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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly instructs the agent to WebFetch official Next.js upgrade documentation at runtime (e.g., https://nextjs.org/docs/app/guides/upgrading/codemods and https://nextjs.org/docs/app/guides/upgrading/version-15), and then to follow those fetched instructions to perform upgrades, so the fetched external content directly controls agent behavior and is a required runtime dependency.
