Skill UI

An expert-level skill set covering the entire spectrum of user-centered design. Mastery includes building scalable design systems using atomic principles and design tokens, conducting deep user research (usability testing, persona creation), ensuring WCAG accessibility compliance, and managing cross-platform implementation (web, mobile, desktop). Ideal for developing complex, inclusive, and highly structured digital products.

Wraps any existing HTML artifact (landing page, dashboard, etc.) with a live sidebar panel of controls. This panel allows users to instantly adjust design variables—such as accent color, typography scale, layout density, and dark mode—by rewriting CSS custom properties in real time. All changes are persisted via localStorage, enabling continuous exploration and variant testing without losing state.

This skill guides the planning and structuring of Figma prototypes specifically for usability testing and user research. It helps define the precise scope (in/out scope), specifies every interaction detail (trigger, elements, animations), builds comprehensive flow diagrams, and generates detailed test task scripts. It ensures the prototype is the minimum viable version needed to answer the research questions, preventing scope creep and over-engineering.

Generates a comprehensive and actionable UX research plan for any product feature or question. This skill covers the entire research lifecycle, including defining objectives, selecting methodology (e.g., usability testing, interviews), creating participant screeners, writing discussion guides, and structuring a synthesis framework. Ideal for product managers and UX researchers needing a structured approach to validate assumptions and drive design decisions.

Measure rendered UI layout with reproducible spatial metrics and a separately assessed usability review. Distinguishes objective measurements from vision judgments and user testing for AI-generated interfaces.

This skill enables you to create interface designs, wireframes, and comprehensive design systems. It covers user research methodologies, accessibility standards like WCAG, and modern design tools such as Figma. The expert specializes in design tokenization, component libraries, and cross-platform consistency. Capabilities include usability testing, information architecture, visual design, interaction design, and design system governance. Ideal for building accessible, user-centered digital experiences across web, mobile, and desktop platforms.
