Skill UI

This guide provides best practices for building flexible, maintainable, and scalable React components. It emphasizes using composition patterns and compound components to avoid 'boolean prop proliferation,' while also detailing advanced concepts in component architecture, state management, and modern implementation techniques (including React 19 APIs). Ideal for refactoring complex systems or designing reusable component libraries.

This skill covers building user interfaces using a core component library and design system patterns. It emphasizes using design tokens for spacing, color, and typography instead of hard-coded values. Includes components like Box, Button, Input, and layout patterns for forms and lists. Ensures consistent styling and behavior across the application.

This skill provides production-ready smart contract templates for building decentralized finance applications. It covers essential components such as staking mechanisms, automated market makers (AMMs), governance token systems, and lending protocols. Ideal for developers implementing Solidity-based DeFi infrastructure, including yield farming and flash loan integrations. Use this when creating secure and scalable blockchain financial systems.

Design-It routes frontend design tasks to 48 specific UI styles, avoiding generic aesthetics. It triggers for websites, app screens, or UI components requesting a specific aesthetic. The skill guides AI agents to select appropriate color palettes, typography, and layout principles like the 60-30-10 rule. It supports various frameworks including React, Vue, and mobile platforms.

This skill enables the creation of production-ready Discord bots using Discord.js for JavaScript and Pycord for Python. It covers essential features including gateway intents, slash commands, interactive components, rate limiting, and sharding strategies to ensure scalability and performance in live environments.

Convert narrative technical documents into grounded Mathematical Problem Specifications (MPS) with variables, constraints, objectives, and uncertainty. Enforces zero-inference protocol, extracts structured components, and identifies missing information for formalization.

This skill creates comprehensive technical documentation from existing codebases. It analyzes architecture, design patterns, and implementation details to produce long-form technical manuals and ebooks. The documentation includes executive summaries, architecture overviews, design decisions, core components, data models, and deployment considerations. It helps onboarding new team members and supports long-term maintenance by providing clear, structured, and accessible technical references in Markdown format.

This skill guides the development of production-grade APIs, MCP servers, and enterprise backends using modern C#/.NET best practices. It covers essential architectural components such as dependency injection (DI), advanced caching strategies (e.g., Redis), data access optimization with EF Core/Dapper, and implementing resilience patterns, ensuring robust and scalable software design.

Build native iOS and Android UI components using React with the @expo/ui package. Supports universal cross-platform components and platform-specific SwiftUI or Jetpack Compose rendering. Ideal for Expo SDK 56+ projects needing high-performance native interfaces without writing separate native code.

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.

Orchestrate comprehensive legacy system modernization using the strangler fig pattern. This workflow enables gradual replacement of outdated components while maintaining continuous business operations through expert agent coordination. It includes phases for legacy assessment, test coverage establishment, and incremental migration implementation to minimize disruption and maximize modernization velocity.

This skill enforces strict architectural and performance standards for senior frontend engineers. It guides the creation of scalable React applications using Suspense-first data fetching, feature-based organization, and strict TypeScript discipline. Use it when building components, adding features, fetching data, or refactoring code to ensure maintainability and performance.
