Security checks for vulnerabilities and agentic risk

Overview

The skill’s local development checks fit its purpose, though its test helper can overwrite an existing project file.

Run verification on a trusted project or disposable copy. Ensure the project has no existing verify_probe.gd, because the helper overwrites and deletes that filename. Checks marked as needing XR still require testing on suitable hardware.

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

Chaining Abuse

High
Category
Tool Misuse
Confidence
75% confidence
Finding

Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.

Skill declares no tool scope ('permissions' or 'allowed-tools') but code capabilities were detected: file_write.

Confidence

Finding

Without declared permissions the skill's intent is opaque and cannot be validated.
