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: 0.90). This skill explicitly requires a "page URL" as input and instructs the agent to "Render the page" and "View the rendered HTML" (SKILL.md Workflow steps 2–3), meaning it will fetch and ingest arbitrary public web pages (untrusted third-party content) that can materially influence the agent's audit actions and outputs.
