Design handoff boundaries before adding more agents

More agents do not improve a workflow if nobody defines where one responsibility ends and the next begins.

The easiest way to create noisy multi-agent systems is to keep adding specialists without defining where each handoff becomes legal. More participants only amplify ambiguity when the workflow has no enforced edges.

Good handoffs are narrow. They say what state is allowed to move, what evidence must already exist, and what permissions the next actor receives.

Boundary questions that matter

• What exactly is being handed off: data, authority, or both?
• What state must exist before the next stage can begin?
• What prevents an agent from skipping ahead or re-entering an older stage?

Workflow scale works when transition legality is enforced. Otherwise the extra agents just multiply drift.
