Security checks for vulnerabilities and agentic risk

Overview

ClawScan marked this skill benign: the scanners found no AIG issues and treated one low-probability excessive-agency flag as expected, though the review was partial.

The verdict is benign, but not risk-free. Skillspector’s scan was partial because several local path-like references could not be resolved, so evidence is incomplete; consider that limitation when deciding whether to install.

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

Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
