Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese-language communication coaching skill with no code, network access, persistence, or privileged behavior.

Install this if you want Chinese-language coaching for presentations, explanations, and challenge-style review. Be aware that generic triggers like asking how to say or explain something may route ordinary Chinese phrasing questions to this skill.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • 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

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The entire skill description, headings, and trigger phrases are written in Chinese, implying the skill operates in Chinese by default, but there is no indication that users may choose another language. Under the policy, forcing a specific language without user opt-in is a natural-language policy concern unless the locale restriction is clearly documented and justified.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger list contains very broad everyday phrases such as '怎么说', '怎么解释', and '帮我看看这段话怎么说', which are likely to appear in many normal conversations unrelated to this skill. That can cause unintended invocation, routing user content to the wrong skill, and unpredictable behavior or disclosure of sensitive context to an unnecessary tool.

Natural-Language Policy Violations

Confidence
89% confidence
Finding

This markdown file is entirely written in Chinese and presents the pattern guidance only in that language, with no indication that users may choose another language or that the skill is region-specific. Under the language/locale policy rule, a skill that effectively requires a specific language without opt-in can be a natural-language policy concern.
