Run a /grilling session, using the /prototype skill — each question is asked with prototypes, not words:

Each round, build 5 radically different prototypes of the current design question into one live mocked app: one standalone HTML file (Artifact tool), updated in place each round.
A floating bottom-right draggable picker names each design; ←/→ arrows switch between them, restyling the mocked app live. When the design has meaningful states (an inbox: full vs empty), add picker buttons that toggle the mock between them.
The grilling walks down the visual design tree, each verdict zooming in one level: the overall design, then component groups, then individual components — until the user has designed the entire feature in detail.
