Skill UI

Hallmark is a specialized design skill for AI coding assistants, designed to ensure that generated UIs look genuinely crafted, not machine-generated. It combats the 'AI-slop' aesthetic by mandating structural variety. Users can leverage it for fresh greenfield page builds, auditing existing designs against anti-patterns, redesigning visuals while preserving component architecture, or extracting core design DNA from URLs and screenshots. It is a comprehensive tool for professional UI/UX refinement.
