add toolbelt

I want to add a "toolbelt" our agent can use (with reasoning), as well as the ability to dynamically adjust its personality through sentiment analysis.

example:
tools = [ search, retriever, adjust_sentiment, adjust_personality, adjust_tonality, play_games, etc. ]

The issue describes adding a toolbelt with reasoning and dynamic personality adjustment via sentiment analysis to an AI agent. First, examine the existing agent structure in the repository, likely built with LangChain. Look for agent definition files and any existing tool integration patterns. 'Done' means implementing a modular tool system and sentiment analysis pipeline that the agent can use to adjust its behavior.
