Xueersi Classical Poetry Assistant

Security checks for vulnerabilities and agentic risk

Overview

This is a simple educational poetry assistant with no executable code, hidden access, or persistence behavior.

Install this if you want a Chinese classical poetry tutoring aid. Expect it to focus on Chinese poetry and student-friendly explanations; users who need another language should explicitly ask for that language.

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
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Finding

This markdown file describes the skill's purpose and modes but does not specify how or when the skill should be invoked, nor does it provide bounded trigger phrases or exclusion conditions. Without clear trigger scope, a router could match broad everyday requests about poetry, memorization, or questions too aggressively.

Natural-Language Policy Violations

Medium
Category

Confidence
78% confidence
Finding

The description centers the assistant on Chinese classical poetry for Chinese K-12 students and includes bilingual branding plus mode behavior like modern Chinese paraphrase, but it does not state that language choice is optional. This can create a locale or language policy issue if the skill defaults users into Chinese output without offering a choice.
