## Data Flow Architecture

### Command Processing Flow
```
User Input → main.py → cli/parser.py → cli/commands.py → tools/* → models/* → Response
```

### LLM Integration Flow
```
Tool Request → model_orchestration.py → model_manager.py → api_client.py → LLM API → Response
```

### File Operation Flow
```
Tool → file_tools.py → File System → Response
```

### Security Scanning Flow
```
security_scan() → SecurityScanner → [bandit, safety, patterns] → vulnerability_report()
```

## Feature Implementation Status

## Key Technical Patterns

### Design Patterns Used
- **Factory Pattern**: Model selection and tool instantiation
- **Command Pattern**: Task representation and execution
- **Observer Pattern**: Callback system for task completion
- **Plugin Architecture**: Modular tool system

### Integration Patterns
- **API Gateway Pattern**: Unified LLM access through api_client.py
- **Circuit Breaker Pattern**: Error handling and fallback mechanisms
- **Caching Pattern**: Results caching for cost optimization
- **Queue Pattern**: Task queuing in model orchestration

### Security Patterns
- **Input Validation**: All user inputs validated and sanitized
- **Principle of Least Privilege**: Permission prompts for system commands
- **Defense in Depth**: Multiple security scanning layers
- **Secure by Default**: Safe configuration defaults

## Performance Characteristics

### Concurrency Model
- ThreadPoolExecutor for parallel task processing
- Configurable thread limits via CLOVER_THREADS
- Async-compatible architecture for future enhancements

### Memory Management
- Streaming file processing for large projects
- Result caching with configurable limits
- Garbage collection friendly object lifecycle

### Network Optimization
- Request batching for multiple LLM calls
- Connection pooling for API clients
- Retry mechanisms with exponential backoff

## Extension Points

### Adding New Tools
1. Create new module in tools/
2. Import required dependencies (file_tools, api_client, etc.)
3. Follow established patterns for error handling
4. Register with CLI commands in cli/commands.py

### Adding New Models
1. Update model profiles in model_orchestration.py
2. Add API client support if needed
3. Configure capabilities and cost parameters

### Adding New Languages
1. Update dependency_tools.py with package manager support
2. Add security patterns to security_tools.py
3. Update test generation templates in test_generation.py

## Quality Metrics
