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

• Third-party content exposure detected (high risk: 0.80). The SKILL.md explicitly requires testing and verifying external links and landing pages (e.g., "Every link tested and resolves to correct destination", "Primary CTA link works and lands on correct page", "View-in-browser link present and working") and using external tools ("Spam score tested (mail-tester.com or equivalent)"), which requires fetching and interpreting arbitrary public web pages and third‑party service output.
