GStack transforms Claude Code into a structured engineering team with 25 role-based AI skills. Created by Y Combinator President Garry Tan, it assigns Claude specialized personas — CEO for planning, Designer for UX, Engineering Manager for architecture, QA Engineer for testing, and DevOps for deployment. Each role uses slash commands like /office-hours, /review, /qa, /ship, and /land-and-deploy to execute specific development lifecycle tasks.
