 90: 15-30%
+
+**Why Developer Retention Is Lower:**
+- Evaluation period (many are just testing)
+- Project-based usage (finish project, stop using)
+- This is normal and expected
+
+**Churn Rate:**
+```
+Monthly Churn = Developers who stopped using / Active developers at month start
+```
+
+**Resurrection Rate:**
+```
+Resurrection = Churned developers who return / Total churned developers
+```
+
+**Targets:**
+- < 5% monthly churn (paid users)
+- 40%+ Day 7 retention
+- 25%+ Day 30 retention
+
+---
+
+## 7. Monetization Metrics
+
+### Revenue Metrics
+
+**Conversion Metrics:**
+```
+Free → Paid Conversion Rate = Paid users / Total active users
+```
+- Target: 3-10% (varies widely by product)
+
+**Revenue Metrics:**
+- **MRR** (Monthly Recurring Revenue)
+- **ARR** (Annual Recurring Revenue)
+- **ARPU** (Average Revenue Per User)
+- **Net Revenue Retention** (NRR)
+
+**Usage-Based Pricing Metrics:**
+- **Average API calls per paid user**
+- **Tier distribution** (how many in each pricing tier)
+- **Upgrade rate** (free → paid, basic → pro)
+- **Expansion revenue** (existing customers spending more)
+
+**Targets:**
+- 5%+ free-to-paid conversion
+- 110%+ Net Revenue Retention
+- $50-$500 ARPU (varies by product)
+
+---

+- **Search success** rate (did they find what they needed?)
+- **Time on page** (too short = unclear, too long = can't find)
+- **Bounce rate** on docs
+- **Feedback** (thumbs up/down on docs pages)
+
+**Targets:**
+- 90%+ search success rate
+- < 40% bounce rate on docs

+
+---
+
+## Setting Targets
+
+### Early Stage (0-1 year)
+
+Focus on **activation** and **engagement**:
+- Sign-ups: 1K-10K/month
+- Activation: 50%+
+- MAD: 500-5K
+- Day 7 Retention: 30%+
+
+### Growth Stage (1-3 years)
+
+Focus on **scale** and **retention**:
+- Sign-ups: 10K-50K/month
+- MAD: 10K-100K
+- Day 30 Retention: 25%+
+- Free→Paid: 5%+
+
+### Mature Stage (3+ years)
+
+Focus on **efficiency** and **expansion**:
+- MAD: 100K+
+- NRR: 110%+
+- ARPU: Increasing
+- CAC Payback: < 12 months
+
+---
+
+## Common Pitfalls
+
+### Vanity Metrics
+
+**Avoid:**
+- Total registered users (most are inactive)
+- Total API calls (could be from one user)
+- GitHub stars alone (may not use product)
+
+**Focus on:**
+- Active users (making API calls)
+- Retained users (coming back)
+- Engaged users (using multiple features)
+
+### Wrong Benchmarks
+
+Don't compare developer product metrics to:
+- B2C social apps (much higher DAU/MAU)
+- Enterprise SaaS (lower volume, higher ACV)
+- E-commerce (transactional, not sustained use)
+
+Use developer product benchmarks instead.
+
+---
+
+## Summary: Key Metrics to Track
+
+**Must Track:**
+1. Monthly Active Developers (MAD)
+2. Activation Rate (first API call)
+3. Day 7 & Day 30 Retention
+4. Stickiness (DAD/MAD)
+5. API Error Rate
+6. NPS
+
+**Should Track:**
+7. Free → Paid Conversion
+8. Time to First API Call
+9. Documentation Effectiveness
+10. Support Ticket Volume
+
+**Nice to Have:**
+11. GitHub Stars/Activity
+12. Community Engagement
+13. Social Sentiment
+14. Feature Adoption Depth
+
+Start with the must-track metrics, then expand.
+
+---
+
+## Developer Metric Formulas
+
+Quick reference:
+
+```
+Activation Rate = Activated Users / Sign-ups
+Stickiness = DAD / MAD
+Churn Rate = Users Lost / Total Users
+NRR = (MRR + Expansion - Churn) / Starting MRR
+LTV = ARPU / Churn Rate
+CAC Payback = CAC / (ARPU * Gross Margin)
+```
+
+**Remember:** Metrics should drive action, not just reporting. If a metric doesn't change behavior, don't track it.

