Agent response duplicated in email

Hi,  I have created a Copilot Studio Flow which has 3 agents. 2 agents do some research in parallel, I catch the results in 2 different string variables and hand the variables over to a third agent....

Thank you for your response.

The behaviour is independent from having a variable in between or not. Here are some screenshots.

Here is what I do in the agent 3, where I summarize the output of agent 1 and agent 2.

And this screenshot shows the email send node setup.

Any idea what I can change to get it solved?

Thanks again for checking. I appreciate the help!

Hello Spitzinger​, may be checking these would help? And let me know if you've already managed to fix it!

  • For the agent 1 and agent 2 (which are only doing research), is it set as "Don't respond" under "Completion" - I'm not sure what this section is called in the new GitHub Copilot harness but you should be able to it
  • In agent 3, did you consider adding extra instructions like
    • Do not create additional or duplicate answers

 

This  resource might give you some insights too - https://learn.microsoft.com/en-us/answers/questions/5840426/copilot-studio-duplicate-responses-returned 

If you can share a screenshot of the email that shows how the content appears, that would be helpful :)

    Hi sohnash​,

    thanks for checking my flow.

    - Unfortunately I do not find the "Don´T respond"-setting. I do not have "Completion"-section.

    - In Agent 3, I specifically mention that duplicates should be removed

    Later in the email node I add a general text which appears only once.

    The email output looks like the following:

    Any idea?

    Thanks for all your help

      Thanks for sharing the details, Spitzinger​ :). As the general text you've added displays only once, I think this has something to do with merging the responses.

      A few options for you to try

      • Can you display Agent 1 result and Agent 2 result in the email (or as an output message) so you can see what is the content of these two responses? 
      • Instead of using Agent 3 just for the purpose of combining results, are you able to use a "create generative answers" action or another relevant action that's available in the new experience?
      • I wonder if this is related to the new experience (as you are using the new GitHub Copilot harness for this agent).
        • Do you think you could try doing this in the standard harness experience? Here when you create connected agents, you will see a "Don't respond" option under "Completion". I'm also wondering may be this use case doesn't need the GitHub Copilot harness & could work with the standard harness.

        Thank you for your response and suggestions.

        UNfortunately it will not help to combine Agent 1+2 in general, because both responses coming from both agents, are also doubled.

        I tried to build up the flow in the old environment, but here I am not able to test in general because there are missing credits and I am not able to test, which works in the new environment.

        Any other ideas, why all agent responses are doubled?
