agn 0.4.0
A flexible framework for building multi-agent systems with customizable protocols
License: Apache-2.0
Requires Python: >=3.7

# AGN

> **Note:** This package was previously known as "omniagents". The package has been renamed to "agn" but maintains backward compatibility.

A network-based multi-agent framework where agents connect to a central server for communication and coordination.

## Quick Start

1. Start a network server:
```python
from omniagents.core.network import AgentNetworkServer

# Create and start server
network = AgentNetworkServer(host="127.0.0.1", port=8765)
network.run()
```

2. Connect agents to the server:
```python
from omniagents.core.agent import Agent

# Create and connect agent
agent = Agent(name="MyAgent")
await agent.connect_to_server("127.0.0.1", 8765)

# Send messages to other agents
await agent.send_message("other_agent_id", "Hello!")
```

## Architecture

The framework uses a client-server architecture where:
- A central server manages all agent connections
- Agents connect to the server using WebSocket connections
- All communication between agents goes through the server
- Protocols define message handling behavior

## Overview

OmniAgents provides an engine for running a network with a set of protocols. The framework is designed to be modular, allowing developers to:

1. Create agents with any combination of protocols
2. Establish networks with specific protocol requirements
3. Contribute custom protocols that can be used by other developers

## Features

- **Modular Protocol System**: Mix and match protocols to create the exact agent network you need
- **Flexible Agent Architecture**: Agents can implement any combination of protocols
- **Customizable Communication Patterns**: Support for direct messaging, publish-subscribe, and more
- **Protocol Discovery**: Agents can discover and interact with other agents based on their capabilities
- **Extensible Framework**: Easy to add new protocols and extend existing ones

## Core Protocols

OmniAgents includes several built-in protocols:

| Protocol | Description | Key Features |
|----------|-------------|--------------|
| Discovery | Agent registration and service discovery | Agent registration/deregistration, Service announcement & discovery, Capability advertising |
| Communication | Message exchange between agents | Direct messaging, Publish-subscribe, Request-response patterns |
| Heartbeat | Agent liveness monitoring | Regular status checks, Network health detection |
| Identity & Authentication | Security and identity management | Agent identifiers, Authentication/authorization |
| Coordination | Task distribution and negotiation | Task negotiation & delegation, Contract-net protocol |
| Resource Management | Resource allocation and tracking | Resource allocation & accounting, Usage metering |

## Development and Testing

### Running Tests

You can run the test suite using pytest:

```bash
# Run all tests
pytest

# Run specific test files
pytest tests/test_discoverability.py tests/test_discovery_integration.py

# Run tests with coverage report
pytest --cov=src/omniagents --cov-report=xml
```

### Continuous Integration

This project uses GitHub Actions for continuous integration testing. The workflow automatically runs pytest on Python versions 3.8, 3.9, 3.10, and 3.11 whenever code is pushed to the main, master, or develop branches, or when pull requests are made to these branches.

### Test Status

[![Python Tests](https://github.com/omniagents/omniagents/actions/workflows/pytest.yml/badge.svg)](https://github.com/omniagents/omniagents/actions/workflows/pytest.yml)

### Test Coverage

[![codecov](https://codecov.io/gh/omniagents/omniagents/branch/main/graph/badge.svg)](https://codecov.io/gh/omniagents/omniagents)

### Workflow Details

The CI workflow:
- Runs on multiple Python versions (3.8, 3.9, 3.10, 3.11)
- Installs all dependencies from requirements.txt
- Caches pip dependencies for faster runs
- Runs specific test files focused on discovery and discoverability
- Reports test coverage to Codecov

For more details, see the [workflow configuration file](.github/workflows/pytest.yml).

### Local Development Setup

```bash
# Clone the repository
git clone https://github.com/omniagents/omniagents.git
cd omniagents

# Create and activate a virtual environment (optional but recommended)
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt

# Install the package in development mode
pip install -e .

# Run an example
python examples/example_network.py
```

### Command Line Interface

OmniAgents provides a command-line interface for basic operations:

```bash
# Launch a network with a configuration file
omniagents network launch config.json --runtime 3600

# Get help on available commands
omniagents --help

# Set logging level
omniagents --log-level DEBUG network launch config.json
```

The CLI is currently under development, with more commands planned for future releases. The configuration file should specify the network name, protocols, and other settings.

Example configuration file (config.json):
```json
{
  "name": "MyNetwork",
  "protocols": {
    "discovery": {},
    "communication": {}
  }
}
```
