gstack
ActiveDescription
Garry Tan's open-source skill pack turning Claude Code into a virtual engineering team of 23 specialist roles for product review, planning, code review, browser QA and security audits.
Key Features
- Virtual engineering team — 23 specialist roles as slash commands covering CEO product review, eng review, design review, code review, QA and security
- End-to-end slash commands — /office-hours, /autoplan, /review, /qa and /ship chain planning, implementation, review and release
- Real-browser QA — /qa opens a real browser, clicks through flows, and finds and fixes bugs
- Security audits — /cso runs OWASP and STRIDE audits and produces a security report
- Multi-agent support — setup auto-detects and installs skills for 10 agents including Claude Code, Codex, OpenCode, Cursor and Kiro
- Team mode — ./setup --team bootstraps the repo so teammates get gstack automatically, with auto-update checks throttled to once per hour
Use Cases
💡 Solo founders replace a blank prompt with structured roles, moving from office hours through plan review to shipping
💡 Tech leads run automated code review, real-browser QA and OWASP plus STRIDE security audits on every PR
💡 Repos on team mode give every member's Claude Code session the same auto-updating skill set
