Quick Start

Using Existing Plugins

1. Clone this repository
2. Configure Claude Code to use this marketplace
3. Start using skills:

   # Go backend development
   /start-project my-backend-api
   /new-feature user-management
   
   # React frontend development
   /start-project my-react-app
   /new-component Button
   
   # Generate custom plugin for your project
   /analyze-project
   /generate-plugin
   

Creating Custom Plugins

Easy Way (Recommended): Use the plugin-helper plugin to generate a custom plugin for your project:

# Analyze your project
/analyze-project

# Review the analysis report
# Then generate the plugin
/generate-plugin

Manual Way:

1. Create a new directory under plugins/:

   mkdir -p plugins/my-plugin/.claude-plugin
   mkdir -p plugins/my-plugin/skills/my-skill
   

2. Add plugin metadata in .claude-plugin/plugin.json:

   {
     "name": "my-plugin",
     "description": "Description of what your plugin does",
     "version": "1.0.0"
   }
   

3. Create a skill in skills/my-skill/SKILL.md:

   ---
   description: Brief description
   ---
   
   Instructions for Claude when this skill is invoked.
   

4. Register the plugin in .claude-plugin/marketplace.json:

   {
     "plugins": [
       {
         "name": "my-plugin",
         "source": "./plugins/my-plugin",
         "description": "Description of what your plugin does"
       }
     ]
   }
