Question
You're a Go engineer with deep concurrency experience. An AI agent helping you build a worker pool insists that because Go channels are 'thread-safe,' you can freely have multiple goroutines close the same channel for clean shutdown, and it shows code that does exactly that with full confidence. This is squarely your area. Explain how you handle the advice and what it reveals about catching AI errors in your strongest domain.
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.
