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

• Potentially malicious external URL detected (high risk: 0.90). The guide runs gemini extensions install https://github.com/firebase/agent-skills (references/setup/gemini_cli.md:20), which fetches and installs code from that GitHub repository at runtime so remote code would be executed and is required for the skill setup.
