Summary
Handles authentication setup for Next.js apps on Vercel with a focus on three providers: Clerk (which gets native Marketplace integration with auto-provisioned env vars), Descope, and Auth0. Triggers when you're working in middleware.ts, auth config files, or installing auth packages. Covers the standard flow of protecting routes, setting up sign-in pages, and accessing user sessions in both server and client components. The skill includes migration guidance if it spots legacy next-auth v4 patterns or manual JWT handling with jsonwebtoken, nudging you toward managed solutions. Honestly most useful for the Clerk-specific stuff since that's where the Vercel integration really pays off.
