Handles Android UI/UX design and reviews using Material 3 Expressive, Google's flavor of Material You with bolder shapes, richer color, and controlled motion. It's built for component token lookups (buttons, dialogs, sheets, toolbars) and will give you guidance plus token references by default, not just implementation snippets. The intake questions cover device class, window size, and hero moments, which is smart because M3 Expressive lives or dies on restraint. It enforces max 1-2 hero moments per flow and won't let you strip text labels for aesthetics. The tiered reference system loads an index first, then pulls component specs on demand. Good for design decisions, not useful if you just want boilerplate code without thinking through hierarchy or accessibility.
