SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes the manual burden of drafting, updating, and validating OpenAPI specifications so API contracts stay accurate as code evolves.

Core Features & Use Cases

  • Specification Authoring: Create OpenAPI 3.1 documents from scratch or from existing implementation details.
  • Contract Maintenance: Keep paths, schemas, parameters, responses, and security definitions aligned with the API surface.
  • Validation and Tooling: Apply linting, examples, and generator-ready patterns for docs portals and SDK creation.
  • Use Case: A backend team can turn a set of REST endpoints into a consistent API spec, validate it, and generate client libraries for downstream consumers.

Quick Start

Use the openapi-spec-generation skill to create a complete OpenAPI 3.1 specification for a REST API, including schemas, responses, security, and validation guidance.

FAQPage Schema
How do I generate an OpenAPI 3.1 specification from existing REST API endpoints?▼

You can generate an OpenAPI 3.1 specification from existing REST endpoints using a code-first workflow that extracts paths, schemas, and parameters to produce a compliant API contract document.

What's the best way to maintain an OpenAPI specification as my REST API evolves?▼

Maintain an OpenAPI specification by using contract maintenance workflows that keep paths, schemas, responses, and security definitions aligned with your evolving API surface.

Can I use my OpenAPI specification for SDK generation and documentation portals?▼

Yes, OpenAPI specifications can be formatted with generator-ready patterns, linting, and examples to produce client libraries for SDK generation and docs portals.

Do I need reusable schemas and security schemes for valid OpenAPI 3.1 compliance?▼

Yes, OpenAPI 3.1 compliance requires defining reusable schemas, parameters, responses, security schemes, and examples that satisfy linting patterns.

What is the design-first approach to building REST API contracts?▼

The design-first approach to REST API contracts involves authoring a complete OpenAPI 3.1 specification from scratch before implementation, covering schemas, security, and validation guidance.

Why does my generated SDK fail contract validation against my REST API?▼

SDK contract validation fails when your OpenAPI specification falls out of sync with the API surface, requiring contract maintenance to realign schemas, parameters, and responses.
