Security checks for vulnerabilities and agentic risk

Overview

This skill is a small local resource-status helper with no evidence of network access, persistence, credential handling, or destructive behavior.

Install only if Chinese-language documentation and output are acceptable. The script can reveal basic local system resource details when run, but the reviewed artifact does not show network transmission, persistence, credential use, or destructive actions.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Medium

Confidence
95% confidence
Finding

The file’s natural-language instructions and descriptions are exclusively in Chinese, and there is no indication that users may choose another language or that the skill is intended only for a Chinese-speaking context. This can violate language/locale policy when a skill forces a specific language without user opt-in.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The file’s natural-language descriptions are written in Chinese, including the primary title and user-facing recommendation strings elsewhere in the file, with no indication that the user can choose another language. This creates a locale-policy issue because the skill appears to enforce a specific language without opt-in or justification.
