Use Garry Tan's exact Claude Code setup: 23 opinionated tools that serve as CEO, Designer, Eng Manager, Release Manager, Doc Engineer, and QA
GStack is Garry Tan's comprehensive skill library for Claude Code that transforms the AI assistant into a virtual engineering team with 23 specialized roles—CEO, designer, engineering manager, QA lead, security officer, and release engineer. Each skill operates as a slash command covering the full development sprint: product planning (/office-hours, /plan-ceo-review), architecture review (/plan-eng-review), design iteration (/design-shotgun, /design-html), code review (/review), testing (/qa), security audits (/cso), and deployment (/ship, /land-and-deploy). Skills chain together with shared context—design docs from planning feed into reviews, test plans guide QA, and nothing falls through the cracks across parallel sprints.
Key Features
Use Cases
- 01Running 10-15 parallel development sprints with Conductor, each using different gstack skills for planning, implementation, review, and deployment
- 02Converting vague product ideas into validated specifications through /office-hours forcing questions and /plan-ceo-review strategic challenges
- 03Generating multiple design mockup variants with /design-shotgun, collecting feedback, then converting approved designs to shippable HTML
- 04Automated end-to-end QA testing with /qa that opens real browsers, finds bugs, fixes them with atomic commits, and generates regression tests
- 05Running comprehensive security audits with /cso for static and runtime vulnerability scanning with repair candidates
- 06Coordinating multiple AI agents (Claude Code + OpenClaw + Codex) on the same project through /pair-agent browser sharing

gstack — FAQ
What is GStack and what does it do?+
GStack is a library of 23+ specialized skills (slash commands) for Claude Code that turn the AI assistant into a virtual engineering team covering product planning, design, code review, testing, security audits, and deployment. Skills chain together—design docs from /office-hours feed into /plan-ceo-review and /review—creating a structured sprint workflow from idea to production.
How do I install GStack for Claude Code?+
Clone the repository to ~/.claude/skills/gstack and run ./setup: git clone --single-branch --depth 1 https://github.com/garrytan/gstack.git ~/.claude/skills/gstack && cd ~/.claude/skills/gstack && ./setup. The setup script detects your platform, installs dependencies (Bun, Node.js, Chromium), and registers all skills. Add a gstack section to your project's CLAUDE.md listing the available skills.
Which AI coding assistants work with GStack?+
GStack supports Claude Code (primary), OpenAI Codex CLI, OpenClaw, Cursor, OpenCode, Kiro, Slate, Factory Droid, and Hermes through automatic host detection during setup. Run ./setup --host <name> to target a specific agent, or use the instruction-only digest for any rules-reading agent like Zed, Amp, or Jules.
What are the prerequisites and do I need API keys?+
Requires Git, Bun v1.0+, and Node.js (Windows only). Optional: Aside browser (macOS 15+) for authenticated browser automation; otherwise uses bundled Chromium. Anthropic API key for Claude Code; OpenAI key for /codex second opinions; Supabase URL for GBrain persistent memory. All API keys are optional depending on which features you use.
Is GStack free and open source?+
Yes, GStack is completely free under the MIT license with no premium tier or waitlist. All 23 skills, browser automation, security tools, and documentation features are included. Opt-in anonymous telemetry can be disabled with gstack-config set telemetry off.
How does the browser automation work?+
GStack drives the Aside browser first on macOS (your real logged-in sessions in agent-controlled tabs), falling back to bundled headless Chromium on other platforms or when Aside isn't running. Skills like /qa, /browse, /scrape, and /design-review open browsers, navigate pages, take screenshots, and extract data. /open-gstack-browser launches a headed AI-controlled Chrome with sidebar agent for manual tasks.
