Low-risk findings worth noting
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.
This skill’s runtime workflow ingests free text only from user-provided instructions (e.g., “responsiveness check”/URLs to test) to control which specific pages to open and screenshot; it does not read outsider-authored free text from a monitored external feed or arbitrary external content without an explicit selection by the user.
