Find duplicate Nutshell companies and people before they spread

**Objective:** Find likely duplicate {record-type} records (company or contact) in Nutshell and recommend which to keep, without changing anything.

**Step 1: Pull the records**

If {record-type} is company, call 
utshell-get-account with max-records 500. If it is contact, call 
utshell-get-contact with max-records 500. If it is anything else, ask which and stop. If you hit the limit, say the audit covers only the first 500.

**Step 2: Group likely duplicates**

Group records whose names are equal after ignoring case, punctuation and suffixes such as Inc, LLC or Ltd, or that differ by one or two characters. For contacts also group by the same name at the same company-id.

**Step 3: Rank within each group**

For each group call 
utshell-get-lead (company-id or person-id) and 
utshell-get-note (parent-id) for every member to count what hangs off it. Recommend keeping the member with the most linked leads and notes and the latest last-contacted date.

**Step 4: Report**

Each group: members with id, owner, linked leads, notes, last contacted, and the recommended keeper. Order groups by number of linked records.

**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.
* Only propose. Deleting is done separately with the delete-record-safely prompt after the user decides.

**Validation:**

* If no duplicates are found, say so.
