Security checks for vulnerabilities and agentic risk

Overview

This is a market-data helper that uses disclosed public web/API sources and does not install code, run commands, persist itself, or handle transactions.

Install only if you want an agent to perform live market lookups using public web and API sources. Avoid pasting wallet seed phrases, exchange credentials, or private account exports; treat portfolio recommendations as informational and execute trades only through your own trusted wallet or brokerage.

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 skill description is broad enough to match many common finance-related requests, which can cause the agent to invoke this skill in situations beyond narrow market-data retrieval. Overbroad triggering increases the attack surface for prompt/instruction conflicts and may route sensitive or unrelated financial conversations into a tool-using skill unnecessarily.
