Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese-language content generation skill for Xiaohongshu posts, with no code execution, credential use, uploads, or persistence found.

Before installing, consider that this skill is tailored to Chinese Xiaohongshu marketing copy and includes broad activation keywords plus a mention of a paid Pro version. Do not provide sensitive personal, medical, legal, financial, or credential information in prompts, and review generated claims before publishing.

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

Findings (4)

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 88% confidence
Finding: The metadata and description present the skill as Chinese-only without offering any language choice, which can force behavior that does not align with the user's preferred language. This is mainly a safety and usability issue: it may cause the agent to respond in an unexpected language, reducing transparency and increasing the risk of misunderstanding in sensitive or regulated content areas.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The trigger keywords are broad enough to match ordinary conversation about Xiaohongshu notes, titles, reviews, or guides, which can cause the skill to activate when the user did not explicitly request it. This is not directly dangerous in a code-execution sense, but it can lead to unintended routing, user confusion, and inappropriate content generation in contexts where the skill is not relevant.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 88% confidence
Finding: The skill name is entirely in Chinese ("小红书爆款笔记生成器"), which indicates a language-specific user experience, but this manifest provides no indication that the language choice is optional or limited to a justified region-specific context. Under the policy, forcing a specific language without opt-in can be a natural-language policy violation.
Content: No source excerpt is available for this finding.

Vague Triggers

Low

Category: Not specified by scanner
Confidence: 86% confidence
Finding: The trigger phrase “爆款笔记” is generic marketing language and can appear in ordinary discussion, making accidental activation plausible. In a skill system, ambiguous triggers increase the chance of the wrong tool being selected, which can override user expectations or insert generated promotional-style output where it was not requested.
