See a customer's GP account and TickTick work together

**Objective:** Trace GP customer `{customer-id}` across both systems: its account position in Dynamics GP and any TickTick tasks, comments and completed work that mention the customer (looking back `{lookback-days}` days for completed work, default 30).

**Step 1: Establish the customer in Dynamics GP**

Call `dynamics-gp-get-rm-customer` (Dynamics GP server) with `customer-id` = `{customer-id}`. If nothing is returned, say the customer does not exist in GP and stop. Keep `customer-name`, `customer-balance`, `credit-limit-amount`, `hold` and `contact-person`.

Call `dynamics-gp-get-rm-trx` (Dynamics GP server) with `customer-id` = `{customer-id}` and keep the 10 most recent documents with their `document-type`, `document-number`, `document-date`, `due-date` and `current-transaction-amount`.

Call `dynamics-gp-get-srv-service-call` (Dynamics GP server) with `customer-id` = `{customer-id}` and keep the open calls (`service-call-number`, `service-call-status`, `priority-level`).

**Step 2: Carry the customer across to TickTick**

TickTick has no customer id field, so the join is text. Call `ticktick-get-tasks` (TickTick server) with `title.contains` = the GP `customer-name` (use the most distinctive word if the full name returns nothing, and say you did so), then again with `title.contains` = `{customer-id}`. Merge the results by task `id`.

For each matching task call `ticktick-get-task-comments` (TickTick server) with its `task-id` and `project-id`. Call `ticktick-get-completed-tasks` (TickTick server) with `title.contains` = the customer name and `completed-time.from` set `{lookback-days}` days back.

**Step 3: Report**

1. GP account position: balance, credit limit, hold flag, last 10 documents, open service calls.
2. Open TickTick tasks: title, project-name, due-date, priority, assignee.
3. Recently completed TickTick tasks and the latest comment on each open task.
4. Gaps: overdue documents or open service calls with no matching TickTick task.

**Rules & Guidelines:**

* Tools whose names start with dynamics-gp run on the Dynamics GP server; tools whose names start with ticktick run on the TickTick server.
* This prompt is read-only. Do not call any tool that adds, updates, completes, moves, deletes or assigns (for example `ticktick-add-task`, `ticktick-update-task`, `ticktick-complete-task`, `ticktick-delete-task`, `ticktick-batch-tasks`, `ticktick-add-comment`) on the TickTick server, and do not call any Dynamics GP tool that creates or updates records or notes.
* A TickTick task counts as a match only if its title visibly names the customer or id; list the match basis for each.

**Validation:**

* If TickTick returns no tasks, report the customer as present in GP and absent from TickTick, and still give Step 1.
* If a customer name matches tasks for a different customer, list them as uncertain instead of attributing them.
