Skill UI

Provides a comprehensive production checklist specifically for WebContainer applications built using the StackBlitz SDK. This guide helps developers ensure that their web applications are robust and ready for deployment by checking essential aspects like security headers, cross-browser compatibility, and necessary fallback mechanisms.

This skill establishes an autonomous, iterative build loop for continuous website development. It functions as an agent that reads tasks from a 'baton' file, utilizes the Stitch MCP tools to generate structured web pages, integrates the generated HTML assets into the main site structure, and finally updates the baton file with the next required task. It supports end-to-end, programmatic site building and includes optional visual verification using Chrome DevTools.

A browser-based skill for search, web scraping, login-required actions, and dynamic page interaction. Use it to access real websites, extract content, and operate pages in a live Chrome environment.

Captures complete, full-page screenshots of any modern web page using the Chrome DevTools Protocol (CDP). Unlike standard tools, this utility handles Single Page Applications (SPAs), scrolling content, lazy-loaded images, and complex scroll containers, ensuring the entire visible content is captured in a single, high-fidelity PNG file. Ideal for documenting complex web flows and testing.

A comprehensive playbook covering advanced V8 and Chromium exploitation techniques. It details complex vulnerabilities such as JIT type confusion, incorrect bounds elimination, and pointer compression bypass. This guide is essential for understanding the mechanisms required to achieve renderer RCE and sandbox escape in modern browsers.

This skill automates the NotebookLM AI research tool using browser automation via the Claude Chrome extension. It allows users to programmatically create new notebooks, add multiple sources (URLs, documents, text), and trigger complex output generations, such as mindmaps, audio overviews, and briefing documents, without manual clicking. Ideal for researchers and builders managing high volumes of source material.

A comprehensive style guide and implementation reference for the Retro Futurism aesthetic. Perfect for designing interfaces that evoke the 1950s and 1960s space age, atompunk, or mid-century modern vibes. It outlines core principles, color palettes, typography, and provides cross-platform code examples (CSS, SwiftUI, Flutter, React Native) to achieve sleek, aerodynamic, chrome finishes.

This comprehensive guide provides developers with the foundational principles and actionable code examples for implementing the Y2K aesthetic. Learn how to achieve the signature look—incorporating chrome metallic effects, amorphous blob shapes, digital grid backgrounds, and neon glows—across web (CSS), iOS (SwiftUI), and cross-platform (Flutter) environments.

This template provides an editorial-minimalist web layout, inspired by high-end magazines. It features a warm monochrome palette, classic serif displays, and clean grotesque body text, emphasizing macro-whitespace and subtle ambient micro-animations. It is perfect for portfolio sites, long-form articles, or any content-heavy design needing a sophisticated, literary feel.

This skill drives an existing browser instance using the Chrome DevTools Protocol (CDP). It is essential for complex web automation tasks that require visible interaction, JavaScript execution, or handling authenticated, stateful sessions. Use it when static data fetching is insufficient, such as simulating user logins, interacting with iframes, or performing visual verification. Supports headless and remote environments.

A comprehensive skill to extract and transcribe subtitles from any YouTube video URL. It utilizes a two-stage approach: first, attempting fast extraction via the yt-dlp CLI tool; failing that, it falls back to advanced browser automation using Chrome DevTools MCP to scrape the transcript panel content directly from the webpage DOM. The output is always a clean, timestamped plain text file.

This guide provides a comprehensive methodology for the reverse engineering of browser extensions (Chrome/Firefox). It covers analyzing the manifest, tracing background workers, content scripts, and recovering sensitive logic like credentials or network traffic. Essential for security research, malware investigation, and supply chain security auditing.
