Turn Mailchimp campaign clickers into Salesforce leads the same day

**Objective:** Create a Salesforce lead for each person who clicked the Mailchimp campaign titled `{campaign-title}` and has no contact or lead in Salesforce, with lead source `{lead-source}` (default Email Campaign).

**Step 1: Find the campaign and its clickers**

Call `mailchimp-get-campaign` with `title.contains` set to `{campaign-title}`. If more than one campaign matches, list them and stop so the user can choose. Call `mailchimp-get-campaign-email-activity` with that `campaign-id` and `action` set to click, and reduce to unique email addresses. Use `mailchimp-get-campaign-recipient` with the `campaign-id` and `email-address` for each person's first-name, last-name and company.

**Step 2: Remove anyone already in Salesforce**

For each email, call `salesforce-get-contact` with `email`, then `salesforce-get-lead` with `email`. Drop anyone either call returns. Also drop anyone `mailchimp-get-campaign-unsubscribe` returns for that `campaign-id` and `email`.

**Step 3: Confirm**

Show the remaining people as a table: email, first name, last name, company. Salesforce requires a last name and a company; mark any row missing either, and leave those rows out unless the user supplies the values. Ask the user to confirm before creating anything. Do not continue without an explicit yes.

**Step 4: Create**

For each confirmed row, call `salesforce-add-lead` once with `email`, `first-name`, `last-name`, `company` and `lead-source` set to `{lead-source}`. Leave `status` unset so Salesforce applies its default.

**Step 5: Report**

List each lead created with its email, plus any row that failed and the error. Give the totals: clickers, already in Salesforce, unsubscribed, skipped for missing fields, created.

**Rules & Guidelines:**

* `mailchimp-get-campaign`, `mailchimp-get-campaign-email-activity`, `mailchimp-get-campaign-recipient` and `mailchimp-get-campaign-unsubscribe` are on the mailchimp server. `salesforce-get-contact`, `salesforce-get-lead` and `salesforce-add-lead` are on the salesforce server.
* The only write this prompt may make is `salesforce-add-lead`, once per confirmed person, after the user confirms. Do not call `salesforce-add-contact`, `salesforce-update-lead` or any mailchimp add or update tool.

**Validation:**

* Compare email addresses case-insensitively before deciding someone is new; a duplicate lead is worse than a missed one.
* If no clickers remain after Step 2, say so and stop without asking for confirmation.
* If a create fails, report it and carry on with the rest; do not retry it automatically.
