Security
1 medium severity finding. This skill can be installed but you should review these findings before use.
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
Yes — Phase 3 ("Research High-Uplift Practices") explicitly instructs the workflow to search and gather public GitHub issues, blog posts, FAQs/wikis and other external documentation and include those references so the agent reads and uses untrusted, user-generated web content to decide which practices to teach (SKILL.md "Finding candidates" and "Gathering references").
