Skill UI

Provides Playwright-powered browser automation that detects dev servers, writes tests to /tmp, launches a visible Chromium, and exercises login flows, responsive layouts, form submissions, link checks, or any browser task to validate web functionality.

Provides a comprehensive workflow for managing feature flags, running A/B/multivariate experiments, and analyzing user cohorts using PostHog. The guide covers implementing flag evaluation both client-side (browser) and server-side (Node.js), and demonstrates how to programmatically set up, track, and query experiment results via API calls (cURL/Bash).

This skill guides the complete setup and configuration of PostHog SDKs for modern applications. It covers best practices for implementing client-side (browser) and server-side (Node.js/Python) event tracking. Users will learn how to install the necessary SDKs via npm or pip, manage environment variables for both Project API Keys and secure Personal API Keys, and initialize the tracking service correctly to ensure accurate and reliable event capture in PostHog.

Provides a comprehensive guide and framework for executing end-to-end (E2E) tests. It simulates real user interactions across the entire application stack, covering browser UI, API calls, and database operations. The guide details best practices like implementing the Page Object Model (POM), configuring multi-browser environments (Playwright, Cypress, Selenium), and establishing robust error handling mechanisms to ensure high application stability and quality.

This guide provides a comprehensive, multi-language walkthrough for installing and initializing the Sentry SDK in various environments (Node.js, Python, Browser). It covers essential concepts like DSN setup, using secure environment variables, configuring release versions, and implementing basic error and performance tracking for robust observability in production and CI/CD pipelines.

This skill validates web applications across diverse browsers (Chromium, Gecko, WebKit) and real mobile devices. It supports both local testing using Playwright and scalable cloud testing via major platforms like BrowserStack, Sauce Labs, and Kobiton. Use it when ensuring consistent UI/UX, correct CSS rendering, and functional JavaScript behavior regardless of the target environment or device type.

This comprehensive workflow provides a complete cycle of quality assurance for software development. It covers every stage from defining the test strategy (TDD, Unit Testing) through integration, E2E testing, browser automation, performance profiling, security scanning, and final code review. Use this when setting up robust testing infrastructure or ensuring production-ready software quality.

A comprehensive guide covering modern web game development principles. It details framework selection (Phaser, Three.js), implementing WebGPU, performance optimization strategies like asset compression and object pooling, adhering to browser constraints, and utilizing PWA capabilities for cross-platform gaming experiences.

Run Playwright tests on BrowserStack's cloud grid for cross-browser and cross-device testing. Supports configuring browser projects, running tests remotely, retrieving build results, listing available browsers, and setting up local tunneling for private environments.

Guides writing and running Odoo TransactionCase, HttpCase, and browser-tour tests, covering setup, tagging, and CLI commands so you can add CI-friendly automation for models and controllers.

A production-grade toolkit designed for robust Playwright end-to-end testing. This AI assistant guides users through the entire testing lifecycle: generating tests from specifications, diagnosing and fixing flaky failures, migrating from Cypress or Selenium, and integrating with test management systems like TestRail and BrowserStack. It enforces best practices and ensures high test quality and coverage.

Intelligent multi-strategy web scraper that selects between static WebFetch, browser automation, curl/bash, and WebSearch paths to extract structured tables, lists, pricing, and other data, with pagination handling, validation confidence, transforms, and CSV/JSON output for monitoring workflows.
