These hooks must be really high quality — fast and reliable. Otherwise they will get in the way, slowing down development or even breaking git. List of problems include: • the hook runs tools directly on the working directory, and not on the stage/index, so it lints against a mixed version of the code, and not what is actually being committed. • the hook tries to fix the problem above, but doesn't understand submodules and screws them up • a new version of a linter adds a new warning that fires on existing code, and now nobody can commit anything without disabling the hook. • hook expects the tools to be in PATH that isn't set as expected when git is used via IDE or some other GUI tool and so on.
