exit() is not a built-in function and is only defined if the site module is imported during Python's initialization (which, for example, can be disabled with -S option passed to the interpreter). You should use sys.exit() instead:

    sys.exit(os.spawnv(os.P_WAIT, ruff, [ruff, *sys.argv[1:]]))

Fixed, thanks. (Ruff should have a rule for this!)

I would like to implement it.
In which rule group would this be added?
