# Agent Runtime Working Mechanism Explained

> Deep dive into Agent Runtime core components and workflow, including event loop, tool scheduling, and context management.

---

## Content

## Overview

Agent Runtime is the execution engine that coordinates all components to work together.

## Core Components

```
┌─────────────┐
│   Runtime   │
├─────────────┤
│ Event Loop  │
│ Tool Router │
│ Context Mgr │
│ LLM Client  │
└─────────────┘
```

## Workflow

1. **Receive Input** → 2. **Load Context** → 3. **LLM Reasoning** → 4. **Tool Call** → 5. **Return Result**

## Event Loop

Runtime uses event-driven architecture to handle concurrent requests for timely responses.

## Tool Scheduling

Automatically matches and calls appropriate tools based on LLM output, supports serial and parallel execution.
