# 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 `resources/implementation-playbook.md`. ## Resources - `resources/implementation-playbook.md` for detailed patterns and examples. ## Limitations - Use this skill only when the task clearly matches the scope described above. - Do not treat the output as a substitute for environment-specific validation, testing, or expert review. - Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria

Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
