pp-epa-echo

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

• Third-party content exposure detected (medium risk: 0.30). The skill’s runtime workflow ingests outsider free text passed as part of the user’s question into epa-echo-pp-cli recall "<user's question>" --agent, and that text can flow into the CLI’s candidate/playbook selection logic and subsequent tool invocation.

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

• Potentially malicious external URL detected (high risk: 1.00). The skill includes explicit install-time commands that fetch and execute remote Go modules (e.g., "go install github.com/mvanhorn/printing-press-library/library/other/epa-echo/cmd/epa-echo-pp-cli@latest" and "go install github.com/mvanhorn/printing-press-library/library/other/epa-echo/cmd/epa-echo-pp-mcp@latest"), so at runtime an agent following the install instructions would download and execute remote code required by the skill.
