order（order 演示文稿）

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

How to call the underlying commands

Invoke via the OpenClaw gateway node invoke API:

• command: one of order.getGoods, order.getSelectedGoods, order.addGoods, order.removeGoods, order.clearGoods, order.submitOrder, order.batchAddGoods.
• paramsJSON: JSON object string, or null for no-param commands.

order.getGoods

• command: "order.getGoods"
• paramsJSON: null or "{}"
• Success: payload is a JSON array of { "id", "name", "priceCents", "price" }.

order.getSelectedGoods

• command: "order.getSelectedGoods"
• paramsJSON: null or "{}"
• Success: payload is a JSON array of cart items with id, name, quantity, priceCents, subtotalCents.

order.addGoods

• command: "order.addGoods"
• paramsJSON: provide id or name (or both); optional quantity (default 1).

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

or

  { "name": "拿铁", "quantity": "1" }

• Success: payload includes success: true and message (e.g. "已添加 拿铁 x1").

order.removeGoods

• command: "order.removeGoods"
• paramsJSON: same shape as addGoods (id or name, optional quantity).

order.clearGoods

• command: "order.clearGoods"
• paramsJSON: null or "{}".

order.submitOrder

• command: "order.submitOrder"
• paramsJSON: null or "{}".
• Success: payload includes success, message, totalCents, items. Cart is cleared after submit.
• Error: CART_EMPTY if cart is empty.

order.batchAddGoods

• command: "order.batchAddGoods"
• paramsJSON: { "list": "[{\"id\":\"1\",\"quantity\":2},{\"id\":\"2\",\"quantity\":1}]" }
• Success: payload includes success and message (e.g. "已批量添加 2 项").

Error handling

• GOODS_NOT_FOUND: No menu item matched the given id or name. Suggest calling order.getGoods to see the menu.
• NOT_IN_CART: Item not in cart when removing.
• CART_EMPTY: Cannot submit when cart is empty.
• INVALID_REQUEST: Missing or malformed params (e.g. empty list for batchAddGoods).

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).
