How to review AI-generated pull requests with GitHub Copilot

How do I review AI-generated pull requests with GitHub Copilot now

Open the pull request in GitHub, request Copilot as a reviewer, then read the review summary and inline comments before you trust any suggestion. Copilot code review is built to flag issues and propose fixes, but the human reviewer still makes the merge decision.

The practical workflow starts with the PR itself. On GitHub.com, create or open the pull request, then use the Reviewers sidebar and click Request next to Copilot. GitHub says the review usually completes in less than 30 seconds, and the result appears as normal pull request comments that you can reply to, resolve, or hide.

Copilot does not replace code review discipline, it changes where the first pass comes from. By default, Copilot leaves a Comment review, not an Approve or Request changes review, so its review does not count toward required approvals unless your repository, organization, and enterprise settings explicitly enable Copilot approvals. That detail is the part people miss when they assume AI review can satisfy branch protection on its own.

Treat Copilot’s output as a triage layer, not a verdict. GitHub documents that Copilot labels comments by severity, and the review can include suggested changes you can apply in a few clicks. Read the comments, but verify the surrounding code, because a line-level note can be right about the symptom and wrong about the safest fix.

The part people get wrong is checking the comments without checking the diff. A Copilot review can point to a real issue while still missing context from neighboring files, test data, or a design decision that lives outside the changed lines. Open the changed files, compare before and after, then confirm the behavior with tests or local runs instead of accepting the suggestion because it looks plausible.

Use Copilot’s own structure to speed up the pass. GitHub says the review comment overview can include an approval assessment, and individual findings come with severity labels such as High, Medium, or Low. Start with the highest-severity items, then move to medium issues, then low ones, and only after that decide whether the PR is ready for a human approval.

If Copilot suggests a fix, compare the proposed patch with the intent of the pull request before applying it. GitHub lets you accept single suggestions or group multiple suggestions into one commit, and in some setups you can use the Fix with Copilot flow to have the agent implement a response to the review comment. That is useful for routine cleanup, but it still needs a final read because a mechanically correct fix can still be the wrong product decision.

Automatic review changes the timing, not the responsibility. GitHub allows automatic pull request reviews, including reviews triggered on open, draft, or every new push, and the tutorial recommends using Copilot across the pull request lifecycle rather than only at the end. For AI-generated pull requests, the useful pattern is early review on the draft PR, then another review after the final AI pass or human edits.

Re-review after new commits. GitHub says that if new commits are pushed after Copilot approves a pull request, the approval is dismissed, and you can request a new review. That behavior matters for AI-generated PRs because a follow-up edit can fix one issue while creating another, so the second review should cover the final diff, not the earlier conversation.

Check for the limits before you rely on the result. GitHub documents excluded file types, and Copilot code review is not a blanket guarantee across every repo setup. Some organizations need the Copilot policy enabled first, and some review behaviors differ by plan and configuration. When the review path is missing, the fix is usually in settings, not in the pull request.

A good review sequence is simple. First, ask what the PR changes and why. Second, inspect the diff for correctness, tests, and regressions. Third, read Copilot’s comments and suggested changes. Fourth, confirm the final code against your product rules, security checks, and deployment criteria. Fifth, either approve, request changes, or re-run review after the branch changes.

If you want the setup path for a team, GitHub’s configuration page covers automatic review for personal and repository settings, and the lifecycle tutorial shows how to place Copilot at the right moments in the PR flow.

The inconvenient part is that AI-generated pull requests often look finished before they are reviewed. Copilot can surface obvious defects quickly, but it still needs someone to check semantics, edge cases, and whether the change fits the codebase. That is the real review job now, use Copilot to shorten the search, not to skip the judgment.

FAQ

Can Copilot approve the pull request for me?

Yes, but only when Copilot approvals are enabled in the relevant repository, organization, and enterprise settings. By default, Copilot leaves a comment review that does not count as required approval.

Can I request Copilot review through the API?

Yes. GitHub documents that you can request a review by naming copilot-pull-request-reviewer[bot] as a reviewer through the GitHub REST API.

What should I do after Copilot comments on an AI-generated PR?

Open the changed lines, check the surrounding code, run the relevant tests, and decide whether the suggested fix matches the intended behavior. If the branch changes again, ask for a fresh review.

Does Copilot review every file in a pull request?

No. GitHub documents excluded file types, and review behavior depends on repository and organization settings. If a file or review mode is missing, check configuration first.

Where should I start if I want automatic reviews on every PR?

Start in Copilot settings or repository settings, then use the automatic review options GitHub documents for open, draft, and push events. The lifecycle tutorial shows how to place that review at the points that matter most.
