The product announcement describes live screenshots and tool-call updates, so the person testing it can follow the agent's actions without first writing an application.
That makes prompt revision an observable process: issue an instruction, inspect the action it produced, then change the wording or model and try again. The Playground connects to the same sandboxes used by Cua's programming libraries, giving developers a place to investigate behavior before building it into a larger workflow.