+## Risk Management Frameworks
+
+### The 1% Rule (Recommended for Most Traders)
+**Never risk more than 1% of account on single trade**
+
+**Example:**
+- Account size: $50,000
+- Maximum risk per trade: $500 (1%)
+- Stock entry: $100
+- Stop-loss: $98
+- Risk per share: $2
+- Position size: $500 / $2 = 250 shares
+- Total position: $25,000 (50% of account)
+- Actual risk: $500 (1% of account)
+
+**Benefits:**
+- Can survive 20+ consecutive losses
+- Removes emotion from sizing
+- Consistent risk across trades
+- Protects capital
+
+### The 2R Minimum Rule
+**Only take trades with 2:1 reward-to-risk or better**
+
+**Example:**
+- Entry: $100
+- Stop: $98 (risk = $2)
+- Target: $104 (reward = $4)
+- R:R = 2:1 ✅
+
+**Why it matters:**
+- Can be profitable with 40% win rate
+- Forces selective trading
+- Improves overall edge
+
+### Maximum Drawdown Limit
+**Hard stop trading if down X% from peak**
+
+**Recommendations:**
+- Conservative: 10% drawdown → stop trading
+- Moderate: 15% drawdown → stop trading
+- Aggressive: 20% drawdown → stop trading
+
+**When hit:**
+1. Stop trading immediately
+2. Review all trades
+3. Identify mistakes
+4. Paper trade until recovered mentally
+5. Resume with reduced size

+
+## Position Sizing Formulas
+
+### Fixed Dollar Risk
+```
+Position Size = Account Risk $ / (Entry - Stop)
+
+Example:
+- Account: $50,000
+- Risk per trade: $500 (1%)
+- Entry: $100
+- Stop: $97
+- Risk per share: $3
+- Shares: $500 / $3 = 166 shares
+```
+
+### Fixed Percentage Risk
+```
+Position Size = (Account × Risk %) / (Entry - Stop)
+
+Example:
+- Account: $50,000
+- Risk: 1%
+- Entry: $50
+- Stop: $48
+- Risk per share: $2
+- Shares: ($50,000 × 0.01) / $2 = 250 shares
+```
+
+### Kelly Criterion (Advanced)
+```
+Position Size % = (Win Rate × Avg Win - Loss Rate × Avg Loss) / Avg Win
+
+Example:
+- Win rate: 55%
+- Avg win: $500
+- Loss rate: 45%
+- Avg loss: $300
+- Kelly: (0.55 × $500 - 0.45 × $300) / $500 = 28%
+- Use 1/4 Kelly = 7% position size (conservative)
+```
+
+**Warning:** Kelly can be aggressive, use fractional Kelly
+

+# Risk Management for Traders
+
+The single most important factor determining trading success.
+
+---
+
+## Why Risk Management Matters
+
+**The brutal truth:**
+- 90% of traders lose money
+- Most blow up their accounts
+- #1 reason: Poor risk management
+
+**What separates winners from losers:**
+- NOT better analysis
+- NOT better indicators  
+- NOT market prediction
+- **Risk management and discipline**
+
+**Your job as a trader:**
+- Protect capital FIRST
+- Make money SECOND
+
+---
+
+## The 1% Rule
+
+**Never risk more than 1% of account on single trade**
+
+### Why 1%?
