Which frameworks does this skill support?

It supports a wide range of popular frameworks including Express, Fastify, Hono, Next.js, Flask, FastAPI, and Django REST.

How do I trigger the documentation generation?

You can use the /docs:api command or simply ask Claude to 'Generate API specification' in natural language within your terminal.

Can it extract complex data types?

Yes, it can extract definitions from TypeScript interfaces, Zod, Yup, Pydantic, and standard Python dataclasses to document your data models.

Does it require manual configuration for each project?

No, the skill uses framework detection patterns to automatically identify endpoints and types based on your project's structure.

Does it generate OpenAPI/Swagger files?

While it primarily generates structured Markdown specifications, it analyzes existing OpenAPI/Swagger files and can assist in drafting the content required for those formats.
