gstack: Garry Tan turned Claude Code into a 23-role company
Garry Tan, the CEO of Y Combinator, open-sourced his exact Claude Code setup back in March. It's called gstack, and it's back on GitHub's trending page right now with 113,000 stars, one of the most-starred things on all of GitHub. The pitch is simple and a little unhinged: stop using one AI coding assistant, run a whole engineering org made of them.
gstack is 23 opinionated slash commands, each playing a role a real software company has. A CEO that rethinks whether you're even building the right thing. An eng manager that locks the architecture before anyone writes code. A designer that catches AI slop. A reviewer hunting production bugs. A QA lead that opens a real browser and clicks around. A security officer running OWASP and STRIDE audits. A release engineer that ships the PR. The workflow is a sprint: think, plan, build, review, test, ship, reflect. Tan says he runs 10 to 15 of these sprints in parallel, each in its own isolated workspace.
What makes this worth your attention isn't the code, it's who wrote it and what it implies. The guy who funds more startups than anyone on earth is telling you the unit of software is no longer the developer, it's the managed team, and one person can now sit in all the seats. gstack is mostly co-authored by Claude Opus itself, visible right in the commit history. The discipline is the product. The model is a commodity; the org chart you wrap around it is the moat.
It's MIT-licensed and works with Claude Code plus seven other agents including OpenClaw, Codex, and Cursor. Worth saying honestly: this isn't a fresh launch, it shipped March 12 and is just surging on trending again. But it's one of the most influential agent setups that never got its due here, and the idea behind it only gets more true as agents get more capable. github.com/garrytan/gstack
