Security checks for vulnerabilities and agentic risk

Overview

This skill is a Chinese-language DNS troubleshooting guide that uses standard dig-based diagnostics and does not show hidden, destructive, persistent, or exfiltrating behavior.

Install only if you are comfortable using a Chinese-language DNS guidance skill. Review suggested DNS changes before applying them in your DNS provider console, and be aware that the listed write permission and generic API-key/callback fields are not clearly needed for the documented dig-based workflow.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • 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
90% confidence
Finding

The skill's display name, summaries, and description are written exclusively in Chinese, and the document provides no indication that users may choose another language or locale. Per the policy, forcing a specific language without user opt-in is a natural-language policy violation.

Intent-Code Divergence

Confidence
88% confidence
Finding

At L010 the description says the skill provides '自动检测能力' (automatic detection capability), which implies active checking behavior. However, the documented behavior throughout the file is mainly instructional use of dig commands and recommendations, and L211 explicitly says it cannot directly modify DNS records; this creates an intent-level mismatch between the advertised autonomous capability and the documented/manual nature of the skill.

Intent-Code Divergence

Confidence
91% confidence
Finding

Lines L083-L097 repeatedly describe automatic parameter parsing and task-queue dispatching for TTL/SPF/DMARC functions. In this skill file, the actual content is procedural guidance, examples, and command references rather than any implementation of queue dispatch or structured automation, so the documentation overstates and contradicts what the skill actually defines.
