GitHub Copilot Code Review Now Handles Bot PRs and Giant Diffs

Copilot code review now reviews pull requests it used to skip: bot-authored PRs, Copilot cloud agent PRs, and very large diffs. You can now also tell GitHub why you resolved a comment.

What shipped? Two previously blind spots are now covered. Bot-authored PRs (including Copilot cloud agent) get a full agentic review, and the old 300-file or 20,000-line cap is gone — any PR, any size.

What changed? For bot-authored PRs where no individual Copilot license exists to attribute the review, organizations can enable the policy to let members without a Copilot license use code review — billing goes to the org. For large PRs, the size limit simply no longer applies. Separately, when resolving a Copilot code review comment, a dropdown now lets you pick a reason: "Addressed", "Won't fix", or "Incorrect" — sending signal back to improve the product.

Why a builder cares? If your team uses automation, agents, or Copilot cloud agent to open PRs, those were a review blind spot. Large refactors touching hundreds of files were capped. Both edges are now covered. The resolution reasons also give the product team direct feedback on false positives — the kind of data that makes the next version sharper.
