## 🔌 Plugin System

### Plugin Types

#### 1. Provider Plugins
Add new AI providers with custom logic:

```javascript
class CustomProvider {
  constructor(config) {
    this.apiBase = config.apiBase;
    this.models = config.models;
    this.pricing = config.pricing;
  }

  async createRequest(prompt, options) {
    // Custom request creation logic
  }

  async parseResponse(response) {
    // Custom response parsing
  }
}
```

#### 2. Hook Plugins
Execute code at specific routing points:

```javascript
class LoggingHook {
  get hooks() {
    return {
      'beforeRequest': async (req) => {
        console.log(`Request: ${req.method}`);
      },
      'afterRequest': async (req, response, latency) => {
        console.log(`Completed in ${latency}ms`);
      }
    };
  }
}
```

#### 3. Middleware Plugins
Add custom request/response processing:

```javascript
class RateLimitMiddleware {
  async middleware(req, res, next) {
    // Rate limiting logic
    await next();
  }
}
```

### Plugin Management

#### Create Plugin Scaffold
```bash
# Create provider plugin
ccr plugin create my-provider --type provider

# Create middleware plugin
ccr plugin create rate-limiter --type middleware --description "Rate limiting middleware"
```

#### Plugin Operations
```bash
# List loaded plugins
ccr plugin list

# Load plugin
ccr plugin load my-provider

# Unload plugin
ccr plugin unload my-provider

# Reload plugin (after changes)
ccr plugin reload my-provider

# Load all plugins
ccr plugin load-all
```

### Plugin Structure

```
plugins/my-provider/
├── plugin.json          # Plugin configuration
├── index.js              # Main plugin file
├── package.json          # Dependencies (optional)
└── README.md             # Documentation
```
