there is no requirements.txt and requirements-test.txt in this repo right?
except for requirements-bootstrap.txt? so should i create them

[plannigan]

All of the dependencies are in pyproject.toml. The library dependencies are here. The development dependencies are within the tool.hatch.envs sections.

Everything seems to be working, except the codecov token. So should i put up a PR for you to review? @plannigan.

Here is the run i tried. Run

[plannigan]

Yes. Once you think things are in a good state, submit the PR and I'll take a look.
