API documentation has a synchronization problem. Docs are written at launch, code changes weekly, and the drift compounds until the docs are more harmful than helpful — a developer trusts the documented behavior and ships a bug because the actual behavior diverged six months ago.
AI coding tools accelerate this problem. When 40–60% of API surface area is generated by AI tools, the author of those endpoints often doesn't have deep enough understanding to write accurate documentation. The AI generated the code; no human fully reviewed it; the docs get written from the code's apparent behavior rather than its intended contract.
GitIntel's documentation generator reads your actual route handlers, type definitions, and request/response patterns to produce OpenAPI 3.1 specifications. It's not inferring from comments — it's reading the code. For AI-generated endpoints, it adds an attribution note so documentation consumers know which parts had the highest likelihood of undocumented edge cases.
Run `gitintel docs --format openapi` to generate a complete spec. Supports Express, Fastify, Next.js App Router API routes, FastAPI, and Go's standard http library.
