Question

An agent produced 400 lines of Rust implementing a new rate limiter you must ship by end of day. You can't deeply read and reason about all 400 lines in the time you have, but you own the merge. How do you verify enough to ship responsibly under the deadline — what do you read closely, what do you test, and what do you accept on faith?

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.
