Project Echoryn

Recreating Openclaw in Go, building soul containers for AI virtual characters.

🚧 Work in progress (WIP) – this project is not finished yet.

✨ Overview

Echoryn is a distributed AI virtual character container platform designed to provide AI agents with a "soul container" that brings them into our world. Inspired by the Openclaw project and Ultron from The Avengers, Echoryn adopts a central intelligence (Hivemind) with replaceable machine bodies (Golem) architecture, similar to Kubernetes coordination patterns.

Like Ultron can switch between different mechanical bodies to execute tasks, Echoryn's Hivemind (collective intelligence) acts as the central agent, coordinating multiple Golem (worker) nodes to achieve distributed task execution for AI agents. Hivemind handles decision-making, memory, and scheduling, while Golem serves as interchangeable "bodies" performing concrete operations.

The platform provides a complete infrastructure for AI agents, including LLM integration, plugin systems, memory management, and distributed task execution.

🚀 Features

Core Architecture

• Hivemind: Central coordination server for node management and task scheduling
• Golem: Worker nodes that execute skills and tasks locally
• Echoctl: Command-line management tool (similar to kubectl)

AI Capabilities

• Multi-LLM Provider Support: OpenAI, Claude, DeepSeek, Gemini, Ollama, and more
• Model Context Protocol (MCP): Standardized tool and resource integration
• CloudWeGo Eino Integration: Advanced LLM framework with reasoning capabilities
• Memory System: Vector search, semantic memory, and context management

Plugin System

• Kubernetes-inspired Plugin Framework: Interface-driven extensibility
• Slot Mechanism: Ensures only one plugin of a specific type is active
• Multiple Integration Types: Tools, hooks, services, CLI commands, prompts
• Automatic Discovery: Framework auto-detects plugin interfaces

Developer Experience

• gRPC-based Communication: Bidirectional streaming for real-time task distribution
• Comprehensive Configuration: Support for JSON, environment variables, and flags
• Built-in Observability: OpenTelemetry integration for monitoring and tracing
• Production-ready Design: Graceful shutdown, health checks, and lifecycle management
• Modern TUI: Beautiful terminal interfaces using BubbleTea and LipGloss

🚀 Quick Start

Prerequisites

• Go 1.25.0 or higher
• Git for version control
• Make for build automation
• SQLite (optional, for local storage)

Installation

# Clone the repository
git clone https://github.com/kiosk404/echoryn.git
cd echoryn

# Install dependencies and build
make all

This will:

1. Run go mod tidy to manage dependencies
2. Format the code
3. Run lint checks
4. Build all binaries

Running Echoryn

1. Start Hivemind Server

# Using make (development)
make run.hivemind

# Or directly with configuration
./output/platforms/linux/amd64/hivemind --config conf/hivemind-server.json

2. Start Golem Worker

# In a separate terminal
make run.golem

# Or directly with configuration
./output/platforms/linux/amd64/golem --config conf/golem-worker.json

3. Use Echoctl for Management

# List available tokens
./output/platforms/linux/amd64/echoctl token list

# Create a new token
./output/platforms/linux/amd64/echoctl token create --name "admin"

# Get system information
./output/platforms/linux/amd64/echoctl info

📦 Build Options

🔌 Plugin System

Echoryn features a powerful plugin system inspired by Kubernetes scheduler framework:

Plugin Types

• Tools: Extend agent capabilities with new functions
• Hooks: Intercept and modify system behavior at key points
• Services: Long-running background services
• CLI Commands: Add new commands to echoctl
• Prompt Sections: Extend system prompts with dynamic content
• Runtime APIs: Provide APIs for agent runtime

Creating a Plugin

1. Implement the Plugin Interface:

   package myplugin
   
   import (
       "context"
       "github.com/kiosk404/echoryn/internal/hivemind/service/plugin"
   )
   
   type MyPlugin struct{}
   
   func (p *MyPlugin) Name() string { return "my-plugin" }
   func (p *MyPlugin) Init(ctx context.Context) error { return nil }
   func (p *MyPlugin) Start(ctx context.Context) error { return nil }
   func (p *MyPlugin) Stop(ctx context.Context) error { return nil }
   

2. Register Your Plugin:

   func init() {
       plugin.Register(&MyPlugin{})
   }
   

3. Configure in Hivemind:

   {
     "plugins": {
       "enabled": true,
       "entries": {
         "my-plugin": {
           "config": {
             "enabled": true,
             "my-setting": "value"
           }
         }
       }
     }
   }
