When a button looks wrong, pointing at it is easier than describing where it lives. Superset's Design Mode lets you select an element in the browser preview and send a change request to your coding agent.

Select the element you want to change

Open your repository in a Superset workspace, start its development server, and open the URL in a browser pane. Click Design in the browser toolbar, then click the element you want to change.

A prompt card opens beside the selection. Describe one change, choose your agent, and send it to an existing terminal or a new session. For example:

Superset sends the selected element's DOM and computed styles. A cropped screenshot and React component metadata are included when available. You can keep using the CLI agent you already use for the project.

See the Design Mode demonstration for the element picker and prompt card.

Check the result in the preview

Read the agent's diff, reload the preview, and check the button at the screen sizes your app supports. Try its click behavior too. The screenshot gives the agent context; the preview lets you check what it actually changed.

For browser checks you want to delegate, agents can also read and interact with the workspace's browser pane.

Download Superset and try one UI change in a repository you already work on.