+
+**Survival math:**
+- 10 losses in a row = -10% drawdown
+- 20 losses in a row = -20% drawdown
+- Still in the game
+
+**Compare to 5% risk:**
+- 10 losses in a row = -50% drawdown
+- Need 100% return just to break even
+- Likely game over
+
+### How to Calculate
+
+```
+Risk Amount = Account Size × 0.01
+
+Example:
+$50,000 account × 1% = $500 max risk per trade
+```
+
+### Position Sizing with 1% Rule
+
+```
+Shares = Risk Amount / (Entry - Stop)
+
+Example:
+- Account: $50,000
+- Risk: $500 (1%)
+- Entry: $100
+- Stop: $98
+- Risk per share: $2
+- Position: $500 / $2 = 250 shares
+```
+
+**Key insight:** Position SIZE changes, but RISK stays constant
+
+---
+
+## Daily Loss Limits
+
+**Hard stop when you hit daily loss limit**
+
+### Recommended Limits
+
+| Trader Type | Daily Loss Limit |
+|-------------|------------------|
+| Conservative | -1% |
+| Moderate | -2% |
+| Aggressive | -3% |
+
+### Why Daily Limits Matter
+
+**Prevents:**
+- Revenge trading
+- Emotional spirals
+- Blowup days
+- Tilt-induced disasters
+
+**Example:**
+- $50,000 account
+- 2% daily limit = -$1,000
+- Hit limit → DONE for the day
+- No exceptions
+
+### What to Do When Hit
+
+1. Close ALL positions
+2. Step away from computer
+3. Physical activity (walk/exercise)
+4. Review trades later (not now)
+5. Resume next day with clear head
+
+**Remember:** There's always tomorrow
+
+---
+
+## Maximum Drawdown
+
+**Stop trading at X% drawdown from peak**
+
+### Recommended Limits
+
+- Conservative: 10%
+- Moderate: 15%
+- Aggressive: 20%
+
+### When Hit
+
+1. **STOP trading immediately**
+2. Take minimum 1 week break
+3. Full trade review
+4. Identify systematic issues
+5. Paper trade only
+6. Return with reduced size
+
+### Why This Matters
+
+**Psychology of drawdown:**
+- -10% requires +11% to recover
+- -20% requires +25% to recover
+- -50% requires +100% to recover
+
+**Each % down becomes harder to recover**
+
+---
+
+## Risk:Reward Ratios
+
+**Only take trades with favorable R:R**
+
+### Minimum Standards
+
+**Conservative:** 3:1
+**Moderate:** 2:1
+**Aggressive:** 1.5:1
+
+### The Math
+
+With 2:1 R:R, you can be profitable at 40% win rate:
+
+```
+10 trades:
+- 4 wins × 2R = +8R
+- 6 losses × 1R = -6R
+- Net: +2R profit
+```
+
+### How to Calculate
+
+```
+R = Risk (Entry - Stop)
+Reward = Target - Entry
+
+R:R = Reward / Risk
+
+Example:
+- Entry: $100
+- Stop: $98 (Risk = $2)
+- Target: $106 (Reward = $6)
+- R:R = $6 / $2 = 3:1 ✓
+```
+
+**Rule:** If R:R < your minimum → SKIP THE TRADE
+
+---
+
+## Position Sizing Methods
+
+### 1. Fixed Dollar Risk (Recommended)
+
+**Same dollar risk every trade**
+
+```
+Shares = Risk $ / (Entry - Stop)
+```
+
+**Pros:**
+- Simple and consistent
+- Easy to track
+- Protects capital
+
+**Cons:**
+- Doesn't scale with wins/losses
+
+---
+
+### 2. Fixed Percentage Risk
+
+**Same % risk every trade**
+
+```
+Shares = (Account × Risk %) / (Entry - Stop)
+```
+
+**Pros:**
+- Scales with account
+- Compounds wins
+- Simple
+
+**Cons:**
+- Also compounds losses
+
+---
+
+### 3. Volatility-Based (ATR)
+
+**Position size based on volatility**
+
+```
+Risk $ / (ATR × Multiplier)
+```
+
+**Pros:**
+- Adapts to market conditions
+- Prevents whipsaw
+
+**Cons:**
+- More complex
+- Requires calculation
+
+---
+
+### 4. Kelly Criterion (Advanced)
+
+**Optimal position sizing based on edge**
+
+```
+Kelly % = (Win Rate × Avg Win - Loss Rate × Avg Loss) / Avg Win
+```
+
+**WARNING:**
+- Can be very aggressive
+- Use fractional Kelly (1/4 or 1/2)
+- Only for experienced traders
+- Requires accurate statistics
+
+---
+
+## Stop-Loss Strategies
+
+### Never Trade Without Stops
+
+**Why stops are mandatory:**
+- Limits losses
+- Removes emotion
+- Protects from disasters
+- Enables risk calculation
+
+**No exceptions. Ever.**
+
+### Stop-Loss Methods
+
+**1. Fixed Percentage**
+- X% below entry
+- Simple and clear
+- Example: 2% below entry
+
+**2. Technical Level**
+- Below support
+- Below swing low
+- Makes logical sense
+
+**3. ATR-Based**
+- 1.5-2× Average True Range
+- Adapts to volatility
+- Prevents whipsaw
+
+**4. Time Stop**
+- Exit if no progress in X days
+- Frees capital
+- Cuts losers
+
+### Stop-Loss Rules
+
+**✓ DO:**
+- Set stop BEFORE entry
+- Use actual stop orders (not mental)
+- Place stops at logical levels
+- Honor stops always
+
+**✗ NEVER:**
+- Move stop further from entry
+- Remove stop "just this once"
+- Use mental stops
+- Hope price comes back
