SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables teams to design consistent REST APIs with clear resource modeling, robust pagination/filtering, a standardized error model, and versioning guidelines, while producing an OpenAPI draft and implementation contracts (controllers/service interfaces) for backend work.

Core Features & Use Cases

  • Resource modeling (nouns, hierarchies, relationships) and explicit endpoint semantics (GET/POST/PUT/PATCH/DELETE) with idempotency guidance.
  • Pagination, filtering, and sorting patterns and response shapes, plus stable error handling using RFC 9457 Problem Details.
  • Versioning strategy and backward-compatible changes, along with producing an OpenAPI draft and contract definitions for controllers and services.

Quick Start

Design a complete REST API plan for a new endpoint, including resources, endpoints, pagination, errors, and an OpenAPI draft.

FAQPage Schema
How do I design a REST API with OpenAPI contracts in Java?▼

Design REST APIs using contract-first principles by defining resource models, endpoint semantics, and pagination patterns, then generating an OpenAPI draft alongside controller and service interface contracts for framework-agnostic Java backends.

What's the best way to handle REST API pagination and filtering?▼

Standardize REST API pagination and filtering by applying consistent response shapes and sorting patterns. This approach enforces clear resource modeling rules to ensure stable, predictable list responses across all endpoints.

How does RFC 9457 Problem Details work for REST API error handling?▼

RFC 9457 Problem Details provides a standardized error model for REST APIs, returning consistent error responses. This approach replaces ad-hoc error formats with a structured payload that clients can reliably parse for failure details.

When do I need contract-first API design for backend development?▼

Contract-first API design is needed when adding new endpoints or redesigning existing APIs across Java backends. It ensures teams agree on OpenAPI specifications and interface contracts before implementation, preventing integration mismatches.

Can I use this REST API design approach with any Java framework?▼

Yes, this approach targets framework-agnostic Java backends, producing OpenAPI drafts and controller or service interface contracts that can be adapted to various Java frameworks without hard dependencies.
