Four Layer Memory

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed memory-organization guide with no bundled executable code, network access, hidden behavior, or automatic persistence mechanism.

Install only if you want a Chinese-language memory-organization workflow. Treat the memory folders as potentially sensitive because they may accumulate personal preferences and identity notes, and run the suggested Python commands only after confirming the referenced local script is present and trusted.

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

The manifest description and several section contents are written in Chinese with no indication that the user can choose another language or that the skill is intended only for a Chinese-speaking context. This creates a natural-language locale policy issue because it implicitly enforces a specific language without opt-in.
