Security audit

Agent DX CLI

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent CLI review and refactoring guide with scoped references and no evidence of hidden execution, persistence, or data exfiltration.

Install this skill if you want structured help reviewing or improving agent-facing CLIs. Expect it to read CLI help, schemas, code, and test outputs you authorize; use isolated fixtures for business-effect tests and keep real credentials scoped and out of logs.

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
