Garry Tan's gstack

Garry Tan's 23-specialist Claude Code factory — CEO, Designer, QA and more — wired into a sprint from idea to shipped PR.

The Y Combinator president's public Claude Code setup: 23 role specialists and 8 power tools, all slash commands ("CEO review", "Designer", "QA", /cso security audits, ...) wired into a think-plan-build-review-test-ship-reflect sprint. Interesting both as a toolset and as a window into how a non-traditional-engineering executive actually runs coding agents day to day.

What it does

  • A sprint, not a grab bag: /office-hours (YC-style interrogation) writes a design doc that /plan-ceo-review, /plan-eng-review and /plan-design-review then attack; /review auto-fixes what it can, /qa opens a real browser, /ship runs tests and opens the PR
  • QA with eyes: /qa drives a real browser (Aside on macOS, or the bundled headless Chromium that setup builds) against staging URLs, APIs, CLIs, jobs and webhooks, writing failing regressions and re-verifying fixes
  • Team mode: ./setup --team bootstraps a repo so teammates get gstack automatically, with auto-update checks throttled to once per hour
  • Beyond Claude Code: installs for other agents via --host auto, drives OpenClaw sessions over ACP, and scales to 10-15 parallel sprints in Conductor

When to use it

Founders and technical CEOs who want structured roles instead of a blank prompt; first-time Claude Code users who need a process rather than a blank page; tech leads who want review, QA and release automation on every PR. The README's framing is candid: this is Garry Tan's personal factory, used daily at YC and shared as open source.

Getting started

git clone --single-branch --depth 1 https://github.com/garrytan/gstack.git ~/.claude/skills/gstack && cd ~/.claude/skills/gstack && ./setup

About 30 seconds on a fast machine (includes a binary build and a Chromium download). Requires Claude Code, Git and Bun v1.4.2+.

Things to know

Setup writes a CLAUDE.md section that steers web browsing away from Claude's native chrome tools and toward gstack's /browse — read what it changes before accepting. Telemetry is opt-in and off by default; an update check runs regardless (throttled, silent). /cso (the OWASP + STRIDE security officer) needs a specially built Bun plus a native toolchain, and reports "not assessed" without them. MIT.
