Batch Convert Zh

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese-language batch document conversion skill with expected local file read/write behavior and no hidden code or persistence.

Before installing, understand that this skill is intended for Chinese-language batch document conversion and may process many selected local files. Use explicit source folders, output folders, and target formats, and confirm overwrite behavior when converting sensitive documents such as contracts, resumes, or financial reports.

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: 80% confidence
Finding: The skill name suffix "zh", the fully Chinese description, and all examples indicate a language-specific experience, but the file does not explicitly state that Chinese is required or offer an alternative language option. Under the policy, forcing a specific language without user opt-in is a natural-language policy concern.

Vague Triggers

Medium

Confidence: 88% confidence
Finding: The trigger list uses broad natural-language phrases such as '批量转换文件' and '自动格式转换' without clear activation constraints, which can cause the skill to match ordinary document-help requests unintentionally. In an agent environment, over-broad routing can expose local files to batch processing tools and cause unintended reads/writes across user directories.

Missing User Warnings

Medium

Confidence: 94% confidence
Finding: The skill describes bulk conversion but does not warn users that it may read many local files from folders and write converted outputs back to disk. This can lead to accidental processing of sensitive documents, unexpected data propagation into new formats, and unanticipated filesystem changes when users invoke the skill casually.
