Semantic Skill Kit

Semantic Skill Kit is an open-source Node.js toolkit that enables developers to build topic-specific skills for agents by indexing and semantically searching curated Markdown knowledge bases locally. It adapts and generalizes Google's Modern Web Guidance local embedding and retrieval approach with features like incremental rebuilding, document chunking, and exports for LLM-routed skills. Requires Node.js 22+ and runs embedding models locally without cloud APIs.
