      # The file-length hook delegates to the shared gate in kuhyx/utils, which
      # a runner does not have at $HOME/utils. Check it out and point the shim
      # at it via UTILS_ROOT, or `pre-commit run --all-files` fails on a
      # missing checker rather than on anything in this repo. `.utils` is in
      # the gate's own EXCLUDED_DIRS, so it does not lint itself.
