Skill UI

This comprehensive guide helps elevate a UI from merely functional to polished, purposeful, and aesthetically coherent with its domain. It dictates pre-coding design choices, such as defining the audience, tone (e.g., minimal, industrial), and purpose. It provides rigorous guidelines on establishing visual hierarchy, typography, color palettes, and interactions, ensuring the final product feels intentional and professional, rather than generic or templated.

Hallmark is a specialized design skill engineered for AI coding assistants. It enforces deep structural variety and aesthetic sophistication, ensuring generated UIs look professionally 'made' rather than generically templated. Users can invoke Hallmark to build new pages (default), audit existing designs for anti-patterns, redesign components while preserving intent, or extract the 'DNA' (structure, archetypes, color) from existing URLs or screenshots for reference.
