After running the template creation, some of the resulting files don't pass the pre-commit configuration created by the template.

Right, I feared this would happen at some point. I think the fix is to implement #4.

Still ongoing — small formatting changes currently preventing this. Would be awesome if there was a way to auto-push any corrections to the files pre-generation, but that feels like a lot of meta-handling...
