- **Configurable Timeouts**: Environment-based timeout control (default: 30s)
- **Retry Conditions**: Smart retry on 5xx errors, 429 rate limits, and network issues
- **Circuit Breaking**: Graceful degradation when API is consistently failing
#### 🔐 **Enhanced Input Validation**
- **Early Sanitization**: Input cleaning before processing
- **Comprehensive Validation**:
- Query length limits (1000 chars max)
- Parameter type checking
- Date format validation
- Analysis mode validation
- Result count bounds checking
- **Security**: Removal of control characters and malicious input
#### 📊 **Structured Logging System**
- **JSON Formatted**: Machine-parseable logs with timestamps
- **Log Levels**: Error, warn, info, debug with contextual data
- **Performance Tracking**: Request duration, success rates, error details
- **Debugging**: Comprehensive error context for troubleshooting
### Phase 3: Advanced Features
#### 💾 **Intelligent Caching**
- **Comprehensive Analysis Cache**: Expensive analyses cached for 30 minutes
- **Memory Management**: LRU cache with size limits (100 items max)
- **TTL Control**: Automatic expiration and cleanup
- **Cache Keys**: Unique keys including all parameters for accuracy
#### 🏥 **Health Monitoring**
- **Health Check Tool**: New MCP tool for server diagnostics
- **Performance Metrics**:
- Uptime tracking
- Request count and success rates
- Error count and trends
- Cache utilization
- API connectivity status
- **Real-time Status**: Live health reporting with detailed breakdown
#### ⚙️ **Configuration Management**
- **Environment Variables**:
- `XAI_API_KEY`: API key (required)
- `GROK_TIMEOUT`: Request timeout in ms (default: 30000)
- `GROK_MAX_RETRIES`: Retry attempts (default: 3)
- **Runtime Configuration**: Dynamic adjustment of behavior
### Phase 4: Documentation & Testing
#### 📚 **Comprehensive Documentation**
- **Enhanced README**: Complete rewrite with:
- Feature overview with emojis and sections
- Detailed parameter documentation
- Response format examples for both modes
- Configuration examples
- Troubleshooting guide
- Performance features documentation
