MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (medium risk: 0.30). The Google Calendar integration allows listing and reading calendar events which can contain outsider-authored text descriptions and invitee messages.

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

• Potentially malicious external URL detected (medium risk: 0.30). The skill instructs the agent to install and execute a third-party CLI tool from npm (@membranehq/cli), which introduces an unverifiable external operational dependency with unofficial or community provenance.
