Security checks for vulnerabilities and agentic risk

Overview

This is a simple local Chinese-language chat demo that maps numeric input to fixed replies and shows no hidden access, persistence, network use, or privilege-seeking behavior.

Install only if a small Chinese-language terminal chat demo is useful to you. It appears low risk, but users who need English or multilingual behavior should expect to adapt the prompts and responses.

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

Findings (3)

Natural-Language Policy Violations

Medium

Confidence: 95% confidence
Finding: The manifest description and all user-facing instructions are written in Chinese, and the documented responses are fixed Chinese phrases. This imposes a specific language/locale on users without any opt-in, alternative language option, or explanation that the skill is intended only for a Chinese-language context.

Natural-Language Policy Violations

Low

Confidence: 94% confidence
Finding: The docstrings and all user-facing prompts and responses are written only in Chinese, which imposes a specific language on users without any opt-in or alternative. The policy allows locale constraints only when they are explicitly offered as a choice or clearly justified, neither of which appears in this file.

Natural-Language Policy Violations

Low

Confidence: 91% confidence
Finding: The natural-language comments in this file are written only in Chinese, which may impose a language constraint on users or maintainers without offering any language choice or opt-in. The policy requires flagging language or locale constraints when they are not explicitly optional or justified.
