Question
You need a small Bash logging helper sourced by other scripts: functions `log_info`/`log_warn`/`log_error` that timestamp messages, write to both stderr and a logfile, and respect a `LOG_LEVEL` threshold. You'll ask an AI agent to write it. Draft the prompt/spec — constraints, edge cases, acceptance criteria — for a first-try-correct result. What does a lazy prompt ("add some logging functions to my bash script") get wrong?
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.
