@pikesley I wouldn't doubt it. Without knowing exactly how they prompted, or what the source data looked like, can't say whether just _deleting everything_ (which this particular line appaers 2 do) at some point is valid or not.
Its one thing to ask ai to whip you up a script that does something, its another thing to execute it blindly - on an irretrievable single source of valuable data - without reviewing or testing it first.
That's... like common sense.