+
+---
+
+## Position Concentration
+
+**Don't put all eggs in one basket**
+
+### Maximum Position Limits
+
+**Single position:**
+- Conservative: 10% of account
+- Moderate: 20% of account
+- Aggressive: 30% of account
+
+**Sector exposure:**
+- Maximum 30-40% in single sector
+- Diversify across sectors
+- Correlation matters
+
+**Total exposure:**
+- Day trading: 100% (close daily)
+- Swing trading: 60-80%
+- Position trading: Varies
+
+### Why Concentration Matters
+
+**Example:**
+- 50% in one position
+- Stock drops 20%
+- Account drops 10%
+- Hard to recover
+
+**Better:**
+- 10% in one position
+- Stock drops 20%
+- Account drops 2%
+- Manageable
+
+---
+
+## Correlation Risk
+
+**Avoid correlated positions**
+
+### Understanding Correlation
+
+**High correlation example:**
+- Long tech stock A
+- Long tech stock B
+- Both move together
+- Double exposure to tech risk
+
+**Better diversification:**
+- Different sectors
+- Different market caps
+- Different strategies
+- True diversification
+
+---
+
+## Leverage and Margin
+
+**Leverage amplifies BOTH gains and losses**
+
+### Margin Risk
+
+**2:1 Margin:**
+- 50% loss = margin call
+- Forced liquidation
+- Game over
+
+**Recommended:**
+- Use margin sparingly
+- Never max out margin
+- Maintain buffer
+- Understand margin requirements
+
+### Options Leverage
+
+**Options can expire worthless**
+- 100% loss possible
+- Time decay (theta)
+- Volatility risk (vega)
+- Requires different risk management
+
+**Options risk limit:**
+- Max 5-10% of account in options
+- Treat each option as high risk
+- Never bet the farm
+
+---
+
+## Risk Management Checklist

+**Capital preservation rules:**
+
+1. **Never go all-in**
+   - Keep reserves
+   - Opportunities come again
+
+2. **Accept losses quickly**
+   - Small losses are OK
+   - Don't let small become big
+
+3. **Don't average down**
+   - Adding to losers doubles risk
+   - Compounds mistakes
+
+4. **Take breaks after losses**
+   - Prevent revenge trading
+   - Clear your head
+
+5. **Reduce size in drawdown**
+   - Trade smaller when losing
+   - Build confidence back
+
+---
+
+## Common Risk Management Mistakes
+
+### ❌ Fatal Errors
+
+**1. No stop-loss**
+Result: One trade wipes account
+
+**2. Risk too much per trade**
+Result: Few losses = blown account
+
+**3. Moving stops**
+Result: Invalidates risk management
+
+**4. Revenge trading**
+Result: Emotional decisions, bigger losses
+
+**5. Averaging down**
+Result: Doubling down on mistakes
+
+**6. Over-leveraging**
+Result: Margin call, forced exit
+
+**7. Ignoring correlation**
+Result: Concentrated risk in disguise
+
+### ✓ Best Practices
+
+**1. Consistent position sizing**
+Same risk every trade
+
+**2. Hard daily loss limits**
+Stop when hit, no exceptions
+
+**3. Honest stop placement**
+Logical levels, not wishes
+
+**4. R:R minimum**
+Quality over quantity
+
+**5. Diversification**
+Don't concentrate risk
+
+**6. Regular reviews**
+Track and improve
+
+---
+
+## Risk vs Reward Balance
+
+**High Probability vs High R:R**
+
+### High Win Rate (60-70%)
+- Smaller R:R (1.5:1)
+- More trades
+- Steady equity curve
+- Example: Mean reversion
+
+### High R:R (3:1+)
+- Lower win rate (30-40%)
+- Fewer trades
+- Volatile equity curve
+- Example: Trend following
+
+**Both can be profitable if managed correctly**
+
+---
+
+## Position Sizing Examples
+
+### Example 1: Moderate Risk
+
+```
+Account: $50,000
+Risk per trade: 1% = $500
+Entry: $50
+Stop: $48
+Risk per share: $2
+
+Position: $500 / $2 = 250 shares
+Position value: $12,500 (25% of account)
+Actual risk: $500 (1% of account)
+```
+
+### Example 2: Tight Stop
+
+```
+Account: $50,000
+Risk per trade: 1% = $500
+Entry: $100
+Stop: $99
+Risk per share: $1
+
+Position: $500 / $1 = 500 shares
+Position value: $50,000 (100% of account)
+Actual risk: $500 (1% of account)
+```
+
+**Key:** Position SIZE varies, but RISK stays constant
+
+---
+
+## Emergency Procedures
+
+### When Things Go Wrong
+
+**Circuit breaker triggered:**
+1. Stop trading immediately
+2. Close positions if possible
+3. Assess damage
+4. Don't panic trade
+
+**Flash crash:**
+1. Don't chase
+2. Check your stops
+3. Wait for stability
+4. Review risk exposure
+
+**Account down big:**
+1. STOP trading
+2. Take mandatory break
+3. Full review
+4. Return with smaller size
+

+## Discipline Framework
+
+### Pre-Trade
+
+**Checklist before EVERY trade:**
+- [ ] Meets setup criteria?
