Golden Master

Security checks for vulnerabilities and agentic risk

Overview

This skill is a documentation freshness helper that reads repository files and produces checksum metadata, with no evidence of hidden execution, exfiltration, or privileged persistence.

Install only for repositories where you are comfortable letting the agent read documentation or source files. Review suggested relationships and checksum metadata before asking the agent to add or refresh comments.

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
