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

• Third-party content exposure detected (low risk: 0.10). The workflow fetches outsider-authored free text from GitHub changelog/README files by WebFetch using URLs derived from the target gem’s repo (e.g., releases/CHANGELOG/HISTORY/NEWS pages), then extracts and summarizes the release contents.

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

• Potentially malicious external URL detected (high risk: 0.80). The skill's runtime workflow explicitly fetches changelogs from URLs such as https://github.com/OWNER/REPO/releases and injects that fetched content to extract changes and generate upgrade guidance, so external content fetched at runtime can directly control the agent's prompts and analysis.
