Question

You asked an AI assistant to paginate over a REST API that returns 100 items per page, accumulating all results. It produced this Python:

python
import requests def fetch_all(url):    items, page = [], 1    while True:        resp = requests.get(url, params={"page": page, "per_page": 100})        batch = resp.json()["items"]        items.extend(batch)        if len(batch) < 100:            break        page += 1    return items

It passes your smoke test against a 250-item endpoint. What's wrong, and how would you catch it before it ships?

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.
