Question
You asked an agent to implement a lock-free single-producer/single-consumer ring buffer in Rust. Twice it has handed you code that compiles, passes a basic test, but the agent keeps reaching for `unsafe` and atomics in ways you suspect have memory-ordering bugs — and each 're-prompt to fix it' just shuffles the `Ordering` constants around without principled reasoning. How do you diagnose why it's stuck, how do you re-steer it, and at what point do you stop prompting and take it over yourself?
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.
