    Example session with this skill installed

    Every week I need the latest product listings from our supplier catalog at https://parts.example.com — roughly 2,000 items with price, stock status, and SKU. Right now someone checks the pages by hand; I can already log in and browse the catalog myself. I also want a daily check that flags items whose price or stock changed since the last pull, without re-reporting the same changes. Can you build me a durable capability package for this: a tested script for the bulk catalog export and another for change detection, plus the docs my agent needs to run both without re-exploring the site? Keep everything local under /home/agent/work/suppliers.

    Summary

    Built and verified a reusable capability package for parts.example.com: one bulk catalog export and one change monitor, both encoded from a live browser investigation and validated end to end.

    All four gates passed: static output, live sample fetch, bad-SKU negative case, and the full export-to-diff chain.

    Next steps

    • Schedule the monitor as a daily job; snapshots persist in tmp/
    • Request contract-price view access to close the 6% restricted-rows gap
    • Reuse the export directly: "export catalog for category X"

    About this skill

    The problem

    One-off browser scraping is fragile and hard to scale. Manual exploration must be repeated every time a site layout changes or a new batch of data is needed, leading to inconsistent results and wasted developer time.

    What it does

    • Discovers stable API endpoints, request patterns, or DOM paths within a live browser session.
    • Encodes verified interaction paths into reusable Python and JavaScript automation packages.
    • Generates a SKILL.md manifest that teaches other AI agents how to execute the workflow.
    • Runs automated verification gates to test for successful data extraction and error handling.
    • Produces structured local artifacts for bulk data pulls, site monitoring, or authenticated workflows.

    Frameworks & tools

    Python, JavaScript, browser-native APIs (Fetch/XHR), and DOM selectors.

    Why this beats prompting it yourself

    Generic prompts often hallucinate selectors or fail on dynamic, single-page applications. This tool uses a disciplined discovery lifecycle to find the least fragile path, verifies it with real execution, and packages it for long-term durability rather than just a single successful run.

    Use cases

    • Extracting large-scale product catalogs or search results from e-commerce platforms.
    • Monitoring dashboards for changes where data is hidden behind a login.
    • Automating repetitive form submissions or administrative web tasks.
    • Converting manual research into a reusable data pipeline for other agents.

    Known limitations

    Does not bypass CAPTCHAs, paywalls, or rate limits. Requires an active browser session with appropriate user permissions already established.
