Browser-Native Dependency Scanner

When to use

Use this skill when the user:

• asks to audit, scan, or check JavaScript/Node.js dependencies for replacements
• wants to modernize a project by removing polyfills and outdated utility packages
• asks "which of my deps can be replaced with browser built-ins?"
• wants to know if packages like axios, lodash, moment, uuid, etc. are still needed
• is trying to reduce bundle size by switching to native APIs
• asks about browser-native alternatives to a specific npm package

Inputs required

• A target directory (or the current working directory) that contains a package.json.
• Optionally: desired output format (terminal table, markdown report, or JSON).
