## 📊 Documentation Coverage
### API Endpoints Documented
-**Health Checks**: `/health`, `/api/health`
-**Agent Management**: `/api/agents` (GET, POST, GET/{id}, DELETE/{id})
- 🔄 **Tasks**: Partially documented (needs enhancement)
- 🔄 **Workflows**: Partially documented (needs enhancement)
- 🔄 **CLI Agents**: Partially documented (needs enhancement)
- 🔄 **Authentication**: Partially documented (needs enhancement)
### Response Models Coverage
-**Error Responses**: Standardized across all endpoints
-**Agent Responses**: Complete model coverage
-**Health Responses**: Simple and detailed variants
- 🔄 **Task Responses**: Basic models created, needs endpoint integration
- 🔄 **Workflow Responses**: Basic models created, needs endpoint integration
## 🎯 API Documentation Features
