It enforces rules on the OpenAPI spec itself in CI — missing descriptions, naming, examples — so a poor spec fails the build rather than becoming poor documentation.

Yes, CLion natively integrates AI with support for Claude, GPT, Gemini, and Grok models. Users can apply JetBrains AI credits or bring their own API keys to avoid vendor lock-in.

Source
Redocly: Do I need OpenAPI to use it?