+- [ ] R:R acceptable?
+- [ ] Position size calculated?
+- [ ] Stop-loss identified?
+- [ ] Within daily risk limit?
+- [ ] Calm and focused?
+- [ ] Following plan?
+
+**If ANY "no" → Don't trade**
+
+### During Trade
+
+**Rules while in position:**
+- Check portfolio 2-3x max per day
+- Don't watch every tick
+- Trust your stop
+- Don't interfere unless rule-based
+- Avoid social media/chat
+
+### Post-Trade
+
+**After every trade:**
+- Log trade in journal
+- Note what went right/wrong
+- Capture lessons
+- Review compliance
+- Don't dwell on outcome
+
+---
+
+## Emotional State Management
+
+### Pre-Market Routine
+
+**Daily checklist (15-30 min):**
+- [ ] Adequate sleep (7+ hours)?
+- [ ] Hydrated and fed?
+- [ ] Calm and centered?
+- [ ] No major life stress?
+- [ ] Ready to accept losses?
+- [ ] Following plan today?
+
+**If feeling off → Reduce size or skip day**
+
+### Recognizing Tilt
+
+**Warning signs:**
+- Increasing position size
+- Abandoning stops
+- Taking marginal setups
+- Checking P&L constantly
+- Feeling anxious/desperate
+- Anger at market
+- Rushing into trades
+
+**When tilting:**
+1. STOP immediately
+2. Close positions
+3. Walk away
+4. Physical reset (exercise)
+5. Don't resume until calm
+
+### Cool-Down Periods
+
+**After any loss:**
+- Minimum 15-30 minutes
+- Walk, breathe, reset
+- Review trade objectively
+- Return only when calm
+
+**After 2 consecutive losses:**
+- 1 hour minimum
+- Full review of both trades
+- Confirm plan compliance
+- Reduce size if continuing
+
+**After 3 consecutive losses:**
+- DONE for the day
+- Full day review tomorrow
+- Don't force it
+- Tomorrow is new day
+
+---
+
+## Mindset Shifts
+
+### From Outcome to Process
+
+**Wrong focus:**
+- "I need to make $X today"
+- "I need to win this trade"
+- "I can't afford to lose"
+
+**Right focus:**
+- "Did I follow my plan?"
+- "Was my risk management correct?"
+- "What can I learn?"
+
+### From Prediction to Probabilities
+
+**Wrong thinking:**
+- "This trade WILL work"
+- "I know what market will do"
+- "I can't be wrong"
+
+**Right thinking:**
+- "This has good probability"
+- "I don't know, but R:R is good"
+- "I can be wrong and still profitable"
+
+### From Money to Process
+
+**Wrong focus:**
+- Daily P&L
+- "How much did I make?"
+- Comparing to others
+
+**Right focus:**
+- Plan compliance
+- "Did I execute well?"
+- Personal improvement
+
+---
+
+## Handling Losses
+
+### Accept Losses as Business Cost
+
+**Truth:**
+- Losses are inevitable
+- Even 70% win rate = 30% losses
+- Losses are data, not failure
+- Cost of doing business
+
+**Mindset:**
+- "This is expected"
+- "I planned for this"
+- "On to next trade"
+- No emotion
+
+### Learn from Every Loss
+
+**After each loss ask:**
+- Did I follow my plan?
+- Was setup valid?
+- Was risk management correct?
