Whatever the agent was actually doing, the real failure is that it had destructive write access to the only copy of finished work. That's a permissions problem before it's an AI problem — no automation, human or otherwise, should be able to hard-delete production assets without a human confirming the destructive step.
The fact that the season is just gone also tells me there was no immutable backup or soft-delete tier behind it, which is rough for a broadcast workflow where the footage is irreplaceable. Agents are getting broad tool access by default right now, and this is the cautionary tale for giving them delete rights alongside read rights.
