Hey @narrow-vegetable-37489! Git is not really safe to use right now with the Rules API, we break the engine's sandbox when using it. The only place we use it is before the normal rules have fully kicked in,

specs_calculator.py

. https://github.com/pantsbuild/pants/issues/13724 tracks this - if you're interested, we'd be happy to write instructions Re different backends, it sounds like

breaking

might align with our notion of

check

than

lint

-

check

is intended for heavier weight-things like typechecking and compilation
