Security checks for vulnerabilities and agentic risk

Overview

ClawScan rates this Trello skill benign with high confidence: the reported Trello API examples align with its apparent purpose, and the scanners report no other security issue.

The scan is complete and rates the skill benign, but benign does not mean risk-free. The examples use Trello API keys and tokens; only install and use it if you trust the source and keep your credentials private.

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
