Skill UI

Guides building native-feeling macOS interfaces, covering layout/composition, traffic lights, draggable chrome, shortcuts, light/dark mode, visuals, animations, drag-and-drop, and onboarding for desktop tools whether React, Electron, or native.

This skill provides a collection of curated micro-interactions, easter eggs, and clever UX patterns designed to elevate standard digital interfaces. Use it when polishing an existing feature or designing unique web behaviors (like hover states, loaders, or transitions) to move beyond generic templates and establish a strong, memorable brand personality. Focus on adding delightful, high-performance details that feel premium.

This framework analyzes foundational design principles—such as affordances, signifiers, and conceptual models—to create products that are highly intuitive and discoverable. It guides analysis by bridging the 'Gulf of Execution' and the 'Gulf of Evaluation.' Use this when diagnosing confusing user interfaces, poor usability, or needing to ensure a product is robustly human-centered and easy to understand.

Guides frontend designer-engineers to deliver memorable, production-ready interfaces by defining an aesthetic stance, scoring feasibility with DFII, and translating every intentional decision into code, typography, motion, and texture.

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.

A comprehensive skill for generating non-generic, professional frontend interfaces, perfect for landing pages, portfolios, and product redesigns. This agent enforces a strict design methodology: reading the user's brief (audience, vibe, constraints) first, configuring global design dials (variance, motion, density), and recommending real, industry-standard design systems (like Material or Fluent UI) to ensure the output is always polished and contextually appropriate.

Guidelines for crafting industrial brutalist interfaces that merge Swiss print and military terminal aesthetics, emphasizing rigid grids, stark typography, utilitarian color, and analog degradation for data-heavy dashboards or editorial sites.

Protocol for crafting premium utilitarian editorial-style interfaces with warm monochrome palettes, flat bento grids, muted pastels, strict typography, and very restrained motion for high-end workspace-like frontends.

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 expert skill audits and designs user interfaces for the Apple ecosystem (iOS, macOS, watchOS, visionOS) against the official Human Interface Guidelines (HIG). It checks crucial elements like contrast ratios (WCAG standards), minimum tap-target sizes, and adherence to modern design languages like Liquid Glass. Use it when reviewing mockups or developing native-feeling Apple apps to ensure accessibility and optimal user experience.

StyleSeed is a comprehensive design judgment engine designed to elevate the aesthetic quality of AI-generated user interfaces. It codifies 69 visual rules covering color discipline, spatial rhythm, information hierarchy, and motion feedback. By integrating these principles, developers can ensure that AI output looks professionally designed and polished, rather than simply generated. Includes React components, Tailwind CSS implementation, and actionable design guidelines.

A comprehensive, expert-level guideline for building Agentic User Interfaces (UIs). This system emphasizes conversational interactions, clear outcomes, and minimal user controls, allowing users to delegate complex tasks to AI. It provides structured rules covering color tokens, typography, accessibility (WCAG 2.2 AA), and component anatomy for professional developers and designers.
