Security checks for vulnerabilities and agentic risk

Overview

This is a static game-design writing skill that creates a scoped design document and does not request privileged access, persistence, or external execution.

Before installing, confirm you are comfortable with a Chinese-authored design-method skill that writes a game design document into your project. It does not show signs of hidden execution or data exfiltration, but users who need English-only internal instructions may find the reference material less accessible.

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

Vague Triggers

Finding

The default prompt says to use "$game-world-design" to deepen a concept, but the manifest does not define when this skill should or should not activate beyond that single broad instruction. It lacks explicit scope, constraints, or negative examples, which can make invocation behavior ambiguous in a manifest context.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
84% confidence
Finding

Line L04 states that the writing must follow the PRODUCT_BRIEF output language and rating, while the document itself is entirely written as a Chinese-only instruction set with no indication that users may choose another language or locale. This creates a natural-language locale constraint without explicit user opt-in, which matches the language policy violation category.

Confidence
91% confidence
Finding

This markdown file contains user-facing natural-language instructions only in Chinese, and there is no indication that the skill is region-specific or that users can opt into this locale. Per the policy, forcing a specific language without user choice is a natural-language policy violation.

Finding

The entire document is written in Chinese and provides no indication that language selection is optional or that the skill is intended only for a Chinese-speaking audience. Under the policy, forcing a specific language without user opt-in is a natural-language locale violation.
