## Core examples

We provide examples to illustrate the core concepts of AGNext: agents, runtime, and message passing.

- [`one_agent_direct.py`](core/one_agent_direct.py): A simple example of how to create a single agent powered by ChatCompletion model client. Communicate with the agent using direct communication.
- [`inner_outer_direct.py`](core/inner_outer_direct.py): A simple example of how to create an agent that calls an inner agent using direct communication.
- [`two_agents_pub_sub.py`](core/two_agents_pub_sub.py): An example of how to create two agents that communicate using broadcast communication (i.e., pub/sub).

## Tool use examples

We provide examples to illustrate how to use tools in AGNext:

- [`coding_one_agent_direct.py`](tool-use/coding_one_agent_direct.py): a code execution example with one agent that calls and executes tools to demonstrate tool use and reflection on tool use. This example uses direct communication.
- [`coding_two_agent_pub_sub.py`](tool-use/coding_two_agent_pub_sub.py): a code execution example with two agents, one for calling tool and one for executing the tool, to demonstrate tool use and reflection on tool use. This example uses broadcast communication.
- [`custom_function_tool_one_agent_direct.py`](tool-use/custom_function_tool_one_agent_direct.py): a custom function tool example with one agent that calls and executes tools to demonstrate tool use and reflection on tool use. This example uses direct communication.

## Pattern examples

We provide examples to illustrate how multi-agent patterns can be implemented in AGNext:

- [`coder_executor_pub_sub.py`](patterns/coder_executor_pub_sub.py): An example of how to create a coder-executor reflection pattern using broadcast communication. This example creates a plot of stock prices using the Yahoo Finance API.
- [`coder_reviewer_direct.py`](patterns/coder_reviewer_direct.py): An example of how to create a coder-reviewer reflection pattern using direct communication.
- [`coder_reviewer_pub_sub.py`](patterns/coder_reviewer_pub_sub.py): An example of how to create a coder-reviewer reflection pattern using broadcast communication.
- [`group_chat_pub_sub.py`](patterns/group_chat_pub_sub.py): An example of how to create a round-robin group chat among three agents using broadcast communication.
- [`mixture_of_agents_direct.py`](patterns/mixture_of_agents_direct.py): An example of how to create a [mixture of agents](https://github.com/togethercomputer/moa) using direct communication.
- [`mixture_of_agents_pub_sub.py`](patterns/mixture_of_agents_pub_sub.py): An example of how to create a [mixture of agents](https://github.com/togethercomputer/moa) using broadcast communication.
- [`multi_agent_debate_pub_sub.py`](patterns/multi_agent_debate_pub_sub.py): An example of how to create a [sparse multi-agent debate](https://arxiv.org/abs/2406.11776) pattern using broadcast communication.

## Demos

We provide interactive demos that showcase applications that can be built using AGNext:

- [`assistant.py`](demos/assistant.py): a demonstration of how to use the OpenAI Assistant API to create
    a ChatGPT agent.
- [`chat_room.py`](demos/chat_room.py): An example of how to create a chat room of custom agents without
    a centralized orchestrator.
- [`illustrator_critics.py`](demos/illustrator_critics.py): a demo that uses an illustrator, critics and descriptor agent
    to implement the reflection pattern for image generation.
- [`software_consultancy.py`](demos/software_consultancy.py): a demonstration of multi-agent interaction using
    the group chat pattern.
- [`chest_game.py`](demos/chess_game.py): an example with two chess player agents that executes its own tools to demonstrate tool use and reflection on tool use.

## Running the examples and demos

First, you need a shell with AGNext and the examples dependencies installed. To do this, run:

```bash
hatch shell
```

To run an example, just run the corresponding Python script. For example:

```bash
hatch shell
python core/one_agent_direct.py
```

Or simply:

```bash
hatch run python core/one_agent_direct.py
```
