Question

You need a tiny Go function that checks whether a string is a valid US ZIP code (exactly 5 digits). You want it to use only the standard library and be easy to read. You're about to prompt an AI assistant. Write the prompt, and explain why naming your constraints up front saves you a round-trip.

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.
