# Clerk Authentication & Drop-in User Management Components

Configures Clerk in Next.js: wrapping with <ClerkProvider>, drop-in components (<SignIn />, <SignUp />, <UserButton />, <OrganizationSwitcher />), protecting routes with clerkMiddleware, and webhook synchronization.

## When to Invoke
Invoke this skill whenever you need to:
- setup clerk nextjs
- protect route clerkmiddleware
- clerk userbutton component

## Execution SOP & Rules
1. Wrap layout: <ClerkProvider><html ...><body>{children}</body></html></ClerkProvider>.
2. Protect routes in middleware.ts using clerkMiddleware((auth, req) => { if (isProtectedRoute(req)) auth().protect(); }).
3. Add user avatar menu: <UserButton afterSignOutUrl='/' />.
4. Access current user in Server Components: const { userId } = await auth(); if (!userId) redirect('/sign-in').

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
