okay i'm just gonna share this..

*that's part of workflow how i automated my solo marketing agency

been using this free repo for a few weeks. ships in hours what used to take days

23 ready skills. product → design → QA → docs

an 18-year-old won a hackathon with this repo last month. in 2 hours

while 80 others were still figuring out what to build (cheat code for planning)

made by @garrytan (president of YC). 108k stars. you probably haven't found it

[ what blew my mind ]:

the setup takes 3 commands.. not 3 days

> 23 structured skills covering every phase: think → plan → build → ship > /office-hours - YC-style review before you write a line of code > /plan-eng-review - full architecture from one product decision > /design-shotgun - 4-6 design variants in parallel, opens in your browser > /qa - opens a real browser and clicks through your flows. finds bugs in the running product > GBrain - persistent memory between sessions. the agent never forgets again

[ how i'm using it ]:

i run a fully automated marketing agency. solo. zero employees

gstack handles a lot of what used to need 5 hires:

> /office-hours scopes client launches in 5 min instead of 30 > /design-shotgun ships 6 landing page variants in one session > /qa catches broken automation flows before clients see them > /document-release keeps client deliverables updated automatically > GBrain remembers every client's voice + history across sessions

what used to eat my mornings now finishes in an hour

[ the part nobody's talking about ]:

most developers using Claude Code are leaving 80% of its potential on the table.. they treat it like autocomplete

gstack treats it like a development system. product thinking, architecture, design, QA, docs - all passed between phases automatically

you stop re-explaining context every step

[ and the craziest part ]:

Rakhatbek (the kid who won) said it would have been "practically impossible to build a game like this in 1 hour 45 minutes manually"

3 commands. 1 markdown file. 23 skills

most developers will never install it.. not because it's hard, but because they think it's just another tutorial

100% FREE, OPEN-SOURCED

@DeRonin_ automating solo agency work with this looks interesting

23 skills for full dev cycle, that's a solid stack

@DeRonin_ That 18 year old won a literal hackathon while we are doomscrolling like we are some sort of tech king 🥲

Invincible@InvincibleEdge

@DeRonin_ 18 with a hackathon win and shipping faster than a whole team

genuinely curious if it scales past solo though

Solomon Omolabi@S_Omolabi

@DeRonin_ The agency angle is where this gets practical. Map the service as a workflow first: brief, research, draft, QA, client review, delivery. Then let AI speed up each step. I’m sharing more beginner-friendly workflow notes, would be good to stay connected.

Hunter Gon@gonlenidefi

@DeRonin_ was curious about the changes number being that high?

which part of your workflow actually improved the most?

Knight@KnightPredict

@DeRonin_ Thanks for sharing, I'll look into it

Robert Youssef@rryssf

@DeRonin_ passing context between phases via markdown file cuts re‑prompting overhead, but relies on consistent schema enforcement

3h28

Chestuits@Chestu_eth

@DeRonin_ This seems like a game changer for small agencies

the idea of automating so many steps with one tool is compelling and it is great that it is open source for everyone to try

Silver@silver_pump

@DeRonin_ the 18 year old winning a hackathon with it is what got me ngl

@DeRonin_ same setup — claude handles the loops, I handle the editorial judgment calls

5h18

Maxxing Battle@MaxxingBattle

@DeRonin_ 18 yr old beating agencies with a free repo hits different when youve been paying for tools that do half of that

ØxBlitz@blitz_writes

@DeRonin_ this is huge damn

I have a question tho

how do I get into this with zero coding and technical knowledge?

any advice blss?

5h17

主任@zhuren1992

@DeRonin_ This is the kind of tool everyone needs to try

Viktor 🧪@viktornfts

@DeRonin_ tried using this for my own agency last week. it definitely works for the boilerplate stuff but the code quality is pretty hit or miss. still, for free it saves me about 4 hours of tedious setup.

worth grabbing before everyone else figures it out.

Psycho@xoxo_psychoo

Kaisedd@kaisedd3

@DeRonin_ wait the key detail is an 18 year old winning with it

makes me feel like im aging in dog years

5h10

Velon@velonxbt

@DeRonin_ ships in hours what used to take days sounds like a sales pitch but also ngl every solo agency founder will see this and think "finally"
