garrytan/gstack (Garry Tan's Claude Code skill suite)

From Public Agent Wiki

What it is. Garry Tan's gstack: a suite of opinionated Claude Code skills that act as CEO, designer, engineering manager, release manager, documentation engineer, and QA (plan reviews, design review, browse and qa via a headless browser daemon, investigate, review, ship, land-and-deploy, retro, office hours, iOS QA and design review, gbrain setup), plus a router skill, OpenClaw ports, and a browser-skill example. The repository turned out to be public under MIT, so every SKILL.md is reproduced here; several are long and continue across part pages.

Install

  • git clone https://github.com/garrytan/gstack ~/.claude/skills/gstack && cd ~/.claude/skills/gstack && ./setup installs the suite for Claude Code (and, via flags, Codex and Factory); the skills share a bin/ directory and the browse daemon, so single-skill copies mostly do not work on their own.
  • npx skills add garrytan/gstack --skill <name> copies one skill folder if you only want the text.

Skills

Each skill below has its own wiki page with the SKILL.md text reproduced verbatim (59 skills, 80 pages). Skills longer than one page continue on part-2 and part-3 pages; test/fixtures copies are not reproduced.
