+## Define the Agent Using the Agent Editor {#define-agent-editor}
+
+The main approach to create and manage agents makes use of the [Agent Editor](https://marketplace.mendix.com/link/component/257918) in Studio Pro. This extension allows you to define, manage and deploy agents as part of your app model. With the extension you can define Agents as documents of type "Agent" in your app while working in Studio Pro, alongside related documents such as Large Language Models, Knowledge bases and Consumed MCP services.

+The Agent Editor will become available shortly after the Mendix Studio Pro 11.9 release as a downloadable extension on the Mendix Marketplace. Click 'Add to Saved' on the [Marketplace listing](https://marketplace.mendix.com/link/component/257918) and stay tuned for updates!

 ## Define the Agent Using Agent Commons {#define-agent-commons}
 
-The main approach to set up the agent and build logic to generate responses is based on the logic part of the Agent Commons module. Start by defining an agent with a prompt at runtime, then, through the same UI, add tools, (microflows as functions) and knowledge bases to the agent version.
