Security audit

multiplication calculation

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple multiplication teaching/calculation aid with no hidden access, persistence, network use, or sensitive data handling found.

Install this if Chinese-language multiplication help is acceptable. The bundled script is narrow and local, but users who need English or multilingual instructions may find the documentation unclear.

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

Finding
This markdown file contains the skill’s user-facing instructions almost exclusively in Chinese, while not stating that the skill is region-specific or that users may choose another language. Under the natural-language policy rule, forcing a specific language without user opt-in is a locale-policy concern.
