CLI Proxy Troubleshooting

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only troubleshooting skill for a CLI proxy, with no hidden execution, persistence, or credential collection behavior found.

Install this if you want Chinese-language troubleshooting guidance for codex-api-proxy. When following it, use your own proxy URL, keep API keys and auth file contents private, and redact logs before sharing them.

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
