This app's agent prompt is a derivative work of one agent skill. It paraphrases and adapts its guidance;
it does not reproduce the skill or its reference files verbatim.

   Modifications: the skill's model and patterns (Server Components by default, 'use client' only where
   needed, no hooks in Server Components, the server-to-client serialization boundary, fetching in Server
   Components rather than Client Components, Server Actions for mutations with revalidation, Suspense and
   loading.tsx for streaming, the file conventions, metadata and route handlers) were restated as
   deterministic browser checks (nextkit.js) and as the audit and fix lanes of this app's prompt. The
   Next.js 15/16 request-API grading, the Server Action authorization check, the exact before/after edit
   contract, the re-check of every edit and returned file and the changes list tied to the page's flags are
   additions of this app.

The browser-side checks (nextkit.js), the reconciliation (recon.js) and the rest of the page are original
to this app. Next.js is a trademark of Vercel, Inc.; this app is not affiliated with or endorsed by Vercel.
