Security checks for vulnerabilities and agentic risk

Overview

This skill only configures CoinMarketCap market-data lookups for crypto questions, with no bundled code, persistence, local file access, or destructive behavior.

Install this if you want the agent to use CoinMarketCap for crypto-related questions. Be aware it may call CoinMarketCap for broad crypto mentions and may use your CoinMarketCap API quota; review or narrow the trigger wording if you only want explicit market-data requests to invoke it.

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 instructs activation for essentially any crypto-related mention, including cases where the user did not explicitly request external market data. This can cause unnecessary tool invocation, over-collection of third-party data, and behavior that overrides normal user-intent boundaries, increasing the chance of privacy leakage, excessive API usage, or unwanted external calls.
