Generate Swagger Docs

What it does

This skill automatically generates Swagger documentation from existing codebases or API definitions. It creates interactive, standardized OpenAPI specifications that allow developers to visualize endpoints, request/response schemas, and authentication methods without manual writing.

When to use it

• You need to document a new API quickly before releasing it to clients.
• Your team wants an interactive playground to test API calls directly in the browser.
• You are refactoring code and need to ensure API contracts remain consistent with implementation details.
• Stakeholders require non-technical documentation to understand system capabilities without reading source code.

Key capabilities

• Parses codebases or OpenAPI definitions to extract endpoint logic.
• Generates interactive Swagger UI for immediate testing of requests and responses.
• Outputs standard OpenAPI/Swagger format compatible with most API clients.
• Captures request parameters, response models, and authentication requirements automatically.

Example prompts

• "Generate a complete Swagger document from my Express.js server code located in the api/ folder."
• "Create an interactive Swagger UI for this Python FastAPI application so I can test endpoints locally."
• "Extract API documentation from my Node.js project and output it as a downloadable OpenAPI JSON file."

Tips & gotchas

Ensure your codebase includes clear function comments or docstrings, as the generator relies on these to infer accurate parameter descriptions. Complex authentication flows may require manual verification after generation to ensure security headers are correctly documented.
