Academic Historian

Security checks for vulnerabilities and agentic risk

Overview

This is a single Markdown historian-persona skill with no code execution, persistence, credential access, or hidden high-impact behavior.

Safe to install for users who want Chinese-language historical research assistance. Users who prefer another language may need to ask explicitly for responses in that language.

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 skill content strongly constrains the interaction to Chinese by making all role, workflow, and deliverable instructions Chinese-only, without offering a user-language choice or fallback. This can override user preference, reduce accessibility, and cause the agent to ignore or mishandle requests in other languages, which is a legitimate prompt-quality and policy-control issue even if it is not overtly malicious.
