Send this message:Build a text-to-image workflow for a red sneaker on a neutral gray background. Use an available model and include a Save Image node. Check the workflow for errors, but don’t run it yet.The Agent builds the workflow on the canvas, fills in the prompt and model settings, and checks the node connections and required inputs. You should see a connected workflow ending in a Save Image node. If the Agent reports a missing model or file, supply it or ask for an alternative available in your installation. Ask it to check the workflow again before continuing.
Generate the image
Open Run permissions next to the message box, choose Ask before a workflow runs, and select Save changes if you changed the setting. Send “Run this workflow.” When the Agent asks for approval, select Run. Select Cancel instead if you do not want to start that run. When generation finishes, the Agent returns the output in the conversation. The image also appears in the Save Image node. Right-click the image there to save it to your computer.Make a change
Send “Change the background to white and keep the model and other settings.” The Agent updates the existing workflow. Ask it to run again to compare the result.Troubleshooting
