Security checks for vulnerabilities and agentic risk

Overview

This skill only gives instructions for calculating addition problems and does not request unusual access or persistence.

This appears safe to install for simple addition assistance. It is intentionally limited to addition, so users should not expect it to handle broader math beyond extracting numbers and summing them.

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

Finding

This markdown file contains example prompts in Chinese, which can imply the skill expects or privileges a specific language without stating that users may choose their preferred language. Because the file does not clarify multilingual support or user opt-in, it may conflict with language/locale policy expectations.
