## File Organization Principles
### 1. Separation of Concerns
**Code vs. Documentation**: Clear separation between implementation and documentation
- Source code in `src/` with modular organization
- Documentation in `docs/` and `approach/`
- Data files in `data/`
- Database files in `db/`
- Tests in `tests/`
- Scripts in `scripts/`
### 2. Modular Design
**Component Isolation**: Each component has a specific responsibility
- Client handles user interaction and communication
- Server manages MCP protocol and tool coordination
- Tools provide specific functionality (calculator, weather, knowledge base)
- Rate limiter ensures API compliance
- Utilities provide shared functionality
### 3. Scalability Considerations
**Extensible Structure**: Easy to add new components
- New tools can be added to `src/tools/`
- Additional utilities can be added to `src/utils/`
- New tests can be added to `tests/`
- Additional documentation can be added to appropriate folders
- Additional data sources can be added to `data/`
### 4. Maintainability Focus
**Clear Organization**: Easy to find and modify components
- Logical grouping of related files
- Consistent naming conventions
- Comprehensive documentation
- Clear dependency relationships
## Development Workflow
### 1. Adding New Features
**Source Code**: Add new modules to appropriate `src/` subdirectories
**Documentation**: Update relevant files in `docs/` or `approach/`
**Testing**: Add tests to `tests/`
**Data**: Add configuration to `data/` if needed
**Scripts**: Add utility scripts to `scripts/` if needed
### 2. Modifying Existing Features
**Locate**: Find the relevant component in the appropriate directory
**Update**: Modify the implementation
**Test**: Run relevant tests in `tests/`
**Document**: Update documentation if needed
### 3. Rate Limiting Changes
**Implementation**: Modify `src/utils/persistent_rate_limiter.py`
**Configuration**: Update limits or behavior
**Testing**: Use `tests/` for validation
**Monitoring**: Use `scripts/monitor_rate_limits.py` for monitoring
## Configuration Management
### 1. Environment Variables
**Location**: `.env` file in project root
**Contents**: API keys, configuration settings
**Security**: Never committed to version control
### 2. Knowledge Base
**Location**: `data/knowledge_base.json` and `data/kb.json`
**Format**: Structured Q&A pairs
**Updates**: Version controlled, easy to modify
### 3. Rate Limiting Configuration
**Location**: `src/utils/persistent_rate_limiter.py`
**Settings**: Limits, safety margins, token estimation
**Database**: `db/rate_limit_tracker.db`
**Customization**: Easy to modify for different requirements
## Deployment Considerations
### 1. File Organization
**Production**: All files in their designated locations
**Dependencies**: Clear separation of requirements
**Configuration**: Environment-specific settings
### 2. Security
**API Keys**: Stored in environment variables
**Data**: Knowledge base can be customized per environment
**Access**: Proper file permissions and access controls
### 3. Monitoring
**Logs**: Application logs for debugging
**Metrics**: Rate limiting status and performance
**Health Checks**: System availability monitoring
