@garrytan Thanks for applying @garrytan - unfortunately GStack wasn't selected for DancinDaytonaCombinator at this time. We review a lot of applications and can't provide feedback on specifics, other than we'd like you to keep applying.

@garrytan Crazy that you guys are really making a video about this. I guess he is your CEO, but this seems pretty elementary for a company like Ycom

@garrytan been running skills and subagents for about 3 weeks in claude code. the big unlock wasn't the individual skills, it was the subagent picking which skill to load so context doesn't blow up on a 400 line task. single prompt runs doing what used to take 4-5 rounds.

@garrytan GStack is to software development what Tumblr blogs were to fine literature. Except that it will never get anywhere near the five minutes of relevance that Tumblr did.

@garrytan This is hilarious. I built my own gstack in a day personalized to my own workflow… it’s a helper tool… Using YC channel to promote this is just pure comedy
