Agree that shared understanding is the hard part. Bugbots find bugs. Review is how the team stays aligned on the change. Visuals help a lot for that first pass.
Another cause of burnout for us was noisy bot comments on top of diffs that already look AI-written. We only want findings we would actually act on.
I checked your skill and looks really good, however I find it to be very complex already, we do many PRs and maybe visualizing graphs for every one is too much. I think ideally could filter the complexity of PRs and adapt the visualizer depending on that, being just two sentences on some and complete graphics on some.
I myself created Revix AI and we internally created some rules that we found that served educational purpose as well, we started linking that rules to the PR comments that Revix did so the devs could access that information if they wanted. Following what I said, it's always better to keep it simple and only expand if the human wants to get deeper or if the pull request requires it.
