Escalate cases with a recorded reason and a same-day follow-up

**Objective:** Escalate case `{case-number}` (id `{case-id}`) because `{reason}`: raise its priority, record why, and put a follow-up on the owner's list.

**Step 1: Read the case**

Call `dynamics-365-sales-get-incidents` with `case-number` = `{case-number}`. If nothing matches, stop. Note the title, customer, owner, priority, status, created on and resolve by. If the case is resolved or cancelled, stop: this prompt does not reopen cases.

**Step 2: Context**

* Call `dynamics-365-sales-get-activitypointers` with `regarding` = the case title for the latest activity on it.
* Call `dynamics-365-sales-get-entitlements` with `customer` = the case's customer to note the entitlement and SLA.
* Call `dynamics-365-sales-get-incidents` with `customer` = the customer and open status to see how many other cases they have open.

**Step 3: Confirm**

Show: the current and new priority (the highest value in the tool's schema, unless the case already has it), the note text (the reason, the case age, days since last activity, other open cases for the customer), and the follow-up task (subject "Escalated: " plus the case title, due today). Ask for one confirmation.

**Step 4: Write**

1. If the priority changes: `dynamics-365-sales-update-case` with `id` = `{case-id}` and `priority`.
2. `dynamics-365-sales-create-note` with `regarding-id` = `{case-id}`, `title` = "Escalated", and the note text.
3. `dynamics-365-sales-create-task` with `regarding-id` = `{case-id}`, the subject, `due-date` = today, and `priority` = high.

**Step 5: Verify and report**

Call `dynamics-365-sales-get-incidents` with `case-number` again and confirm the priority. Report what was changed and created, with ids.

**Rules & Guidelines:**

* No read tool returns a record's GUID. A GUID for an existing record must come from the user: it is the `id=` value in the browser address bar when the record is open in Dynamics 365. Never invent, reuse or guess one.
* 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.
* The only write tools this prompt may call are `dynamics-365-sales-update-case`, `dynamics-365-sales-create-note` and `dynamics-365-sales-create-task`, each at most once, after the confirmation.
* The task goes on the case; it cannot be assigned to another user with these tools. Say so if the user asks.

**Validation:**

* If `{case-id}` is not a GUID, stop and explain where to find it.
* If `{reason}` is blank, ask for it: an escalation must record why.
