Yuanbao

Lets you interact with Yuanbao group chats by querying group info, listing members, and most importantly, @mentioning users directly in your replies. The messaging model is clean: your text response gets sent automatically, and @nickname syntax in your message creates real mentions that notify people. You can also send private messages with optional media attachments. Useful if you're building bots or automations for Yuanbao (the Chinese AI chat platform where groups are called "派"). The documentation is unusually explicit about not apologizing for lacking permissions, which suggests this was built after too many false disclaimers from earlier attempts.
