Question

An AI wrote this blue-green deploy script. It exits 0 and the pipeline goes green, but one morning prod was serving a broken build while CI reported success. Walk through how this script lies about success.

bash
#!/bin/bashset -e build_artifact=$(curl -s https://artifacts.acme.io/latest | jq -r .url)curl -s "$build_artifact" -o /tmp/app.tar.gztar xzf /tmp/app.tar.gz -C /opt/app health=$(curl -s localhost:8080/health | grep -c '"status":"ok"')if [ $health -gt 0 ]; then  echo "Healthy, promoting"  systemctl restart appfiecho "Deploy complete"
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.
