This is a serverside pre-PR hook for an analyzer, as I understand it.

I was hoping this was a code review tool that allows you to modify the PR without making a commit-merge-push loop, which could have approved changes automagically pulled locally (for the loop). This would save a TON on small edits that many PRs require, including any additional comments that people might want to add to code that come up during PR...modern PRs is where context goes to die.
