CN Daily Tools 中文日常工具

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese daily-utilities skill with no executable code, install hooks, persistence, credential handling, or hidden behavior.

Install this if you want Chinese-language daily utility prompts. Be aware that accurate weather, exchange rates, news, and package tracking depend on whatever live sources or tools the agent uses at runtime, and the skill presents Chinese as the default interaction language.

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
Confidence
94% confidence
Finding
The description says the skill is for Chinese users and specifically to use it when users need results 'in Chinese,' which imposes a language constraint. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale limitation is clearly justified as region-specific.

Natural-Language Policy Violations

Medium
Confidence
90% confidence
Finding
The phrase '纯中文交互' communicates that the skill operates only in Chinese. Because the file does not offer an alternative language option or explicit user choice, this appears to violate the language/locale policy for natural-language content.
