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

• Potentially malicious external URL detected (high risk: 0.90). The skill mandates at runtime installing and running the external "firebase/agent-skills" package via "npx -y skills add firebase/agent-skills -y" (source: https://github.com/firebase/agent-skills/tree/main/skills), which fetches and executes external agent-skill code that can modify prompts/instructions and is required by the skill.
