“我觉得自去年十二月以来，我几乎没打过一行代码，这变化非常大。”——安德烈·卡帕西，《无前科》播客，2026年3月

当我听到Karpathy这么说时，我很想知道是怎么做到的。一个人如何像二十人团队那样完成任务？Peter Steinberger基本上是用AI代理独自一人打造了OpenClaw——247K的GitHub明星。革命已经来临。一个拥有合适工具的开发者可以比传统团队更快行动。

我是Garry Tan，Y Combinator的总裁兼首席执行官。我曾与成千上万的初创公司合作过——Coinbase、Instacart、Rippling——那时他们还只是车库里的一两个人。在加入YC之前，我是Palantir最早的工程师/项目经理/设计师之一，共同创办了Posterous（后来卖给了Twitter），并创建了YC内部社交网络Bookface。

gstack 是我的答案。 我做产品已经二十年了，现在出货量比以往任何时候都多。过去60天：3个生产服务，40+已发布功能，兼职，同时全职运行YC。关于逻辑代码变更——不是AI会膨胀的原始LOC——我2026年的运行速度是**~810×是2013年的速度**（11,417 对比 14 行逻辑/天）。

gstack

gstack turns Claude Code (and other coding agents) into a virtual engineering team: a CEO who rethinks the product, an eng manager who locks architecture, a designer who catches AI slop, a reviewer who finds production bugs, a QA lead who opens a real browser, a security officer who runs OWASP + STRIDE audits, and a release engineer who ships the PR. All slash commands, all Markdown, all free, MIT license.

I’m Garry Tan, President & CEO of Y Combinator. This is the open source software factory I use every day, and I’m sharing it because these tools should be available to everyone. The story, the productivity numbers and how I run ten sprints at once are in Why gstack.

Fork it. Improve it. Make it yours. And if you want to hate on free open source software — you’re welcome to, but I’d rather you just try it first.

Who this is for:

• Founders and CEOs — especially technical ones who still want to ship
• First-time Claude Code users — structured roles instead of a blank prompt
• Tech leads and staff engineers — rigorous review, QA, and release automation on every PR

Quick start

1. Install gstack (two pastes, about 30 seconds of setup; see below).
2. Run /office-hours and describe what you’re building. It pushes back on your framing and writes a design doc the other skills read.
3. Run /review on any branch with changes. It finds the bugs that pass CI but break in production, and fixes the obvious ones.
4. Run /qa on your staging URL, or on an isolated local API, CLI, job or webhook. It opens a real browser, reproduces bugs and fixes them.

Stop there. You’ll know if this is for you. When you want the whole sprint, /autoplan reviews a plan end to end and /ship runs tests, review and the PR.

Install — about 30 seconds

Requirements: Claude Code, Git, Bun v1.4.2+ (the tested version; setup refuses Bun older than 1.3.3, which would let compiled tools read a project’s .env), and Node.js on Windows. Recommended on macOS: the Aside browser (macOS 15+), which the browser skills, /make-pdf and /diagram drive first with your real logged-in sessions; without it, ./setup builds gstack’s own bundled browser. /cso needs a native toolchain as well; setup says so and leaves it unavailable when the toolchain is absent. Timing, the /cso prerequisites and the hooks setup registers: docs/install.md.

Step 1: Install on your machine

Open Claude Code and paste this. Claude does the rest.
