Does this skill support the Next.js App Router?

Yes, it includes specific patterns for App Router middleware and Route Handlers for seamless modern integration.

How does it handle backend verification with Convex?

The skill provides patterns for configuring Clerk JWT templates that allow Convex to verify user identity using ctx.auth.getUserIdentity().

How are public and private routes managed?

It utilizes the clerkMiddleware function combined with createRouteMatcher to define public access for routes like sign-in and webhooks while protecting everything else.

Is webhook verification included in the patterns?

Absolutely. It provides a robust implementation using the Svix library to verify headers and signatures for secure user synchronization.
