Jutiku_Quiz_Expert

The skill specification implements expected behavior for converting documents and generating quizzes; it contains no explicit backdoor, exfiltration, or obfuscated malicious code. The main security concerns are operational and supply-chain: the skill recommends auto-installing Python and third-party tooling (markitdown) via system package managers and suggests privileged installs. That behavior increases attack surface and could lead to compromise if a malicious package or compromised registry is used. Recommended mitigations: require explicit informed consent before any installation, prefer preinstalled or vetted tools, use containerized/sandboxed conversion, verify package sources/signatures, and add explicit handling/sanitization of converted content (e.g., strip macros, avoid executing embedded code).
