Passing a value from a Chain Tool to a Tool Agent

[jamesIDT]

Hello,

I am trying to create a chain that recieves a youtube URL from the user, and then calls an API to get the subtitles to that viedo using a video ID. I have created a custom tool to fetch the youtube subtitles:

I am having difficulty having a Chain Tool pass a value from the chat on to a Tool Agent for it to perform a task. If i were passing it to a LLM chain (that was a tool) this is fine because I can specify the incoming value in "Format Prompt Values" (which is unavailable on the Tool Agent) in the Prompt Template.

Is there anyway to do similar for the Tool Agent?
I have checked LangSmith and basically nothing is getting passed through.

Here is the chat flow:
Advanced Youtube Summariser Chatflow.json

Many thanks in adavnce
James
