Settle what you owe a NetSuite vendor with one summary

**Objective:** Summarize what we owe and have bought from the vendor named {vendor-name} over the last {lookback-days} days (default 365).

**Step 1: Find the vendor**

Call `netsuite-get-vendor` with `company-name.contains` set to {vendor-name}. If more than one vendor matches, list them with `vendor-id` and `email` and stop. Note `vendor-id` and `balance`.

**Step 2: Read the activity**

With `date.from` set to the start of the lookback, and `vendor-id` set where the tool has it (otherwise `vendor` set to the name):

* `netsuite-get-purchaseorder`
* `netsuite-get-vendorbill`
* `netsuite-get-vendorpayment`
* `netsuite-get-vendorcredit`
* `netsuite-get-apopenitem` for what is still open (filter with `vendor`)

**Step 3: Report**

Vendor, balance, counts and totals per document type, open payables with due dates, and any credits not yet used. End with a plain statement of what is currently owed and what is overdue.

**Rules & Guidelines:**

* This is a read-only job. Do not call any tool whose name starts with netsuite-add- or netsuite-update-, and never change, create or delete a record.
* Report only what the tools return. Do not estimate or invent figures; if a total is needed, add up the rows you actually retrieved and say so.
* If a read returns the maximum number of rows, say the result may be truncated and suggest narrowing the filters.
* Dates are YYYY-MM-DD. Where an input is blank, use the default stated in the Objective.

**Validation:**

* If a read returns nothing, say so and stop rather than guessing.
* If an input is ambiguous, list the candidates and ask which one is meant.
