SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Generate and govern OpenAPI 3.1 specifications from code, design artifacts, and validation patterns to ensure consistent API contracts.

Core Features & Use Cases

  • Design-First: define API contracts before code and generate docs and SDKs.
  • Code-First: generate OpenAPI specs from existing codebases and annotations.
  • Validation & Portals: validate specs against code and publish docs to portals.

Quick Start

Start with your API design or source code and run the OpenAPI generator to produce a complete 3.1 spec.

FAQPage Schema
How do I generate an OpenAPI 3.1 specification from existing code?▼

Design-first OpenAPI generation defines API contracts before writing code, allowing you to generate documentation and SDKs upfront to ensure consistent implementation and validation patterns.

Can I validate my OpenAPI specs against my source code?▼

Yes, the Skill enforces OpenAPI 3.1 structure and provides templates to standardize comprehensive specifications, ensuring consistent API contracts across multiple design approaches without extra dependencies.

What's the best way to maintain consistent API documentation across different workflows?▼

The best way to maintain consistent API documentation is to generate and govern OpenAPI 3.1 specifications using standardized templates across design-first, code-first, and hybrid workflows.

Do I need a design-first approach to generate SDKs from an OpenAPI specification?▼

No, you do not need a design-first approach; SDK generation can be applied to OpenAPI 3.1 specifications derived from both design-first contracts and existing code-first annotations.
