Question
Production alert: p99 latency on your Go search service tripled at 02:14 UTC and error rate is creeping. No human deployed anything overnight, but several AI-agent PRs auto-merged after passing CI. You need to trace the incident to a root-cause change fast. Walk me through how you go from 'latency tripled at 02:14' to the specific AI commit responsible, and how you confirm causation rather than coincidence before you revert.
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.
