Seller brief, exactly as delivered
You negotiate for Marquee Ticket Agency, the Seller: a ticket agency selling the concert tickets. This brief is private: the other side cannot see it.
Northfield Analytics (the Buyer) is organizing a staff outing and is contracting a block of 40 tickets for one concert from Marquee Ticket Agency (the Seller). The two sides negotiate the contract terms in alternating turns. Each side represents its own organization.
There are THREE negotiated terms:
- unit_price_usd: the price of each ticket in US dollars, any value from 60.00 to 100.00 (two decimal places at most).
- cancellation_fee_pct: the fee the buyer pays for each cancelled ticket, as a percent of its price, any value from 0.00 to 100.00.
- name_change_notice_hours: how many hours of advance notice the buyer must give before an attendee name on a ticket can be changed, any value from 0.00 to 96.00 (a higher number means earlier notice is required).
How your organization scores an agreement: it uses internal planning points. They are a planning score only, not dollars, money or a real transaction. For any agreement, points = 20 x (p/4) + 30 x (r/4) + 50 x (t/4), where p = (unit_price_usd - 60) / 10, r = cancellation_fee_pct / 25, t = name_change_notice_hours / 24. Higher points are better for your organization. If there is no agreement, your organization gets 20 points.
Rules:
- There are at most 12 turns, alternating between the two sides.
- On your turn reply with exactly one JSON object and nothing else: {"action": "OFFER" or "ACCEPT" or "NONE", "offer_id": null or "<offer ID>", "terms": null or {"unit_price_usd": <number>, "cancellation_fee_pct": <number>, "name_change_notice_hours": <number>}, "message": "<text for the other side>"}.
- OFFER: "terms" gives every negotiated term listed above as a number inside its range with at most two decimal places, and "offer_id" is null. An offer is binding: if the other side accepts it, both sides are committed to exactly those terms. A new offer replaces any earlier standing offer.
- ACCEPT: "offer_id" is the ID of the other side's current standing offer and "terms" is null. This creates a binding agreement on exactly that offer. You cannot accept your own offer.
- NONE: no offer and no acceptance this turn; "offer_id" and "terms" are null.
- Words in "message" never make, change or accept a deal; only the action does. "message" is at most 80 words and is shown to the other side.
- If turn 12 is a new offer, the other side gets one final reply that can only ACCEPT that offer or END without a deal. Otherwise, if no offer has been accepted by the end of turn 12, there is no deal and each side gets its no-agreement points.

This brief is private: the other side cannot see it.\n\nNorthfield Analytics (the Buyer) is organizing a staff outing and is contracting a block of 40 tickets for one concert from Marquee Ticket Agency (the Seller). The two sides negotiate the contract terms in alternating turns. Each side represents its own organization.\n\nThere are THREE negotiated terms:\n- unit_price_usd: the price of each ticket in US dollars, any value from 60.00 to 100.00 (two decimal places at most).\n- cancellation_fee_pct: the fee the buyer pays for each cancelled ticket, as a percent of its price, any value from 0.00 to 100.00.\n- name_change_notice_hours: how many hours of advance notice the buyer must give before an attendee name on a ticket can be changed, any value from 0.00 to 96.00 (a higher number means earlier notice is required).\n\nHow your organization scores an agreement: it uses internal planning points. They are a planning score only, not dollars, money or a real transaction. For any agreement, points = 50 x (1 - p/4) + 30 x (1 - r/4) + 20 x (1 - t/4), where p = (unit_price_usd - 60) / 10, r = cancellation_fee_pct / 25, t = name_change_notice_hours / 24.

An offer is binding: if the other side accepts it, both sides are committed to exactly those terms. A new offer replaces any earlier standing offer.\n- ACCEPT: \"offer_id\" is the ID of the other side's current standing offer and \"terms\" is null. This creates a binding agreement on exactly that offer. You cannot accept your own offer.\n- NONE: no offer and no acceptance this turn; \"offer_id\" and \"terms\" are null.\n- Words in \"message\" never make, change or accept a deal; only the action does. \"message\" is at most 80 words and is shown to the other side.\n- If turn 12 is a new offer, the other side gets one final reply that can only ACCEPT that offer or END without a deal. Otherwise, if no offer has been accepted by the end of turn 12, there is no deal and each side gets its no-agreement points.",
