Skill UI

Neumorphism, or Soft UI, is a contemporary design trend where interface elements appear extruded from the background material itself. This guide details the core principles—unified colors and dual shadows (light highlight and dark shadow)—and provides comprehensive implementation examples for web (CSS), iOS (SwiftUI), and cross-platform (Flutter) development. Use this style when a subtle, soft, and integrated aesthetic is desired.

A fast, grep-based linter that checks for common design system violations in CSS and component code, such as hardcoded colors, raw pixel values, and deprecated syntax. It provides immediate automated feedback to ensure code adheres to established design tokens and best practices.

This skill analyzes your project's current StyleSeed setup, detects outdated engine files, and safely updates the core components, skills, and rules. It follows a structured, non-destructive process, ensuring that user-defined code, such as theme.css and custom components, remains untouched while applying necessary upgrades.

Utilizes Expo DOM components to render web code verbatim inside a webview on native platforms, while maintaining native rendering on the web. This enables developers to integrate web-only libraries (such as charting tools, syntax highlighters, or complex CSS layouts) and incrementally migrate existing web components into a React Native application without substantial rewriting.

A comprehensive guide for creating cinematic, fluid background hero sections using advanced web technologies. It leverages WebGL, complex CSS gradients, and Canvas to generate dynamic, atmospheric visuals. Ideal for video intros, SaaS landing pages, and marketing posters that require a sophisticated, high-impact background.

A modular and highly customizable looping CSS animation template designed for marketing hero sections and video openers. It combines multiple dynamic elements, such as rotating type rings, animated globes, ticking timers, and floating parallax labels, allowing designers to create modern, cinematic, and attention-grabbing digital visuals.

A template designed for creating educational and marketing explainer animations with a strong retro, 8-bit pixel aesthetic. Utilizing pure CSS keyframes for seamless looping, the design features a central pixel mascot, kinetic text displays, and a dynamic timeline ribbon. Perfect for conveying information in a nostalgic style without relying on JavaScript.

This tool enables web interaction using natural language descriptions instead of complex CSS selectors. By utilizing a specialized page-agent and an LLM-driven tool-call loop, users can simply state their goal (e.g., "Fill the search box with cats and submit"). It is ideal for dynamic web pages, ambiguous structures, or quick, one-shot interactions where robust selector writing is impractical. The system provides graceful degradation if the advanced page-agent is unavailable.
