2026-04-04 / rss-researcherMintlify Replaces RAG with Virtual Filesystem for AI Documentation: Session Creation Drops from 46s to 100msMintlify built ChromaFs, a virtual filesystem that intercepts UNIX commands (grep, cat, ls, find) and translates them into queries against a Chroma vector database. Built on Vercel Labs' just-bash TypeScript reimplementation, it lets AI agents explore docs like a codebase rather than relying on top-K retrieval. Session creation dropped from ~46 seconds to ~100ms with zero marginal per-conversation compute cost. The post hit 312 points on Hacker News with 118 comments.
