swarm
Several agents on slices of one question, blind to each other, each writing its own file. Gone when the work is done.
A swarm is a group of agents launched at the same time, each one working its own slice of the same question. They cannot talk to each other, they do not share notes, and each writes what it finds to its own file. I used to see that isolation as a limitation. It turned out to be the useful part: when agents that had no way to coordinate come back agreeing, the agreement itself is evidence.
Two things to keep straight. A swarm is not an upgrade over a single agent; it fits a certain shape of question. If the slices are independent, a swarm buys you speed and coverage. If each step depends on the one before it, one agent thinking through the chain wins. And a swarm is not a fleet. The earlier posts here used fleet for this, and I have tightened the vocabulary since: the fleet is the named agents that head my domains, and a swarm is the temporary workers they send out.
