AI Summary

gstack adds specialized slash commands to Claude Code for distinct expert modes handling product planning, engineering design, code review, automated shipping, web testing, and team retrospectives.

How It Works

1
🔍 Discover gstack

You hear about gstack from a fellow builder who uses an AI coding helper and wants specialist brains for different tasks like planning or testing.

2
📥 Set it up easily

You tell your AI coding helper to grab and prepare gstack with a simple message, and it handles everything in seconds.

3
👑 Rethink your idea as CEO

Type a slash command to switch your helper into founder mode, where it uncovers the amazing product hidden in your basic request.

4
🔧 Build with engineering smarts

Use another command for tech lead mode to map out the perfect structure, diagrams, and safeguards before writing code.

5
🕵️ Spot hidden bugs

Run a review command to have a paranoid expert hunt for sneaky issues that tests miss, like timing glitches or weak spots.

6
🚀 Ship it perfectly

With one ship command, your helper syncs changes, checks everything, and gets your feature ready to go live.

7
👁️ Test like a pro QA

Command your helper to open a browser, click through your app, take pictures, and confirm it all works flawlessly.

✅ Feature lives beautifully

Your polished feature is live, built faster and stronger thanks to switching expert modes on demand.

AI-Generated Review

What is gstack?

gstack is a TypeScript toolkit from Garry Tan's GitHub (garry tan github) that supercharges Claude Code by adding six slash commands: /plan-ceo-review for rethinking features like a founder, /plan-eng-review for architecture diagrams and edge cases, /review for production bug hunts, /ship for one-command Git sync/PRs, /browse for Playwright-powered QA automation on staging sites, and /retro for commit velocity analysis. It solves the "mushy generic AI" problem by letting you summon specialist modes—CEO taste, eng rigor, QA eyes—instead of wrestling one vague assistant through every workflow. Install via Bun on macOS/Linux; it compiles a browser binary and symlinks skills into your Claude setup or repo.

Why is it gaining traction?

Garry Tan (garry tan y combinator president, garry tan x) built it for his own shipping loop, hooking devs with instant 10x-product pivots via /plan-ceo-review and 60-second browser QA via /browse that logs in, clicks flows, screenshots, and checks console—far beyond Claude's blind guessing. Unlike prompt packs, it enforces gears (planning != shipping) with persistent browser state and Git integration, delivering consistent depth without back-and-forth. The gstack app's demo workflow—plan, code, review, ship, test—mirrors real teams, pulling 285 stars fast.

Who should use this?

Solo founders or indie hackers grinding features in Claude Code, needing structured AI for product-market fit checks and QA without manual browser tabs. Eng leads at YC-style startups (garry tan y combinator vibe) shipping weekly who hate inconsistent reviews or tedious releases. Skip if you're not deep in Anthropic's ecosystem or prefer VS Code agents.

Verdict

Grab it if Claude Code is your daily driver—strong docs and demos make setup painless, but 285 stars and 1.0% credibility score flag it as early alpha; test on non-prod first. Solid for Garry Tan sauna-level obsessives pushing AI workflows. (198 words)
