Api Documenter

This does one thing well: it generates OpenAPI 3.0 specs for your REST and GraphQL APIs. You get proper YAML structure with paths, schemas, authentication, and error responses documented according to spec. It'll handle the boilerplate like parameter definitions, request bodies, and component references while you focus on the endpoint logic. The skill includes validation scripts and follows OpenAPI best practices like using $ref for shared schemas and documenting all response codes. Honestly most useful when you're building an API and need to maintain docs alongside code rather than bolting them on later. Auto-logs documentation activity through a session hook.
