Chart Designer Zh

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward Chinese-localized chart design skill with no hidden execution, persistence, credential handling, or destructive behavior found.

Installers should expect a Chinese-language chart design assistant that may read or create spreadsheet/chart files when asked; provide only the data needed for the chart and review generated configurations before using them in reports or applications.

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
92% confidence
Finding
The skill is explicitly labeled with a Chinese locale marker ('-zh') and all descriptive and usage text is written only in Chinese, with no indication that users may choose another language. This can violate language/locale policy when a skill forces a specific language without user opt-in or justification.
