#### Planning & Strategy
- **`generate-plan`** - Generate detailed implementation plans for development tasks
- **`strategic-plan`** - Create high-level strategic roadmaps for complex features
- **`review-approach`** - Review and validate implementation approaches before coding

#### Analysis & Understanding  
- **`analyze-codebase`** - Analyze codebase structure and patterns before making changes
- **`explain-concept`** - Get comprehensive explanations of technical concepts and patterns
- **`compare-technologies`** - Compare different technologies, frameworks, or approaches

#### Development Support

## Prerequisites

- Node.js 18+ and pnpm
- [Gemini CLI](https://github.com/google-gemini/gemini-cli) installed and configured
- Valid Google AI API credentials for Gemini access
- Claude Code CLI

## Installation

1. Clone the repository:
   ```bash
   git clone https://github.com/yourusername/gemini-mcp.git
   cd gemini-mcp
   ```

2. Install dependencies:
   ```bash
   pnpm install
   ```

3. Build the project:
   ```bash
   pnpm build
   ```

4. Configure Gemini CLI with your API credentials:
   ```bash
   gemini auth login
   ```

## Usage

### Running the Server

For development:
```bash
pnpm dev
```

For production:
```bash
pnpm start
```

### Integration with Claude Code

Add this server to your Claude Code configuration:

```bash
claude mcp add gemini-mcp node /path/to/dist/index.js
```

### Adding custom commands 

Copy the content of claude-commands to your .claude/commands folder

```bash
cp claude-commands/* ./claude/commands
```

### Using the Tools

Once configured, you can use the tools directly in Claude Code:

#### Planning and Strategy
```
/plan Add user authentication with JWT tokens
/strategy Real-time chat system | WebSocket connections, message persistence, user presence
/review I plan to use Redux Toolkit with RTK Query for state management
```

#### Analysis and Understanding
```
/analyze [select files/folders to analyze their architecture]
/explain event loop in Node.js and asynchronous operations
/compare React vs Vue for building a dashboard application
```

#### Development Support
```
/consult How should I structure error handling in my React app?
/tests UserAuthenticationService with login, logout, and password reset methods
/docs REST API endpoints for user management system
/debug TypeError: Cannot read property 'map' of undefined in React component
```

### Available Scripts

- `pnpm dev` - Run in development mode with hot reload
- `pnpm build` - Compile TypeScript and auto-generate commands
- `pnpm generate-commands` - Generate claude-commands from tool configurations
- `pnpm start` - Run the compiled server
- `pnpm typecheck` - Run TypeScript type checking
- `pnpm clean` - Remove build artifacts

### Adding New Tools

1. Add new prompt template in `src/prompts.ts`
2. Add tool configuration in `src/tools.ts` 
3. Implement the method in `src/gemini.ts`
4. Add case in `src/server.ts` switch statement
5. Run `pnpm generate-commands` to auto-create documentation
6. Update this README if needed

The system automatically generates claude-commands from tool configurations, ensuring consistency.
