-"""
-CLI for interacting with the RAG agent.
-
-This script provides three explicit commands:
-
-* ``/add <text>`` – add a piece of text to the knowledge base.
-* ``/search <query>`` – search the knowledge base and display results.
-* ``/quit`` – exit the program.
-
-Any other input is forwarded to the underlying agent as a normal question.
