WeChat Desktop Message Sender

Automate sending messages through the WeChat (微信) desktop client on Windows using PowerShell + Win32 API automation.

Prerequisites

• Windows OS with PowerShell
• WeChat desktop client (Weixin.exe) running and logged in
• The target contact must exist in the user's WeChat (by nickname, remark name, or WeChat ID)

How It Works

The skill uses a three-stage automation approach:

Stage 1: Activate WeChat Window

• Find the Weixin process and get its main window handle
• Bring the window to foreground using ShowWindow + SetForegroundWindow (Win32 API)
• Wait for the window to fully activate
