Use click methods which gives a better output result, and for consistency and potentially using an other interface. - [`fail()`](https://click.palletsprojects.com/en/stable/api/#click.Context.fail) - `abort()` - `exit()` - `close()` Write function in `tools.py`: ```py from rich_click import click def fail(message: str) -> None: click.get_current_context().fail(message) ``` The context has to be defined in the function otherwise it does not work.
