See what a customer owes and the work in flight for them

**Objective:** Give an account brief for Business Central customer `{customer-number}`: money and commercial status from Business Central, and the related work in Asana. Read only.

**Step 1: Read the customer in Business Central**

Call `business-central-get-customer` with `customer-number` set to `{customer-number}` and `company` set to `{company}` if given. If nothing comes back, say so and stop. Keep `name`, `balance`, `balance-due`, `credit-limit`, `salesperson-code`, `payment-terms-code` and `blocked`.

**Step 2: Read the customer's open items**

* `business-central-get-posted-sales-invoice` with `sell-to-customer-number` set to `{customer-number}` and `remaining-amount.min` set to 0.01. Mark each invoice overdue if its `due-date` is before today, with days overdue.
* `business-central-get-job` with `bill-to-customer-number` set to `{customer-number}`. Keep open jobs.
* `business-central-get-customer-comment` with `customer-number` set to `{customer-number}`. Keep the five most recent.

**Step 3: Find related work in Asana**

Call `asana-get-tasks` with `name.contains` set to the customer name and `completed` false. Then, for each open job from Step 2, call `asana-get-project` with `name.contains` set to the job number. If the customer name is shorter than 4 characters or is a common word, say the task search may be noisy and show only tasks whose name also contains the customer number or an invoice or job number.

**Step 4: Report**

* Header: customer name and number, salesperson, payment terms, blocked status.
* Money: balance, balance due, credit limit and headroom, and the overdue invoices (number, due date, days overdue, remaining amount).
* Work: open jobs with their Asana project and status if found, and open Asana tasks that mention the customer, with assignee and due date.
* Notes: the recent comments.
* Attention: overdue invoices with no Asana task mentioning their invoice number, and open jobs with no Asana project.

**Rules & Guidelines:**

* `business-central-get-customer`, `business-central-get-posted-sales-invoice`, `business-central-get-job` and `business-central-get-customer-comment` are on the business-central server; `asana-get-tasks` and `asana-get-project` are on the asana server.
* Read only. Do not call `asana-create-task`, `asana-create-comment` or any other asana create or update tool, and do not call `business-central-update-customer` or any other business-central create or update tool.

**Validation:**

* If Asana returns nothing, report the Business Central half and say no Asana work mentions this customer.
* Show amounts in the customer's currency as Business Central returns them; do not convert.
