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

• Potentially malicious external URL detected (high risk: 0.90). The skill's setup explicitly instructs installing and relying on the Nano Banana extension via the URL https://github.com/gemini-cli-extensions/nanobanana, which would fetch and install remote code used at runtime to provide commands that control generation/editing prompts—so the external repo is a required runtime dependency that can execute code and influence agent behavior.
