Codex Harness Engineering

Security checks for vulnerabilities and agentic risk

Overview

This skill is a visible Chinese-language guidance document for Codex engineering practices and does not contain hidden execution, credential access, persistence, or destructive behavior.

Install this only if Chinese-language workflow guidance is suitable for your team. The skill may encourage Codex to create or update repository documentation, lint rules, and PRs, so use normal review controls for generated 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

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The file’s description forces a specific language presentation, and the rest of the skill content is likewise entirely in Chinese. Under the policy, language constraints should either provide user opt-in/choice or be clearly justified as region-specific; neither appears here.
Content: No source excerpt is available for this finding.
