Question

An AI assistant wrote this Python worker that pulls cached task definitions from Redis and reconstructs them. The values were written by an upstream service. It runs cleanly in dev. Review it.

python
import pickleimport redis r = redis.Redis(host="cache", port=6379) def load_task(task_id: str):    raw = r.get(f"task:{task_id}")    if raw is None:        return None    task = pickle.loads(raw)    return task.run()
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.
