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

• Potentially malicious external URL detected (high risk: 0.70). The skill explicitly instructs installing and running the diffity CLI at runtime via "npm install -g diffity" which will fetch and execute code from the npm registry (e.g. https://registry.npmjs.org/diffity), so the external package is a required runtime dependency that can execute remote code.
