Implements secure route guards and authorization patterns using Clerk middleware for Next.js applications.
This skill provides comprehensive guidance and implementation patterns for securing Next.js applications at the edge using Clerk middleware. It enables Claude to intelligently configure route matchers, define public versus protected boundaries, and implement advanced security features like Role-Based Access Control (RBAC) and organization-level isolation. By following a 'deny-by-default' security philosophy, this skill ensures that sensitive data and API endpoints remain protected while maintaining a seamless user authentication flow.
