This video-generation skill mostly does what it says, but it includes an unnecessary automatic file-opening step that can invoke the shell on macOS with a user-controlled download path.
Review before installing. Use only prompts and images you are comfortable sending to Volcengine/ByteDance, use a scoped Ark API key where possible, choose a non-sensitive output directory, and avoid unusual download paths on macOS until the auto-open os.system behavior is removed or replaced with a non-shell implementation. VirusTotal was still pending, so this verdict is based on artifact review and scanner context rather than antivirus confirmation.
