Security checks for vulnerabilities and agentic risk

Overview

This skill is a generic local reference-docs tool and I found no behavior that reads secrets, uses the network, persists, or changes the system.

Before installing, be aware that the skill is very generic and may not clearly indicate when it should be invoked. Its inspected behavior is limited to printing reference text, with no observed network, credential, file-reading, persistence, or system-changing actions.

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

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Finding

The skill name and description are so generic that they do not clearly communicate the skill's scope or trigger conditions. In an agentic environment, vague metadata can cause incorrect invocation or overbroad selection, which may expose users to irrelevant or unintended skill behavior even if the current content appears documentation-only.
