Question
A user reported that uploading a file over 5 MB sometimes fails with a 500. You gave the stack trace to an AI agent and it returned a fix that wraps the upload handler in a try/catch and returns a friendly 413 instead. The error stopped appearing in your manual test. How do you decide whether this fix addresses the root cause or just hides the symptom — before you merge it?
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.
