Agentic RAG Chatbot

This repository houses code for an Agentic RAG system, which conducts retrieval-augmented generation (RAG) on uploaded documents. It retrieves relevant documents from AstraDB and evaluates their relevance. If the retrieved documents are deemed relevant, the system generates an appropriate response to the user's request. Otherwise, it prompts the user for additional information.
