Claude Code creator Boris Cherny on traits of side projects that take off > Start with automation — it's free leverage. Engineers build it faster than anyone, yet most underuse this superpower. Ask yourself: 'How can I do less of my work? >Track recurring problems & Automate until there's... nothing left. Boris once tracked every code review comment in a spreadsheet and turned repeated issues into lint rules which eventually became a flock of lint rules. >Your problems are a signal. Build for yourself first — a YC principle. He'd validate an idea, ping a few engineers, let it grow. One of his side projects hit 50-100 engineers at Meta. >Stay in the code. Intuition fades fast when you're not coding. The best ideas come from being anchored to reality. >Side quests = leverage for everyone. His projects improved prod and dev infra. What slowed him down slowed his whole team. Fixing them created leverage beyond himself.show more

The person who built Claude Code just explained how he is using it "Now I just have an army of agents that are doing stuff" Only 18 minutes, the best Claude guide on the internet right now. Boris Cherny covered: > how Claude Code is moving beyond just engineers > routines for CI, code review, and daily workflows > why the loop is the next big leap > working with hundreds of agents at once everything is already running through agents, ignoring this is not an option that's exactly why I wrote a full guide on how to build one yourself with Claude Code article below

Boris Cherny (creator of Claude Code, Anthropic): "My entire CLAUDE.md is two lines. With every new model you need less instruction, not more, most people are over-engineering the one thing that should stay tiny." in a 7-minute interview, Boris Cherny breaks down why the smallest AI-coding setup wins, and the one moment you should delete your config and start from scratch most engineers do the opposite: they pile on rules, build scaffolding around the model… then the next model ships and makes all of it useless. what he actually keeps in those two lines, and why he tells his team to throw the rest away. Watch the talk, then read the article below. That’s worth more than a $800 course on agent engineering.

Creator of Claude Code: "100% of our pull requests at Anrtopic are run by Claude Code. 80-90% of code review too. The feature I’m using the most for my agents is /loops. I’m not prompting Claude anymore - I’m building loops" in 1-hour podcast, Boris shows his setup, which helps him build the #1 coding tool of this year. Worth more than a $500 vibe-coding course.

What does it mean for software engineering when we no longer write the code? Here's the take from Boris Cherny (Boris Cherny), the creator of Claude Code. Timestamps: 00:00 Intro 11:15 Lessons from Meta 19:46 Joining Anthropic 23:08 The origins of Claude Code 32:55 Boris's Claude Code workflow 36:27 Parallel agents 40:25 Code reviews 47:18 Claude Code's architecture 52:38 Permissions and sandboxing 55:05 Engineering culture at Anthropic 1:05:15 Claude Cowork 1:12:48 Observability and privacy 1:14:45 Agent swarms 1:21:16 LLMs and the printing press analogy 1:30:16 Standout engineer archetypes 1:32:12 What skills still matter for engineers 1:35:24 Book recommendations Brought to you by: • Statsig — ⁠ The unified platform for flags, analytics, experiments, and more. • Sonar – The makers of SonarQube, the industry standard for automated code review. Proactively find and fix issues in real-time with the SonarQube MCP Server: • WorkOS – Everything you need to make your app enterprise ready. Three interesting things from this conversation: 1. Boris automated himself out of code review well before AI. Boris was one of the most prolific code reviewers at Meta company. And he worked hard to minimize time spent on code review. His system::every time he left the same kind of review comment, he logged it in a spreadsheet. Once a pattern hit 3-4 occurrences, he’d write a lint rule to automate it away! 2. PRDs are dead on the Claude Code team: prototypes replaced them. Instead of writing Product Requirement Documents (specs), they build hundreds of working prototypes before shipping a feature. Boris: “There’s just no way we could have shipped this if we started with static mocks and Figma or if we started with a PRD.” 3. This is the year of the generalist (and maybe the year of those with ADHD) Boris’s work has shifted from deep-focus single-threaded coding to managing multiple parallel agents and context-switching rapidly. As Boris put it: “It’s not so much about deep work, it’s about how good I am at context switching and jumping across multiple different contexts very quickly.”

Boris Cherny (Creator of Claude Code): "The one technical book I would recommend to everyone that has had the greatest impact on me as an engineer is functional programming in Scala. You're probably never going to use Scala day today, but the way it teaches you to think about coding problems is just such a change from the way that most people were in coding, either practically or in school. It's just. It's incredible. It's going to completely change the way that you code now. I think in types, when I code, the thing that matters in your code the most is the type signatures. This is more important than the code itself." Boris Cherny

AI can’t yet one-shot an entire product—but with the rise of vibe coding, supercharged developers are getting close. Part intuition and experimentation, part validation, it's the new frontier of software development. YC's Tom Blomfield (Tom Blomfield) has spent the last month building side projects with tools like Claude Code, Windsurf, and Aqua, seeing just how far you can push modern LLMs. From writing full-stack apps to debugging with a single copy paste of an error message, AI is becoming a legit collaborator in the dev process. With tips from YC founders in the Spring batch, this is a playbook for anyone who wants to get the most out of vibe coding and build faster.

"The one thing that's going to be truly future proof is judgment. What is the biggest challenge when you have a thousand AI engineers writing code? AI slop. In an era when you can do everything, the question is which of these things matter. On the engineer side, it is evaluating the code. Which of this code is even valuable? You can have AI engineers writing beautiful code that could be wrong, that could have bugs in it, that could be vulnerable. Someone needs to review it. Make sure to have a human review at some point, especially critical code that is in the core of your system. On the product side is judgment around what needs to be built and evaluating. And similarly in design, you have to have judgment around, does it make sense in the broader design system. I think this judgment is the number one thing that humans are going to bring in an era of infinite productivity."

"Not a single one of our full-time engineers right now writes code anymore... it's all agentic... the way you build a company completely changes." JD Ross with Joe Lonsdale on the future of software: JD Ross: Not a single one of our full-time engineers right now writes code anymore. They do everything through Codex, Claude Code, or Cursor. Joe Lonsdale: It's all agentic. JD: It's all agentic. Joe: A lot of them are managing lots of agents at once, right? That's how they're working? JD: Yeah, Cole who runs our engineering team has six agents that are running at once at all times just doing different kind of projects. When we create a new ticket in Linear, it automatically kicks off this thing that basically creates a dev environment, which then tries to one shot the solution and then creates a PR that we review. The whole way you build software is changing so quickly. And I think right now the cost of software is just asymptotically dropping to zero... which means that the way you build a company completely changes. We can now have an enterprise customer come up who says, "Oh yeah, this is so close. What we actually need it for is X." We can build X in one day, ship it live, and close that deal. We did this last week... It's a completely different way of even thinking.
