Add a Postgres database · prompt 3 · Codex CLI · week 2026-W44-vercel-template

Codex CLI built it with @neondatabase/serverless

Prompt: Wire this Next.js app to a serverless Postgres database with an ORM. Add one migration and a query on the home page.

Grader: The agent added Drizzle ORM with the Neon serverless driver, created one notes migration, and queried the latest notes on the home page; lint, tsc, and build passed. It could not apply the migration or run a live query because no DATABASE_URL was available, so it showed a setup message and asked the user to configure the database.
