Security checks for vulnerabilities and agentic risk

Overview

This skill is a self-contained reference helper that prints documentation and does not show evidence of hidden access, network use, persistence, or credential handling.

This appears safe to install as a reference/documentation skill. Be aware that one command name in the cheatsheet is inaccurate, so use the listed 'debugging' command for troubleshooting content.

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

Credential Access

Category
Privilege Escalation
Confidence
70% confidence
Finding

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

Finding

The cheatsheet says an essential command is 'troubleshooting', but the dispatcher only implements 'debugging' along with the other listed commands. This is an active contradiction in the skill's own inline reference content, which can mislead users about the available interface.
