English Reading Analyzer

Security checks for vulnerabilities and agentic risk

Overview

This is a Chinese-language English reading study skill with no code execution, credential use, persistence, or hidden data access.

Install this if you want Chinese-language help analyzing English reading passages. Be aware that broad trigger phrases may invoke it for general sentence-analysis or reading-comprehension requests, so users who prefer another language or a different tutoring style may need to clarify their intent.

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 README presents the skill entirely in Chinese and does not indicate any language negotiation or fallback behavior, which can effectively force operation in Chinese regardless of user preference. While not a direct code-execution risk, this can create usability and trust issues, especially if the skill is invoked for users expecting another language, leading to misunderstanding or incorrect educational output.

Vague Triggers

Confidence

Finding

The trigger phrases are broad, generic educational terms such as '分析句子' and '阅读理解' that can overlap with many ordinary user requests unrelated to this specific skill. This can cause unintended activation, routing users into this skill when they did not request it, which may reduce reliability, override user expectations, or interfere with safer or more appropriate skills.

Finding

The trigger phrases are broad and include common study-related requests such as analyzing sentences, reading comprehension, and understanding English sentences. This can cause the skill to activate in many ordinary conversations, increasing the chance of unintended routing, prompt interference, or overshadowing more appropriate skills.
