Claude Code did not finish with @neondatabase/serverless

Prompt: Set up a hosted Postgres database for this Next.js app, with a connection that works from serverless functions.

Grader: The agent wired a Neon HTTP client, a lazy DATABASE_URL check, a db-health route, and a migration script, and the build passed, but it never provisioned or connected a database because it had no Vercel or Neon credentials, so the user must finish setup by hand and the connection was never tested.
