Security checks for vulnerabilities and agentic risk

Overview

This skill is a local restaurant sales reconciliation checker that reads a user-provided report and does not show hidden network, persistence, credential, or destructive behavior.

Install only if you are comfortable running a local Node.js script that reads restaurant sales report files you provide. The tool’s output and help text are mainly Chinese, and it is not a full financial audit; it only checks the disclosed table arithmetic and consistency rules.

Finding

The file’s natural-language comments and user-facing guidance are entirely in Chinese, including operational instructions and disclaimers, with no indication that the skill is region-specific or that users may choose another language. This creates a locale/language policy concern because it effectively mandates one language without opt-in.

Confidence

Finding

The user-facing description, usage text, errors, and output are all written exclusively in Chinese, indicating the skill is designed to operate in a single language. There is no visible option for users to choose another language or explicit justification that the skill is limited to a Chinese-speaking or region-specific context.

Finding

The inline comment says non-JSON input is treated as plain text material, giving '例如直接粘贴的合同全文' as an example. That contradicts the skill's stated purpose and surrounding documentation, which consistently require a 门店日营业款上报表 with headers rather than arbitrary contract text.
