```

## Quick Start

```json
{
  "name": "my-plugin",
  "description": "Plugin description",
  "version": "1.0.0",
  "author": { "name": "Your Name" }
}
```

### 3. Add Components

- **Commands**: See [commands.md](references/commands.md)

- **Hooks**: See [hooks.md](references/hooks.md)
- **MCP Servers**: See [mcp.md](references/mcp.md)

      "source": "./my-plugin",
      "description": "Plugin description"
    }
  ]
