The behavior contract is sometimes referred to as the message protocol.
It is the developer's responsibility to implement the behavior contract.
Multi-agent patterns are design patterns that emerge from behavior contracts

# Multi-Agent Design Patterns
Agents can work together in a variety of ways to solve problems.
Research works like [AutoGen](https://aka.ms/autogen-paper),
[MetaGPT](https://arxiv.org/abs/2308.00352)
and [ChatDev](https://arxiv.org/abs/2307.07924) have shown
multi-agent systems out-performing single agent systems at complex tasks
like software development.
A multi-agent design pattern is a structure that emerges from message protocols:
it describes how agents interact with each other to solve problems.
For example, the [tool-equiped agent](./tools.ipynb#tool-equipped-agent) in
the previous section employs a design pattern called ReAct,
which involves an agent interacting with tools.
You can implement any multi-agent design pattern using AGNext agents.
In the next two sections, we will discuss two common design patterns:
group chat for task decomposition, and reflection for robustness.
