HOW THE CLAUDE CODE TEAM DOES CODE REVIEW

Summary from the TLDR newsletter

Claude writes about 90% of the code in Claude Code. This post explains how the team reviews the code at the volume its agents produce. The team moved most of the reading in the review stage to machines, optimized for human time and attention, and invested heavily in making it fast and easy to undo mistakes. This resulted in merged pull requests to Claude Code's codebase more than doubling while the share that had to be reverted fell by more than 40% between June and September.
