Android Order Skill (点餐)

This skill uses the paired Android device (OpenClaw SMS Demo app with order capability) to manage an in-app menu and cart: get menu, add/remove items, view cart, submit order. Inspired by EdgeOSToolService (MEOW PAY); implementation is in-memory on the device (demo, no real POS backend).

When to use this skill

• User asks to order food/drinks, view menu, add to cart, or submit an order on the paired Android device: use the order.* commands below.

Commands overview

Command	Description
order.getGoods	Return menu (id, name, priceCents, price).
order.getSelectedGoods	Return current cart with quantities and subtotals.
order.addGoods	Add by id or name (and optional quantity).
order.removeGoods	Remove by id or name (and optional quantity).
order.clearGoods	Clear cart.
order.submitOrder	Submit cart as order; returns summary (demo only).
order.batchAddGoods	Add multiple items: list = [{"id":"1","quantity":2},...].

  { "id": "1", "quantity": "2" }
  

  or

Demo menu (default on device)

The in-app menu includes items such as: 拿铁, 美式, 卡布奇诺, 三明治, 沙拉, 蛋糕 (with ids "1"–"6"). Use order.getGoods to get the current list and prices.

Safety notes

• This is a demo flow: submit order does not charge or send to a real POS. Do not expose as real payment.
• Prefer confirming with the user before submitting an order (e.g. read back cart and total).
