Skills Updater

Security checks across malware telemetry and agentic risk

Overview

This is a disclosed OpenClaw skill updater that can change installed skills, but its behavior matches its purpose and is user-triggered.

Use --dry-run before --auto because this tool can update many installed skills and change future agent behavior. Review the ClawHub source of updates, keep or delete Desktop backups according to your privacy needs, and remove old memory reports if you do not want update history retained.

Finding
The skill explicitly documents creating persistent backups of all skills under a user-accessible Desktop path, which can retain prior code, configuration, and potentially sensitive embedded data indefinitely. Even though backups are framed as a safety feature, persistent copies increase the attack surface by leaving recoverable historical artifacts outside the primary managed location, especially if permissions, workstation sharing, cloud desktop sync, or later compromise expose that folder.
