Skill UI

This skill covers modern frontend development patterns for React and Next.js. It includes state management, performance optimization, and UI best practices. Use it for building performant user interfaces and following industry standards in web development workflows.

This skill enables AI agents to control the user's visible browser interface directly. It supports navigation, clicking, typing, and debugging actions within the browser pane. The agent can take screenshots, interact with web tools, and handle login processes. It operates via a live Automation REPL without requiring code mode, ensuring safe and scoped interactions within the current session.

This skill provides a core component library and design system patterns for building consistent user interfaces. It emphasizes using design tokens for spacing, color, and typography instead of hard-coded values. Includes patterns for layout, forms, and interactive elements like buttons and inputs, ensuring maintainable and scalable UI development.

This skill provides modern React UI patterns for handling loading states, error management, and data fetching. It covers best practices like showing spinners only when necessary, surfacing errors to users, optimistic updates, and graceful degradation. Use this when building UI components, managing async data, or creating responsive user interfaces with proper feedback mechanisms.

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.

A comprehensive guide covering the aesthetic and technical implementation of floating User Interface (UI) elements. Learn how to create detached, elevated components, such as cards and navigation bars, giving the application a light, airy, and modern feel across Web (CSS), iOS (SwiftUI), and Flutter platforms. Key principles include soft shadows, generous margins, and pill shapes.

A comprehensive technical guide for implementing the nostalgic Frutiger Aero aesthetic across web and mobile platforms. This style, popular in the mid-2000s, is characterized by glossy gradients, translucent glass effects, and nature-inspired motifs (sky, water, grass), creating an optimistic, skeuomorphic user interface experience.

This tool provides comprehensive automation for core GitLab operations, streamlining the entire development lifecycle. Users can manage projects, track issues, review merge requests, manage branches, and monitor CI/CD pipelines. It leverages a unified API interface to handle complex workflows, ensuring efficiency in version control and collaborative development environments.

Core principles for designing user interfaces on Apple platforms. Covers accessibility, system colors, typography, motion, and privacy. Ensures consistency with Apple's design language across iOS, macOS, and visionOS.

This skill provides guidance on Apple's Human Interface Guidelines for designing user interfaces across different Apple platforms including iOS, iPadOS, macOS, tvOS, visionOS, and watchOS. It covers key principles like touch-first interaction for mobile, pointer and keyboard usage for desktop, and spatial interaction for visionOS. It helps developers and designers adapt layouts, navigation, and interactions to match platform conventions and user expectations, ensuring a native feel and consistent brand experience.

This comprehensive guide outlines Apple's Human Interface Guidelines (HIG) for various technologies and user flows (e.g., Siri, Apple Pay, HealthKit, ARKit, Generative AI). It teaches developers how to ensure their applications feel natively integrated, respect user privacy, and adhere to established platform patterns across iOS, macOS, and other Apple devices. Essential reading for building high-quality, compliant, and seamless user experiences.

This comprehensive guide outlines the principles and technical implementation for creating highly accessible, high-contrast user interfaces. It ensures WCAG AAA compliance by specifying pure black/white color pairings, clear boundaries, and legible typography across web (CSS), iOS (SwiftUI), and Android (Flutter) platforms. Ideal for applications requiring maximum legibility and stark visual impact.
