Openapi Spec Generation

The openapi-spec-generation skill allows AI agents to automatically create OpenAPI specification files based on provided API descriptions or code snippets. It streamlines the process of defining RESTful interfaces, ensuring consistent documentation and contract validation for backend services.

When to use it

• Rapidly prototype new API endpoints without manually writing YAML or JSON definitions.
• Generate standard documentation from existing function signatures or route handlers.
• Validate that AI-generated code adheres to a specific OpenAPI schema structure.
• Accelerate frontend-backend integration by providing immediate interface contracts.

Key capabilities

• Converts natural language API descriptions into structured OpenAPI specs.
• Parses source code snippets to extract endpoint details and parameters.
• Outputs standard OpenAPI format (YAML or JSON) ready for import into tools like Swagger UI.

Example prompts

• "Generate an OpenAPI specification for a user authentication service with login, logout, and profile update endpoints."
• "Create an OpenAPI spec based on this Python Flask route handler code snippet."
• "Define the API contract for a weather data retrieval service that accepts latitude and longitude parameters."

Tips & gotchas

Ensure you provide clear context about the expected request/response formats to avoid generic or inaccurate schema generation. The output may require manual refinement if complex business logic isn't explicitly described in your input.
