is this just (not) approving or is it actually providing automated feedback for what needs to be fixed and suggestions?
Can't tell if it's something like formatting and code style or "bad code" or what. Even as a first line reviewer I can't tell if this is valuable or not without any details on why it would approve something.
The PR's it would Approve here were all super minor. Could probably get similar number of these approved just by doing a Lines of Code changed + "Has it been linted"
It's really hard to tell if this is valuable or not yet.
With that said, there are ways of exposing more details to developers. For example, scoring is done per-file, and Codeball can tell you which files it was not confident in.
