    Sample input

    I want to build an extension that scans the current page for email addresses and lets me export them to a CSV file from a popup.

    Sample output

    I'll scaffold this as a Scraper Archetype. Here is your nex-email-scanner project:

    • manifest.json: Includes activeTab and storage permissions.
    • content.js: Scans DOM for regex-matched emails.
    • popup.html: Dark-themed UI with "Scrape" and "Download CSV" buttons.

    About This Skill

    The Ultimate Factory for Chrome Extensions

    Ship production-ready Manifest V3 extensions without the overhead of modern build tools. This skill implements a battle-tested "Vanilla MV3" pipeline used to launch 23 successful extensions. By bypassing Vite, npm, and complex bundlers, you move from idea to 'Load Unpacked' in minutes, not hours.

    What it does

    • Scaffolds Complete Projects: Generates the manifest, background service workers, content scripts, popups, and options pages according to the canonical MV3 layout.
    • Selects the Optimal Archetype: Automatically maps your idea to one of 7 high-conversion archetypes (Overlay, Scraper, Autofill, Side Panel, etc.) to ensure correct architectural decisions from day one.
    • Automates Compliance: Generates a Chrome Web Store-ready privacy policy and store listing checklist tailored to your extension's specific permissions.
    • Zero-Dependency Assets: Includes a Python script to generate all required icon sizes from a single design, plus dark-themed, responsive UI templates.

    Why use this skill?

    Prompting an AI for an extension usually results in fragmented code snippets. This skill provides a cohesive, end-to-end pipeline. It enforces stateless service worker patterns to prevent common MV3 lifecycle bugs and implements a "No-Build" dev loop—edit, reload, and test instantly in Chrome. It’s designed for developers who want to ship fast and maintain high code quality without the "node_modules" bloat.

    Supported Patterns

    • Manifest V3 (Vanilla JS, HTML5, CSS3)
    • Chrome Extension APIs (Storage, Scripting, Action, SidePanel)
    • Python (Pillow) for automated icon generation

    Use Cases

    • Scaffold a full MV3 project from a single-sentence idea
    • Generate store-compliant privacy policies and listing descriptions
    • Convert an existing idea into the correct architectural archetype
    • Automate icon resizing and asset generation for the Web Store
