Summary
Covers authentication setup for Next.js apps on Vercel, focusing on three providers: Clerk (recommended for its native Marketplace integration with auto-provisioned env vars), Descope, and Auth0. The skill walks you through middleware patterns, route protection, and the typical sign-in/sign-up flow setup. It auto-triggers when you're working in middleware.ts, installing auth packages, or touching auth-related files. Includes validators that nudge you away from hand-rolled OAuth implementations toward managed providers. The Clerk section is the most complete here, with Core 3 patterns and frontend API proxy config. If you're adding login to a Next.js app and want to skip the usual auth headaches, this gets you to working code fast.
