Hi, I am new in this repo :) Could you please advise about those failing checks? Thanks!

Hey @cupofcat, it looks like you're running into a lint and type issue. It looks like you may be able to reproduce the lint issue locally by using pre-commit run --all-files. I believe you can reproduce the type issue locally by running hatch run mypy:run.

@cupofcat if you have issues with fixing the failing type check, let me know and I can fix it for you.

Code looks good, let's wait a bit, if someone else has an opinion on it. if not, then I'll merge it next week.
