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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly requires running npx to fetch and execute remote packages at runtime (e.g., "npx -y skills add firebase/agent-skills -y" and "npx -y firebase-tools@latest") and references the agent-skills repo at https://github.com/firebase/agent-skills/tree/main/skills, meaning required external code is fetched and executed during runtime.
