Security checks for vulnerabilities and agentic risk

Overview

This skill appears to do what it says: collect PC hardware details for a Xianyu resale estimate and generate local selling materials, with minor privacy cleanup caveats.

Install this only if you are comfortable letting the agent run a local PowerShell inventory of your PC and create local report/poster files. Consider deleting the temporary pc_config.txt file after use, and review generated listing text before posting so hardware condition and any defects are described accurately.

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

Missing User Warnings

Finding

The skill is explicitly designed to auto-enumerate detailed local hardware information, including CPU, memory, disks, GPU, motherboard, peripherals, network adapters, and OS details, without requiring an explicit consent step or presenting a clear warning before collection. Even if the purpose is legitimate valuation, this gathers sensitive device inventory that can reveal fingerprinting data and operational details that users may not expect to disclose automatically.

Missing User Warnings

Confidence

Finding

The skill instructs writing collected hardware inventory to a temporary file on disk, but does not warn the user that a persistent artifact containing detailed system information will be created. This creates avoidable privacy and forensic exposure because other local users, processes, backups, or diagnostic tooling may access the file before it is deleted, especially since no cleanup step is specified.

Natural-Language Policy Violations

Confidence
95% confidence
Finding

The instructions require a Chinese interface, Chinese marketplace copy, and Chinese poster content, which imposes a specific language/locale by default. There is no indication that the user can opt into another language or choose a locale, so this is a natural-language policy issue under the language-choice rule.

Natural-Language Policy Violations

Confidence
83% confidence
Finding

The entire skill reference is written in Chinese and provides no indication that users may choose another language or that the Chinese-only scope is required for a region-specific purpose. Under the policy rule for language or locale constraints, this can be a natural-language policy violation when no opt-in or justification is present.
