Openapi Spec Generation
If you're building REST APIs and need to generate or maintain OpenAPI 3.1 specs, this handles both the design-first and code-first workflows. It covers the full cycle: writing specs from scratch, extracting them from existing implementations, validating your API against the contract, and even prepping for SDK generation. The implementation playbook has concrete patterns you can follow. It's community sourced, so quality may vary, but the scope is clear and focused. Most useful when you're setting up new API docs or trying to enforce contract compliance across teams. Not a replacement for actually testing your API, just a solid starting point for the spec work.

OpenAPI Spec Generation
Comprehensive patterns for creating, maintaining, and validating OpenAPI 3.1 specifications for RESTful APIs.
Use this skill when
- 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
Do not use this skill when
- The task is unrelated to openapi spec generation
- You need a different domain or tool outside this scope
Instructions
- Clarify goals, constraints, and required inputs.
- Apply relevant best practices and validate outcomes.
- Provide actionable steps and verification.
- If detailed examples are required, open
