MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.80). The skill's runtime installs npm packages when node_modules is missing (via "npm install") and fetches/executes remote code such as the wcag-contrast package from https://registry.npmjs.org/wcag-contrast/-/wcag-contrast-3.0.0.tgz, which is a required dependency executed by the script.
