Hi everyone,

I am building an agent in Copilot Studio that generates a 
professional scope memo using instructions (not a topic). After 
the memo is generated, I want to send it as an email draft in 
Outlook using a Power Automate flow.

The problem:
- The scope memo is generated by the agent via instructions 
  (generative AI response)
- I need to pass this generated text to a Power Automate flow 
  as an input
- But I cannot find a way to store the bot's last AI-generated 
  response in a variable

What I have explored:
- System.LastMessage.Text — this captures the USER's last message 
  (e.g., "yes"), not the bot's response
- System.Activity.Text — same issue, captures user input only
- There does not appear to be a System.LastBotMessage.Text or 
  equivalent variable
- Global variables cannot be set from within instructions 
  (instructions do not support variable assignment)
- Using a Generative Answer node inside a topic to "extract" the 
  memo from conversation history — this returned undefined/empty 
  values

My questions:
1. Is there any system variable or method to capture the bot's 
   last generated response (the AI output) into a variable?
2. Is there a recommended pattern for passing AI-generated content 
   from the instruction layer to a topic or Power Automate flow?
3. Has anyone successfully implemented a "generate content via 
   instructions → send via email" workflow without asking the 
   user to copy-paste the content?

My current workaround is to generate the scope memo inside a topic 
(using Generative Answer node + Adaptive Card for inputs), which 
allows me to save the output to a variable. However, the Generative 
Answer node is unreliable (see my other post about "no information 
found" errors).

Any guidance on best practices for this pattern would be very 
helpful. Thank you!
