Security checks for vulnerabilities and agentic risk

Overview

This skill is a local Chinese-language tax self-check table validator that reads user-provided input and does not show evidence of network access, persistence, credential use, or hidden side effects.

Install only if you want a Chinese-language, local Node-based checker for this specific tax self-check table format. Treat its output as table arithmetic/reconciliation help, not tax or legal advice, and only point it at files you intend the local tool to read.

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
Vulnerability Patterns

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The user-facing comments and operational description are entirely in Chinese, including warnings, scope, and usage expectations, with no indication that other languages are supported or that Chinese is optional. This creates a natural-language locale constraint that is not presented as opt-in or justified as a region-specific language requirement.

Natural-Language Policy Violations

Confidence
95% confidence
Finding

The user-facing description, usage text, prompts, and outputs are entirely in Chinese, indicating the skill is effectively constrained to a specific language. The file does not provide any opt-in, fallback, or documented justification for this locale restriction, which matches the language/locale policy violation category.

Intent-Code Divergence

Finding

The inline comment at L075 gives the example 'directly pasted full contract text' (合同全文), which contradicts the rest of the file's stated intent: the tool expects a 税收优惠适用条件自查表 with headers and reports insufficient input when such structure is missing. This is not just incomplete documentation; it actively suggests a different document type than the code and user guidance support.

Natural-Language Policy Violations

Confidence
95% confidence
Finding

The JSON text content is entirely in Chinese and does not indicate that the user can choose another language or locale. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale constraint is clearly documented and justified.
