I've been running GPT5.x fully unconstrained with effective local admin shell for over $500 worth of API tokens. Not once has it done something I'd consider "naughty".

It has left my project in a complete mess, but never my entire computer.

  git reset --hard && git clean -fd 

That's all it takes.

I think this is turning into a good example of security theatrics. If the agent was actually as nefarious as the marketing here suggests, the solution proposed is not adequate. No solution is. Not even a separate physical computer. We need to be honest about the size of this problem.

Alternatively, maybe Claude is unusually violent to the local file system? I've not used it at all, so perhaps I am missing something here.
