Gemini Extension Authoring

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

• Potentially malicious external URL detected (high risk: 0.80). The MAINTENANCE.md instructs the agent at runtime to crawl and fetch pages starting at https://geminicli.com/docs/extensions/ (and related geminicli.com docs URLs) and to use that fetched documentation to update SKILL.md and schemas, which means external content will be fetched at runtime and directly control the agent's update instructions.
