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

• Third-party content exposure detected (high risk: 0.80). The skill includes explicit runtime fetches of open/public content (e.g., calculate-metadata's example fetch(props.dataUrl), lottie.md's fetch of a remote Lottie JSON, and multiple rules that accept arbitrary remote URLs for images/videos/subtitles), and those fetched, untrusted payloads are parsed and used to set composition props, durations, or rendering inputs—allowing third-party content to materially change agent behavior.
