High Risk

Automated Linux server patching and Docker container updates. Use when the user asks to update, patch, or upgrade Linux servers, apply security updates, update Docker containers, check for system updates, or manage server maintenance across multiple hosts. Supports Ubuntu, Debian, RHEL, AlmaLinux, Rocky Linux, CentOS, Amazon Linux, and SUSE. Includes PatchMon integration for automatic host detection and intelligent Docker handling.

🔒 Containment

Level: maximum

Required:

SANDBOX_CONTAINER: Code execution capability

Recommended:

LOG_ACTIONS: Audit trail for all actions

⚡ Risks

SSH key access patterns in: SKILL.md, README.md high

Mitigation: Verify legitimate need for SSH access. Consider sandboxing.

Unauthorized tool use: TOOL_ABUSE_SYSTEM_PACKAGE_INSTALL, TOOL_ABUSE_SYSTEM_MODIFICATION, INSTRUCTED_BINARY_INSTALL, MCP_SYS_CRITICAL_ACCESS, INSTRUCTED_GIT_CLONE_AND_BUILD critical

Mitigation: Use user-level installs without sudo

Command injection risk: TIRITH_INSECURE_TLS, COMMAND_INJECTION_USER_INPUT high

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality
