Show HN: CacheZero – Karpathy's LLM wiki idea as one NPM install

Karpathy's recent tweet about LLM knowledge bases went viral (17M views). He described a system where you dump raw content into a folder, an LLM compiles it into an interconnected wiki, and you search/query it through Obsidian.

I built the whole pipeline as a single CLI tool:

- Chrome extension to bookmark tweets, articles, YouTube, anything - Hono server + LanceDB for vector search - Claude Code compiles your bookmarks into wiki pages with wikilinks and citations - Browse in Obsidian with graph view - Publish as a static site with Quartz

npm i -g cachezero

Would love feedback on the compile step specifically — the wiki quality depends heavily on the SCHEMA.md prompt and I'm still iterating on it.
