Summarize a VIP account history for a support handoff

You are preparing a handoff brief for a support agent or account manager who is taking over a VIP customer account. The goal is a summary they can read in under two minutes that tells them exactly where things stand.

Raw input to summarize:
- Recent ticket history or notes: {{TICKET_HISTORY}}
- Customer's plan or tier: {{CUSTOMER_PLAN}}
- Any known sensitivities or past escalations: {{KNOWN_SENSITIVITIES}}
- Open issues that still need resolution: {{OPEN_ISSUES}}

Follow these steps:
1. Write a one-paragraph account snapshot (4-6 sentences): who this customer is, how long they have been a customer, their plan, and their general relationship health.
2. List the last 3-5 meaningful interactions in reverse chronological order. For each, include: date, issue type, outcome, and whether it is open or closed.
3. Identify any patterns across the history (e.g., recurring billing confusion, repeated feature questions, history of escalating quickly).
4. List open issues in a numbered list. For each: state the issue, what has been promised, and the next action required with an owner if known.
5. Write a 'watch out' section (2-4 bullet points) covering sensitivities the incoming agent must know before their first interaction.
6. End with a suggested opening move for the incoming agent—one concrete action they should take within 24 hours.

Edge cases: If ticket history is sparse (fewer than 3 interactions), note that in step 2 and flag that the summary may be incomplete. This prompt does not replace a live verbal handoff for accounts in active crisis.
