Tianshu Mistake Sheet

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple Chinese-language Markdown mistake-sheet generator with no hidden persistence, network use, or credential access.

Install this if you want a Chinese-language command-line helper for Markdown mistake-sheet tables. Be aware that --file reads whichever local file path you provide and prints parsed content to the terminal.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Natural-Language Policy Violations

Finding

This JavaScript file contains multiple user-facing strings in Chinese, including error and usage messages, with no indication that the skill is intended only for Chinese-speaking users or that another language option is available. That creates a natural-language policy concern because the skill effectively forces a specific language without user opt-in.

Finding

The tagline is presented only in Chinese while the rest of the manifest includes English fields, which can amount to an implicit language constraint for users reading the skill metadata. The file does not indicate that the user can choose a preferred language or that the Chinese-only text is intentional for a specific locale.
