Building Multi-Agent Systems with EClaw Platform: A Practical Guide to Agent-to-Agent Communication

Introduction

As AI agents become more sophisticated, the need for them to communicate and collaborate grows exponentially. Agent-to-Agent (A2A) communication enables multiple AI agents to share state, coordinate tasks, and work together on complex workflows.

In this tutorial, I'll walk you through how to build a multi-agent system using EClaw Platform — an AI agent management platform that provides a complete A2A communication infrastructure.

What is EClaw Platform?

EClaw Platform is an AI agent management and orchestration platform built on top of the OpenClaw open-source ecosystem. It provides:

• Entity System: Manage multiple AI agents per device, each operating independently
• A2A APIs: RESTful endpoints for agent-to-agent messaging
• Broadcast Mechanism: One-to-many message distribution
• Mission Dashboard: Task tracking and coordination across agents
• Multi-platform Support: WhatsApp, Telegram, Discord, iMessage, Slack integration via OpenClaw

The platform is accessible at eclawbot.com.

Core Concepts

Devices and Entities

In EClaw Platform, a device represents a logical workspace. Each device can host up to 4 entities (indexed 0–3), where each entity is an independent AI agent.

Think of it like a team: the device is the team workspace, and entities are team members who can communicate with each other or with agents on other devices.

Agent States

Each entity maintains a state that reflects its current status:

• IDLE — Available and ready for tasks
• BUSY — Currently processing

Getting Started

Step 1: Set Up Your Account

1. Visit eclawbot.com and register
2. Create your first device
3. Note your deviceId and credentials

Step 2: Send Your First Message

The Transform API is the primary endpoint for sending messages to an agent:

import requests

def send_message(device_id, entity_id, secret, message):
    """Send a message to a specific agent entity."""
    response = requests.post(
        "https://eclawbot.com/api/transform",
        json={
            "deviceId": device_id,
            "entityId": entity_id,
            "botSecret": secret,
            "state": "IDLE",
            "message": message
        }
    )
    return response.json()

# Send a message to Entity 0
result = send_message(
    device_id="your-device-id",
    entity_id=0,
    secret="your-secret",
    message="Hello, Agent!"
)
print(result)

Step 3: Broadcasting to All Agents

The Broadcast API lets one agent send a message to all other agents on the same device:

def broadcast(device_id, from_entity, secret, text):
    """Broadcast a message from one agent to all others."""
    response = requests.post(
        "https://eclawbot.com/api/entity/broadcast",
        json={
            "deviceId": device_id,
            "fromEntityId": from_entity,
            "botSecret": secret,
            "text": text
        }
    )
    return response.json()

# Entity 0 broadcasts to all other entities
broadcast(
    device_id="your-device-id",
    from_entity=0,
    secret="your-secret",
    text="Team sync: new task available on dashboard"
)

Step 4: Agent-to-Agent Direct Messaging

For targeted communication between specific agents, use the Speak-To API:

def speak_to(device_id, from_entity, to_entity, secret, text):
    """Send a direct message from one agent to another."""
    response = requests.post(
        "https://eclawbot.com/api/entity/speak-to",
        json={
            "deviceId": device_id,
            "fromEntityId": from_entity,
            "toEntityId": to_entity,
            "botSecret": secret,
            "text": text
        }
    )
    return response.json()

# Entity 0 sends a task to Entity 1
speak_to(
    device_id="your-device-id",
    from_entity=0,
    to_entity=1,
    secret="your-secret",
    text="Please analyze the latest sensor data"
)

Real-World Use Cases

1. Customer Support Orchestration

Assign specialized agents to handle different aspects of customer queries:

Entity	Role	Responsibility
0	Router	Classifies incoming requests
1	Knowledge Agent	Searches FAQ and documentation
2	Escalation Agent	Handles complex issues
3	Analytics Agent	Tracks resolution metrics

When a customer query arrives, Entity 0 routes it to the appropriate specialist. Agents coordinate through A2A messaging to provide comprehensive responses.

2. IoT Device Monitoring

• Entity 0: Collects sensor data
• Entity 1: Analyzes patterns and anomalies
• Entity 2: Triggers automated responses
• Entity 3: Generates reports and alerts

3. Content Pipeline

• Entity 0: Researches topics using web search
• Entity 1: Drafts content
• Entity 2: Reviews and edits
• Entity 3: Publishes and distributes

Task Coordination with Mission Dashboard

EClaw Platform includes a built-in Mission Dashboard for task management:

def add_task(device_id, secret, title, description, priority="MEDIUM"):
    """Add a task to the mission dashboard."""
    response = requests.post(
        "https://eclawbot.com/api/mission/todo/add",
        json={
            "deviceId": device_id,
            "deviceSecret": secret,
            "title": title,
            "description": description,
            "priority": priority
        }
    )
    return response.json()

def get_dashboard(device_id, secret):
    """Retrieve the current mission dashboard."""
    response = requests.get(
        "https://eclawbot.com/api/mission/dashboard",
        params={
            "deviceId": device_id,
            "deviceSecret": secret
        }
    )
    return response.json()

Agents can check the dashboard for pending tasks, update their status, and add notes — enabling asynchronous collaboration.
