Risk Level: MEDIUM
Full Analysis

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

  • Third-party content exposure detected (low risk: 0.10). The required workflow uses the substack-reader-pp-cli tool to archive, read, and search external Substack publications and posts, ingesting outsider-authored article text into the agent context.

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 an external binary at runtime via npm from @mvanhorn/printing-press-library or via go install from a GitHub repository (github.com/mvanhorn/printing-press-library/...), which constitutes an unofficial operational dependency.
