Fu Shi

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese-language task planning skill that decomposes, plans, and tracks tasks without sensitive access or hidden behavior.

Install this if you are comfortable with a Chinese-language planning helper. It appears low risk: it only provides local task planning logic and does not request sensitive data, credentials, network access, persistence, or broad system permissions.

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

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The natural-language content throughout the skill file is presented only in Chinese, which can force a specific language on users without opt-in. Under the policy, locale or language constraints should either be optional for the user or clearly documented as region-specific and justified.

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The file’s header and all task-detection keywords are written only in Chinese, which means the skill effectively requires Chinese-language inputs to function as intended. There is no user opt-in, alternate locale support, or documentation indicating that this is an intentionally region-specific skill.
