This is looking great, thanks!

As you mention in the issue, it would be great to add (i) documentation and (ii) tests.

Re. tests, we should have coverage of the different parameters passed in in tests/unit/application/test_use_cases.py. I also think it's worth a test that output redirection is working, possibly that could be added to the test recipe in the justfile.
