Security audit

Jail

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small local reference helper that prints generic sysops guidance and does not show credential access, network activity, persistence, or destructive behavior.

This appears safe to install as a lightweight reference skill. Users should treat it as generic checklist-style guidance rather than authoritative jail documentation, and be aware it may activate for broad sysops mentions of 'jail'.

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 description and 'When to Use' section say to use the skill when 'working with jail in sysops contexts' and for general needs like troubleshooting or needing a checklist, but they do not define clear trigger phrases, scope boundaries, or negative examples. In a markdown skill description, this ambiguity can cause the skill to be invoked in loosely related conversations where 'jail' is mentioned without the user actually wanting this reference tool.
