Question

You're directing an AI agent to write a Bash script that backs up a Postgres database nightly, uploads the dump to object storage, prunes backups older than 30 days, and alerts on failure. Write the spec that makes it production-safe on the first pass. What does a quick 'write a backup script' prompt get dangerously 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.
