W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
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.
Why it was flagged
Third-party content exposure detected (high risk: 0.80). The skill includes Puppeteer automation that navigates to and evaluates arbitrary webpages (see references/compression-monitoring.md: measurePerformance(url) with page.goto(url) and page.evaluate), which fetches untrusted third-party content and reads/interprets it as part of the measurement workflow.
