Security audit

Security checks for vulnerabilities and agentic risk

Overview

This is a clearly scoped Chinese classical-poetry skill with disclosed local study records and optional limited lookups; I found no hidden or destructive behavior.

Before installing, understand that the skill can keep local poetry preferences and study progress if you consent, and it may make optional poem or weather lookups unless you set online:false or say not to use the network. Use the built-in stop, inspect, delete, or no-persistence options if you do not want records kept.

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
Category
Not specified by scanner
Confidence
93% confidence
Finding

The README states "Language scope: Chinese-only by design" and says no multilingual variant exists or is planned. This is a natural-language locale restriction, and the file does not present it as an optional user choice or explicit opt-in.

Data Exfiltration

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The file explicitly states a Chinese-only language scope, which can cause the skill to refuse or constrain responses based on language rather than user need or system policy. In an agent setting, this can reduce accessibility, create unfair output restrictions, and override user expectations if no opt-in or business necessity is documented.
