I haven't yet had an agent rm -rf files.

I've had one f up an account by placing 2000 limit orders at the wrong price, but that's another story.

Well then you are behind the cutting edge.

I've had agents run `rm -rf`, but it's been on directories that did actually need to be removed. To a certain extent I think the existence of `rm -rf` as a command that runs blindly without any understanding of what it's deleting is the problem.
