Skill UI

A comprehensive, systematic framework for auditing and improving web UI designs and frontend code. It teaches core principles like grayscale-first design, constrained scaling (for spacing, type, and color), and establishing clear visual hierarchy. Use this guide when needing to refine an existing UI that 'looks off,' or requires professional structural and aesthetic improvements.

This skill allows users to build and maintain complex UI components and full screens directly within Figma using the Figma MCP. It rigorously enforces a defined design system (like Rayna UI) by validating design tokens, applying craft rules, detecting anti-patterns, and ensuring visual consistency. Ideal for creating new components, composing entire dashboards or landing pages, or auditing existing files for compliance.

This skill performs a comprehensive usability audit and heuristic evaluation of interactive user interfaces (UIs). It goes beyond mere visual aesthetics, assessing whether a system is intuitive, easy to learn, and functional for a first-time user. Use it when auditing complex tools, editors, or apps to ensure the user can complete primary tasks without needing extensive instructions or guidance.
