}
```

## 🎯 Usage Examples

### Basic Analysis
```bash
gemini-flow analyze
```

```

## 🏗️ Architecture Integration

### Backend API Patterns Applied

1. **Command Pattern**: Clean separation of command logic and execution
2. **Strategy Pattern**: Different analysis strategies for various depths
3. **Factory Pattern**: Dynamic report generator creation based on output format
4. **Observer Pattern**: Progress reporting through spinners and logging
5. **Template Method**: Consistent analysis workflow with customizable steps

### Error Handling & Resilience

- **Graceful degradation** with emergency fallback mode
- **Comprehensive error reporting** with actionable messages
- **Validation** at multiple levels (options, repository, file access)
- **Resource cleanup** and safe file operations

### Performance Optimizations

- **Parallel file processing** where possible
- **Efficient pattern matching** using optimized regex
- **Memory-conscious** large file handling
- **Progress indication** for long-running operations

## 📈 Coordination with System Architecture

The analyze command integrates seamlessly with the existing Gemini Flow architecture:

1. **CLI Framework**: Uses Commander.js consistent with other commands
2. **Logging System**: Integrated with existing Logger infrastructure
3. **Configuration Management**: Leverages ConfigManager for settings
4. **Error Handling**: Follows established error patterns
5. **Output Formatting**: Consistent with CLI styling using chalk

## 🔧 Development Notes

### Coordination Hooks Used
- ✅ `pre-task` - Initialized coordination for analyze implementation
- ✅ `post-edit` - Stored architecture analysis in swarm memory
- ✅ `post-task` - Completed task coordination with performance analysis
- ✅ `notify` - Final coordination notification of completion

### Memory Coordination
All major implementation decisions and patterns stored in swarm memory under:
- `swarm/backend-dev/architecture-analysis`
- Task completion tracked with performance metrics
