With new organization runner controls, Copilot content exclusion support, and the removal of the character limit on repository custom instructions, Copilot code review is now easier to tailor to your needs within your repository and organization.

With the release of Copilot code review’s agentic architecture, we announced that Copilot code review is powered by GitHub Actions. By default, Copilot code review runs on the standard GitHub-hosted runner, but teams can configure self-hosted or large runners for more control over the runner type. To support ease of setup of custom runners, Copilot code review’s runner type can now be configured at the organization-level, meaning that one configuration can apply to all repositories within the organization.

Organization admins can now:

Set Copilot code review’s default runner to be automatically used across all repositories, without requiring each repository to be individually configured.

Lock the runner setting so the organization default overrides any individual repository configurations.
