This helps understand current project state across git, dependencies, and tests.
</objective>

<context>
- Git: ! `git status --short`
- Node: ! `npm list --depth=0 2>/dev/null | head -20`
- Tests: ! `npm test -- --listTests 2>/dev/null | wc -l`
</context>

<process>
1. Analyze git status for uncommitted changes

</success_criteria>
```

Multiple bash commands load environment state.

### Pattern: Conditional Execution

```markdown
---
description: Deploy if tests pass
allowed-tools: Bash(npm test:*), Bash(npm run deploy:*)
---

<objective>
Deploy to production only if all tests pass.

This ensures deployment safety through automated testing gates.
</objective>

<context>
Test results: ! `npm test`
</context>

<process>
1. Review test results
2. If all tests passed, proceed to deployment
3. If any tests failed, report failures and abort

```

Sequential steps in single command.

## Tool Restriction Patterns

### Pattern: Git-Only Command

```markdown
---
allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git diff:*), Bash(git commit:*)
description: Git workflow command
---

<objective>
Perform git operations safely with tool restrictions.

This prevents running arbitrary bash commands while allowing necessary git operations.
</objective>

<context>
Current git state: ! `git status`
</context>

<process>
1. Review git status
2. Perform git operations
3. Verify changes
</process>

<success_criteria>
- Git operations completed successfully
- No arbitrary commands executed
- Repository state as expected
</success_criteria>
```

Prevents running non-git bash commands.

### Pattern: Read-Only Analysis

```markdown
---
allowed-tools: [Read, Grep, Glob]
description: Analyze codebase
argument-hint: [search pattern]
---

<objective>
Search codebase for pattern: $ARGUMENTS

This provides safe codebase analysis without modification or execution permissions.
</objective>

<process>
1. Use Grep to search for pattern across codebase
2. Analyze findings
3. Identify relevant files and code sections
4. Provide summary of results
</process>

<success_criteria>
- Pattern search completed
- All matches identified
- Relevant context provided
- No files modified
</success_criteria>
```

No write or execution permissions.

### Pattern: Specific Bash Commands

```markdown
---
allowed-tools: Bash(npm test:*), Bash(npm run lint:*)
description: Run project checks
---

<objective>
Run project quality checks (tests and linting).

This ensures code quality while restricting to specific npm scripts.
</objective>

<testing>
Tests: ! `npm test`
Lint: ! `npm run lint`
</testing>

<process>
1. Run tests and capture results
2. Run linting and capture results
3. Analyze both outputs
4. Report on pass/fail status
5. Provide specific failure details if any
</process>

<success_criteria>
- All tests passing
- No lint errors
- Clear report of results
- Or specific failures identified with details
</success_criteria>
```

Only allows specific npm scripts.

## Best Practices

### 1. Use Tool Restrictions for Safety

```yaml
# Git commands
allowed-tools: Bash(git add:*), Bash(git status:*)

# Analysis only
allowed-tools: [Read, Grep, Glob]

# Thinking only
allowed-tools: SequentialThinking
```

### 2. Load Dynamic Context When Needed

```markdown
Current state: ! `git status`
Recent activity: ! `git log --oneline -5`
```

### 3. Reference Files Explicitly

```markdown
Review @ package.json for dependencies
Check @ src/config/* for settings
```

### 4. Structure Complex Commands

```markdown
## Step 1: Analysis
[analysis prompt]

## Step 2: Implementation
[implementation prompt]

## Step 3: Verification
[verification prompt]
```

### 5. Use Arguments for Flexibility

```markdown
# Simple
Fix issue #$ARGUMENTS

# Positional
Review PR #$1 with priority $2

# File reference
Analyze @ $ARGUMENTS
```

## Anti-Patterns to Avoid

### ❌ No Description

```yaml
---
# Missing description field
---
```

### ❌ Overly Broad Tool Access

```yaml
# Git command with no restrictions
---
description: Create commit
---
```

Better:
```yaml
---
description: Create commit
allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*)
---
```

### ❌ Vague Instructions

```markdown
Do the thing for $ARGUMENTS
```

Better:
```markdown
Fix issue #$ARGUMENTS by:
1. Understanding the issue
2. Locating relevant code
3. Implementing solution
4. Adding tests
```

### ❌ Missing Context for State-Dependent Tasks

```markdown
Create a git commit
```

Better:
```markdown
Current changes: ! `git status`
Diff: ! `git diff`

Create a git commit for these changes
```
