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's required workflow (SKILL.md Step 2 and related sections) explicitly instructs the agent to search and ingest public web sources—including GitHub repositories, package registries (npm/PyPI/crates.io), academic papers and other public websites—and then use those findings to generate and apply corrections, which clearly exposes the agent to untrusted third-party content that can influence its actions.
