Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese literary style-writing prompt skill with no code, privileged access, persistence, or hidden behavior evident.

Install this if you want a Chinese-language literary style assistant. Be aware it may respond in Chinese and may activate on broad author-style requests; no local data access, command execution, credentials, or persistent changes were evident in the artifact.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Natural-Language Policy Violations

Confidence
84% confidence
Finding

The skill metadata and behavior are entirely Chinese-oriented without stating fallback behavior or requiring user opt-in for language selection. In multilingual environments this can override user expectations and produce responses in Chinese even when the surrounding conversation is in another language, reducing usability and potentially causing miscommunication.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The trigger list includes broad phrases such as '按某某作家风格写' and other style-centric cues that can activate the skill with minimal constraint. This can cause unintended routing or invocation in loosely related conversations, leading to incorrect behavior, surprise language/style transformation, or policy bypass of more specific skills through overmatching.
