gstack — Garry Tan’s Claude Code Setup

Turn Claude Code into a full virtual engineering team — CEO, designer, reviewer, QA, and release. (For developers.)

gstack is entrepreneur Garry Tan’s exact Claude Code setup, packaged as one system: 23 opinionated specialists and 8 power tools that turn Claude Code into a virtual engineering team — a CEO, an engineering manager, a designer, a code reviewer, a QA lead, a security officer, and a release engineer. All slash commands, all Markdown, MIT-licensed and free.

What it does

Turns Claude Code into a virtual engineering team of specialists — each one a slash command.
A CEO that rethinks the product, an engineering manager that locks the architecture, and a designer that catches “AI slop.”
A reviewer that hunts production bugs, a QA lead that opens a real browser, and a security officer that runs OWASP + STRIDE audits.
A release engineer that ships the PR — plus power tools for planning, benchmarking, and browsing.
