概要
This skill empowers Claude to architect and implement robust security layers for modern applications by providing structured guidance on identity and access management. It covers the full spectrum of security needs, from stateless JWT authentication with refresh token rotation to stateful session management using Redis. It also provides implementation patterns for third-party social logins via OAuth2 and flexible authorization models, including Role-Based Access Control (RBAC) and granular permission systems. Whether you are securing a REST API or migrating an existing authentication flow, this skill ensures best practices are followed for scalability and defense-in-depth.
