概要
This skill provides comprehensive guidance and production-grade patterns for building robust access control systems. It covers the full spectrum of modern security requirements—from stateless JWT implementations with refresh token rotation to stateful session management using Redis. Developers can leverage these patterns to integrate OAuth2 social logins, design scalable Role-Based Access Control (RBAC) hierarchies, and implement granular permission-based systems, ensuring that applications are secure, scalable, and compliant with best practices.
