    Example session with this skill installed

    I need to build a Chrome extension that takes a scrolling screenshot of a whole webpage and lets me save it as a PDF.

    About this skill

    Professional Full-Page Capture Chrome Extension

    This skill delivers the production-ready source code for the Nex Full Capture extension, a robust Manifest V3 tool that enables one-click scrolling screenshots. Unlike basic AI-generated boilerplates, this is a fully realized, shipped product that handles complex tasks like viewport stitching via offscreen documents and local PDF generation.

    What it does

    • Full-Page Scrolling: Orchestrates background scripts to scroll, capture, and stitch page segments.
    • Multiple Export Formats: Offers PNG downloads, PDF generation via local scripts, and clipboard support.
    • Zero-Build Architecture: Built with vanilla JS, HTML, and CSS for a lightning-fast developer loop—just load and go.
    • MV3 Compliant: Uses the latest Chrome Manifest V3 standards, including offscreen documents and background workers.

    Why use this skill?

    Building a reliable scrolling capture tool is notoriously difficult due to lazy-loading elements and coordinate math. This skill provides a proven, tested implementation that handles these edge cases out of the box. It serves as both a powerful utility and a high-quality "action-on-click" template for developers looking to build their own browser-based tools without the overhead of heavy frameworks or build steps.
