Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward GitHub repository analysis helper with no executable payload, persistence, or hidden high-impact behavior.

Before installing, expect this skill to read repository metadata and key source/configuration files for repos you ask it to analyze. Use it on repositories you are comfortable exposing to the agent's available tools, especially if the target repository is private or contains sensitive configuration examples.

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
