We've already soft launched the next step toward this to some existing Graphite users, so I'm fine sharing!

We're adding an agentic chat sidebar to the pull request that can help you gather context to understand a PR and make pre-merge changes without needing to leave the PR page. Open beta next week.

We're only going to spend more and more time looking at diffs as the amount of them increases, so the tools that we use here need to evolve as well. "AI code review" should be an interactive experience that directly builds on how code is reviewed today, not just a bot that comments on your PRs.
