Security checks for vulnerabilities and agentic risk

Overview

ClawScan rates this skill benign with high confidence: the scanners report Trello API examples and no AIG findings, while treating the repeated external transmission alerts as expected for the skill’s stated purpose.

The scanners report a benign verdict with high confidence and complete coverage of the one Markdown component. Before installing, consider that the skill’s examples send requests to Trello’s API and use key and token parameters; make sure you are comfortable connecting it to your Trello account and protect your credentials. Benign does not mean risk-free.

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
