概要
This skill equips Claude with the expertise to design and implement robust security architectures for modern web applications and APIs. It provides detailed implementation patterns for token-based authentication (JWT) with refresh token flows, stateful session management using Redis, and social logins via OAuth2/Passport.js. Beyond simple login logic, it guides the creation of sophisticated authorization models, including Role-Based Access Control (RBAC) and permission-based systems, ensuring that your application's security is both scalable and compliant with modern best practices.
