auth-implementation-patterns

Quick Review

Excellent comprehensive authentication/authorization skill with strong practical coverage. The description accurately reflects the content, which includes production-ready code for JWT, OAuth2, sessions, RBAC, and security best practices. Structure is clear with well-organized sections and code examples. Task knowledge is deep with multiple patterns for each auth strategy, middleware implementations, and security hardening. Novelty is moderate-to-good: while auth patterns are well-documented online, having integrated, ready-to-use TypeScript implementations with refresh tokens, rate limiting, and RBAC in one skill saves significant integration time and tokens for a CLI agent. Minor improvement areas: could benefit from splitting large code blocks into referenced files for even cleaner structure, and adding diagrams for OAuth flows. The skill effectively reduces implementation complexity for a domain where security mistakes are costly.
