GitHub Copilot Code Review Now Supports Bot, Cloud Agent, and Large Pull Requests

GitHub CopilotView original changelog

GitHub Copilot code review now covers three pull request types it previously couldn't handle. It can review bot-authored pull requests with the right policy enabled, billing usage directly to the organization instead of requiring a Copilot-licensed human author. It also delivers a full agentic review on Copilot cloud agent pull requests, and the prior cap of 300 files or 20,000 lines of code no longer limits which pull requests can be reviewed at all.

Key Takeaways

  • Bot-authored pull requests can now be reviewed by Copilot when the right policy is enabled, with usage billed to the organization instead of requiring a human license holder.
  • Copilot cloud agent pull requests now receive a full agentic review instead of the previously limited automatic check.
  • The old 300-file or 20,000-line cap on reviewable pull requests has been removed entirely.
  • Teams relying on automated dependency or bot workflows can now get consistent AI review coverage where they previously had none.
  • Admins need to opt into a policy setting to enable review of bot-authored pull requests — it isn't on by default.
  • This continues a steady 2026 pattern of GitHub removing scope restrictions from Copilot code review one release at a time.

Expanded Pull Request Coverage

GitHub Copilot code review has removed several longstanding restrictions on which pull requests it can automatically review, closing gaps that previously left entire categories of pull requests without AI-assisted review.

Bot-Authored Pull Requests

Previously, when a pull request was authored by a bot and a review was requested automatically, there was no Copilot-licensed account to attribute the review to, so the review simply didn't happen. With the appropriate policy now enabled, organizations can allow Copilot code review to review these bot-authored pull requests, with usage billed directly to the organization rather than to an individual license holder. This closes a common gap for teams that rely heavily on automated pull requests, such as dependency update bots, since those pull requests can now receive the same AI review coverage as human-authored ones.

Copilot Cloud Agent Pull Requests

Pull requests created by Copilot's own cloud agent previously received only limited automatic review functionality. GitHub Copilot code review now performs a full agentic review on these pull requests, giving them the same depth of analysis as any other pull request in the repository rather than a reduced-scope check.

Large Pull Requests

Copilot code review previously stopped short on very large changes, capping reviews at 300 files or 20,000 lines of code. That limitation no longer applies, meaning large refactors, big dependency bumps, or major feature branches can now receive a complete Copilot review instead of being skipped or only partially covered.

Together, these changes mean fewer pull requests fall outside Copilot's review coverage, regardless of who or what authored them or how large the change is.
