Boris Cherny1/ Introducing Code Review
Source snapshot: 2026-11-09Independent editorial note
When this pattern helps
The practical value is reducing ambiguity before implementation and making the result observable. Turn the expected behavior into checks that can pass or fail; a confident explanation is not a substitute for a reproducible test.
重点不是让提示词更长，而是先消除实现歧义，并把预期结果变成可通过或失败的检查。模型解释得很肯定，不等于测试已经通过。
New in Claude Code: Code Review. A team of agents runs a deep review on every PR.
- Built for Anthropic's own team first — code output per engineer is up 200% this year, and reviews were the bottleneck
- Boris has been using it for a few weeks and found it catches many real bugs he would not have noticed otherwise
- When a PR opens, Claude dispatches a team of agents to hunt for bugs
