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

• Third-party content exposure detected (high risk: 0.90). The skill's SKILL.md explicitly instructs the agent to fetch and extract content from arbitrary URLs using WebFetch ("If the user provides a URL..." in Step 1) and to verify external links via WebFetch (Step 6), meaning the agent will ingest untrusted public web content and use it to drive SEO checks and remediation actions.
