World Builder

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Chinese-language worldbuilding skill that reads its own references and optionally user-specified character skills to generate new world skill files.

Install this if you want a Chinese-language worldbuilding workflow. Review generated Skill files before enabling them, and only provide character Skill paths you are comfortable having summarized into a shared world model.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger phrases are broad enough to match ordinary discussion about worldbuilding, fictional settings, or general design, which can cause the skill to activate unexpectedly outside the user's intent. In an agent environment, overbroad activation can redirect conversations, consume resources, or cause unintended file reads/writes or workflow execution under the wrong context.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The entire skill exemplar is written as Chinese-only operational content, including headings, input/output schema, and routing logic, with no indication that users may choose another language. Under the policy rule, a skill that effectively requires a specific language without opt-in is a natural-language policy violation unless the locale restriction is explicitly documented and justified.

Natural-Language Policy Violations

Medium

Confidence
93% confidence
Finding

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

Natural-Language Policy Violations

Confidence
90% confidence
Finding

The document title and all operational instructions are written as a fixed Chinese-language methodology, and no line offers an alternative language or user opt-in for locale selection. Under the policy rule, forcing a specific language without user choice is a natural-language locale violation.

Intent-Code Divergence

Confidence
88% confidence
Finding

The documentation says Mode B routes to 'W8 extraction then merge' and later refers to 'W8全域', but the domain inventory only defines W0-W7 and contains no W8 tasks. This is an active contradiction in the skill's own documentation about how character-extraction mode is executed.

Finding

该 markdown 文件的标题、说明和全部任务定义均仅以中文书写,没有说明这是面向特定中文区域/团队的限定文档,也没有提供用户可选择其他语言的机制。按规则,强制单一语言而无用户 opt-in 属于自然语言层面的 locale policy 风险。
