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

• Potentially malicious external URL detected (high risk: 0.90). The runner may invoke "npx -y @command-center/command-center --no-open" (which downloads and executes the remote npm package @command-center/command-center at runtime — see https://www.npmjs.com/package/@command-center/command-center), so remote code is fetched and executed during skill runtime.
