Question
You asked an AI assistant for a JavaScript helper to format a phone number, and it handed you 15 lines using a regex and a library import you've never seen: `import phoneFmt from 'phone-formatter-pro'`. It looks clean and you're tempted to paste it in and move on. Before you do, what do you actually check, and in what order — without just running it and hoping?
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.
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.
