Security checks for vulnerabilities and agentic risk

Overview

Scanners rated this skill benign with high confidence: they found no AIG issues and treated one documentation URL flag as expected, though benign does not mean risk-free.

The verdict is benign with high confidence, and Skillspector reports complete coverage of the single component. Consider whether the documented API destination is relevant to your use before installing; the scan does not establish that the skill transmits data.

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
