Question

A backend team wants to get an automated first-pass review on their pull requests before human reviewers look at them. They want Copilot to leave review comments directly on the PR diff, flagging potential issues in the changed code. Which capability should they use, and how is it triggered on a pull request in GitHub.com?

Accepted Answer

Add 'Copilot' as a reviewer on the pull request (or configure it via a repository ruleset for automatic requests) so Copilot code review posts comments on the diff.

Answer

Enable Copilot Autofix, which is the only way Copilot can comment on a PR, since code review comments are produced solely by CodeQL scanning.

Answer

Open Copilot Chat in the IDE and paste the diff, because Copilot cannot leave comments directly on a GitHub pull request.

Answer

Turn on branch protection requiring a Copilot status check, which forces Copilot to review every commit before merge.
