    License Guardian — dependency license compliance for Claude

    Example session with this skill installed

    Run a license audit on the current node project. We are planning to ship this as a commercial desktop application, so we need to avoid any GPL or AGPL code in the final bundle.

    • Read your context and instructions
    • Compiled the license guardian

    I have completed the license audit for the current npm project. I scanned the node_modules directory and analyzed the results against your distribution model as a commercial desktop application.

    Findings Summary

    The scan identified 142 packages in total. Most dependencies are MIT or BSD licensed and safe for your desktop application. However, two packages represent significant risk:

    screen-capture-utility (GPL-3.0): As a desktop binary, shipping this package triggers the requirement to open-source your entire application. This is a blocker for your commercial release.
    2.

    internal-logger (AGPL-3.0): This is a transitive dependency of your debugging suite. If this code is bundled into the production build, it carries high risk.
    3. unknown-helper: No license field found in package.json. This could be proprietary or unlicensed code.

    Next steps

    • Replace screen-capture-utility with a MIT-licensed alternative like desktop-screenshot.
    • Check if internal-logger can be moved to devDependencies to prevent it from shipping in the desktop binary.
    • Manually inspect the LICENSE file for unknown-helper in the project root.

    About this skill

    Catch risky open-source licenses before they ship. License Guardian scans your installed npm or Python dependency tree, including deeply nested transitive packages, and classifies each package’s declared license. It runs entirely offline, so private codebases stay private.

    The key difference: it evaluates findings in the context of your distribution model. A GPL-licensed build tool you don’t ship is different from GPL code bundled into your product. License Guardian helps separate potential non-issues from dependencies that deserve a closer look.

    What's included

    ! npm scanner: analyze node_modules and generate a classified report ! Python scanner: scan any installed virtual environment ! Offline analysis for private and internal codebases

    Not legal advice or a substitute for counsel. Just a faster way to find the license risks worth investigating in a sprawling dependency tree.
