-"""Interactive command line client for the RAG agent.
+"""CLI entry point for the RAG agent.
 
-Commands:
-  /add <title> <path>   – Load a document from a file and add it to the knowledge base.
-  /search <query>       – Search the knowledge base and display results.
-  /quit                 – Exit the program.
-  /help                 – Show this help message.

-The client uses the global agent defined in ``src.agent`` and the knowledge
-base instance from ``src.tools``.
+This module provides a :func:`run_cli` function that loads documents from a
+directory into the knowledge base and then starts an interactive chat loop.
