Question

You need an AI agent to add OAuth2 'login with GitHub' to a Go web app that currently uses session cookies. Sequence the build into verifiable steps, and decide which steps you review closely vs. let run. Security is the whole point here, so be specific about where human judgment is non-negotiable.

What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.

Describe your solution

Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.

Run or narrate your approach, then ask the coach.
