Question

You need a Go worker pool that processes a stream of jobs with a bounded number of goroutines, graceful shutdown on SIGTERM, and a cap on in-flight work. Write the spec you'd give an AI agent. Which concurrency guarantees must you spell out, and what does a casual 'write a goroutine worker pool' prompt get subtly wrong?

What a strong answer looks like

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.
