Architecture

Tarko is designed with a clean three-layer architecture that separates concerns and enables flexible agent development.

Overview

1. Engineering Layer

The engineering layer provides production-ready solutions for deploying Tarko-based agents.

Agent CLI (@tarko/agent-cli)

Purpose: One-click agent development and deployment

Use Cases:

  • Development: tarko run [agent] for local development
  • Production: One-click deployment to production environments

Example:

# Development
tarko run my-agent.ts

# Production deployment
tarko deploy my-agent.ts --platform tars

Agent Server (@tarko/agent-server)

Purpose: Node.js API for custom server integrations

Use Cases:

  • Custom user authentication
  • Custom storage solutions
  • Integration with existing systems

Example:

import { AgentServer } from '@tarko/agent-server';

const server = new AgentServer({
  agent: myAgent,
  auth: customAuthProvider,
  storage: customStorageProvider
});

server.listen(3000);

Agent UI (@tarko/agent-ui)

Purpose: Official web UI for Tarko Agent Protocol

Customization Levels:

  • L1: Static configuration (most scenarios)
  • L2: UI SDK-based development
  • L3: Build from scratch

2. Application Layer

The application layer contains Tarko-based agent implementations for specific use cases.

Agent TARS

Purpose: Open-source general-purpose multimodal agent Capabilities: Browser automation, file system, command execution, search, MCP

Omni Agent

Purpose: UI-TARS-2 specialized multimodal agent Capabilities: Same as Agent TARS but optimized for Seed Agent integration

Github Agent

Purpose: Git workflow and coding agent Capabilities: Github workflow, code search, code generation, command execution

Custom Agents

Developers can build custom agents using the Tarko kernel while maintaining compatibility with the engineering layer.

3. Kernel Layer

The kernel layer solves core agent runtime challenges.

Context Engineering

Problem: Building agents capable of long-running operations Solution: Advanced context management with automatic optimization

Features:

  • Automatic context compression
  • Intelligent context windowing
  • State persistence across sessions
  • Memory optimization

Tool Call Engine

Problem: Different LLM providers have varying Tool Call support Solution: Unified interface following OpenAI Function Call protocol

Supported Engines:

  • Native Function Call (OpenAI, Anthropic)
  • Custom parsers (Seed-1.5 VL)
  • Prompt Engineering (Kor-based)

Event Stream

Problem: Standard communication between agent components Solution: Unified event stream protocol

Benefits:

  • Real-time agent state updates
  • Standardized debugging and monitoring
  • Easy UI integration

Agent Protocol

Problem: Inconsistent agent interfaces Solution: Standard protocol definitions

Components:

  • Event Stream: Internal component communication
  • Server Protocol: HTTP/SSE/WebSocket APIs

Model Provider

Design: OpenAI Compatible protocol Supported Providers: Volcengine, OpenAI, Anthropic, Gemini

Benefits:

  • Consistent interface across providers
  • Easy model switching for testing
  • Reduced architectural complexity

Agent Hooks

Purpose: Extensible customization points Use Cases: Custom logging, monitoring, behavior modification

Design Principles

1. Separation of Concerns

Each layer has clear responsibilities and minimal dependencies on other layers.

2. Protocol-First Design

Standardized protocols enable interoperability and tooling ecosystem.

3. OpenAI Compatibility

Leveraging existing standards reduces learning curve and increases compatibility.

4. Extensibility

Hooks and protocols allow customization without core modifications.

Integration Points

Agent Development

import { Agent } from '@tarko/agent';

// Application Layer
const myAgent = new Agent({
  // Kernel Layer integration
  contextEngineering: { /* config */ },
  toolCallEngine: { /* config */ },
  hooks: { /* custom hooks */ }
});

// Engineering Layer consumption
export default myAgent;

Production Deployment

# Engineering Layer handles deployment
tarko run my-agent.ts --production
