About This Guide

This guide explains why standard RAG fails on code (vocabulary mismatch, fixed-size chunking, missing multi-hop context), then walks through the full production architecture: query processing, semantic + keyword + graph traversal retrieval, context assembly with token budgeting, and generation. Includes complete Python implementation examples and a production checklist.
