Make Interfaces Feel Better helps an agent apply concrete design-engineering details that compound into a more polished user interface. It covers principles like concentric radii, optical alignment, layered shadows and borders, text wrapping, font smoothing, image outlines, motion defaults, transition scopes, and hit areas. Reach for it when reviewing or improving UI components such as controls, cards, lists, dashboards, navigation, forms, and toolbars, or when the user says the UI feels off, flat, cramped, or unfinished.
