I use Vim as my diff and merge tool for Git. When running Gdiff in a file in Vim, I get the split window with diffs displayed with no issues (linting). When I run the difftool alias for Git from the command line, it opens up a similar split, but this time index version of the file is pulling from a temp directory /private/vars/folder and ALE lints the file. It seems that because this file is outside of the repo it doesn't use the rubocop config and seems to pull from a default set of rules.

Ideally, ALE wouldn't lint files when viewed via vimdiff or Gdiff.
