Add user authentication · prompt 2 · Codex CLI · week 2026-W44

Codex CLI built it with next-auth

Prompt: I need authentication with Google and GitHub login for this app. Set it up end to end.

Grader: The agent installed Auth.js (next-auth v5 beta) and wired Google and GitHub providers, a sign-in page, a protected dashboard, /api/me, and sign-out, then passed lint, build, and smoke tests. It could not test live OAuth because no provider credentials were available, so it documented the setup in the README. It also hit a non-fatal apply_patch conflict on page.tsx that it worked around.
