The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Third-party content exposure detected (high risk: 0.90). The SKILL.md explicitly includes code that runs audits against arbitrary URLs (the Lighthouse runAudit(url) function and web-vitals snippets), so the agent would fetch and interpret open/public web pages whose untrusted content could influence its actions.
