When to use it

You are a solo builder who wants Claude Code to act as a full engineering team (CEO, architect, designer, QA lead, security officer)
You want a repeatable sprint process: think, plan, build, review, test, ship, reflect, instead of ad-hoc prompting
You need structured planning reviews (product scope, architecture, design audit) before writing code
You want browser-based QA against a live/staging URL plus automated PR creation and deployment

Commands & flags

/office-hours <idea>: Reframe and interrogate the idea before planning.
/autoplan: Run CEO, engineering, and design planning reviews together.
/review: Staff-engineer bug hunt over the implementation.
/qa <staging-url>: Real-browser QA against a live or staging URL.
/ship: Open a pull request for the change.
/land-and-deploy: Merge and deploy the shipped PR.
/cso: Run a security audit of the change.

How to use it

After cloning into ~/.claude/skills/gstack and running ./setup, add a gstack section to your project's CLAUDE.md, then drive a feature through the sprint by chaining slash commands.

git clone --depth 1 https://github.com/garrytan/gstack.git ~/.claude/skills/gstack && cd ~/.claude/skills/gstack && ./setup

Typical loop inside Claude Code: /office-hours (reframe the idea) -> /plan-ceo-review + /plan-eng-review + /plan-design-review (or /autoplan) -> implement -> /review (staff-engineer bug hunt) -> /qa <staging-url> (real-browser testing) -> /ship (open PR) -> /land-and-deploy. Extras: /cso (security audit), /design-shotgun, /browse, /pair-agent, iOS QA, and safety commands /careful, /freeze, /guard. Requires Bun v1.0+.

Why it earns its place

gstack packages an entire AI engineering team into one installable skill collection, replacing scattered prompts with a disciplined sprint pipeline where each role's output feeds the next stage. It covers the full lifecycle most individual skills don't — from product interrogation and multi-angle planning reviews through real-browser QA, security audits, and automated shipping.
