Tianshu Homework Split

Security checks for vulnerabilities and agentic risk

Overview

This skill locally turns student assignment text into a Markdown checklist and does not show hidden network, persistence, credential, or destructive behavior.

Install this if you want a local Chinese-language homework checklist splitter. Review the text you pass in because the tool reads the file path or text you provide and prints extracted tasks, but it does not appear to send data elsewhere or persist anything.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
80% confidence
Finding

The natural-language description and trigger examples are written in Chinese, which effectively constrains intended use to Chinese-speaking users, while the file does not state any optional language support or user choice. Under the policy, language or locale constraints should either be optional or clearly justified.

Natural-Language Policy Violations

Category
Not specified by scanner
Confidence
97% confidence
Finding

This code emits error messages and usage text only in Chinese, and later produces Chinese markdown output as well. That creates a natural-language locale constraint without user opt-in, which matches the policy-violation category for forced language behavior.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
98% confidence
Finding

The generated checklist headings and guidance are always produced in Chinese, with no option to select another language. This is a language-policy issue because the skill forces a specific locale rather than offering user choice or documenting a justified regional scope.
