MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

  • Third-party content exposure detected (high risk: 0.90). The skill's Phase 1 instructions explicitly require fetching and reading public web resources (e.g., "Use WebFetch to load: https://modelcontextprotocol.io/llms-full.txt", the GitHub raw README URLs, and "use web search and the WebFetch tool as needed" in 1.5), so the agent will ingest untrusted, user-generated/open web content that can influence its subsequent tool design and behavior.
