Question

You're building a nightly ETL pipeline that pulls events from several upstream sources, normalizes and joins them, and loads a warehouse table other teams query. You want an AI agent to build most of the pipeline in Python. How do you decompose it, what do you keep versus delegate, and where do human checkpoints belong?

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.
