I have heard of more than a few horror stories including filesystems lost and force pushes done.

These tools have only been in use for a short time and the current harnesses/system prompts are quite limited. Claude code is mostly limited to your codebase where you have version control. Excel is different.

I foresee that once people hand over more power to full agents there will be some nasty surprises. Im sure there will eventually be demand for some kind of limits
