Security checks for vulnerabilities and agentic risk

Overview

This is a text-only brand voice proofreading skill with no hidden code, network use, persistence, or automatic modification behavior.

Installers should expect a Chinese-language brand voice checker. Review the broad trigger terms if accidental activation matters in your environment, and do not treat its risk-word hints as legal compliance advice.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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
88% confidence
Finding

The manifest trigger list contains short, generic phrases such as '品牌语气', '语气校对', and 'brand voice' without contextual constraints. In an agent routing system, these broad triggers can over-match benign user text, causing accidental skill activation and misrouting of tasks or disclosure of user content into an unnecessary transformation workflow.

Vague Triggers

Medium

Confidence
87% confidence
Finding

The usage examples include broad natural-language phrases like '这段是不是不太像我们', which can match ordinary conversation outside a clear proofreading request. This can cause unintended invocation of the skill and lead the agent to enter a constrained rewriting/auditing mode when the user may have meant a general discussion instead.

Natural-Language Policy Violations

Medium

Confidence
92% confidence
Finding

This markdown file presents all instructions and policy guidance exclusively in Chinese, and there is no natural-language indication that users may choose another language or that the content is intentionally limited to a Chinese-speaking context. Under the policy rule, forcing a specific language without user opt-in is a natural-language policy violation.

Natural-Language Policy Violations

Confidence

Finding

The template headings, instructions, and placeholders are all in Chinese, which constitutes a language-specific constraint in the skill content. Under the policy, forcing a specific language without user opt-in or an explicit justified regional scope is a natural-language policy violation.

Confidence
76% confidence
Finding

The statement “不校对非中文语种的细微语感” sets a language capability constraint that favors Chinese without offering a user choice or an explicit locale-specific justification. This can be read as a language policy limitation rather than a documented opt-in preference.
