Most developers using Claude Code are leaving 80% of its potential on the table. They ask it to write a function, copy the result and move on - one prompt, one response, one task at a time - and wonder why they're still doing most of the work themselves while other people are shipping products twice as fast.
There's a free repository that changes this completely. It gives Claude Code 23 structured skills that handle the work most developers still do manually - product thinking, architecture, design, QA, documentation. Developers who use it report saving 3-5 hours a day on routine work and shipping products in days that used to take weeks.
An 18-year-old student from Bishkek used it to win the Cursor Hackathon - building a fully working game in 2 hours while 80 other participants were still figuring out what to build. The repository is free, the install takes three commands and 108,000 developers have already found it while most people reading this haven't.

The repository most developers haven't found
The repository is called gstack and it was built by Garry Tan - president of Y Combinator. He didn't publish a tutorial or a blog post. He published his actual personal Claude Code setup as open source for anyone to use for free.
The core idea is in one sentence from the README:
"Same person. Different era. The difference is the tooling."
Most developers open Claude Code and treat it like a smart autocomplete. gstack turns it into a complete development system where product thinking, engineering decisions, design, testing and documentation all happen through structured workflows that pass results between phases automatically - so you're not re-explaining context at every step.

What the 23 skills actually do
gstack organizes work around phases every product goes through whether you acknowledge them or not:
Think → Plan → Build → Review → Test → Ship → Reflect
Each skill handles one phase and passes its output to the next so the work flows without you restarting the context every time. The skills that save the most time:
1/office-hours2YC-style review before you write a single line of code.3Asks 6 forcing questions. Pushes back on your problem framing.4Saves you from spending weeks building the wrong thing.56/plan-ceo-review7Finds the 10-star version of your idea.8Identifies what to cut to reach the narrowest real MVP.9Turns a vague concept into a decision you can act on today.1011/plan-eng-review12Full architecture from a product decision.13Database schema, API design, edge cases, failure modes, security.14The technical plan that used to take a senior engineer half a day.1516/design-shotgun17Generates 4-6 design variants simultaneously.18Opens a visual comparison in your browser.19Learns your taste across sessions.2021/design-html22Converts an approved design to production HTML and CSS.23Detects your framework automatically - React, Svelte, Vue.2425/qa26Opens a real browser and clicks through your actual flows.27Finds bugs in the running product not just in the code.28Fixes them and writes regression tests so they don't come back.2930/ship31Checks everything before anything goes out.32Calls /document-release automatically every time.3334/document-release35Updates README, ARCHITECTURE, CONTRIBUTING, CLAUDE.md36after every change so documentation never falls behind.
The skill most people skip
/office-hours is the one most developers ignore because it feels like it slows you down before you've started building. It doesn't - it's the session that tells you whether you should be building what you're planning to build at all before you spend three weeks on the wrong thing.
It asks 6 forcing questions, pushes back on your assumptions and generates 3 alternative approaches you probably haven't considered. For Rakhatbek at the hackathon this compressed the 30 minutes most teams spend debating what to build into 5 minutes of structured thinking that gave his team a clear direction before anyone else had started.
GBrain: memory that survives session ends
Every serious Claude Code user eventually hits the same wall - the session ends and the agent forgets everything. You re-explain the codebase tomorrow, re-explain the decisions that were already made and start from zero every single time.
gstack includes GBrain which gives the agent persistent memory between sessions. You control exactly what it can access through three trust levels - read-write for full access, read-only for analysis without changes, or deny for anything you want to protect completely. The project stays exactly the way you left it.
How to install it
1git clone --single-branch --depth 1 \2 https://github.com/garrytan/gstack.git \3 ~/.claude/skills/gstack45cd ~/.claude/skills/gstack67./setup
Then add this to your CLAUDE.md so Claude Code knows the skills exist:
1## gstack2Use /browse from gstack for all web browsing.34Available skills:5/office-hours, /plan-ceo-review, /plan-eng-review,6/design-shotgun, /design-html, /review, /ship,7/qa, /document-release, /autoplan, /pair-agent
For teams there's a single command that makes gstack part of the repository so everyone works with the same process - which means the same quality bar, the same review process and the same documentation standards across every person touching the codebase.
The proof it works
Rakhatbek Zholdoshkanov is 18 years old and studies Computer Science at San Francisco State University. He flew back to Bishkek for the Cursor Hackathon and won it as team lead - but the story of what he actually built in those 2 hours is what makes it impressive.
The project was called Pixel Bishkek - a pixel-art map of the city with interactive locations, mini-games and multiplayer built in. Players compete against each other in real time with minimal latency. The game includes a karaoke mini-game where the camera recognizes hand movements through computer vision, akok-boru competition mode and interactive scenarios across locations like Yntymak Park. Everything from image generation to the pixel art style was done with AI tools.
Rakhatbek handled about 90% of the technical development himself as team lead. His verdict on what made it possible: "Without AI tools it would have been practically impossible to build a game like this in 1 hour 45 minutes manually."
The stack was Cursor, Supabase and Vercel - and gstack's /office-hours skill specifically helped translate raw ideas into concrete features during the first minutes when most teams were still debating direction. The jury was most impressed by the visual style, the multiplayer and the computer vision elements. The project went live the same day and anyone can play it right now.
81 participants. 27 teams. One team had a system that compressed product thinking into minutes instead of losing the first hour to debate.
