What does garrytan/gstack do?

Garry Tan's open source software factory for Claude Code, as a set of skills that each play a role: /office-hours to describe what you are building, /plan-ceo-review to rethink a feature, /review to find production bugs on a branch, /qa against a staging URL in a real browser, and OWASP and STRIDE security audits. Setup needs Git and Bun, and a team mode keeps every teammate's copy up to date.

Its default branch holds 65 SKILL.md files.
