wangrongding/wechat-bot ? reverse-engineered prompt

Build me a simple AI chat bot app I can run locally that connects to WeChat first, and also supports Lark, Telegram, and WhatsApp. I want to sign in to WeChat by scanning a QR code in the terminal, then have the bot read incoming messages and send replies through an AI provider I can switch between, like Pi, ChatGPT, Claude, DeepSeek, or Ollama.

Please make the main flow easy to start with a small setup file and sensible defaults. I want private replies to only work for people on an allow list, and group replies to only work in approved groups when the bot is mentioned. I also want commands to browse local WeChat chats, contacts, group members, and Moments cache, plus run simple stats or AI analysis on a friend or group chat.

Keep the WeChat risk warning in mind and make the default behavior conservative. If possible, include basic send and receive support for the other messaging apps too. Look up current docs online if you need to.
