As far as i understand the intended way to use a list type parameter would be like this:

$ python app.py --command arg1 --command arg2
['arg1', 'arg2']

If you really want to use comma separated strings you could do the following:

from typing import Annotated

import typer

def comma_list(raw: str) -> list[str]:
    return raw.split(",")


def main(
    command: Annotated[list, typer.Option(parser=comma_list)],
):
    print(command)


if __name__ == "__main__":
    typer.run(main)
$ python potato/main.py --command "hello","world"
['hello', 'world']

Note that using list[str] instead of list for the command parameter seems to attempt some type conversion magic resulting in a nested list so this isn't perfect. Personally I would just keep it simple and do something like this instead:

import typer


def main(commands: str = typer.Option()):
    cmd_list = commands.split(",")
    print(cmd_list)


if __name__ == "__main__":
    typer.run(main)

from typer.
