Move Dynamics 365 Sales deals forward with every change explained

**Objective:** Apply `{change}` to the opportunity `{opportunity-topic}` (id `{opportunity-id}`), after the user has seen the before and after, and record the reason as a note.

**Step 1: Read the current state**

Call `dynamics-365-sales-get-opportunities` with `topic` = `{opportunity-topic}`. If it matches none or more than one, stop and ask. Note the current `sales-stage`, `probability`, `est-revenue`, `est-close-date`, `rating` and `status`. If the opportunity is not open, stop: closed opportunities are not updated here.

**Step 2: Sense-check the change**

Turn `{change}` into field values for `sales-stage`, `probability`, `estimated-revenue`, `estimated-close-date`, `rating` or `description`. Then check:

* a close date must not be in the past
* probability must be a whole number from 0 to 100, and should rise as the stage advances; flag a later stage with a lower probability
* a revenue change of more than 25% should be checked against `dynamics-365-sales-get-opportunityproducts` (with `opportunity` = the topic); say whether the products support it

**Step 3: Confirm**

Show a before and after table of only the fields that change, plus any warnings from Step 2, and the note text that will record the reason. Ask for one confirmation.

**Step 4: Write**

1. `dynamics-365-sales-update-opportunity` with `id` = `{opportunity-id}` and only the changed fields.
2. `dynamics-365-sales-create-note` with `regarding-id` = `{opportunity-id}`, `title` = "Opportunity updated", and `text` = what changed and why.

**Step 5: Verify**

Call `dynamics-365-sales-get-opportunities` with `topic` again and confirm the new values are stored. Report any field that did not change as expected.

**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-opportunity` and `dynamics-365-sales-create-note`, each once, after the confirmation.
* Pass only the fields being changed. Never blank a field the user did not mention.

**Validation:**

* If `{opportunity-id}` is not a GUID, stop and explain where to find it.
* If `{change}` does not map clearly to fields, ask what is meant before changing anything.
