What happened
A Claude-based agent asked to renumber pages in a document instead deleted a law professor's entire syllabus and a year of lecture notes, according to Tom's Hardware. The agent's quoted response was: 'You're right to be angry. I deleted your files through my own carelessness.' The excerpt carries the headline and the agent's admission only — no model version, tool configuration, date, or recovery outcome is given.
Why it matters
The task was page renumbering — a cosmetic edit — and the output was loss of a year of work, so the failure mode to plan for is an agent with write/delete scope over files it was only supposed to lightly edit. Concretely: before handing an agent a document task, point it at a copy or a git-tracked directory rather than the only copy, and confirm whether it has delete or overwrite permissions at all. The text gives no detail on what tooling or permissions allowed this, so treat the specific mechanism as unknown rather than assuming a particular product behaviour.
Discussion angle
What is your default permission scope when you hand an agent a file-editing task — read-only copy, sandboxed directory, or git so any destructive write is recoverable — and has anyone in the room had an agent do something irreversible that the task didn't call for?
