Build end-to-end tests with TestDriver.ai, an AI code reviewer that runs every pull request in a real desktop sandbox, finds bugs, and creates regression tests for web, Electron, and native apps.

A comprehensive guide for implementing Typography First Design across web and mobile applications. This style emphasizes using type as the primary visual element, minimizing decorative UI elements (chroming) to create a highly focused, high-impact, and sophisticated user experience. Includes specific implementation details for CSS, SwiftUI, Flutter, and React Native.

Unship is a dedicated local workflow for front-end developers to compare multiple AI-generated UI alternatives (such as layouts, copy, or flows) directly within a running application environment. Instead of committing to one generated version, it adds temporary source-level variants, allowing for visual comparison. After the user selects the final version, the skill automatically cleans up all unused temporary code and attributes, ensuring a clean, production-ready codebase. Note: This tool is for local iteration only, not for production A/B testing or analytics.

This skill provides comprehensive guidelines for upgrading Expo SDK versions and resolving dependency conflicts. It covers migration paths for React 19, new architecture, and deprecated packages like expo-av.
