Parse the source with Python's ast module to extract route decorators, function signatures, and docstrings, then map them into an OpenAPI specification. The extracted endpoints can be rendered with Swagger UI or Redoc for interactive documentation.

Extract HTTP methods, paths, parameters, and Pydantic schemas from the codebase, then populate an OpenAPI 3.0 YAML template with components, security schemes, and response definitions. Validate the output with tools like Redocly before publishing.

Yes, a GitHub Actions workflow can regenerate OpenAPI specs and Sphinx docs on every push to main, then deploy the built site to GitHub Pages. This keeps published documentation synchronized with code changes automatically.

Walk the AST of each source file and compare functions and classes that have docstrings against the total count. The result is a coverage percentage plus a list of undocumented items with file and line references.

Avoid it when there is no codebase or source of truth to extract from, or when you only need a one-off explanation. Generated docs also require review to avoid exposing secrets, internal URLs, or sensitive configuration details.
