Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward threading and concurrency help skill with sample code and no hidden access, persistence, or privileged behavior.

Before installing, note that the README is Chinese-only and the activation wording is broad, so the skill may appear for general concurrency questions. The inspected artifacts do not request sensitive access or perform system changes.

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
Confidence
92% confidence
Finding
The skill description is written as a Chinese-only user-facing README and does not indicate that users may choose another language or that the skill is intended only for a Chinese-speaking or region-specific audience. This can violate language/locale policy when a skill implicitly forces a specific language without opt-in.

Vague Triggers

Low
Confidence
93% confidence
Finding
The skill description and usage guidance say to use the skill when the user asks about 'threads, threading, concurrency, race conditions, locks, mutex, thread pool, or parallel execution' and 'threads or concurrency' without narrowing scope or giving exclusion examples. Terms like 'concurrency' and 'parallel execution' are broad and may overlap with general software-design discussions, making activation boundaries unclear.
