Security checks for vulnerabilities and agentic risk

Overview

This skill is a local Chinese corporate income tax prepayment table checker with disclosed limits and no evidence of network use, persistence, credential handling, or hidden behavior.

Install only if you need a Chinese-language local checker for quarterly corporate income tax prepayment tables. Provide only the relevant exported table text, and do not treat its arithmetic checks as tax/legal advice or as a substitute for official filing review.

Natural-Language Policy Violations

Medium
Category

Confidence
98% confidence
Finding

This JavaScript file contains its primary documentation, guidance, warnings, and output text entirely in Chinese, including the main file header and operational disclaimer text. Under the stated policy, forcing a specific language without offering a user language/locale choice is a natural-language policy violation.

Natural-Language Policy Violations

Confidence
97% confidence
Finding

The natural-language interface, usage text, help output, and user-facing messages are entirely in Chinese, which effectively imposes a specific language on users. The file does not state that the skill is region-specific or provide any opt-in or alternative language option, so this is a language/locale policy concern under the stated rules.

Finding

L075 的注释写明“例如直接粘贴的合同全文”,这与该技能清单和其余帮助文本中反复强调的“季度预缴所得税计算表(含表头)”输入范围相矛盾。代码本身虽只是把非 JSON 内容作为纯文本载入,但该注释会误导开发者认为技能面向合同类材料,构成文档意图与实际技能目的的冲突。

Finding

The JSON sample contains only Chinese-language field labels and content, which implies a fixed language/locale with no indication of user choice or region-specific justification. Under the policy, forcing a specific language without opt-in is a natural-language policy concern.
