Stablecoin Use Check

Security checks for vulnerabilities and agentic risk

Overview

This is a prompt-only stablecoin decision guide with no evidence of file access, persistence, network use, or hidden behavior.

Before installing, treat the output as general decision support rather than financial advice. The skill does not appear to access accounts or recommend specific platforms, but users should independently verify stablecoin, platform, regulatory, and counterparty risks before committing funds.

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

The declared purpose is a user-facing stablecoin evaluation guide with no permissions and prompt-only behavior. The actual code chunk does not implement or evidence stablecoin guidance; instead, it tests that a handler resists local file access via a path-like skill_name input and returns a safe response. That is a materially different purpose focused on filesystem access/security behavior, which is undeclared and unrelated to the stated skill description.
