Security audit

Yorkshire Puppy Care

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Chinese-language Yorkie care assistant that asks for pet-care details and uses web search for current information, with no evidence of hidden execution, persistence, exfiltration, or unsafe authority.

Install only if you want a Chinese-language pet-care assistant. Share only pet and household details you are comfortable providing, expect search queries to be sent to the configured web-search provider, and use a veterinarian for urgent or serious health symptoms.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • 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
Findings (4)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The manifest sets language: zh-CN, and the skill description is entirely presented in Chinese without stating that users may choose another language. The policy requires flagging language or locale constraints when a specific language is imposed without explicit user opt-in or clear region-specific justification.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The instructions explicitly require prioritizing Chinese search keywords and prescribe a Chinese example closing line for every reply, which imposes a language/locale preference without user opt-in. Under the policy, language constraints should be optional, user-selected, or clearly justified as region-specific.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The manifest explicitly sets the skill language to "zh-CN", which indicates the skill is intended to operate in a specific language/locale. There is no accompanying text offering a language choice or documenting a justified region-specific constraint, so this appears to violate the language/locale policy requirement.

Missing User Warnings

Category
Not specified by scanner
Confidence
77% confidence
Finding

This markdown skill description instructs the assistant to gather structured information such as feeding schedule, medical history, deworming, and vaccination timing immediately at first contact. While not highly sensitive like credentials, it is still user-associated household and animal health information, and the description provides no disclosure or caution about requesting, retaining, or using that data.
