Skill UI

This skill generates robust, production-grade Appium automation scripts for both Android and iOS. It supports multiple languages (Java, Python, JavaScript) and guides users through best practices for cross-platform testing, including proper locator strategies, explicit waiting, and complex gestures. Ideal for automating mobile QA processes on local emulators or cloud real device farms.

A comprehensive, four-phase methodology for debugging complex software issues. It guides users through root cause investigation, pattern analysis, hypothesis testing, and controlled implementation. The core principle emphasizes finding the underlying cause rather than applying quick, symptomatic fixes, ensuring robust and reliable code improvements across various failure scenarios.

This guide details how to integrate Expo and React Native into existing native iOS or Android applications (brownfield development). It addresses the core challenge of adopting new technology incrementally, outlining two distinct approaches: Isolated (consuming prebuilt AAR/XCFramework) and Integrated (adding sources directly to existing build systems like Gradle/CocoaPods).

A comprehensive guide for developers on creating and writing native modules and views using the Expo Modules API. It covers platform-specific implementation details for Swift (iOS), Kotlin (Android), and TypeScript. Use this when integrating system APIs, wrapping platform SDKs, or building complex native functionality that goes beyond standard React Native components.

Use @expo/ui to build high-fidelity, native user interfaces across iOS and Android from a single React codebase. This library renders real native UI components, such as SwiftUI on iOS and Jetpack Compose on Android. It promotes a universal component layer for cross-platform consistency, while also providing controlled access to platform-specific optimizations and drop-in replacements for existing community libraries.

This comprehensive skill demonstrates advanced usage patterns for Formik, a popular React form handling library. It covers basic form setup, complex validation schema creation using Yup (including conditional logic), field helper utilities, and integrating form submissions with GraphQL mutations for both creation and editing scenarios.

Create highly aesthetic, animation-rich HTML presentations from scratch or convert existing PowerPoint files (PPT/PPTX). This tool focuses on generating distinctive, professional web decks with fixed 16:9 ratios. It supports low-density for keynote talks or high-density for detailed reports, ensuring visual impact and zero dependencies.

This skill is designed to identify subtle and complex logic bugs within a single code file or function. It employs a semi-formal execution tracing methodology, systematically breaking down the suspected bug into five stages: Premises (expected state), Trace (execution path), Divergence (actual deviation), Trigger (reproduction case), and Remedy (fix). It is ideal for scenarios where users suspect code is wrong but cannot specify a concrete failure point.

This skill systematically scans Apple's comprehensive developer documentation, specifically targeting SwiftUI. It identifies deprecated APIs, finds their modern replacements, and updates the expert skill's reference guide. Use this when required to refresh deprecated features, check for new API deprecations after an iOS/Xcode update, or maintain the most current best practices for SwiftUI development.

A sophisticated template designed for creating long-form, magazine-quality articles. Ideal for thought leadership pieces, detailed case studies, or in-depth essays. It includes structural elements like mastheads, pull quotes, figures, and author bios to enhance readability and professionalism across various professional domains.

This template provides a highly flexible, fixed-size 1920x1080 canvas for creating professional presentations. Unlike traditional templates, it allows users to arrange content freely, treating each slide like a composable React component. It enforces strict design constraints (typography, color palette, visual hierarchy) to ensure every page maintains a polished, professional, and unique aesthetic, ideal for portfolios and artistic talks.

This template provides a sophisticated, print-ready document aesthetic, simulating expertly typeset paper on a parchment background. It employs a limited, classic color palette (creamy parchment, ink blue accents) and serif typography. Ideal for creating high-fidelity, professional documents like resumes, long reports, one-pagers, business letters, and portfolios, ensuring the final output feels like an archival print piece rather than a typical web dashboard.
