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: 0.90). The SKILL.md explicitly shows content scripts (content/content.js) configured to run on matched pages (example uses "matches": ["<all_urls>"]) and to read DOM content (document.querySelector(...).textContent) and send it to the extension, meaning the skill guides ingesting arbitrary, untrusted web page/user-generated content that can influence extension behavior.
