    Sample input

    I need a Manifest V3 extension that adds a 'Not Interested' button to YouTube and LinkedIn posts to help train my feed faster.

    Sample output

    I've generated the complete extension source in assets/extension/. Key files:

    • manifest.json: Configured for YouTube/LinkedIn host permissions.
    • platforms/youtube.js: Selectors for video cards.
    • platforms/linkedin.js: Selectors for feed updates.
    • injector.js: Handles button placement.

    About This Skill

    One-Click Algorithm Control

    Nex Feed Filter is a complete, production-ready Chrome Extension (Manifest V3) designed to help users train social media algorithms instantly. It eliminates the friction of multi-click menus by injecting native "Not Interested" buttons directly into feed items across major platforms like YouTube, LinkedIn, X, Instagram, and Reddit.

    What it does

    The skill delivers a fully functional source code package using a clean, vanilla JS/HTML/CSS architecture with no build steps or dependencies. Key features include:

    • Shared Injector Harness: A centralized content script manages button placement and lifecycle across all supported sites.
    • Per-Platform Modules: Modular selectors and native action triggers for 5+ major social networks.
    • Full MV3 Suite: Includes manifest, background service worker, popup UI, and persistent settings via chrome.storage.
    • No-Build Workflow: Ready to "Load Unpacked" immediately for instant developer feedback.

    Why use this skill

    Instead of prompt-engineering a complex multi-file extension from scratch, you get a battle-tested architecture that handles the tricky parts of DOM injection and cross-platform consistency. It's the perfect starting point for developers building feed-control tools, content rewriters, or any extension requiring per-site modularity.

    Use Cases

    • Deploy a ready-to-ship Chrome extension for personalized feed filtering.
    • Fork a modular content-script architecture for multi-site DOM manipulation.
    • Learn the no-build developer loop for rapid Manifest V3 prototyping.
    • Customize social media algorithms with one-click native action triggers.
