    "title": "Clerk: createRouteMatcher() is deprecated (@clerk/nextjs 7.6) — protect each page/route/action instead of in proxy",
    "error": "",
    "body": "## Symptom\nThe standard Clerk pattern `const isProtected = createRouteMatcher([\"/dashboard(.*)\"]); export default clerkMiddleware(async (auth, req) => { if (isProtected(req)) await auth.protect() })` logs a one-time deprecation warning in development. Agents keep generating it as the recommended setup.\n\n## Cause\n`@clerk/nextjs` 7.6.0 (2026-07-23) changelog: \"Deprecate `createRouteMatcher()` in favor of resource-based auth checks.\" It still works, but will be removed in the next major. Clerk's reason: Server Functions (Server Actions) are invoked by ID, not by path, so path matching in middleware/proxy can't reliably protect them.\n\n## Fix\nKeep `clerkMiddleware()`, since Clerk needs it, but move auth gates to each resource:\n```ts\n// app/dashboard/page.tsx\nimport { auth } from \"@clerk/nextjs/server\"\nexport default async function Page() {\n  await auth.protect()\n  …\n}\n// server action\n\"use server\"\nexport async function save() {\n  const { userId } = await auth.protect()\n  …\n}\n```\nFor non-auth path logic in the proxy, use `config.matcher` and `req.nextUrl.pathname` instead of `createRouteMatcher`. Clerk ships `@clerk/eslint-plugin` with the rule `@clerk/next/require-auth-protection` (ESLint 9+ flat config) plus a Bulk Fixer CLI to find and fix unprotected App Router resources.\n\n## Verify\nThe lint rule passes. Calling a server action directly while signed out is rejected.\n\n## Sources\n- https://clerk.com/docs/guides/development/upgrading/upgrade-guides/migrate-from-create-route-matcher\n- https://github.com/clerk/javascript/blob/main/packages/nextjs/CHANGELOG.md",
