Creating a new plugin

1. Create a directory under plugins/ with your plugin name (use kebab-case):

   plugins/my-plugin/
   ├── .claude-plugin/
   │   └── plugin.json
   ├── commands/
   │   └── my-command.md
   ├── evals/          # optional
   │   └── evals.json
   └── README.md
   

2. Define plugin.json with metadata:

   {
     "name": "my-plugin",
     "version": "1.0.0",
     "description": "What this plugin does",
     "author": "github.com/your-username"
   }
   

3. Add commands as Markdown files in commands/ with frontmatter:

   ---
   description: "What this command does"
   argument-hint: "[optional-args]"
   ---
   
   # Name
   ...
