gfonts

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

• Third-party content exposure detected (low risk: 0.10). The gfonts skill’s runtime workflow is a zero-auth terminal CLI that performs Google Fonts search/browse/download, which requires the agent to ingest outsider-free text only when the user supplies the search <query> or similar parameters, not from a monitored third-party text feed or arbitrary outsider-posted content.

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

• Potentially malicious external URL detected (high risk: 0.80). The skill includes a runtime installation command that will fetch and build remote Go code — "go install github.com/mvanhorn/printing-press-library/library/developer-tools/gfonts/cmd/gfonts-pp-cli@latest" — which executes remote code as a required dependency if the CLI is installed at runtime.
