Brief yourself on a Business Central customer before a call

**Objective:** Produce a briefing for customer `{customer-number}` in company `{company}`, combining their Business Central account position with the open and recent TickTick work that mentions them.

**Step 1: Identify the customer (Business Central)**

Call `business-central-get-customer` with `company` set to `{company}` and `customer-number` set to `{customer-number}`. If nothing matches, report that and stop. Keep name, balance, balance-due, city and salesperson-code.

**Step 2: Account position (Business Central)**

Call `business-central-get-posted-sales-invoice` with `sell-to-customer-number` set to the customer number and `remaining-amount.min` set to 0.01 for open invoices. Call `business-central-get-customer-comment` with `customer-number` to read internal notes. Call `business-central-get-opportunity` with `contact-company-name` set to the customer name for open opportunities.

**Step 3: Related work (TickTick)**

Call `ticktick-get-tasks` with `title.contains` set to the customer name and `status` set to open, then again with `title.contains` set to the customer number. De-duplicate by task id. Call `ticktick-get-completed-tasks` with `title.contains` set to the customer name and `completed-time.from` set to `{lookback-days}` days ago (default 30).

**Step 4: Report**

Sections: Account (balance, balance due, open invoices with due dates), Notes (latest comments), Pipeline (open opportunities), Open tasks (title, due date, priority), Recently completed tasks. End with up to three suggested next actions.

**Rules & Guidelines:**

* `business-central-get-customer`, `business-central-get-posted-sales-invoice`, `business-central-get-customer-comment` and `business-central-get-opportunity` are on the business-central server. `ticktick-get-tasks` and `ticktick-get-completed-tasks` are on the TickTick server.
* This prompt is read-only. Never call `ticktick-add-task`, `ticktick-update-task` or any Business Central create or update tool.

**Validation:**

* Task matching is by name or number text, so say that matches may be incomplete.
* If a section has no data, write "none found" rather than omitting it.
