Put your biggest Shopify spenders in a Mailchimp segment

**Objective:** Find Shopify customers who have spent at least `{min-total-spent}` and add the ones already subscribed to the Mailchimp audience `{list-name}` into its static segment `{segment-name}`, after confirmation.

**Step 1: Resolve the audience and segment in Mailchimp**

Call `mailchimp-get-list` with `name` = `{list-name}`; it must match exactly one audience, otherwise list the matches and stop. Note `list-id`. Then call `mailchimp-get-segment` with `list-id` and `name` = `{segment-name}`. It must match exactly one segment, and its `type` must be static; a saved (condition-based) segment cannot have members added, so stop and say so.

**Step 2: Top spenders from Shopify**

Call `shopify-get-customer` with `total-spent.min` = `{min-total-spent}` and `max-records` = 250. Keep `email`, `name`, `total-spent` and `orders-count`, and skip customers without an email.

**Step 3: Filter against Mailchimp**

For each customer:

* Call `mailchimp-get-list-member` with `email` and `list-name` = `{list-name}`. Keep them only if `status` is subscribed. Count the others as "not subscribed" and do not add them; a segment cannot hold non-members.
* Call `mailchimp-get-segment-member` with `segment-id`, `list-id` and `email`. If they are already in the segment, count them as "already in segment".

**Step 4: Confirm**

Show the people to add (name, email, total spent, orders) and the counts for each skip reason. Ask the user to confirm. Do not continue without an explicit yes.

**Step 5: Add and verify**

For each confirmed person call `mailchimp-add-segment-member` once with `segment-id`, `list-id` and `email-address`. Then call `mailchimp-get-segment` again with `segment-id` and report the new `member-count` beside the old one, plus added, failed (with error) and skipped counts.

**Rules & Guidelines:**

* `shopify-*` tools are on the shopify server and are read only here; `mailchimp-*` tools are on the mailchimp server.
* The only write tool this prompt may call is `mailchimp-add-segment-member`, only in Step 5, only after confirmation. Do NOT call `mailchimp-add-list-member`, `mailchimp-update-list-member`, `mailchimp-start-automation` or any Shopify add or update tool.
* Match on email only, case-insensitive and trimmed.

**Validation:**

* If `{min-total-spent}` is empty or not a number, ask for one and stop.
* If Step 2 returns 250 customers, say the result was capped and suggest raising `{min-total-spent}`.
