    Example session with this skill installed

    I need a Chrome extension that automatically rejects cookie popups. Can you build me a Manifest V3 starter based on the Nex Cookie Shield?

    • Read your context and instructions
    • Compiled the nex-cookie-shield-ext

    I have generated the full source for the Nex Cookie Shield in assets/extension/.

    Key files

    • manifest.json (MV3)
    • content.js (Detection logic)
    • popup.html/js (Stats UI)

    To test: Open chrome://extensions, enable Developer Mode, and 'Load unpacked' from the assets folder.

    About this skill

    What it does

    The Nex Cookie Shield skill provides a production-ready, Manifest V3 Chrome extension designed to automatically detect and click "Reject All" on cookie consent banners across the web. Unlike basic AI prompts that might give you a single script, this skill delivers a complete, shipped source code package including background workers, content scripts, and a functional UI for tracking blocked popups.

    Why use this skill

    Developing Chrome extensions from scratch often involves wrestling with Manifest V3 permissions and messaging architectures. This skill solves that by providing a "content-rewriter" archetype that is already architected and ready to ship. It uses a zero-build, vanilla JS/HTML/CSS approach, meaning you can edit code and see changes instantly without worrying about Webpack, Vite, or npm dependencies.

    Supported Features

    • Automated Detection: Sophisticated content scripts to identify and interact with common consent frameworks.
    • Functional Popup: A pre-built UI to toggle the shield and view blocking statistics.
    • Settings & Allowlisting: Persistent storage integration to manage per-site rules and exclusions.
    • Store-Ready Manifest: A fully configured Manifest V3 file optimized for Chrome Web Store submission.

    The Output

    You receive the full source tree in an assets/extension/ directory. This includes the manifest, logic scripts, icons, and settings pages, along with a developer guide for loading the "unpacked" extension and packaging it for distribution.

    • Only detects common consent patterns: may miss custom or obscure banners.
    • No build step: not suitable for TypeScript or framework-heavy modifications.
