No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

Accesses credentials AND makes external network calls

A clean HeyGen video generation skill that uses the user's own HEYGEN_API_KEY to call documented HeyGen API endpoints; all network calls go to heygen.com for their stated purpose of creating videos.

Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.
