Building With AI Agents

"So we have a Codex code review that's catching a lot of mistakes. It's actually caught some pretty interesting configuration mistakes."

"Explaining exactly what you expect and what you're not getting is even more important with AI than with the humans."

"100% of my code is written by Claude Code. I have not edited a single line by hand since November. Every day, I ship 10, 20, 30 pull requests. So, at the moment I have, like, five agents running."

"What's been surprising and really amazing, the non-technical people using AI agents and programming tools to build things, the people that are able to embrace it to optimize for their particular workday and their particular set of tasks are really showing the most impact from these tools."

"But there's a little bit of a writer's block sometimes. So one of my favorite things that I've seen, and I'm even looking at the home page right now, and you can see a random assortment of community submissions. And they have 1,200 forks, and 1,500 forks, and 6,000 forks, and this is every time people saying like, 'Oh, instead of starting from scratch, I'll start from this application that someone else has built and I'm going to prompt it to modify it and make it my own.'"

"AI just don't understand what do you mean when you say, 'You know what I mean?' So you need to be specific. I'm optimizing 100% of my time today on good judgment, clarity, quality, taste."

"In order for you to steer the ship, you have to know the instructions, right? And the best way to learn is by building, but treating these tools almost as technical co-founders and educators, and learning while doing, and religiously reading the agent output."

"Over the holiday break, it feels like the AI coding thing really hit critical mass and the world's best programmers, including Linus Torvalds, for the first time over the holiday break basically said, 'Yeah, AI is now coding better than we can.'"

"Devin is a fully autonomous software engineer that is going to work on tasks end to end, and so there are a lot of great tools for all parts of the stack of the AI code workflow. What Devin does is it is a full asynchronous workflow, and so you can tag Devin on an issue in Slack, you're talking about an issue and you tag Devin, you can tag Devin in Linear, you can have Devin and Devin will make pull requests in your GitHub, and so it's very much built to work with engineering teams as your junior engineer."

"Our whole team is only like 15 engineers a year. We use a ton of Devin when we're building Devin. Most folks on the team are definitely working with up to five Devins at once, and so Devin merges like several hundred pull requests into production in the Devin code bases every month."

"Engineers are becoming tech leads. They're managing fleets and fleets of agents. It literally feels like we're wizards casting all these spells and these spells are kind of like going out and doing things for you."

"There's a team that's actually doing an experiment right now within OpenAI where they are maintaining a 100% Codex-written code base. They run into the exact problems that you're describing. And so usually you're like, 'All right, I'll roll up my sleeves and figure it out.' This team doesn't have that escape hatch."

"It's very difficult for me to catch mistakes. What I'll do is basically /review. This tells Claude to start reviewing its own code, but what's even cooler is I have Codex as well as Cursor open. I will have each of them review the code."

"Zevi shows you how to work with cursor to quickly add your ideas to Linear to explore your idea with AI, how to develop your plan, how to then build the thing, and then have different LLMs review your code and update your documentation, and then use all of this as a learning opportunity to develop your own sense of how things work."

"I'm not sure who he's quoting, but code is just words at the end of the day. So it's just files on your computer. So basically you can be working on the same project and carry it from app to app. And especially now, I can work with multiple models and apps on my project."
