Skill UI

Browser automation expert for debugging flaky tests and running long-lived scrapers using Playwright/Puppeteer, focusing on robust selectors, auto-waits, isolation, and anti-detection practices.

A production-grade framework for executing high-performance, robust browser automation and web scraping using Playwright with the Go language. This skill specializes in handling complex Single Page Applications (SPAs), emulating human behavior (e.g., random typing delays, Bezier mouse movements), and implementing advanced stealth techniques to bypass anti-bot systems like Cloudflare. It emphasizes architectural best practices, such as using contexts for isolation and structured logging.

This bundle collects comprehensive diagnostic information about the WebContainer environment. It checks the boot state, file system integrity, running process list, and modern browser support (e.g., SharedArrayBuffer, cross-origin isolation). Essential for developers integrating with StackBlitz SDK or WebContainers to troubleshoot complex development issues.

This guide details how to install and configure the WebContainer API, enabling client-side Node.js execution directly in the browser. It also provides instructions for integrating the StackBlitz SDK, which is used for embedding highly interactive code editors into web applications. The guide covers necessary dependency installations, code examples, and crucial HTTP header configuration (COOP/COEP) required for cross-origin isolation and secure operation.
