Mkdir Tool

Security checks for vulnerabilities and agentic risk

Overview

This is a simple directory-creation skill whose filesystem writes are disclosed and aligned with its purpose.

Install this as a basic mkdir helper only if you are comfortable with it creating directories at paths you or the agent provide. Review requested paths before use, especially absolute paths or locations outside the current project.

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 skill describes functionality that creates directories, which is a file-system write capability, but it does not declare any explicit tool scope such as permissions or allowed-tools. That mismatch weakens policy enforcement and reviewability because an agent may be granted or invoke write-like behavior without a clearly documented authorization boundary.
