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},...]. |

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).
