Find store SKUs missing from Dynamics GP and drifting prices

**Objective:** Compare the WooCommerce catalog with Dynamics GP items, matching store SKU to GP item number, for products in category {category} (default: all categories), up to {max-products} products (default 100), and report SKUs missing from GP and list price differences in currency {currency-id} (default: whatever currency GP returns).

**Step 1: Read the store catalog (woocommerce)**

Call `woocommerce-get-product` with max-records set to {max-products} (default 100), and categories.contains set to {category} when it is given. For every product whose type is variable, call `woocommerce-get-product-variation` with its product-id, because the variations carry the SKUs and prices. Keep the sku, name, regular-price and product or variation id of each. Set aside any product or variation that has no SKU.

**Step 2: Find each SKU in Dynamics GP (dynamics-gp)**

For each SKU call `dynamics-gp-get-iv-item` with item-number set to the SKU. If nothing comes back, record the SKU as in the store but not in GP and continue with the next one.

**Step 3: Compare list prices (dynamics-gp)**

For each matched item call `dynamics-gp-get-iv-item-price` with item-number, and currency-id set to {currency-id} when it is given. Use the row whose unit-of-measure equals the item's selling-u-of-m from step 2. Compare its list-price with the store regular-price. A difference under 0.01 is a match.

**Step 4: Report**

1. In the store, not in GP: SKU and product name.
2. Price differences: SKU, product name, store regular price, GP list price, difference. Sort by the largest difference.
3. No SKU in the store: product name and id.
4. Summary: products checked, matched, missing from GP, price differences, no price in GP.

**Rules & Guidelines:**

* Tools whose names start with woocommerce- are on the woocommerce MCP server; tools whose names start with dynamics-gp- are on the dynamics-gp MCP server. If a tool from either server is not available, stop and say which server is not connected.
* If the user names a Dynamics GP company, pass it as company on every dynamics-gp call.
* Match a store SKU to a GP item number exactly, after trimming spaces. If that fails, try the SKU in upper case once. Never match on descriptions or partial codes.
* This prompt is read-only. Do not call `woocommerce-update-product`, `woocommerce-update-product-variation`, `woocommerce-add-product`, `dynamics-gp-iv-item-add`, `dynamics-gp-iv-item-update`, `dynamics-gp-iv-item-price-add` or `dynamics-gp-iv-item-price-update`. To fix prices, point the user to the sync-prices-from-gp prompt.
* Work from the store side only. Do not page through every GP item looking for items the store lacks.

**Validation:**

* If step 1 returns no products, say so and stop.
* If GP returns several price rows for the selling unit of measure (for example one per currency) and {currency-id} was not given, list them all and do not flag a difference.
* If GP has no price row for the selling unit of measure, report the price as missing in GP, not as a difference.
