描述
Publish or refresh developer-facing API documentation for REST, GraphQL, webhook, SDK, and developer-portal surfaces: reference docs, quickstarts, task guides, auth/setup notes for API consumers, truthful example requests, error/retry/limit guidance, and migration updates. Use when the contract already exists and the main job is helping integrators succeed with the API, not designing resources or versioning strategy. Triggers on: API docs, developer portal, OpenAPI reference, SDK docs, webhook docs, quickstart, integration guide, endpoint reference, pagination docs, rate-limit docs, migration note, and partner API guide. Route contract design to `api-design`, internal specs/runbooks to `technical-writing`, end-user UI help to `user-guide-writing`, auth implementation to `authentication-setup`, and release-note hygiene to `changelog-maintenance`.
