## Takeaways

1. TypeScript and React were a good fit for earlier models.
2. He says he ships dozens of PRs a day, sometimes 150.
3. Loops can repeatedly handle tasks like fixing CI and monitoring feedback.

## About this segment

Boris Cherny says the model writes all his code, and shares how he coordinates agents and recurring loops. His workflow shows what agent-first software development looks like in practice.

## Transcript

Transcribed by machine (Whisper) from the episode’s audio, so a word may be off here and there.

[5:08](https://realalpha.app/v/SlGRN8jh2RI/?t=308) So you've said on the record that you think coding is solved. If this is one of the three bets for Anthropic, can you tell us more about what you mean by that and what might still not be solved or what secondary problems might come? All right, I can ask another question for the room. Who writes 100% of their code by hand? Who writes 100% of their code using an agent, like quad code? Okay, who's like somewhere in between?

[5:35](https://realalpha.app/v/SlGRN8jh2RI/?t=335) Okay, so like 50% solved. I mean, for me, it's like, for me, it's 100%. Like the quad code code base, you know, it leaked, so, you know, people know. It's pretty simple. It's just like TypeScript and it's React. Like, there's no big secret. There's nothing really complicated. The reason we picked TypeScript and React is it's very on distribution for the model. So when we started, you know, building the code base, the model was not as intelligent as it is today.

[6:01](https://realalpha.app/v/SlGRN8jh2RI/?t=361) So the language and the framework mattered a lot. Nowadays, you know, it can write whatever and it can pick up new languages, new frameworks. It hasn't seen. But back then you wanted to do something pretty on distribution. Because of that, I think fairly early, we got to the point where the model just wrote 100% of the code. And for us, this happened sometime in October, November, or last year. And so for me today, you know, like the model writes 100% of my code.

[6:25](https://realalpha.app/v/SlGRN8jh2RI/?t=385) I write somewhere, you know, usually a few dozen PRs every day. There was a day last week I did like 150 PRs in a day. That was a record. I was just trying to kind of push to see how far I can get it. But yeah, it's like for me, it's just solved. But this is not the case everywhere. There's very big complicated code bases. There's kind of weird languages the model's not good at yet. And, you know, as everyone here knows, it's getting there.

[6:47](https://realalpha.app/v/SlGRN8jh2RI/?t=407) Usually the answer is just wait for the next model. Can you actually tell us about your personal setup? You walked us through it the other day. It is pretty wild. Yeah. So I shared my personal setup like six months ago or something on Twitter. And it's funny. I actually, I shared it. I didn't realize that it would be surprising for anyone. That was just like the way that I coded. And it's changed since then.

[7:09](https://realalpha.app/v/SlGRN8jh2RI/?t=429) It's changed. And so now actually most of my work I do for my phone. And so I don't know if like you guys won't be able to see this, But I have, so I have like the Claude app and if you open the Claude app, on the left hand side there's this little code tab and I just have a bunch of sessions going. You probably can't see it. How many sessions? Usually I have like maybe like five to ten sessions. And then the sessions usually have a bunch of agents.

[7:39](https://realalpha.app/v/SlGRN8jh2RI/?t=459) So I think currently probably like a few hundred agents going. Usually every night I have like a few thousand that are doing kind of deeper work. There's a few ways to manage it. One is that you ask Claude to use a bunch of subagents to do work. Actually, the thing that I've been finding myself using more and more is loop. So this is slash loop. and it's just like the coolest thing. It's like the simplest thing that works.

[8:02](https://realalpha.app/v/SlGRN8jh2RI/?t=482) All it is is you have Claude use Cron to schedule a job for some point in the future and it's a repeat job. And it can run every minute, every five minutes, every day, kind of however often you want to schedule it. And at this point I have like dozens of loops that are running for stuff. So I have one that's babysitting my PRs, like fixing CI, auto rebasing. I have another one that keeps CI healthy.

[8:24](https://realalpha.app/v/SlGRN8jh2RI/?t=504) So like if there's like a flaky test or whatever, it'll go and fix it. I have another one that grabs feedback from Twitter and kind of clusters it for me every 30 minutes. So I just have a bunch of these loops running at any time. I sort of feel like loops are the future at this point. If you haven't experimented with it, highly, highly recommend it. And we also just launched routines,
