Adding global variables into prompt tool

Hi
 
I was wondering if there is a way to add a global variable into the prompt tool so I can use it as part of my prompt. So I can combine this with the input file from the user.
 
Thanks.

    Hello CU02010950-0,

    There are two main ways to use “global” values in Copilot Studio prompts and combine them with user input, including files:

    1. Global (bot-scope) variables in Copilot Studio

    You can create variables with a global scope across all topics (bot-scope), which can be referenced in Message, Question, Generative answers, and Prompt action (AI Builder) nodes. This is useful for values like customer IDs, default parameters, or configuration flags that should be accessible throughout the agent.

    To set a variable as global (bot-scope):

    1. Create the variable, for example in a Question or Set variable value node.
    2. Go to Variable properties and set the scope to Global / Bot (any topic can access).
    3. The variable will appear with a prefix (e.g., bot.UserEmail) and can be added via the {x} variable picker in any node, including prompts.

    2. Environment variables (Power Platform) for global configuration

    For “global values” that serve as ALM-friendly configuration (like API base URLs, keys, or model names), use Power Platform Environment Variables. Define these in a Solution via the Power Apps Maker portal, then reference them in Copilot Studio topics. This method keeps sensitive data out of the canvas and supports different values for each environment (Dev/UAT/Prod).

    Yes, you can use a global variable in a prompt across the agent.
    To demonstrate your scenario, use a global variable within the prompt. I’ve created two topics:
    1. Initialize
      • Create a global variable named VarLibraryName, Refer to Screenshot 1
    2. PromptDemo
      • Pass the global variable as a Text input to the prompt, Refer to Screenshot 2,3
