Answer where-is-my-order emails in one step

**Objective:** Find out where the order `{order-number}` (or the most recent order for the customer `{customer-email}`) is right now, and draft a short, accurate reply to the customer.

**Step 1: Find the order**

If `{order-number}` is given, call `shopify-get-order` filtered by `order-number`. If that returns nothing, retry with `name` set to the number prefixed with #. If only `{customer-email}` is given, call `shopify-get-order` filtered by `email` and take the most recent order by created-at. If both are empty, ask for one and stop. If several orders match and none is clearly the one meant, list them (order number, date, total, fulfillment status) and stop.

Note the order-id, financial-status, fulfillment-status, cancelled-at and created-at.

**Step 2: Check what has shipped**

* Call `shopify-get-fulfillment` filtered by `order-id` for each shipment's status, shipment-status, tracking company and tracking number.
* Call `shopify-get-fulfillment-event` filtered by `order-id` and take the latest event per fulfillment (happened-at, status, city, estimated-delivery-at).
* If there are no fulfillments, or tracking is missing, call `shopify-get-fulfillment-tracking-info` filtered by `order-id` as a fallback.

**Step 3: Check what has not shipped**

* Call `shopify-get-order-line` filtered by `order-id`. Any line with fulfillable-quantity above zero is still to ship.
* For unshipped items, call `shopify-get-fulfillment-order` filtered by `order-id` to see status, assigned location and fulfill-by date, and `shopify-get-fulfillment-order-hold` filtered by `order-id` to see whether anything is on hold and why (display-reason).

**Step 4: Report**

First a staff summary:

* Order: number, date, payment status, overall fulfillment status
* Shipped: per shipment, the items, carrier, tracking number, latest scan and estimated delivery
* Not yet shipped: items, location, fulfill-by date, and any hold reason

Then a customer reply of 3 to 6 sentences in plain language: what has shipped, where it is, when it should arrive, and what is still to come. Do not mention internal hold reasons, app names or risk checks in the customer reply; say only that the item is being prepared or is delayed.

**Rules & Guidelines:**

* This prompt is read-only. Do not call `shopify-update-order`, `shopify-update-customer` or any other add or update tool.
* Never promise a delivery date the carrier data does not show. If there is no estimated-delivery-at, say the carrier has not given one.
* If the order is cancelled (cancelled-at is set), say so first and do not describe it as in transit.

**Validation:**

* If no order matches, say so and ask the user to confirm the order number or email. Do not guess at a similar order.
* If the latest tracking event is more than 7 days old and not delivered, flag the shipment as possibly stalled in the staff summary.
