Combine two agents into single angent

Hi Team,

I want to combine pandas agent for structured data and conservation chain for unstructured data into single agent.

Am using tool to combine agents, but how can i use conversational agent in tools

script am using:
tools = [

Tool(

name=“structured data”,

func=agent.run,

description=“We are using structured data like table formated”,

),

Tool(

name=“unstructured data”,

func=qa.run, ## Getting errors

description=“Unstructured data from different sources”,

),

]
