Call the best new leads first, not existing customers

**Objective:** Triage the open leads created in the last `{lookback-days}` days (default 14), optionally only those owned by `{owner}` and from source `{lead-source}`, and produce a ranked call list.

**Step 1: Pull the leads**

Call `dynamics-365-sales-get-leads` with `status` set to the open value, `created-on.from` = today minus the lookback, and `owner` and `lead-source` if given. Set `max-records` to 200.

**Step 2: Check for existing customers and duplicates**

For each lead (up to 50, most recent first):

* If it has a `company-name`, call `dynamics-365-sales-get-accounts` with `account-name` = the company name. A match means the lead is an existing customer and belongs with the account owner.
* If it has an `email`, call `dynamics-365-sales-get-contacts` with `email` = the lead's email. A match means the person is already a contact.
* Two or more leads with the same email, or the same name at the same company, are duplicates.

**Step 3: Rank**

Score each remaining lead: rating (hot before warm before cold), then `est-value` (higher first), then recency (newer first). A lead missing both email and business phone cannot be worked; put it last.

**Step 4: Report**

1. Counts: total, existing customers, existing contacts, duplicates, workable.
2. The ranked call list: name, company, topic, rating, est. value, source, owner, created on, email/phone.
3. Existing-customer and duplicate leads, each with the matching account or contact.
4. Leads that cannot be worked, and what is missing.

**Rules & Guidelines:**

* This prompt is read-only. Do NOT call any create or update tool: `dynamics-365-sales-create-account`, `dynamics-365-sales-create-contact`, `dynamics-365-sales-create-lead`, `dynamics-365-sales-create-opportunity`, `dynamics-365-sales-create-case`, `dynamics-365-sales-create-task`, `dynamics-365-sales-create-note`, `dynamics-365-sales-create-phone-call`, `dynamics-365-sales-update-account`, `dynamics-365-sales-update-contact`, `dynamics-365-sales-update-lead`, `dynamics-365-sales-update-opportunity`, `dynamics-365-sales-update-case`.
* Status, stage, priority, rating and type filters take the values listed in each tool's input schema. Pick from that list; never guess a label.
* Do not treat a lead as a duplicate on name alone; require the same email or the same company too.

**Validation:**

* If no leads match, say so and state the filters used.
* If `{lookback-days}` is blank or invalid, use 14.
