npx foundry-design installRestart your agent, then open a project.
Restart your selected coding agent once so it loads the shared connection. Open the project you want to refine and ask your agent:
Start Foundry for this project and keep listening for Apply with agent requests.The agent starts Foundry from the project, adds or updates its supported development adapter, validates the integration, and opens the visual session. Keep the agent listening while you work.
Make one change, then review it.
Select an element on the canvas or in Layers. Change a value in the Inspector, then open Review to inspect the original and requested values. These are temporary visual edits until you approve the batch and choose Apply with agent.
