Brief yourself on a customer from BigCommerce and Nutshell

**Objective:** Build one brief on the customer `{customer-email}` from BigCommerce and Nutshell, looking back `{lookback-days}` days for orders (default 365).

**Step 1: Find the customer in BigCommerce**

Call `bigcommerce-get-customer` with `email` set to `{customer-email}`. If nothing matches, report that the customer is not in BigCommerce and stop. If more than one matches, list them and stop.

**Step 2: Pull their orders**

Take `id` from that result and call `bigcommerce-get-order` with `customer-id` set to it and `date-created.from` set to today minus `{lookback-days}` days. Total `total-including-tax`, count the orders, and note `status`, `refunded-amount` and the latest `date-created`.

**Step 3: Find the CRM contact**

Call `nutshell-get-contact` with `name` set to the BigCommerce customer `name`. If nothing matches, retry with `name.contains` set to the last name. Pick the contact whose `emails` include `{customer-email}`. If none does, report the customer as present in BigCommerce and absent from Nutshell, and skip to Step 5.

**Step 4: Pull the CRM context**

Call `nutshell-get-account` with `id` set to the contact `company-id` (skip if empty). Call `nutshell-get-lead` with `person-id` set to the contact `id` and report `name`, `status`, `value` and `anticipated-close-time` for each lead. Call `nutshell-get-activity` with `name.contains` set to the customer name only if you need recent touchpoints.

**Step 5: Report**

Give: the customer (name, email, company), order count and revenue for the period, refunds, the CRM contact owner and last-contacted date, the account, and open leads. End with one line saying whether the CRM view and the store view agree.

**Rules & Guidelines:**

* `bigcommerce-*` tools are on the bigcommerce server and `nutshell-*` tools are on the nutshell server. Both servers must be connected.
* This is read-only. Never call any add, update or delete tool on either server (for example `bigcommerce-customer-update`, `nutshell-add-person`, `nutshell-update-lead`, `nutshell-delete-company`).

**Validation:**

* If either system returns nothing, say which one and continue with the other.
* If the emails or names differ in case or spacing, treat them as equal and note the difference.
