Security checks for vulnerabilities and agentic risk

Overview

The skill received a benign verdict with high confidence: the scanner findings were low probability and considered expected for its stated purpose, and the available checks found no executable scripts.

The verdict is benign, not a guarantee of zero risk. Skillspector scanned the sole Markdown component completely and reported two low-probability external-transmission matches that it did not confirm as exfiltration. Consider whether you are comfortable using the Notion API and supplying a Notion token.

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
