Question

You asked an AI assistant for a SQL query: "count how many users signed up in each of the last 7 days." It gave you a query that runs and returns rows. Before you put it in a dashboard, how do you sanity-check that the numbers are actually right — not just that the query executed?

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.
