Original script:

  ssh-keygen -t rsa -f ~/{0}

Chatgpt's version:

  ["ssh-keygen", "-t", "rsa", "-f", keyfile, "-N", ""]

It added `-N ''`, which means don't set a passphrase—a second potential security downgrade.

Ok, fair enough, I was thrown by your use of the word hallucination, which to me is used to describe picking things that don't exist, like if it had done "ssh-keygen -t rsa --add-public-keyfile-to-gitrepo-and-commit". In this case I had asked it to automate the do-nothing script, so I'd call this more of a "design decision" than a hallucination.
