Security checks for vulnerabilities and agentic risk

Overview

This skill only defines a WeChat messaging workflow with user confirmation before sending, and no hidden code, persistence, or unrelated access was found.

Before installing, confirm that the private-network endpoint and WECHAT_APPID belong to your intended WeChat bridge, because the skill can send messages through that service once you approve the recipient and content.
