data-cleaning

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed data-cleaning integration that uploads user-selected CSV/XLSX files to its service only for previewed and confirmed cleaning actions.

Install this only if you are comfortable configuring an AI Skills API key and sending selected CSV/XLSX files to the provider for processing. Review previews carefully before confirming execution, and prefer the product-specific API key if you want to limit credential reuse across skills.

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

Confidence
97% confidence
Finding

The manifest description and the full SKILL.md content require Chinese comprehension, which effectively forces a specific language/locale on users and agents. The file does not state that Chinese is optional, nor does it offer an alternative language or a user opt-in mechanism.

Finding

This reference file presents all operational instructions in Chinese and does not indicate that the user may choose another language or that the skill is intentionally limited to a Chinese-language audience. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation.
