API Documentation Skill

Generate clear, complete, professional API documentation from any form of API input.

Supported Input Formats

Accept any of the following as input:

• OpenAPI / Swagger (YAML or JSON, v2 or v3)
• Endpoint list (plain text, e.g. GET /users/:id)
• Route definitions (Express, FastAPI, Django, Rails, etc.)
• Controller / handler code (infer from function signatures and decorators)
• Informal descriptions ("I have an endpoint that creates a user and takes name + email")
• Postman collections (JSON)
• gRPC proto files (document as method-based API)
• GraphQL schema (document as query/mutation reference)

If the input is ambiguous, make reasonable inferences and note assumptions clearly.
