📈 Quality Improvements

Before Implementation

• Basic FastAPI auto-generated docs
• Minimal endpoint descriptions
• No standardized error handling
• Inconsistent response formats
• Limited examples and use cases

After Implementation

• Professional, comprehensive API documentation
• Detailed endpoint descriptions with use cases
• Standardized error handling with error codes
• Type-safe response models with examples
• Interactive testing capabilities

🚀 Next Steps

High Priority

1. Complete Task API Documentation: Apply same standards to task endpoints
2. Workflow API Enhancement: Add comprehensive workflow documentation
3. CLI Agent Documentation: Document CLI agent management endpoints
4. Authentication Flow: Complete auth endpoint documentation

Medium Priority

1. API Usage Examples: Real-world integration examples
2. SDK Generation: Auto-generate client SDKs from OpenAPI
3. Performance Monitoring: Add performance metrics to documentation
4. Automated Testing: Test documentation examples automatically

Long Term

1. Multi-language Documentation: Support for multiple languages
2. Interactive Tutorials: Step-by-step API tutorials
3. Video Documentation: Video guides for complex workflows
4. Community Examples: User-contributed examples and guides

📋 Documentation Standards Established

1. Endpoint Documentation Structure

@router.get(
    "/endpoint",
    response_model=ResponseModel,
    status_code=status.HTTP_200_OK,
    summary="Brief endpoint description",
    description="Detailed multi-line description with use cases",
    responses={
        200: {"description": "Success description"},
        400: {"model": ErrorResponse, "description": "Error description"}
    }
)
