Summary

  • Adds comprehensive CLI tool for hook discovery and management
  • Makes the hook system fully transparent and discoverable
  • Answers "where are all my hooks?" with simple commands

Features

CLI Commands

  • ./claude-hooks list - Show all hooks in the repository with colors and details
  • ./claude-hooks list --json - Machine-readable JSON output for tooling
  • ./claude-hooks explain <file> - Show which hooks apply to a specific file
  • ./claude-hooks validate - Validate all configuration files

Implementation Details

  • Hierarchical configuration system with inheritance
  • File pattern and tool-specific filtering
  • Priority-based execution order
  • Colored terminal output for better readability
  • Built-in configuration validation
  • Convenient wrapper script in project root

Test plan

  • Test list command shows all hooks
  • Test list --json provides machine-readable output
  • Test explain command shows hooks for specific files
  • Test validate command checks configuration integrity
  • Verify colored output in terminal
  • Confirm wrapper script works from project root

feat: create portable bash-only code quality hooks
6a4cb46 
- Created pure bash hooks with zero dependencies (no Node.js required)
- Added multi-language support (TypeScript, JavaScript, Python, Ruby)
- Direct bash execution in settings.json for better portability
- Simple installation script for easy setup in any project
- Removed complex TypeScript universal-hook dependency
- Works in Python, Ruby, Go, and other non-JS projects

Key improvements:
- No npm or Node.js required
- Works with any language project
- Minimal footprint (~400 lines total)
- Easy to customize and extend

cleanup: remove Node.js/TypeScript dependencies
f05340d 
- Removed entire src/ directory (TypeScript source)
- Removed entire lib/ directory (compiled JavaScript)
- Removed node_modules/ and package files
- Removed old universal-hook system files
- Removed obsolete hook configurations
- Kept only portable bash hooks

This reduces the codebase to just essential bash scripts:
- No Node.js required
- No compilation needed
- No npm dependencies
- Pure bash implementation
