## What it is

Garry Tan's open source toolkit of slash commands that work as specialist roles: product review, design, architecture, QA, security and release.

## What it’s for

Use it to run a Think, Plan, Build, Review, Test, Ship and Reflect cycle inside Claude Code.

## Benefits

- QA with a real browser and a team mode that updates gstack automatically
- Main support for Claude Code and partial support for Codex CLI, Cursor and Gemini CLI

## Caveats

- MIT license, free, no paid version
- Requires Claude Code, Git and Bun 1.4.2 or later
