One that could answer questions like "How does the authentication system work?" or "Where is the database connection configured?" without hallucinating answers? That's exactly what we're building today. We'll create a Retrieval-Augmented Generation (RAG) system that ingests your code and documentation, then provides accurate, contextual answers based on your actual files.
