How a ticket moves through the pipeline
A customer message arrives, three Claude agents handle it in sequence, and a resolved reply goes back out. Watch where the tokens — and therefore the cost — accumulate.

💡 Notice the middle box. Agent 2 costs the most not because it is slower, but because it carries the most context — the ticket, the category, the customer history and similar past cases all arrive as input tokens. Context length, not agent count, is what drives this bill.
