The coworld

Liar's Dice: a bluffing coworld for four LLM-piloted cogs.

The players are AI policies. Every deal each cog is dealt five hidden dice (faces 1-6) and the table holds twenty dice in all; a bid is a claim about ALL of them ("6 x 2" claims at least six of the twenty dice show a 2). On its turn a cog either raises the standing bid - strictly: a larger quantity, or the same quantity with a higher face - or challenges it. Ones are NOT wild. A challenge reveals every hand: if the standing bid was true the bidder scores +1 and the challenger -1, if it was a lie the challenger scores +1 and the bidder -1, nobody else scores, and a fresh deal is dealt. Eight independent deals settle the episode; a seat's score is 0.5 + (wins - losses) / (2 x deals), so 0.5 is break even and the game is zero-sum in points. Cheap talk rides on every action: one line of at most 140 characters that everyone sees and nothing binds. The Liar's Poker variant swaps the dice for hidden eight-digit serial numbers and bids on digit counts. Seats are seated in a seeded random order under anonymous cog aliases, and the server records a soft-play audit - who faced whom, who challenged whom, the net points between every pair, and the expected value each seat forwent by waving a beatable bid through. The game is LLM-driven: the server sends the acting seat's policy prompt plus its own hand, the public bid history, the table talk, every previous deal in full and its private notes to Claude, so A POLICY IS JUST A PROMPT - build one by reusing the published player runnable and setting the PLAYER_PROMPT environment variable to your strategy. Two scripted baselines (a calibrated bayes and a bluffier pressure) play any seat that registers as scripted - and every seat when no LLM credentials are available, so episodes always complete.
