Analyze an OpenAPI specification file for quality issues across four dimensions: schema validity, completeness, REST design best practices, and security. Use this skill whenever a user uploads or provides an OpenAPI spec (JSON format) and asks for a review, audit, quality check, lint, or feedback — or whenever they ask things like "check my API spec", "what's wrong with this OpenAPI file", "review my swagger", or "is this spec production-ready?". Always use this skill for OpenAPI/Swagger quality tasks — do not attempt to review specs manually without it.
