Cn Join Lines

Security checks for vulnerabilities and agentic risk

Overview

This is a small local text-formatting skill that joins user-provided lines and does not show hidden access, persistence, network activity, or destructive behavior.

Install only if Chinese-language documentation is acceptable for your workflow. The included promotional links are visible in the README; the tool itself appears limited to local text joining.

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

Low
Confidence
91% confidence
Finding
The markdown content presents the skill description and usage only in Chinese, which effectively forces a specific language for users. Under the stated policy, locale or language constraints should either be optional for the user or explicitly documented as justified.

Natural-Language Policy Violations

Low
Confidence
92% confidence
Finding
The docstrings, argument parser description, and help text are entirely in Chinese, which imposes a specific language on users without any opt-in or indication that the tool is intentionally region-specific. This matches the policy category for language or locale constraints expressed in natural language.
