i had this same thing happen to me! I ended up making a bash script called "c" in my ~/bin folder which is in my path. Because the alias kept getting removed! It was one of the first times I thought "man, AI will start doing more and more 'stuff' without asking me, this is just the start."

Not to state the obvious but this is the users fault, not claude code's.

When I use it, I do so on a dedicated cloud instance with a backed up codebase, and even then I still read what it proposes before approving.

Running a script that can make arbitrary modifications to your machine, on your local or otherwise important machine, is sort of obviously a bad idea.

It's very disturbing that there are devs who think this behavior is even remotely acceptable.
