SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Design teams often struggle to create scalable REST and GraphQL APIs that are easy to document, maintain, and evolve. This skill provides a structured approach to resource modeling, operation design, versioning, and OpenAPI/GraphQL documentation to improve consistency and quality.

Core Features & Use Cases

  • Guides resource modeling, endpoint design, authentication strategies, and versioning plans for REST and GraphQL APIs.
  • Helps document APIs with OpenAPI specifications and GraphQL schemas to enable accurate communication with frontend and integration partners.
  • Use Case: design a new domain API or refactor an existing one to improve consistency and maintainability.

Quick Start

Draft a complete API design for a sample domain, including resources, endpoints, auth, and versioning to validate the approach.

FAQPage Schema
How do I design robust REST and GraphQL APIs with proper versioning and error handling?

This skill provides structured API design guidance for resource modeling, authentication, versioning, and error handling to build scalable REST and GraphQL APIs that are easy to document and maintain.

What's the best way to document OpenAPI specifications and GraphQL schemas?

The best way to document OpenAPI specifications and GraphQL schemas is to apply best-practice design guidance during resource modeling. This ensures accurate communication with frontend and integration partners by maintaining consistent API naming and documentation.

How do I refactor existing endpoints to improve consistency and maintainability?

Refactoring existing endpoints requires applying structured operation design, versioning plans, and authentication strategies. This improves consistency and maintainability by aligning your REST and GraphQL endpoints with established API best practices.

Can I use this approach for both REST and GraphQL API authentication strategies?

Yes, this approach applies to both REST and GraphQL ecosystems. It provides guidance on designing authentication strategies, resource modeling, and pagination across both architectures to improve overall API consistency and quality.

When do I need a structured approach for API resource modeling and naming?

You need a structured approach for API resource modeling and naming when creating a new domain API or refactoring an existing one. It helps satisfy requirements for versioning, error handling, pagination, and OpenAPI documentation to prevent scalability issues.
