# 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},...]`. |

## 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
