The Problem: Code Review Can't Keep Up AI agents now write code 10x faster than humans. OpenAI's Codex team generated over 1M lines of code in 5 months, with 3 engineers merging an average of 3.5 PRs/day each. Anthropic's long-running agents code continuously for 6+ hours. New problem: code review can't keep up. Imagine a factory line running 10x faster, but the quality inspectors are the same headcount. The inspection queue stretches out the door. OpenAI's answer: agent-to-agent review -- AI reviews AI-written code. But "just ask AI to review" doesn't work. You need a control system.
