Security checks for vulnerabilities and agentic risk

Overview

This skill is an offline Xiaohongshu post-writing helper with no evident code execution, data access, persistence, or hidden behavior.

Install this if you want Chinese-style Xiaohongshu/REDnote content generation. If you need English, bilingual, or another locale, tell the agent that when invoking the skill.

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

Natural-Language Policy Violations

Finding

The skill is explicitly designed to produce Xiaohongshu content and its instructions are entirely Chinese-centric, which can override a user's preferred language if the agent invokes it without checking. This creates a user-control and policy-alignment issue rather than a direct security exploit, but it can still cause misleading or unusable output for non-Chinese-speaking users.

Natural-Language Policy Violations

Confidence
94% confidence
Finding

The entire skill is written as a Chinese copywriting formula library for producing 小红书-style content, and it does not indicate that language selection is optional or user-driven. Under the language/locale policy, forcing a specific language without opt-in is a natural-language policy concern.

Finding

This markdown file presents all instructions and style definitions exclusively in Chinese, which can amount to a language policy violation when users are not given an explicit language or locale option. The file does not indicate that the skill is intentionally region-specific or that Chinese output is optional.

Finding

This markdown file contains user-facing instructions exclusively in Chinese, and there is no indication that the skill is region-specific or that users can opt into another language. Under the policy rule for natural-language violations, forcing a specific language without user choice can be a locale-policy issue.
