Are `statix`, `deadnix` and `prettier` really working?

Or I always write perfect code (🤔) or they are useless because they don't catch interesting cases or something is misconfigured.

Does it integrate with pre-commit checks? Would be cool if formatter run on pre-commit (got used to that suprisingly quickly).

EDIT: I think these all run in checks but not pre-commit.

• treefmt is configured to run it
• it runs on pre-commit
• it actually changes the file but then fails. i don't like it. it should not change the files when checking correctness in pre-commit hook, only on nix fmt
