AI Boosts Pull Request Size 3.5‑Fold, but Bug Detection Drops

A development team integrated AI tools into their code review workflow. The AI assistance allowed them to expand pull request size by 3.5 times. Larger pull requests meant more changes were bundled together. The team observed a decline in the number of bugs caught during review. They attribute the drop to reduced granularity in the review process. The experience highlights a trade‑off between efficiency and quality. The team plans to adjust AI usage to balance speed with defect detection. Observers will watch whether similar AI‑driven scaling impacts other projects.
