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.md explicitly instructs the agent to fetch and read public web documentation (e.g., https://modelcontextprotocol.io/sitemap.xml and raw GitHub URLs such as https://raw.githubusercontent.com/modelcontextprotocol/python-sdk/main/README.md, and to "use web search and web fetch as needed"), so the agent will ingest open/public third‑party content that can influence tool design and subsequent actions.
