- **Reliability**: Success rate and consistency
- **Memory Usage**: Peak memory and resource efficiency
- **Concurrent Load**: Multi-request handling

**Performance Targets**:
- 90%+ accuracy on test questions
- <30 seconds average response time
- >80% success rate
- <500MB peak memory usage
- Consistent performance under load

## Test Implementation Strategy

### TDD Methodology Applied

1. **Red Phase**: Created failing tests first
   - Defined expected behaviors for each question type
   - Established performance thresholds
   - Created validation criteria

2. **Green Phase**: Validated existing implementation
   - Confirmed agent integration with Enhanced Response Processor
   - Verified tool functionality across all 11 tools
   - Validated multimodal capabilities

3. **Refactor Phase**: Optimized test structure
   - Modularized test categories
   - Improved error handling
   - Enhanced performance measurement
