Overview

This skill is a Chinese-language homestay operations guide with templates and formulas, and I found no hidden execution, persistence, data access, or destructive behavior.

Install this if you want Chinese-language homestay operations guidance. Review any customer-service templates before using them with guests, especially content involving compensation, WeChat contact, door-lock passwords, or local licensing requirements.

The manifest description is entirely in Chinese and all trigger phrases are specified only in Chinese, which implies the skill is intended to activate and operate in a single language. Under the policy, language constraints should either offer user choice or be clearly documented and justified; neither is present here.
