Multi-agent system
Several agents that divide a task between them and exchange work through a protocol.
A multi-agent system is a set of agents that divide a task between them, for example one agent that plans a purchase, another that compares offers and another that handles payment. The agents exchange tasks and results through a protocol such as Agent2Agent, often without seeing each other's internal logic. Each hand-off is a point where authority, identity and logging must be carried forward, or the chain of responsibility breaks.
