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

• Potentially malicious external URL detected (high risk: 1.00). The skill fetches guidelines at runtime from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md via WebFetch and uses the fetched content to control the rules and output format, so the external URL directly controls agent instructions.
