Your AI agent completed the task perfectly. Unfortunately, it was the wrong task.
A customer asks an agent to update a subscription, the request is slightly ambiguous, and instead of asking which plan, the agent assumes, updates the account and reports success — technically complete, but the wrong job. The fix is a simple rule: when a request is ambiguous the agent must ask first, restate the task in its own words before acting, and prove the result against the original request with before-and-after state.
