Start from real tickets, not a demo script
We ask for a sample from the current helpdesk or mailbox and group the intents customers already send. Status questions, simple complaints, policy lookups and billing repeats are usually the first candidates. Strategic accounts, legal threats and anything that needs a commercial exception stay with people.
The first production shape is assistant mode. The agent drafts a reply and a category. An agent on the team accepts or edits. Only after the log shows a stable category do we allow an automatic send for that category alone.
