Chinese Name Pinyin Sort

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward local helper for sorting Chinese names by pinyin, with no hidden access, persistence, or destructive behavior found.

Before installing, note that the helper depends on pypinyin and currently suggests an unpinned pip install if it is missing. Use a virtual environment and pin the dependency version if reproducibility matters.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The manifest description says to use the skill whenever the user needs to sort Chinese names by pinyin, listing several broad phrasings such as '给姓名排序' and '姓名排序'. These phrases are general enough to overlap with ordinary requests and the file does not provide negative examples or explicit limits on when the skill should not activate.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 92% confidence
Finding: This file contains user-facing documentation, argument descriptions, warnings, and output text entirely in Chinese. Under the policy, forcing a specific language without opt-in is a natural-language policy violation unless the locale restriction is explicitly justified or the user is offered a language choice, neither of which appears here.
