小红书数据智能助手

• Outcome: Review
• Latest audit: Sep 29, 2026 · 1:45 AM UTC
• Version: 1.1.4

Overview

The skill is a disclosed Xiaohongshu public-data CLI that uses a GUAIKEI API token, sends user-provided keywords or links to guaikei.com, and saves returned results locally.

Install this only if you are comfortable using a third-party GUAIKEI API: your Xiaohongshu keywords or links and API token are used for requests, and returned results are saved as local temp logs. Protect the token and use the tool only for public Xiaohongshu data as documented.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Findings (43)

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 99% confidence

Finding

The declared description promises a domain-specific Xiaohongshu data collection and analysis tool with four concrete capabilities around search, creator works, note details, and comments. However, the supplied code chunk only implements generic CLI utilities: parsing flags, validating numbers, handling boolean options, positional arguments, duplicate detection, warnings, and generating help text. This is supporting infrastructure at best, but in isolation it does not perform any of the declared product behaviors or interact with Xiaohongshu data/resources. Therefore, the code chunk does not accurately represent the declared functionality and should be flagged as a mismatch.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 99% confidence

Finding

The declared description presents a full-featured Xiaohongshu data collection and analysis tool with multiple external data-access capabilities. However, the supplied code chunk does not implement any of those behaviors. It only performs a local supporting utility function: reading package.json from disk and returning the package name with caching. This is materially different from the declared primary purpose, so the description does not accurately represent what this code chunk actually does.

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 83% confidence

Finding

The skill requires access to an environment secret (GUAIKEI_API_TOKEN) but does not declare an explicit tool scope such as allowed tools or permissions. That weakens least-privilege guarantees and makes it harder for a host agent or reviewer to understand what sensitive capabilities the skill needs before execution.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 92% confidence

Finding

The activation rules are broad enough that the skill may trigger for many generic Xiaohongshu-related requests, even when the user did not clearly ask to send data to an external provider. Over-broad routing can cause unintended disclosure of user queries or links to a third-party API and lead to unnecessary secret-backed tool use.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The skill discusses public-data limits but does not prominently disclose that user-supplied Xiaohongshu links, keywords, and possibly related query context are transmitted to guaikei.com. This is a privacy/transparency issue because users may believe analysis happens locally when in fact their inputs are sent to a third party.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 84% confidence

Finding

The README instructs users to invoke the agent by saying Chinese natural-language requests ("然后直接说人话：『帮我找最近一周小红书露营装备的高赞笔记』"), while the overall document is entirely Chinese and does not offer an alternative language or opt-in. Under the policy, forcing a specific language without user choice can be a natural-language policy violation unless clearly justified as region-specific.

Content

No source excerpt is available for this finding.

Whitespace Padding

Medium

• Category: Prompt Injection
• Confidence: 70% confidence

Finding

Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 92% confidence

Finding

This markdown file contains user-facing troubleshooting guidance exclusively in Chinese, including headings, instructions, and support information. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale constraint is explicitly documented and justified.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

This JavaScript file uses Chinese-only natural-language documentation and runtime status messages, indicating the skill is designed around a single language with no opt-in or locale-selection mechanism. Under the policy, forcing a specific language without user choice is a natural-language policy violation unless the locale restriction is explicitly justified.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 94% confidence

Finding

This code hardcodes user-facing comments, error messages, and help text in Chinese, including thrown errors and CLI help output. That creates a locale/language constraint for end users without offering a language selection or documenting an opt-in, which matches the language-policy violation criteria.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The code emits user-facing error messages in Chinese only, and later also prints a success message in Chinese. This is a natural-language locale policy concern because the skill does not offer a language choice or document that it is intentionally limited to a Chinese-speaking context.

Content

No source excerpt is available for this finding.
