SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes assets (resource) components.

What problem does it solve?

REST API design is error-prone and leads to inconsistent contracts, fragile client integrations, and costly migrations. This Skill provides a structured approach to design and review API contracts that are accurate, versioned, and production-ready.

Core Features & Use Cases

  • API contract design and review to ensure correct resource modeling, consistent HTTP semantics, stable error responses, and predictable behavior across services.
  • Pagination, filtering, sorting, and sparse fieldsets guidance to optimize payloads and performance.
  • Versioning strategy, deprecation planning, and backward-compatibility guidance to minimize breaking changes in public or partner APIs.
  • OpenAPI documentation alignment and automated checks to keep contracts in sync with implementation.

Quick Start

Review an existing API contract against the guidelines and begin drafting a versioned, well-documented REST API for a new resource.

FAQPage Schema
How do I design a REST API contract with correct resource modeling and HTTP semantics?

To design a REST API contract, analyze and validate resource modeling to enforce consistent HTTP semantics. This ensures predictable behavior, stable error responses, and robust contract definitions across services for production-ready endpoints.

What is the best way to handle REST API versioning and backward compatibility?

The best way to handle REST API versioning involves structured deprecation planning to minimize breaking changes. Applying versioning strategies ensures accurate, stable contracts that prevent fragile client integrations and costly migrations for public APIs.

How do I implement pagination and filtering to optimize REST API payloads?

To optimize REST API payloads, apply pagination, filtering, sorting, and sparse fieldsets strategies. This structured approach reduces payload size, improves performance, and ensures predictable behavior across API endpoints during data retrieval.

How do I structure REST API error responses to be RFC 7807 compliant?

Structuring RFC 7807-compliant REST API error responses involves enforcing standardized error models within your contract design. This ensures consistent, predictable error handling across services and maintains stable client integrations during failures.

Can I audit an existing REST API contract against standard design guidelines?

Yes, you can audit existing REST API contracts against design guidelines to validate resource modeling and HTTP semantics. This review identifies inconsistencies, ensures OpenAPI documentation alignment, and enforces robust contract definitions.
