Quick Review

Excellent comprehensive skill for API security implementation. The description clearly conveys the skill's scope (authentication, authorization, input validation, rate limiting, vulnerability protection), enabling accurate invocation. Task knowledge is outstanding with detailed, production-ready code examples covering JWT authentication, SQL injection prevention, rate limiting with Redis, DDoS protection, and OWASP Top 10 considerations. The structure is logical and well-organized with clear sections, step-by-step guides, practical examples, best practices, common pitfalls, and a security checklist. The skill demonstrates high novelty by providing specialized security patterns that would require significant research and token usage for a CLI agent to assemble correctly - particularly the integration of multiple security layers (JWT + refresh tokens, tiered rate limiting, Zod validation, Helmet configuration). The comprehensive coverage of authentication flows, vulnerability prevention patterns, and security testing approaches makes this a valuable, token-efficient resource for implementing robust API security.
