For MCPOverflow integration, the workflow would be:

1. User provides API specification (OpenAPI/GraphQL/Postman)
   ↓
2. OpenHands Agent analyzes the spec
   - Action: READ (read API spec file)
   - Action: BROWSE (fetch additional documentation if needed)
   ↓
3. OpenHands generates MCP connector code
   - Action: WRITE (create connector file)
   - Action: EDIT (refine code based on requirements)
   ↓
4. OpenHands generates tests
   - Action: WRITE (create test files)
   ↓
5. OpenHands validates the code
   - Action: RUN (execute tests)
   - Action: EDIT (fix any issues)
   ↓
6. Return generated code to MCPOverflow

Status: DEMO MODE (No API key provided)

✓ OpenHands SDK is installed
✓ Core modules are functional
✓ Action types are available for MCP integration
✓ Workflow is documented

To run a real code generation test:
1. Set ANTHROPIC_API_KEY or OPENAI_API_KEY
2. Run: poetry run python test_openhands_codegen.py
3. OpenHands will generate actual MCP connector code

Next Steps for MCPOverflow Integration:
1. Create OpenHands adapter service (Node.js/TypeScript)
2. Define task templates for MCP connector generation
3. Integrate with MCPOverflow API backend
4. Add result parsing and validation
5. Test with real API specifications (Stripe, GitHub, etc.)
