+# TYPO3 DDEV Skill Refactoring Summary
+
+## Overview
+
+Refactored `SKILL.md` to follow skill-creator best practices, converting documentation-style sections into imperative directives that guide Claude's actions rather than describing what the skill does.
+
+## Skill-Creator Best Practices Applied
+
+### 1. Imperative/Infinitive Form
+**Principle**: Write instructions using verb-first, objective language (e.g., "To accomplish X, do Y") instead of second-person or descriptive language.
+
+**Before**: "Common issues and their solutions are documented..."
+**After**: "When encountering errors during setup or installation..."
+
+### 2. Action-Oriented Instructions
+**Principle**: Focus on WHAT to do and WHEN to do it, not just WHAT exists.
+
+**Before**: "The script validates: Docker daemon status, Docker CLI version..."
+**After**: "Run validation script: Execute `scripts/validate-prerequisites.sh` to check..."
+
+### 3. Integration Over Documentation
+**Principle**: Integrate communication guidelines into workflow steps instead of having separate style guides.
+
+**Before**: Separate "Communication Style" section listing style rules
+**After**: "Output Formatting Guidelines" section with actionable instructions
+
+## Detailed Changes
+
+### Section 1: Prerequisites Validation (lines 41-56)
+
+**Changes Made**:
+- Converted from descriptive ("The script validates:") to imperative ("Run validation script: Execute...")
+- Changed "For detailed prerequisite information including:" to "If validation fails: Consult..."
+- Added explicit action: "Report results: Display validation status..."
+
+**Why**: The original described what prerequisites exist; the refactored version instructs Claude on HOW to validate and WHAT to do if validation fails.
+
+---
+
+### Section 2: Error Handling (lines 514-524)
+
+**Original Structure**:
+```markdown
+## Error Handling
+
+Common issues and their solutions are documented in the troubleshooting guide.
+
+**Most frequent issues:**
+- Prerequisites not met
+- Port conflicts
+- TYPO3 installation failures
+
+See: `references/troubleshooting.md`
+```
+
+**Refactored Structure**:
+```markdown
+## Error Handling
+
+When encountering errors during setup or installation:
+
+1. Check error category: Identify if the error relates to...
+2. Consult troubleshooting guide: Read `references/troubleshooting.md`...
+3. Apply recommended solution: Follow the step-by-step resolution guide...
+4. For Windows/WSL2 environments: If error persists on Windows, consult...
+
+Report the error to the user with the specific solution being applied...
+```
+
+**Why**: Original listed what errors exist (descriptive). Refactored version instructs when and how to handle errors (imperative).
+
+---
+
+### Section 3: Advanced Configuration (lines 526-536)
+
+**Original Structure**:
+```markdown
+## Advanced Options
+
+For advanced configuration and optional features, see the comprehensive guide.
+
+**Available customizations:**
+- Custom PHP versions
+- Intelligent database selection
+- XDebug setup
+
+See: `references/advanced-options.md`
+```
+
+**Refactored Structure**:
+```markdown
+## Advanced Configuration
+
+When user requests customizations beyond the standard setup:
+
+1. Identify customization type: Determine if request involves...
+2. Consult advanced options guide: Read `references/advanced-options.md`...
+3. Present options to user: Show available choices...
+4. Apply configuration: Follow the templates and instructions...
+
+Offer customization options proactively when user mentions...
+```
+
+**Why**: Original described what options exist. Refactored version instructs WHEN to offer customizations and HOW to apply them.
+
+---
+
+### Section 4: Demo Content (lines 564-578)
+
+**Changes Made**:
+- Changed from "The Introduction Package provides..." to "When discussing testing capabilities with users, inform them that..."
+- Changed "What's Included:" bullet list to active voice with purpose (e.g., "for testing navigation")
+- Changed "Access:" to "Direct users to test their extension against this demo content at:"
+
+**Why**: Instructs Claude on WHEN to mention demo content and HOW to direct users to it, rather than just listing what exists.
+
+---
+
+### Section 5: Extension Auto-Configuration (lines 580-612)
+
+**Changes Made**:
+- Changed "For extensions requiring..." to "When user's extension requires..."
