Openapi Expert

What it does

This skill provides expert guidance related to the OpenAPI Specification (OAS), formerly known as Swagger. It allows AI agents to understand and work with API descriptions formatted in YAML or JSON, enabling tasks like automatic documentation generation, client/server code generation, API validation, and testing. The skill supports OAS versions 3.1 (the latest) and 3.0.

When to use it

• When needing to understand the structure and functionality of a RESTful API described using OpenAPI.
• To generate documentation for an API based on its OpenAPI definition.
• For validating an OpenAPI document against the specification.
• To assist in generating code (client or server-side) from an OpenAPI definition.

Key capabilities

• Understanding and interpreting OpenAPI Specification documents (versions 3.0 & 3.1).
• Knowledge of core OAS components: Paths, Operations, Parameters, Request/Response bodies, Schemas, Security schemes, and Components.
• Ability to analyze API endpoints, HTTP methods, request parameters, and response structures defined in the OpenAPI document.

Example prompts

• "Explain the purpose of the /posts endpoint in this OpenAPI definition."
• "Generate documentation for the createPost operation based on this OpenAPI specification."
• "Validate this OpenAPI file and identify any errors."

Tips & gotchas

• The skill requires a valid OpenAPI Specification document (YAML or JSON) as input.
• While it supports both OAS 3.0 and 3.1, the behavior might vary slightly depending on the version used.
