api-patterns

Quick Review

Excellent API design skill with clear structure and comprehensive coverage. The content map efficiently guides selective reading across 10 specialized files covering REST, GraphQL, tRPC, versioning, auth, rate-limiting, and security. The decision checklist and anti-patterns provide actionable guidance. Strong emphasis on context-driven design ('THINK, not copy') adds value. The skill meaningfully reduces token costs by organizing deep API knowledge that would otherwise require extensive prompting. Minor limitation: while novel for comprehensive API pattern comparison, some individual patterns (REST basics) are well-known, slightly reducing overall novelty score.
