Security checks for vulnerabilities and agentic risk

Overview

This is a Chinese-focused learning coach skill made of instructional Markdown, with no code, credential access, persistence, or hidden high-impact actions.

Install this if you want a Chinese-first learning coach for understanding concepts, preparing for exams, and designing practice. Be aware it may activate on many education-related prompts, and users who prefer another language should specify that language explicitly.

  • 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

Vague Triggers

Medium
Category

Confidence
91% confidence
Finding

The skill description includes very broad trigger phrases such as learning methods, exam prep, review strategy, and concept understanding, which overlap with a large fraction of normal educational queries. This can cause the skill to activate outside its intended scope, leading to inappropriate instruction takeover, prompt-routing confusion, or accidental exposure of internal skill behavior in unrelated conversations.
