Security audit

go-zeroentropy

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Go helper skill for using an unofficial ZeroEntropy API client, with external API use and account mutations disclosed and tied to the stated purpose.

Before installing, confirm you trust the third-party Go module and the ZeroEntropy account/region you intend to use. Keep `ZEROENTROPY_API_KEY` out of source control and logs, and only run collection, document, organization, or API-key mutations when you explicitly want those account changes.

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