+- Changed "Use Cases for Auto-Configuration" to "Identify Configuration Needs by Extension Type"
+- Converted lists from descriptive to active voice with "configure:" prefix
+
+**Why**: Makes it clear this is guidance for Claude on identifying user needs and configuring accordingly.
+
+---
+
+### Section 6: Validation Checklist → Step 9: Verify Installation (lines 708-720)
+
+**Original Structure**:
+```markdown
+## Validation Checklist
+
+Before completing, verify:
+
+- [ ] All prerequisite checks passed
+- [ ] Extension metadata extracted correctly
+- [ ] User confirmed configuration values
+```
+
+**Refactored Structure**:
+```markdown
+### Step 9: Verify Installation
+
+After installation completes, perform these verification steps in order:
+
+1. Confirm prerequisites passed: Review output from Step 1...
+2. Verify extension metadata: Check that extracted values match...
+3. Test DDEV status: Run `ddev describe` to confirm...
+```
+
+**Why**: Checkbox lists are passive todo items. Numbered imperative steps are active instructions. Also integrated this as Step 9 in the workflow for better flow.
+
+---
+
+### Section 7: Communication Style → Output Formatting Guidelines (lines 722-729)
+
+**Original Structure**:
+```markdown
+## Communication Style
+
+- Use clear, concise language
+- Show progress indicators during long operations
+- Use emojis for visual clarity
+- Provide copy-pasteable commands
+```
+
+**Refactored Structure**:
+```markdown
+## Output Formatting Guidelines
+
+Throughout all steps, format output for clarity:
+- Use emojis for visual indicators: ✅ (success), ❌ (error)...
+- Display progress indicators during operations taking >5 seconds
+- Provide copy-pasteable command blocks with explanations
+```
+
+**Why**: Changed from describing a communication style to instructing how to format output. More specific and actionable.
+
+---
+
+### Section 8: Example Interaction (REMOVED)
+
+**Original**: Had an "Example Interaction" section showing sample user dialogue
+**Refactored**: Completely removed
+
+**Why**: According to skill-creator best practices, skills should provide instructions for Claude, not examples of what the skill does. The Step-by-Step Workflow already demonstrates usage.
+
+---
+
+## Impact Summary
+
+### What Changed
+1. ✅ All major sections converted from descriptive to imperative form
+2. ✅ Communication guidelines integrated into workflow
+3. ✅ Removed redundant "Example Interaction" section
+4. ✅ Validation checklist converted to procedural Step 9
+5. ✅ Error handling and advanced options now instruct WHEN and HOW
+
+### What Stayed the Same
+- Core workflow steps (Steps 1-8)
+- Configuration file templates
+- Reference file structure
+- Metadata (name, description, frontmatter)
+
+### Why This Matters
+
+**Before Refactoring**: Skill read like documentation ABOUT the skill
+**After Refactoring**: Skill reads like instructions FOR Claude
+
+This reduces confusion where Claude might output the skill's instructions verbatim to users, instead of using them as internal guidance to perform the task.
+
+## Skill-Creator Compliance Checklist
+
+✅ Written in imperative/infinitive form throughout
+✅ Action-oriented with clear triggers (When X, do Y)
+✅ References to resources include WHEN to use them
+✅ No second-person language ("you should")
+✅ No descriptive sections that should be directives
+✅ Communication style integrated into workflow
+✅ Validation converted from checklist to procedural steps
+
+## Testing Recommendations
+
+To verify the improvements work as intended:
+
+1. **Invoke the skill**: Run the typo3-ddev skill on a test project
+2. **Watch for output**: Claude should execute the workflow, NOT output the skill instructions
+3. **Check formatting**: Output should use emojis and formatting guidelines automatically
+4. **Verify error handling**: If an error occurs, Claude should consult troubleshooting.md and apply solutions
+5. **Test advanced options**: Request a custom PHP version and verify Claude follows the advanced configuration workflow
+
+## Next Steps
+
+1. ✅ Refactoring complete
+2. ⏳ Test skill with actual TYPO3 projects
+3. ⏳ Gather feedback on whether Claude uses instructions correctly
+4. ⏳ Iterate based on real-world usage