+- What can I improve?
+
+**Categories of losses:**
+1. **Good loss:** Followed plan, just didn't work
+2. **Bad loss:** Broke rules
+3. **Learning loss:** New insight gained
+
+**Good losses are OK. Learn from bad ones.**
+
+---
+
+## Handling Wins
+
+### Don't Get Overconfident
+
+**After big win:**
+- Resist urge to increase size
+- Follow plan as always
+- One win doesn't mean edge
+- Stay humble
+
+### Avoid Euphoria
+
+**Warning signs:**
+- Feeling invincible
+- "I figured it out"
+- Itching to trade more
+- Looking for any setup
+
+**Remedy:**
+- Stick to plan
+- Take break if needed
+- Remember: regression to mean
+- Past performance ≠ future
+
+---

+
+---
+
+## ⚠️ CRITICAL DISCLAIMER
+
+This trading plan is a personal framework for managing trading decisions. It does NOT constitute financial advice. Trading involves substantial risk of loss. Only trade with capital you can afford to lose.
+
+---
+
+## 1. Trading Goals & Philosophy
+
+### Financial Goals
+- **Account Size:** \$${ACCOUNT_SIZE}
+- **Monthly Target:** ${MONTHLY_TARGET:-TBD}%
+- **Focus:** Consistent execution over returns
+
+### Time Commitment
+- **Daily Time:** ${TIME_COMMIT:-TBD} hours
+- **Trading Style:** ${TRADING_STYLE}
+- **Market Hours:** [Specify your trading hours]
+
+### Trading Philosophy
+[Write your personal trading philosophy - what you believe about markets, why you trade this way, your edge]
+
+**Example:**
+"I believe markets trend, and I have an edge in identifying early-stage trends with technical analysis. My success comes from discipline, not prediction. I focus on process over profits."
+
+---
+
+## 2. Risk Management (MOST IMPORTANT)
+
+### Position Sizing Rules
+
+**Risk Per Trade: ${RISK_PER_TRADE}%**
+- Maximum risk per position: \$${DOLLAR_RISK}
+- NEVER exceed this amount on a single trade
+- Calculate position size BEFORE entering
+
+**Position Size Formula:**
+\`\`\`
+Shares = Risk Amount / (Entry Price - Stop Price)
+      = \$${DOLLAR_RISK} / (Entry - Stop)
+\`\`\`
+
+**Example:**
+- Entry: \$100
+- Stop: \$98
+- Risk per share: \$2
+- Position: \$${DOLLAR_RISK} / \$2 = $(echo "scale=0; $DOLLAR_RISK / 2" | bc) shares
+
+### Daily Loss Limit
+
+**HARD STOP at -${DAILY_LOSS_LIMIT}% daily loss**
+
+- Maximum daily loss: \$$(echo "scale=2; $ACCOUNT_SIZE * $DAILY_LOSS_LIMIT / 100" | bc)
+- When hit: STOP TRADING immediately
+- Close all positions
+- Step away from computer
+- Review what went wrong
+- Resume next day with clear head
+
+**No exceptions. This rule protects your account.**
+
+### Maximum Drawdown
+
+**Break from trading at -${MAX_DRAWDOWN}% drawdown**
+
+- Stop trading if account drops ${MAX_DRAWDOWN}% from peak
+- Take minimum 1 week break
+- Paper trade only
+- Review all trades
+- Identify systematic issues
+- Resume only when mentally ready
+
+### Risk:Reward Requirements
+
+**Minimum R:R: ${MIN_RR}**

+- Quality over quantity
+
+### Stop-Loss Rules
+
+**EVERY trade MUST have a stop-loss**
+
+- **Method:** ${STOP_METHOD}

+## Appendix A: Position Size Calculator
+
+**Quick reference:**
+
+| Entry - Stop | Position Size (for \$${DOLLAR_RISK} risk) |
+|--------------|-------------------------------------------|
+| \$1 | $(echo "scale=0; $DOLLAR_RISK / 1" | bc) shares |
+| \$2 | $(echo "scale=0; $DOLLAR_RISK / 2" | bc) shares |
+| \$3 | $(echo "scale=0; $DOLLAR_RISK / 3" | bc) shares |
+| \$5 | $(echo "scale=0; $DOLLAR_RISK / 5" | bc) shares |
+
+**Formula:** Shares = \$${DOLLAR_RISK} / (Entry - Stop)
