Hi,

I need help to pass variables from my master agent to a connected agent. When i add a Connected agent in to a master agent, i see a Inputs section marked as preview as below, however when i pass the values its not being passed in to my connected agent. What is the way i can pass the variables otherwise.

Please let know if any other details needed further here

Hi @CU28081704-2

Can you share both the input configuration of your child parent and the parent passing at the same time.

I'd like to verify the data types that you are supposed to pass in versus what you are passing in.

And from the Child, how are you validating that you do not see them?

Thanks!!

If these suggestions help resolve your issue, Please consider Marking the answer as such and also maybe a like.

Thank you!
Sincerely, Michael Gernaey

hello,

thanks for the interesting question :)

i think there a lot of using "wrong word" wich are confusing, :) (sorry english not my native language, sometime i use wrong word too)

Multi agent concerne two different idea : connected agent and child agent.

Child agent : allow input / output between the parent and the child and you have parameter for it in the child agent. they are created inside the master agent.

Connected agent : are separated agent and don't have any meen of shareing variable since both leave without each other. they are link to the master agent and they are only published agent.

Between child the UI provide you input/outpud inside the editUI of the agent

Between connected agent you need to use other complexe mecanisme like using database or sharepoint list (with MCP or power automate or agent flow) to share data.

What i tend to myself is something between : i ask the agent to format a prompt witht rules to ask question to other agent. in special case i don't let autonomous orchestration to call agent but i use an agent flow to call the other agent and write myself the prompt send to the agent by associating the question and my war and some rewriting by IA
