Cn Whitespace Cleaner

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple Chinese-language whitespace cleaner that only processes user-provided text or files and shows no hidden security behavior.

Install only if Chinese-language instructions are acceptable. When using the file mode, choose the output path carefully because the script writes normalized text to the path you provide and may overwrite that file.

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

Findings (2)

Natural-Language Policy Violations

Medium
Confidence
91% confidence
Finding
The user-facing instructions and feature description are presented exclusively in Chinese, which can effectively force a specific language on users without opt-in. The policy allows locale constraints only when they are clearly documented and justified, which is not present here.

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The file uses Chinese-only natural-language strings in the module docstring, argument descriptions, and user-facing messages. This imposes a specific language on users without any opt-in, fallback, or documented reason that the tool is region-specific, which matches the locale policy violation criteria.
