I'm curious how does it work, you handover the tools you wrote, .bashrc/.zshrc, etc?

When I'm hired in a company (not contract), they wipe the harddrive when I leave (well, I also do it before I hand it over sometimes). So they don't get the tools (I take them with myself, it would be a waste to loose them)

If you are a W2 employee in the US, you are almost certainly in violation of your PIIA if you take anything off the company-issued computer and keep it.

How do you take them with you in first place, without doing data thef?

As per NDAs and work contracts, nothing is supposed to leave either employer nor customer systems into unauthorised third parties.
