💯 ! I would recommend checking out the Ruff config template that Scientific Python created: https://learn.scientific-python.org/development/guides/style/#ruff

It includes many additional rules that aren't checked by default. Some are too strict, but I found many of them quite useful.

Sounds good, I’ll add them in and check it out.
