Iron Law: Never generate an OpenAPI spec without running it through a validator; always produce machine-parseable YAML/JSON, not prose descriptions.

OpenAPI Spec Generation

Generate, validate, and maintain OpenAPI 3.1 specifications for RESTful APIs. Supports design-first, code-first, and hybrid approaches across Java/Spring, Python/FastAPI, and TypeScript stacks.

When to Use

• Creating API documentation from scratch
• Generating OpenAPI specs from existing code
• Designing API contracts (design-first approach)
• Validating API implementations against specs
• Generating client SDKs from specs
• Setting up API documentation portals
