Follow up in Pipedrive with everyone who clicked your campaign

**Objective:** Schedule a Pipedrive follow-up activity for every person who clicked the Constant Contact campaign `{campaign-name}`, due `{due-date}` (default: the next business day), of activity type `{activity-type}` (default call). Write nothing until the user confirms the plan.

**Step 1: Find the clickers (Constant Contact)**

Call `constant-contact-get-campaign` with `name` set to `{campaign-name}` (fall back to `name.contains`; if more than one matches, list them and stop). Then call `constant-contact-get-campaign-click` with the `campaign-id` and group by `email-address`, keeping click counts and the links clicked.

**Step 2: Match them in Pipedrive**

For each email, call `pipedrive-get-person` with `email`. Skip anyone not found and list them in the report; this prompt does not create people.

**Step 3: Check the activity type and existing follow-ups (Pipedrive)**

* Call `pipedrive-get-activity-type` and confirm `{activity-type}` (default call) is an active key. If it is not, list the valid keys and stop.
* For each matched person, call `pipedrive-get-activity` with `person-id`, `done` set to false and `due-date.from` set to today. If they already have an open activity, skip them and show it.
* If the person has an `organization-id`, call `pipedrive-get-deal` with it and `status` set to open. If exactly one open deal is found, link it; otherwise link none.

**Step 4: Confirm the plan**

Show a table: person, email, clicks, deal to link (or none), subject, due date. Use the subject "Follow up: {campaign-name}" and a note listing the links they clicked. Ask the user to confirm. Do not continue without an explicit yes.

**Step 5: Create the activities (Pipedrive)**

For each confirmed row, call `pipedrive-add-activity` once with `person-id`, `deal-id` if any, `org-id`, `type`, `subject`, `due-date` and `note`.

**Step 6: Confirm**

Call `pipedrive-get-activity` with each `person-id` and `done` set to false, and report which activities now exist and which calls failed.

**Rules & Guidelines:**

* `constant-contact-get-campaign` and `constant-contact-get-campaign-click` are on the constant-contact server. Every other tool here is on the pipedrive server.
* The only tool allowed to write is `pipedrive-add-activity`, and only after Step 4 is confirmed. Do NOT call `pipedrive-add-person`, `pipedrive-add-lead`, `pipedrive-add-deal`, `pipedrive-update-deal`, or any Constant Contact add or update tool.

**Validation:**

* If `{due-date}` is given, it must be an ISO date (YYYY-MM-DD) that is today or later. Otherwise ask for a valid date before Step 4.
* If no clicker matches a Pipedrive person, report that and stop without writing.
* Never create two activities for the same person in one run.
