What problem does it solve? Frontend UI work often ships with generic aesthetics, design system deviations, accessibility gaps, and unclear action hierarchies that only surface late in review. This Skill provides a structured review framework with quality pillars, scoring gates, and repair contracts so UI implementations are evaluated consistently before merge. ## Core Features & Use Cases - Design Review Mode: Evaluate existing UI against design system compliance, three quality pillars (Frictionless, Quality Craft, Trustworthy), accessibility standards, and code quality. - Creative Frontend Mode: Create distinctive interfaces with a committed aesthetic direction, avoiding generic AI-generated visual patterns. - Screenshot Score Gate: Score desktop, tablet, and mobile screenshots across weighted dimensions with an 88/100 pass threshold. - Use Case: During a PR review of a new dashboard, run the full option/scene × viewport matrix, produce a structured issue inventory with severity and repair requirements, and hand off a complete repair batch before re-review. ## Quick Start Review this frontend pull request for design system compliance, accessibility, and responsive behavior across desktop and mobile viewports.
