Question
You ask an AI to write a JS function that splits a restaurant bill three ways and rounds to cents. It returns `total / 3` rounded with `.toFixed(2)` per person. You notice $100.00 / 3 gives three people paying $33.33 = $99.99, a penny short. You say 'the totals don't add up' and it switches to `Math.round`, same penny gap. The model treats this as a rounding-style problem, not a remainder-allocation problem. How do you re-steer?
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.
