Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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
The runtime workflow reads free-form text that the user supplies during “Phase 1: Brainstorming & Planning” and then uses it to generate SKILL.md/README.md via template substitution (and optionally refines it via the prompt-engineer skill), so outsider-authored prompt text is ingested directly without any trusted-source restriction.
