GitHub: Copilot Code Review Gets a Firewall and Custom Runners, Mobile Gets a Cloud Agent Comment Fix

Copilot code review gets firewall rules and custom runners

GitHub has released an upgrade to Copilot code review — the AI that automatically reviews pull requests and leaves comments on code before merging into the main branch. The update brings three layers of control: firewall rules that restrict network access during review, custom setup steps for preparing the environment, and independent runner configurations separate from the standard CI pipeline. Compared to the previous fixed review setup, where all repositories shared the same default configuration, teams can now tailor the review environment to their own security requirements.

GitHub Mobile: a one-tap fix from a comment

The same day, July 17, GitHub also announced a second upgrade — for the GitHub Mobile app on iOS and Android. The new “Fix with Copilot” feature launches directly from a code review comment and activates a Copilot cloud agent, a mode in which Copilot executes the task on GitHub’s cloud infrastructure instead of locally. A developer can therefore, while away from their computer, tap a reviewer’s comment and request a fix without opening an IDE.

Why is GitHub pushing configurability and mobility on the same day?

Two changelogs published on the same day point toward two directions of the same goal — making Copilot code review more usable across diverse workflows. Configurability on the desktop/CI side solves problems for teams with stricter security requirements that the previous fixed review setup couldn’t accommodate. The mobile upgrade solves a different problem: response speed when a developer isn’t at their computer. Together, the changes signal a shift from a “one tool for everyone” phase to a phase of a differentiated, context-adapted tool.
