daniel e5177fbe27 🤖 Complete Hook System Overhaul + AI Specification
✅ Fixed ALL remaining hooks (20 total):
- Updated post-tool/ and pre-tool/ hooks to Claude Code array format
- Fixed git-add-changes, format-javascript-files, format-python-files, run-tests-after-changes
- Fixed backup-before-edit, notify-before-bash

🧠 Added AI Hook Specification System:
- CLAUDE_HOOK_SPECIFICATION.md - Complete hook format guide for AI
- AI_HOOK_TEMPLATE.json - Structured template with examples for AI parsing
- HOOK_PATTERNS_COMPRESSED.json - Compressed patterns for rapid AI reference

📊 Technical Improvements:
- All 20 hooks now use proper array/matcher structure
- Regenerated components.json with corrected hook metadata
- Added comprehensive validation rules and anti-patterns
- Included environment variables and cross-platform compatibility guides

🎯 AI Context Enhancement:
- Future Claude Code sessions can reference these files for correct hook generation
- Compressed format optimizes AI parsing while maintaining completeness
- Common patterns and validation rules prevent structure errors

This hook creates a timestamped backup copy (filename.backup.timestamp) of any existing file before Claude modifies it. Provides a safety net to recover previous versions if needed. Only backs up existing files, includes error suppression to handle edge cases gracefully.",
