Review AI-generated pull requests with evidence, not confidence: verify that the code works, solves the requested problem, is maintainable and safe, and has a human owner willing to approve the merge. The four rounds below organize those checks into a practical workflow; they are an editorial framework, not a GitHub standard.

Round 1: Does the change work?

Begin with executable evidence. Read the diff, then run the checks the project uses to establish whether the change builds and behaves as expected. GitHub’s guide to reviewing AI-generated code recommends compiling or building where applicable, running automated tests, and using static analysis.

  • Build or compile the affected project or component.
  • Run relevant automated tests, including tests added or changed in the pull request.
  • Run the project’s static analysis or lint checks.
  • Inspect new warnings and errors instead of treating a green overall status as proof that the diff is correct.
  • Ask what important behavior is not covered by the existing tests, and add or request tests where needed.

A passing test suite establishes only that the tested cases passed. It does not establish that the pull request meets the request, covers every edge case, or preserves behavior outside the tests.

Round 2: Does it solve the right problem?

Compare the implementation with the issue, request, or acceptance criteria—not with what the generated code appears to be trying to do. Check that every requested outcome is addressed and that the change has not introduced unrelated behavior.

Use repository context to judge whether the solution fits the project: consult its README and documentation, follow established conventions, and look at recent pull requests that changed similar areas. GitHub’s review guidance recommends checking requirements, architecture, and conventions as part of the review.

  • Trace each acceptance criterion to the code and, where possible, a test.
  • Check whether the change belongs in the affected module and respects its interfaces and architectural boundaries.
  • Look for duplicated logic or a new pattern that conflicts with documented or established project practices.
  • Confirm that the pull request description accurately explains what changed and what did not.

Round 3: Is it maintainable and safe?

Read the implementation as code a teammate will need to understand and maintain. Generated code can look plausible while being syntactically or semantically wrong, failing to resolve the underlying issue, or introducing a security vulnerability. GitHub warns that these risks warrant careful review and testing, particularly for critical or sensitive applications in its responsible-use guidance for agents.

Readability and edge cases

  • Check whether names, control flow, error handling, and abstractions make the intended behavior clear.
  • Consider boundary values, empty or malformed input, failure paths, and state changes that tests may not exercise.
  • Look for unnecessary complexity, repeated logic, or code that appears unrelated to the requested outcome.

Security findings and proposed fixes

Do not accept a generated security fix merely because it removes a finding. GitHub’s guidance for AI security and quality features advises reviewers to confirm that a proposed fix preserves intended behavior and that CI passes. Review the relevant behavior yourself, then test it.

Automated detection also has limits: GitHub notes that AI secret detection may miss secrets in test code. Treat scan results as useful signals, not a guarantee that the change contains no exposed secrets or other security problems.

Dependency changes

Inspect every added or updated dependency. Check whether it is necessary, supported, and appropriate for the project, and whether its behavior or security implications fit the change. GitHub’s security guidance specifically calls for assessing dependencies for security, support, and behavior.

Round 4: Can a human own the merge?

Resolve substantive review feedback, evaluate the final diff after revisions, and ensure the right people have reviewed the change under the team’s normal process. A new push can alter the behavior or introduce regressions, so review the updated changes rather than relying only on an earlier approval.

AI review can help surface issues, but it does not take responsibility for acceptance. GitHub says reviewers should verify Copilot code-review feedback and supplement it with careful human review so the code meets requirements in its responsible-use documentation. A human should make the merge decision and be able to explain why the change is acceptable.

Where AI review fits in the workflow

Automated checks, AI feedback, and human review answer different questions. Tests and static analysis provide evidence about specified behavior and detectable issues; project-context review checks intent and fit; AI review may suggest things to inspect; a human remains accountable for deciding whether the whole change is ready. GitHub presents these as complementary parts of review, not interchangeable guarantees.

For teams using GitHub Copilot code review, repository-wide instructions can be placed in .github/copilot-instructions.md, and path-specific instructions can tailor guidance to parts of a codebase. GitHub’s Copilot code-review documentation says that new pushes do not automatically trigger another review by default unless configured; a reviewer can request one manually. It also notes that comments may recur during re-review. These details describe GitHub’s product behavior and can change, so check the current documentation when configuring a workflow.
