gstack

A set of ready-made roles and commands that turn Claude Code into a virtual software team.

What it does

gstack is a collection of add-on instructions, called skills, for Claude Code, an AI coding assistant. Each skill is a slash command that gives the AI a specific job, such as product reviewer, engineering manager, designer, code reviewer, QA tester, security officer or release engineer.

You might start with a command that asks questions about what you are building. Then you can have the AI review a feature idea, check code changes for bugs, or test a website in a real browser. Its makers describe it as twenty-three specialists and eight power tools, all written as plain text files.

It is built mainly for Claude Code, but the README says it can also be installed for other AI coding tools, such as OpenAI Codex CLI, Cursor, OpenCode and GitHub Copilot CLI. Teams can set it up so everyone working on a shared project gets it automatically.

Who it's for

Founders, tech leads and engineers who use AI coding assistants and want structured review, testing and release steps. The README also suggests it for people new to Claude Code who want guided roles instead of a blank prompt.

Can I use it without coding?

With some setup. You install it by pasting one setup instruction into Claude Code, but it needs Git and Bun installed and is meant for working on software projects. New to this? Start here.

Can I run it?

Try it

  1. Install Claude Code, Git and Bun on your computer.
  2. Open Claude Code and paste the install instruction from the README so Claude sets up gstack for you.
  3. Run the office-hours command and describe what you are building.
