Compose Methods

Security checks for vulnerabilities and agentic risk

Overview

This is a content-structuring methodology skill with disclosed user-choice workflows and no executable code, persistence, credential use, or hidden behavior.

Installers should understand this skill may appear for many structured writing tasks and is primarily Chinese-language. It is reasonable to install if you want a generic content-composition workflow, but prefer more specialized skills for regulated, technical, legal, medical, or other high-stakes work.

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

Vague Triggers

Confidence

Finding

The skill is designed to trigger for a very broad class of requests, including essentially any request for structured output when no method is specified. That can cause it to preempt more domain-specific or safer skills, leading the agent to apply generic content-generation workflows in contexts where specialized constraints, safety rules, or expertise are required.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The natural-language instructions and user-facing interaction template are entirely in Chinese, but the file does not state that the skill is China-specific or that users may choose another language. This can amount to a language/locale policy issue because it implicitly forces one language without opt-in.
