Code Review When Half the Diffs Are From Agents

May 29, 2026 · 6:14 PM UTC ·5 min read · 0 reactions · 0 comments · 32 views

TL;DR · WeSearch summary

The article discusses the challenges of code review in the context of agent-authored code. It highlights the need for a shift in review practices as agents produce code faster than humans can read. The author emphasizes the importance of focusing on the overall shape of changes rather than line-by-line reviews in many cases.

Key facts

▪Code review was originally designed for human authorship, where both writing and reviewing occurred at a similar pace.
▪With the introduction of agents, the speed of code production has outpaced the ability of reviewers to keep up, leading to potential bottlenecks or rubber-stamping of reviews.
▪The review process must adapt to focus on higher-level questions about the changes made, rather than scrutinizing every line of code.

The ratio held. Reviewers could plausibly read every line of every change without becoming the bottleneck. The practice scaled because both sides scaled at roughly the same rate. Agents break the ratio. The author writes faster than the reviewer can read.
