Show HN: YC Advisor – AI grounded in 434 YC essays, interviews, and lectures

I wanted startup advice that was actually grounded in real YC content, not generic ChatGPT responses. So I scraped and transcribed the YC Library and built an AI advisor on top of it.

What's in there: - Paul Graham's essays - YC founder interviews - Startup School lectures - Various YC partner talks

434 resources total, all indexed and searchable as a skill via natural language.

The skill is open source: https://github.com/Agent-3-7/agent37-skills-collection

Built as a Claude Skill on Agent37 (a platform marketplace for hosting AI skills).
