Claude Codes New REVIEW.md System, What is it?

So, Claude Code now writes about 90% of its own code, and things are really speeding up at Anthropic. If you're looking at the web app at the moment, the rate of change is really fast. So, something is working. Between June and September, merged pull requests, that's work being done, more than doubled. But,

the key thing here is the code that was being reverted or had previously been going wrong dropped by 40%. So, what the heck is going on at Anthropic? Well, what I've tried to do is piece it together from several different sources over the last couple of days, so you can learn how to move at this pace. And all

So, anyone who's been working with agents realize there's no problem running a hundred different agents on your codebase. The big problem is you get a ton of code showing up, and it has

to get reviewed and checked in some way. Most of the organizations I talk to, their biggest issue is the code review. So, the Claude Code team just published how they review code now, and this is their key line. We didn't remove review, but we did move most of the reading to machines optimized for human time and

attention, and invested heavily in making it fast and easy to undo mistakes. AKA, the blast radius and the recoverability from that blast. So, I'm Rob from Switch Dimension. I'm going to walk you through Anthropic's process layer by layer, and then I'm going to show you where Claude Code's review product fits in. And it isn't actually

where you'd assume. And then I'm going to finish with a quick look at Seon. It's their replacement for Git, which fits into this whole process. So, if you're a practicing developer, I would definitely hang around. We'll also talk about this one pull request that Anthropic had that went through 50 rounds of AI review overnight. Is that
