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

The workflow instructs the agent to fetch and analyze public web pages, social media feeds (Bluesky, Twitter), and DNS/WHOIS records during OSINT lookups, where external sources can contain arbitrary outsider-authored text.
