    Example session with this skill installed

    I want to build an extension that saves my Amazon and Shopify orders locally so I can track my spending without linking my bank account. Do you have a template for this?

    • Read your context and instructions
    • Compiled the nex-receipt-vault

    I've initialized the Nex Receipt Vault extension. It includes specialized detectors for Amazon and Shopify, a local storage service worker, and a spending dashboard. You can load it via 'Load unpacked' in chrome://extensions. Files are in assets/extension/.

    Connects securely to your tools. The creator never sees your data.

    About this skill

    Secure Receipt Scraper & Dashboard

    Nex Receipt Vault is a production-ready, Manifest V3 Chrome extension designed for privacy-first purchase tracking. It eliminates the need for intrusive bank connections by capturing order data directly from browser confirmation pages. This skill provides the complete, working source code—originally a shipped product—built on a vanilla JS, HTML, and CSS architecture.

    What it does

    The extension monitors active tabs for order-confirmation patterns. Once detected, its specialized extraction engine parses merchant details, itemized lists, totals, and dates. All data is stored locally on the user's device. The included popup provides a comprehensive spending dashboard and history view. Key features include:

    • Multi-Platform Detectors: Pre-built support for Amazon, Shopify, WooCommerce, and more.
    • Intelligent Classification: Distinguishes between standard pages and valid receipts.
    • Zero-Build Workflow: Edit and reload instantly without npm or bundlers.
    • Privacy-Centric: No accounts, no servers, and no third-party data access.

    Why use this skill?

    Building reliable web scrapers that survive DOM changes is difficult. This skill saves days of development by providing a field-tested architecture for DOM-based data extraction. It serves as both a functional tool and a masterclass in professional extension development, covering everything from background service workers to local storage persistence.

    • No automated testing suite included.
    • Scraper logic requires manual updates if merchant DOM changes.
    • Requires manual reload in developer mode: no HMR.
