SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides governance for API contracts to ensure backend and frontend teams align on unified response shapes, pagination, and error codes, reducing integration friction.

Core Features & Use Cases

  • API contract governance: standardizes response structures, pagination fields, and error codes across services.
  • Frontend-backend alignment: validates that frontend API consumption matches backend definitions and data contracts.
  • Smoke testing & validation: supports checks against governance rules and validation guides during development and CI.

Quick Start

Apply governance to a REST endpoint to align backend and frontend definitions with the unified response, pagination, and error-code rules.

FAQPage Schema
What is API contract governance for standardizing REST response shapes?▼

API contract governance standardizes REST response shapes, pagination fields, and error codes across services. It enforces consistent backend and frontend data contracts to reduce integration friction when adding or modifying interfaces.

How do I validate frontend API consumption against backend REST definitions?▼

Validate frontend API consumption against backend definitions by applying governance rules that check data contracts. This ensures frontend data expectations match backend controller responses and unified response structures during development.

How do I enforce consistent error codes and pagination fields across backend services?▼

Enforce consistent error codes and pagination fields by applying API contract governance rules to backend REST interfaces. This standardizes controller responses and aligns backend service outputs with frontend data contract expectations.

Can I run local smoke testing for API contract validation without exposing credentials?▼

Yes, you can run local smoke testing for API contract validation without exposing credentials. Governance checks validate controller responses against rules during development and CI without requiring sensitive authentication data.

When do I need to apply API contract governance during frontend and backend development?▼

Apply API contract governance when adding or modifying backend REST interfaces or frontend API consumption. It is needed to validate controller responses and frontend data contracts to ensure unified response structures and reduce integration friction.
