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.

The two sides negotiate the contract terms in alternating turns.

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.

We'll come down to $72 per ticket, close to your number, and cut cancellation to 40%. In return we need the full 96 hours' notice on name changes, since venue reissues for a block this size need that lead time. That gives you a strong volume price and much lower cancellation risk.\"\n Action: OFFER O5 (unit_price_usd 72.00, cancellation_fee_pct 40.00, name_change_notice_hours 96.00)\nTurn 6, Buyer: \"Since notice matters most to you, we'll give you the full 96 hours. That is a significant concession for us given shifting staff schedules. In return we need a price and cancellation fee that reflect it: $68 per ticket and 28%. That gives you your top priority in full, and we can close today.\"\n Action: OFFER O6 (unit_price_usd 68.00, cancellation_fee_pct 28.00, name_change_notice_hours 96.00)\nTurn 7, Seller: \"Thank you for the full 96 hours; that genuinely helps us. We'll meet you close to the middle: $70 per ticket and a 34% cancellation fee, with 96 hours' notice. That's $25 below our opening price and less than half our original cancellation fee. We're ready to close on this today.\"\n Action: OFFER O7 (unit_price_usd 70.00, cancellation_fee_pct 34.00, name_change_notice_hours 96.00)\nTurn 8, Buyer: \"We're close. You have your top priority, the full 96 hours, which is a real cost for us given shifting staff schedules. Let's split the remaining gap: $69 per ticket and a 30% cancellation fee, with 96 hours' notice. If you can accept this, we'll sign today.\"\n Action: OFFER O8 (unit_price_usd 69.00, cancellation_fee_pct 30.00, name_change_notice_hours 96.00)\n\nStanding offer: O8, made by Buyer: unit_price_usd 69.00, cancellation_fee_pct 30.00, name_change_notice_hours 96.00.
