## The Hook

gstack is Garry Tan’s own Claude Code setup as an MIT repo: slash-command roles (CEO plan review, eng review, design review, `/review`, `/qa` in a real browser, `/cso` security audit, `/ship`) so a solo builder runs a structured software factory instead of a blank prompt.

## What's Good

MIT (garrytan/gstack, VERSION 1.91.25.0). All Markdown skills plus power tools — README counts 23 specialists and eight power tools. Install: `git clone … ~/.claude/skills/gstack && ./setup` (needs Claude Code, Git, Bun); `./setup --host codex|opencode|cursor|factory|kiro|copilot` for other harnesses (experimental tier). Team mode bootstraps a repo so teammates get it. Telemetry is opt-in and every off-machine send writes a local receipt (`gstack-egress list`). ★~135k.

## The Catch

Blast radius: browser skills drive your real logged-in sessions (Aside on macOS) or import cookies from Chrome/Brave/Arc into its bundled browser — treat `/setup-browser-cookies` and the sidebar agent like handing over your accounts. 135k stars in ~7 months — rank on the workflows, not the counter. Claude Code is the only “full” tier; other hosts are advisory, and outside reviews expect Codex/Claude CLIs signed in. Team mode auto-updates every session (throttled hourly) — pin if you need reproducible agents. Vs mattpocock-skills / agent-skills / superpowers: those are smaller composable packs; gstack is a whole opinionated org chart with a browser runtime.

## Verdict

MIT opinionated Claude Code software factory when a solo founder wants plan→review→QA→ship roles out of the box — heavy setup and real-session browser power; pin it and audit what it can log into.
