Development

This repository is a Plugin Factory. The plugins/ directory contains production-ready plugins that should NOT be modified for debugging purposes.

Setup

# Generate .claude/ files from plugins/
./scripts/dev-setup.sh

# Check current status
./scripts/dev-setup.sh --status

# Clean up generated files
./scripts/dev-setup.sh --clean

How it works:

• Generates .claude/settings.json from plugins/*/hooks/hooks.json
• Generates .claude/commands/ from plugins/*/commands/
• Replaces ${CLAUDE_PLUGIN_ROOT} with ${PWD}/plugins/<name>

After running dev-setup.sh, start claude to debug plugins.

Workflow

# 1. Initial setup
./scripts/dev-setup.sh

# 2. Modify files in plugins/
vim plugins/cc-version-updater/scripts/version-check.sh

# 3. Regenerate .claude/ files
./scripts/dev-setup.sh

# 4. Test with claude
claude

Testing

# Validate plugin structure
./scripts/validate-plugin.sh cc-version-updater

# Test hook script
./scripts/test-hook.sh cc-version-updater

Creating a New Plugin

1. Create plugin directory:

   mkdir -p plugins/my-plugin/.claude-plugin
   mkdir -p plugins/my-plugin/hooks
   mkdir -p plugins/my-plugin/scripts
   

2. Create plugin.json:

   {
     "name": "my-plugin",
     "version": "1.0.0",
     "description": "My awesome plugin",
     "hooks": "./hooks/hooks.json"
   }
   

3. Run dev-setup and test:

   ./scripts/dev-setup.sh
   claude
