Security checks for vulnerabilities and agentic risk

Overview

This skill is a local Chinese text detector and rewriter with no evidence of hidden access, persistence, or data exfiltration.

Install only if you want a Chinese-language local writing helper; expect heuristic AI-trace scoring and style rewriting, but do not rely on the advertised 29-detection claim or pip-install claim without additional packaging support.

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

Finding

The description emphasizes a '真人化引擎' that rewrites Chinese AI text into more human-like style and supports 8 platform-specific rewriting modes. However, the supplied code only analyzes input text and computes an AI-likelihood score with a report. It does not modify text, rewrite style, or provide any platform-specific transformation features. Additionally, while the description mentions 29 AI-trace detections, this code chunk defines only 15 actual detection metrics (p1–p15), despite comments claiming 29. This is a material description-versus-behavior mismatch, with the code's primary purpose being detection rather than humanization.

MCP Tool Poisoning
Confidence

Finding

The description partially matches the rewriting portion: the script clearly supports 8 Chinese platform-oriented rewrites and attempts to make text feel more human via template removal, slang/emoji insertion, hooks, CTA, tags, and some structural variation. However, a major part of the declared purpose is unsupported: there is no code for '29 AI-trace detection' or any detector, classifier, scoring, reporting, or analysis features. The packaging claim ('pip install后直接使用') is also not evidenced by this code chunk, which is just a module/script. Because the declaration prominently advertises a detection engine in addition to rewriting, while the actual code only implements rewriting utilities, this is a material description-behavior mismatch.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The manifest and heading describe the skill exclusively as a Chinese text humanization engine and present usage entirely in Chinese, with no indication that users can choose another language or locale. This creates a natural-language locale constraint without documented opt-in or justification as a region-specific compliance tool.

Natural-Language Policy Violations

Not specified by scanner
Confidence
95% confidence
Finding

This code file contains user-facing natural-language strings that present the tool entirely in Chinese, including the product description and command help. Under the policy, forcing a specific language without user opt-in or a clearly documented justified locale constraint is a natural-language policy violation.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The module description and usage examples state that the detector is specifically for Chinese text and all user-facing output strings are in Chinese. This imposes a language/locale constraint without any opt-in or alternative, which matches the policy category for forced language behavior.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The module description and example usage present the skill as exclusively producing Chinese-platform style text, and the public API later restricts platform choices to Chinese platforms only. This is a natural-language locale constraint with no opt-in or alternative language path documented, which fits the policy category for forced language/locale behavior.
