  nix-shell --run 'MY_SHELL_NAME=foo zsh'

will allow you to tag the shell with a custom environment variable.

If you want to update the prompt, you should probably play around with
shell prompt variables (like PS1 in bash):

My first reaction on seeing your very first mail was that you were
probably having issues with processing of ASCII terminal codes.
Unfortunately, I don't have any clear suggestions.

Have you tried running the commands in different terminal emulators?
