Tag your best Shopify customers in Drip

**Objective:** Apply the Drip tag `{tag}` (default vip) to every active Drip subscriber whose Shopify customer record shows total-spent of at least `{min-spent}`.

**Step 1: Find the high-value Shopify customers**

Call `shopify-get-customer` with `total-spent.min` set to `{min-spent}` and `max-records` set to 100. Keep customers with an email.

**Step 2: Match them in Drip**

For each customer, call `drip-get-subscriber` with `email` set to the Shopify email. Keep only subscribers whose status is active. Skip anyone whose Drip tags already include `{tag}` (or vip).

**Step 3: Confirm**

Show the list to tag (email, Shopify name, total-spent, orders-count, current Drip tags) and counts of customers skipped because they are absent from Drip, unsubscribed or already tagged. Ask the user to confirm. Do not continue without a clear yes.

**Step 4: Tag them**

For each confirmed subscriber, call `drip-add-subscriber-tag` with `email` set to the email Drip returned and `tag` set to `{tag}` (or vip).

**Step 5: Verify and report**

Re-read a sample of up to 5 tagged people with `drip-get-subscriber` and confirm the tag is present. Report tagged, failed and skipped counts.

**Rules & Guidelines:**

* `shopify-get-customer` is on the shopify server; `drip-get-subscriber` and `drip-add-subscriber-tag` are on the drip server.
* `drip-add-subscriber-tag` is the only tool that may write, and only after Step 3's confirmation.
* Do NOT call `drip-add-subscriber`, `drip-remove-subscriber-tag`, `drip-add-subscriber-to-campaign` or `shopify-update-customer`. Never create a Drip subscriber here.

**Validation:**

* If no Shopify customers meet `{min-spent}`, say so and stop.
* `{min-spent}` is in the shop's currency; say which currency the report assumes.
* If Shopify returned exactly 100 customers, say the list may be truncated and suggest a higher `{min-spent}`.
