Place a WooCommerce order for a customer, right first time

**Objective:** Create a WooCommerce order for the customer `{customer-email}` containing `{items}` (up to three lines, each a SKU and a quantity), mark it paid only if `{set-paid}` is true (default false), and email the invoice only if `{send-invoice}` is true (default false).

**Step 1: Find the customer**

Call `woocommerce-get-customer` with `email` = `{customer-email}`. Keep `customer-id`, `first-name` and `last-name`.

If there is no match, ask the user whether to (a) create the customer with `woocommerce-add-customer`, giving at least `email` and the name, or (b) place a guest order. Do nothing until they choose.

**Step 2: Resolve every line**

Parse `{items}` into SKU and quantity pairs. More than three lines: stop, since the tool takes three. For each SKU:

1. `woocommerce-get-product` with `sku`. A `simple` product: use its product id.
2. No match: `woocommerce-get-product-variation` with `sku`. A match: use `product-variation-id`, as the order tool expects the variation's id.
3. A `variable` parent: list its variations with `woocommerce-get-product-variation` (`product-id`) and stop so the user can choose.
4. Not found, `outofstock`, or `stock-quantity` below the quantity requested: report it and stop.

**Step 3: Confirm**

Show: customer (or "guest"), each line with name, SKU, quantity, unit `price` and line amount, the estimated subtotal before tax and shipping, status `pending` unless paid, whether it is marked paid, and whether the invoice will be emailed. Say that marking it paid moves it to `processing` and reduces stock. Wait for an explicit yes.

**Step 4: Create**

If the user chose (a) in Step 1, call `woocommerce-add-customer` once and use the returned `id`.

Call `woocommerce-add-order` once with `customer-id` (empty for a guest), `billing-email` = `{customer-email}`, `billing-first-name`, `billing-last-name`, `line1-product-id` and `line1-quantity` (and lines 2 and 3 where given), and `set-paid` = true only when `{set-paid}` is true.

If `{send-invoice}` is true, call `woocommerce-send-order-details` once with the new order's `id`.

**Step 5: Verify and report**

Call `woocommerce-get-order-line` with `order-id` = the new id. Report the order number, status, total and currency, the lines as stored, and whether the invoice was sent.

**Rules & Guidelines:**

* The only write tools this prompt may call are `woocommerce-add-customer` (once, only if the user chose it), `woocommerce-add-order` (once) and `woocommerce-send-order-details` (once, only if asked).
* Do not call any other write tool (`woocommerce-update-order`, `woocommerce-add-order-note`, `woocommerce-add-refund`, `woocommerce-update-customer`, `woocommerce-add-product`, `woocommerce-update-product`, `woocommerce-update-product-variation`, `woocommerce-add-coupon`, `woocommerce-update-coupon`).
* Never retry `woocommerce-add-order` after an error without checking with `woocommerce-get-order` (`customer-email`, today's `created-date.from`) that no order was created, or the customer gets a duplicate.

**Validation:**

* If `{items}` cannot be read as SKU and quantity pairs, ask for it in the form "SKU x quantity, SKU x quantity" and stop.
* Quantities must be whole numbers of 1 or more.
* If `{set-paid}` or `{send-invoice}` is empty, treat it as false.
* If the user's confirmation is anything other than a clear yes, stop without writing.
