A model found the root cause of a bug before its developer did

A developer says a model found the root cause of a bug faster than he did for the first time, even though the agent had less information than he did.
He describes a common workflow: before a long debugging session, he sends a vague prompt to an agent and then debugges in parallel himself. This time, the agent identified the issue while he was still trying to understand the symptom. The bug turned out to be an int64 overflow during serialization.
