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

• Potentially malicious external URL detected (high risk: 0.70). The skill explicitly runs an npx command to fetch and execute the @next/codemod package at runtime (npx @next/codemod@latest — https://www.npmjs.com/package/@next/codemod), which downloads and runs remote code and is presented as a required step for the upgrade.
