api-surface

Maps the entire API surface of a codebase -- route definitions, middleware chains, auth requirements, request/response types, deprecated endpoints, orphaned endpoints, and cross-endpoint inconsistencies. USE THIS SKILL WHEN: - You need a complete inventory of all API endpoints in a project - Someone asks "what endpoints do we have?" or "what does our API look like?" - You are onboarding to a new backend codebase and need to understand its API - You need to find orphaned, undocumented, or deprecated endpoints - Someone asks about API inconsistencies (different response shapes, auth gaps) - You are preparing for an API review, documentation sprint, or versioning migration - You need to understand endpoint dependencies before refactoring - A project has no OpenAPI spec and you need to generate one from code - You suspect there are endpoints without authentication or rate limiting TRIGGER PHRASES: "API surface", "list all endpoints", "API inventory", "endpoint map", "orphaned endpoints", "
