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.
