Api And Interface Design

Document decisions and architecture rationale �� capture why, not just what

Plan tests for an API endpoint or service — functional, negative, and contract. Use when asked to test an API, write API test cases, plan REST/GraphQL endpoi...

Review an API's contract as a promise to consumers — detects breaking changes by diffing the before/after surface (removed/renamed fields, type changes, tightened requiredness, status-code changes), and judges design by the repo's OWN precedent (error envelope, naming, pagination, auth placement) with every consistency finding citing the in-repo convention being violated. Covers versioning, idempotency on retryable writes, pagination on collections, and status-code semantics. Use this skill whenever the user says "review this API", "review the endpoint", "API design review", "is this a breaking change", "check backward compatibility", "review the contract", "review this OpenAPI/swagger spec", or "/api-contract-review" — even if they don't name the skill. Distinct from code-review (implementation quality); this reviews the SURFACE consumers depend on.

Write clear, developer-facing API documentation. Use when asked to document an API endpoint, write API reference docs, create a developer guide, or turn a ra...

Review an API change for compatibility, validation, auth, error shape, idempotency, and observability, and classify it as additive, behavior-changing, or bre...
