Server Health Agent

Security checks for vulnerabilities and agentic risk

Overview

This skill transparently gathers read-only server health metrics and does not show hidden, destructive, or unrelated behavior.

Install this only where you are comfortable allowing a skill to read basic host resource metrics and Docker container names/status. No evidence showed modification, persistence, credential access, or data export.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding

The README suggests activating the skill with "Check server health," which is a broad everyday phrase rather than a narrowly scoped invocation. Without clearer trigger constraints or exclusion examples, this could overlap with general conversation and cause unintended skill activation.
