Data Cleaning and Statistical Analysis Skill

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward data-cleaning and statistical-analysis skill with no hidden execution, persistence, credential use, or unrelated authority.

Installers should treat this as a normal data-analysis skill, but should avoid sharing identifiable clinical or participant data unless they are comfortable having the agent process it in the current environment.

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

Category: Not specified by scanner
Confidence: 84% confidence
Finding: The example user requests are exclusively in Chinese, which implies a language-specific operating context, but the skill does not explicitly state that language choice is optional or that the skill is intended only for Chinese-speaking users. This can create a natural-language policy issue if the skill is interpreted as preferring or requiring a specific language without user opt-in.
