Skill UI

A comprehensive collection of agent skills for rigorously auditing digital interfaces and user flows. It evaluates designs against 168 research-backed UX/UI principles, detects common design antipatterns, and provides specialized review for AI-powered interfaces, ensuring adherence to modern best practices.

Upgrades existing websites and apps to premium quality by auditing typography, color, layout, and UI patterns, then applying targeted tweaks within the current stack without rewrites.

This skill provides a comprehensive audit of user interfaces, evaluating screens against Nielsen's 10 Usability Heuristics and modern mobile UX best practices. It systematically checks for critical usability flaws, design inconsistencies, accessibility gaps, and potential dark patterns, ensuring the resulting product delivers a superior and intuitive user experience across all platforms.

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 guides the user to become an expert in authoring comprehensive, implementation-ready design system guidelines for an immersive, exhibit-style brand. It teaches how to structure rules covering design tokens, component anatomy, interaction states, accessibility requirements (WCAG 2.2 AA), and anti-patterns, ensuring consistency across all digital products.

This skill establishes an expert persona and comprehensive workflow for generating high-quality, implementation-ready design system guidelines. It mandates adherence to a specific "Sketch" hand-drawn aesthetic, defines foundational tokens (color, typography, spacing), and enforces best practices regarding accessibility (WCAG 2.2 AA) and structured documentation (e.g., anti-patterns, QA checklists).

This comprehensive guide provides core principles and implementation patterns for adopting the Flat Design aesthetic. It details how to build interfaces across web (CSS), mobile (SwiftUI, Flutter), and cross-platform frameworks, emphasizing zero depth, sharp geometries, and high-contrast solid colors while strictly avoiding shadows, gradients, and bevels. Use this when aiming for a modern, minimalist, and clean UI/UX experience.
