Ultimate API Design Review: Enhance Your REST & GraphQL Contracts

Ultimate API Design Review: Enhance Your REST & GraphQL Contracts

This AI agent skill provides a structured review of API contracts for REST and GraphQL, focusing on resource naming, HTTP semantics, status codes, error shape, pagination, versioning, idempotency, and backward compatibility. It aids developers in producing concrete revisions rather than abstract advice during the design or modification of API endpoints.

What this skill does

• First, it establishes the existing API contract by analyzing current routes and resolvers, including path, verbs, request/response shapes, and error handling.
• It identifies existing conventions such as error envelope shape, pagination style, naming case, plural vs. singular resources, authentication mechanism, and versioning scheme.
• It evaluates new or changed API surfaces against the existing conventions, ensuring consistency with current API output unless there is a stated reason for divergence.
• The skill produces a checklist-driven review for each modification or addition, grounded in the project’s prevailing standards.

Who it is for

• API Developers seeking to maintain or enhance the consistency and reliability of their contract interfaces.
• Development teams focusing on REST or GraphQL API projects, looking for robust review processes.
• Professionals utilizing AI coding agents like Claude Code, Cursor, and Codex to manage their workflow.

Use cases

• Reviewing API contracts during the design phase to avoid potential consumer-side inconsistencies.
• Assessing a pull request that introduces or alters API routes to ensure alignment with existing standards.
• Facilitating team discussions around API changes with evidence-based evaluations of current conventions.

Technical details

• Integrates seamlessly with aiapplication, agentic-tools, and api-design-review modules.
• Compatible with developers using AI tools like Claude Code, Cursor, and Codex for enhanced API management.
