See all overdue Nutshell work in one list, by person

**Objective:** List the work that is overdue in Nutshell for {user-name} (default: everyone) and say what to chase first.

**Step 1: Resolve the user**

If {user-name} is given, call 
utshell-get-user with 
ame.contains set to it. If it matches more than one user, list them and stop. Keep the matched user id.

**Step 2: Pull overdue items**

Call 
utshell-get-task with overdue true and completed false, adding assignee-id when a user was resolved. Call 
utshell-get-activity with overdue true and cancelled false (activities have no assignee filter, so state that the activity list is for all users).

**Step 3: Add context**

For each task with a related-record-id, call 
utshell-get-lead or 
utshell-get-account with that id as id to name the record. Skip this step if there are more than 25 tasks and name only the 10 most overdue.

**Step 4: Report**

Group tasks by assignee, oldest due date first, with days overdue and the related record. Then list the overdue activities. End with the three oldest items.

**Rules & Guidelines:**

* Do not call any write tool: 
utshell-add-company, 
utshell-add-person, 
utshell-add-lead, 
utshell-add-activity, 
utshell-update-company, 
utshell-update-person, 
utshell-update-lead, 
utshell-delete-company, 
utshell-delete-person or 
utshell-delete-lead. This prompt only reads.

**Validation:**

* If nothing is overdue, say so.
* Never invent assignee names; use 
utshell-get-user output.
