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
