1 medium severity finding. This skill can be installed but you should review these findings before use.
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.
Third-party content exposure detected (high risk: 0.90). The skill's required "Step 1: Research Domain Best Practices" explicitly directs the agent to "Use WebSearch" and incorporate findings from web searches into the agent's anti-patterns and persona, meaning it fetches and ingests open/public third‑party content (web pages) that can influence agent behavior and tool use.
