Question

You need to add client-side validation to a signup form's password field in a React app: minimum 8 characters, at least one number, and it must match the 'confirm password' field. You're going to ask an AI assistant to write it. Write the prompt, then point out one acceptance criterion a vague prompt would almost certainly miss.

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.
