AI tools change how code arrives in your review queue. Diffs are bigger and faster. They often come from AI rather than human thought.
This is not a problem unless your review process stays the same.
Research shows AI coding tools can increase code churn and decrease reuse. One study found AI-generated code often has more security vulnerabilities than human code.
AI tools help teams ship faster. But treating every AI pull request the same as a human one creates bottlenecks or hidden defects.
You need a tiered approach. Match your review effort to the risk of the change.
Use these three signals to decide the review tier:
• Code Origin: Did a human use a small AI suggestion, or did an AI draft the whole feature? AI code often looks correct but lacks deep logic. • Change Scope: How many lines changed? Large diffs have more surface area for errors. • Blast Radius: What does the code touch? Changes to authentication or payments are high risk. Changes to documentation are low risk.
Assign tiers based on these signals:
• Tier 1 (Skim): Use for human-only code or small AI-assisted scripts. One reviewer checks for hardcoded keys. Turnaround: 4 hours. • Tier 2 (Scrutinize): Use for moderate AI changes or larger human diffs. One reviewer checks logic and test coverage. Turnaround: 24 hours. • Tier 3 (Sign-off): Use for any critical code or large AI-generated diffs. Two reviewers, including a tech lead, must sign off. Security scans and rollback plans are mandatory. Turnaround: 48 hours.
Blast radius is your override. A tiny AI change to your payment logic is always Tier 3.
You can automate this. Use a GitHub Actions workflow to read diff sizes and file paths. Assign labels like review/tier-1 or review/tier-3 automatically.
This system is not a penalty. It is a way to ensure the right humans give the right attention to the right code.
Build the matrix. Add the labels. Use the data to adjust your thresholds over time.
