Review a Nutshell deal with its Chorus call scores

**Objective:** For the Nutshell lead `{lead-name}`, show the deal's status and how its recorded Chorus calls scored, looking back `{lookback-days}` days (default 180).

**Step 1: Find the lead in Nutshell**

Call `nutshell-get-lead` (Nutshell server) with `name.contains` set to `{lead-name}`. If more than one lead matches, list them with id, status and value and stop. If none match, say so and stop. Note `status`, `value`, `confidence`, `owner` and the first name in `companies`.

**Step 2: Find its calls in Chorus**

Call `chorus-get-engagements` (Chorus server) with `account-name.contains` set to that company name and `date.from` set to the start of the lookback window. Collect each `conversation-id`.

**Step 3: Pull the scores**

For each `conversation-id` (cap at 10) call `chorus-get-scorecard-scores` (Chorus server) with `conversation` set to it.

**Step 4: Report**

The deal line (status, value, confidence, owner), then a table of calls with date, subject and the scorecard questions and scores returned, then the average score. End with one sentence on whether low-scoring calls line up with a low `confidence` or a stalled status.

**Rules & Guidelines:**

* `nutshell-get-lead` is on the Nutshell server; `chorus-get-engagements` and `chorus-get-scorecard-scores` are on the Chorus server.
* Read only. Do not call any add, update, delete, create, export or playlist tool on either server.

**Validation:**

* If a call has no scorecard, list it as unscored rather than as zero.
* If the lead has no company, or Chorus has no calls for it, report that and show the deal line only.
