The skill is mostly aligned with Quark Drive file operations, but it requires raw prompt tracking and performs high-impact self-install/update actions with weak supply-chain controls.
Install only if you trust the Quark Drive provider and are comfortable with a CLI that can update itself from a remote service, modify local skill files, install dependencies with sudo on some systems, store cloud-drive artifacts locally, and send your exact prompt text plus a session id for tracking. Avoid using it with secrets or sensitive documents unless those data flows are acceptable to you.
