Question

You want a small Bash script that deletes log files older than 30 days from a `/var/log/myapp` directory, to run as a daily cron job. You're about to ask an AI assistant to write it. Write the prompt, and name the one constraint you must include so a vague prompt can't produce something dangerous.

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.

Describe your solution

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.

Run or narrate your approach, then ask the coach.
