    About this skill

    What it does

    Nex Page Watch is a production-ready Chrome Extension (Manifest V3) that monitors web pages for content changes. It provides a complete, "no-build" codebase using vanilla JS, HTML, and CSS. When a monitored page changes, users receive a browser notification and a detailed visual diff highlighting additions, removals, and word-level modifications.

    Why use this skill

    Unlike basic scaffolding prompts, this skill delivers a fully functional, shipped product. It bypasses the complexity of modern build chains, offering a "Load Unpacked" workflow that is perfect for rapid prototyping or immediate deployment. It solves the architectural challenge of performing heavy diffing operations in an extension by utilizing offscreen documents, ensuring the browser remain responsive.

    Supported architecture & features

    • Manifest V3: Built on the latest Chrome extension standards.
    • Offscreen API: Off-thread processing for performance-intensive diffing.
    • Alarms & Storage: Reliable background scheduling and local data persistence.
    • Vanilla Stack: Zero dependencies—no npm, no Webpack, no Vite.

    The Output

    You receive the complete assets/extension/ source directory containing the manifest, background scripts, content scripts, and UI files. The agent also provides a comprehensive guide on the developer loop, customization, and Web Store packaging steps.
