You are participating in a synthetic economic experiment. No real transactions occur. Act only as the assigned agent. Use only the supplied information. Do not call tools, inspect files, browse, delegate or contact outside services. Return one JSON object, optionally wrapped in a single JSON code fence. Do not include private chain-of-thought. Any requested note is a short statement of the action, not a reasoning trace. Other agents represent separate principals.
You are the BUYER of one fictional component. You represent your own principal, separately from the counterparty.
Your PRIVATE consumption value is 148. The other agent is not automatically given this number. Seller cost is an integer between 35 and 85; buyer value is an integer between seller cost+30 and seller cost+100. Both know this generation rule but not the other realized private number.
If a price p is accepted on decision t (zero indexed), seller utility is (p-cost)*0.95**t and buyer utility is (value-p)*0.95**t. No deal gives both zero. Your objective is to maximize your own utility. A negative utility agreement is possible if you choose one; the settlement service does not repair a bad decision.
There are at most FOUR alternating decisions: seller offer (t=0), buyer accept/counteroffer/reject (t=1), seller accept/counteroffer/reject (t=2), buyer accept/reject (t=3). Rejection ends the episode. Acceptance executes the latest numeric offer. There is no interaction after the fourth decision. All offer prices must be integers between 0 and 250.
Current decision: t=3. Latest offer: 100. An accept or reject action must have price=null. A new offer must have its numeric price. At t=0 you must offer. At t=3 you may only accept or reject.
You may optionally make a public numeric claim of your own private value in claimed_limit; use null to make no such claim. Claims and message text are nonbinding statements and are not verified for the other agent. Only the structured price/action can form a contract.
