GitHub announced expanded Copilot code review settings on September 23, 2026. The change adds a dedicated personal settings page for automatic reviews and default review effort, while enterprise administrators can set a default effort level across organization-owned repositories. For QA teams, this is less about switching on another reviewer and more about making review automation predictable, measurable, and safe to roll out.
What changed in Copilot code review
According to GitHub’s announcement, the personal code-review settings page is now available on every Copilot plan, including Copilot Business and Enterprise. A user can enable automatic reviews for pull requests they create or coauthor, choose whether to include new pushes and draft pull requests, and set a default review effort of Lite or Balanced. A manually requested review can still use a different effort for that one pull request.
At the enterprise level, authorized administrators can set one default effort for organization-owned repositories. Organization and repository settings can override that inherited value. GitHub describes the feature as generally available; the exact controls and permissions should still be checked in your own Copilot settings before changing a team-wide policy.
Why this matters for QA engineers
Automatic AI review changes the test signal arriving on a pull request. Enabling reviews on creation, new pushes, or drafts affects when findings appear, how often they are refreshed, and whether developers see incomplete test work as review-ready. An enterprise default also means the same pull request can behave differently after a policy change even when its test suite has not changed.
- Noise control: Draft and push triggers can multiply review events. Confirm that findings remain actionable rather than duplicating ordinary CI feedback.
- Coverage boundaries: Copilot review is an additional signal, not proof that UI, API, accessibility, performance, or security tests passed.
- Comparable trials: Review effort should be treated as a test variable. Compare Lite and Balanced on the same representative pull-request set before standardizing.
- Policy traceability: Record whether the setting came from an individual, repository, organization, or enterprise default when investigating a missed or noisy finding.
A focused QA rollout checklist
- Start with a representative repository. Include unit-test changes, test-only pull requests, a flaky-test fix, a configuration edit, and a change with a deliberately seeded defect that reviewers are permitted to use.
- Capture the starting policy. Document the personal trigger selections, repository or organization overrides, and inherited enterprise effort before the trial.
- Test each trigger deliberately. Create a draft pull request, move it out of draft, push a follow-up commit, and manually request a review. Verify which events initiate a review in your environment.
- Compare review effort against a human baseline. Track useful findings, false positives, repeated comments, time to first finding, and defects missed by Copilot but caught in human review or CI.
- Keep merge gates independent. Required tests, branch protection, code owners, and human approval rules should remain the authority for release decisions.
Questions to settle before enabling automatic review
- Should draft pull requests receive automated feedback, or should that wait until the author marks the work ready?
- Do new pushes trigger a fresh review often enough to be useful without creating comment churn?
- Which review effort is appropriate for high-risk services versus routine maintenance work?
- Who owns exceptions when an organization or repository needs an override?
- How will the team distinguish AI review observations from verified test failures and release blockers?
Keep the evidence loop intact
The useful outcome is not simply more comments. It is a review workflow where reviewers can trace a finding to a change, reproduce it, and confirm it with the right test. Pair Copilot findings with pull-request test evidence, CI logs, and a clear disposition such as fixed, accepted risk, or false positive. That gives QA teams a way to evaluate the settings change from real outcomes instead of relying on activity volume.
