Question
You're implementing a novel order-matching algorithm for a low-latency trading engine in C++: price-time priority with a custom pro-rata allocation rule that only your firm uses, and it must reconcile bit-for-bit with an existing reference implementation. A teammate suggests letting an AI agent write the whole matching loop from your one-paragraph description. Walk through whether you'd delegate this, and if not, what failure modes make an AI assistant the wrong primary tool here.
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.
