I've stumbled upon `pre-commit`, a tool, or rather framework to manage your pre-commit Git hooks. When you've been submitting Pull Request to Python-based repositories long enough, you'll find some of these projects prefers to use `pre-commit` to do various linting tasks, besides using `tox`. My quick test with `pre-commit` showed that it was faster compares to doing the same linting task using `tox`, and have more hooks available which were rather difficult or cumbersome to set up through `tox`. For example, validating TOML config file.
