代码单元测试

Security checks for vulnerabilities and agentic risk

Overview

This skill only guides an agent to compare branch changes and produce simulated unit-test case tables; I found no hidden execution, persistence, or data-exfiltration behavior.

Installers should understand that the skill will read repository status, diffs, and relevant changed code to produce simulated unit-test tables. It should be used in repositories where that code visibility is acceptable, and users can request another output language if Chinese is not preferred.

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

Low
Category

Confidence
96% confidence
Finding

The instruction says to 'Report in Chinese unless the user requests another language,' which imposes a default language choice rather than first offering the user a language/locale option. This matches the policy-violation category for forcing a specific language without user opt-in.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
84% confidence
Finding

The file presents the skill name in Chinese while the short description and default prompt are in English, but there is no indication that the user can choose or opt into a language/locale. This can violate a language policy requiring explicit user choice rather than silently imposing mixed-language behavior.
