Caveat verdict

heygen-skills

88
🟢 Trusted
No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

HeyGen video creation skill using the official HeyGen API via MCP or CLI; file access is explicitly scoped to avatar identity files and a local video log, with remote uploads only when user explicitly provides assets — behavior matches stated video generation purpose.

⚠ Flagged for review — coarse, uncorroborated signal, not a confirmed exploit. Review the config yourself before installing.

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.
