Security Audit
CriticalMost static matches are benign lexical detections from local video rendering, documentation, and caption themes. However, the skill contains a prompt-injection instruction and several high-risk execution paths involving remote dependencies, generated shell code, and unisolated rendering. Do not auto-install or execute it until the remediation items are addressed. Static review was capped at 400/1432 representative findings; omitted static matches are unconfirmed, so automatic publishing stays disabled until manual review.
