Run a Risk-Based AI Pull Request Review
Review a pull request with AI while prioritizing requirements, security boundaries, verified findings, missing tests and human approval.
What you will have at the end
A prioritized review record whose findings link to requirements, changed code, evidence, verification results and a final human disposition.

Testing scope
What was actually exercised, and what still requires verification in your own environment.
The dry run used a synthetic pull request containing one functional regression, one secret-like test fixture, one style-only issue and one false-positive bait. Codex produced, challenged and dispositioned findings. GitHub Copilot and a live GitHub repository were not used.

Steps
Step 1: Establish requirements and risk areas
Read the issue, acceptance criteria, architecture context and repository guidance before the diff. List high-impact boundaries such as authentication, authorization, secrets, personal data, payments, migrations and external side effects. Mark missing requirements as review uncertainty. Do not ask the AI to infer the intended behavior from changed code alone; code can consistently implement the wrong requirement.
Step 2: Inspect diff scope and change shape
Identify changed components, generated files, dependency changes and paths not covered by the visible diff. Check whether the change is small enough to review coherently and whether unrelated refactoring hides behavior. Record entry points and affected data flows. If the pull request exceeds safe review scope, request a split or staged review rather than relying on a broad summary.
Step 3: Request requirement and security reviews
Run the diff-review prompt with explicit requirements and the security prompt with named data boundaries. Require each finding to identify file, line or code path, expected behavior, observed behavior, impact and a verification step. Treat output as candidate findings. GitHub documentation itself warns that AI review can miss problems and produce inaccurate feedback, so no finding is accepted without inspection.
Tool: GitHub Copilot
Step 4: Verify and prioritize every finding
Open the cited code and reproduce the concern with a test, type check, static analysis or documented reasoning. Classify findings by user or system impact rather than tone. Reject style comments that do not violate repository rules, and record false positives so the final review is auditable. Escalate security uncertainty instead of lowering it because the tool sounds confident.
Step 5: Challenge the first review and add missing tests
Use the challenge prompt with the first review, requirements and diff. Ask what the review assumed, what changed paths remain unexamined and which failure modes lack tests. Add focused tests for verified regressions and important boundaries. Confirm a test can fail for the defect it is meant to catch. A test that passes before and after the fix may not protect the requirement.
Step 6: Resolve, accept or block with human approval
For each verified finding, record fixed, accepted risk, false positive or follow-up, with evidence and owner. Rerun affected checks after edits and inspect the final diff, not only the earlier one. A qualified human reviewer makes the merge decision. Store unresolved risk in the pull request so later maintainers do not mistake silence for validation.

Editorial validation record
Illustrative scenario reviewed on Oct 3, 2026. This is not proof that the named third-party integrations were run.
- OutputIllustrative scenario: findings challenged
The synthetic review correctly retained the functional regression and secret-like fixture for action, downgraded the style-only issue and rejected the planted false positive after code inspection. A focused regression test was added to the review record.
- DatasetTesting limitation
The pull request and code were synthetic. The review sequence ran in Codex on 2026-10-03; GitHub Copilot, branch protections and a live repository were not used.
