What is HostCheck for OpenClaw?
HostCheck is a lightweight, non-intrusive diagnostic skill designed specifically for Openclaw Skills users who want to maintain high availability and security for their deployments. It serves as a comprehensive health monitor that audits system resources, security configurations, and package update statuses without requiring expensive third-party tools.
By providing a centralized view of everything from SSH hardening to disk usage, this skill ensures that developers can catch potential infrastructure issues before they impact running services. It prioritizes a read-only approach, acting as an expert advisor that provides actionable recommendations for host optimization and maintenance.
