Question
You're mid-task with an AI agent optimizing a hot gameplay loop in a C++ game engine — you've gotten the frame time down but you're handing off to another engineer because it's blocked on a profiling question. Write the handoff so they can continue the AI-assisted work without regressing what you've done. The codebase has subtle constraints: certain systems must run in a fixed order, and some 'obvious' optimizations break determinism needed for the replay system.
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.
