Claude Code + LightRAG = UNSTOPPABLE

Graph RAG is presented as the modern replacement for naive RAG when dealing with large document corpora (500–2,000+ pages). LightRAG, an open-source graph RAG library, is shown as a cost-effective alternative to Microsoft's GraphRAG. The tutorial covers RAG fundamentals (chunking, embeddings, vector databases), how graph RAG adds a knowledge graph layer for richer relational queries, and how to set up LightRAG via Docker and Claude Code. It also demonstrates connecting LightRAG to Claude Code using API-based skills for querying, uploading, and exploring documents without using the web UI directly.
