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

• Potentially malicious external URL detected (high risk: 0.70). The skill instructs running "npx -y firebase-tools@latest" which fetches and executes remote code from the npm registry (e.g. https://registry.npmjs.org/firebase-tools), so it depends at runtime on external code that is executed.
