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's references/examples.md includes an "External API Call" example that takes a user-provided URL and uses reqwest::blocking::get(&url) to fetch and parse arbitrary HTTP JSON responses (and SKILL.md explicitly points to these examples), which is a clear ingestion and interpretation of untrusted third-party content that can materially influence plugin behavior.
