SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires redocly, prism, schemathesis, oasdiff, openapi-generator-cli, and includes scripts (resource) and references (resource) components.

What problem does it solve?

OpenAPI contracts are the machine-readable contracts that drive automation for API design, validation, mocking, testing, and code generation. They serve as a single source of truth that enables AI agents and engineers to reason about endpoints, parameters, and schemas without ambiguity.

Core Features & Use Cases

  • Design robust APIs with stable operation IDs, reusable components, and clear schemas.
  • Validate and bundle multi-file specs using Redocly CLI.
  • Generate type-safe clients, servers, and models with OpenAPI Generator.
  • Mock APIs locally with Prism for frontend and integration testing.
  • Exercise live services with contract tests using Schemathesis.
  • Diff contracts to surface breaking changes with oasdiff.

Quick Start

Validate your OpenAPI document, bundle it if needed, and then perform generation or mocking with the provided scripts.

Frequently Asked Questions about openapi

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate and bundle a multi-file OpenAPI spec?▼

To validate and bundle OpenAPI specs, you can use Redocly CLI to lint multi-file API descriptions and resolve external references into a single bundled document for CI or local workflows.

What is the best way to mock an OpenAPI API for frontend integration testing?▼

The best way to mock OpenAPI APIs for frontend testing is using Prism, which generates local mock servers directly from your API description to simulate endpoint responses during integration.

Can I generate type-safe clients and servers from an OpenAPI contract?▼

Yes, you can generate type-safe clients, servers, and models from OpenAPI contracts using OpenAPI Generator, enabling automated code generation directly from your machine-readable API schemas.

How do I surface breaking changes between OpenAPI contract versions?▼

To surface breaking changes between OpenAPI contract versions, use oasdiff to diff API descriptions and automatically identify modifications that could break existing client integrations.

How does contract testing work with live services using OpenAPI?▼

Contract testing with OpenAPI works by using Schemathesis to exercise live services against your API description, verifying that endpoint implementations conform to the defined schemas and parameters.

Do I need an OpenAPI contract to run automated API testing in CI?▼

You need an OpenAPI contract to run automated API testing in CI because it serves as a machine-readable single source of truth, enabling validation, mocking, and contract testing without ambiguity.
