GoodOverview
This guide covers the core principles, architecture, and implementation of Agent Harness systems, summarizing the philosophy that an Agent equals a large language model combined with a Harness. Using three major production reference systems—OpenCodex, Claude Code, and OpenClaw—alongside a hands-on Python project called MiniHarness, the resource explores runtime engines, tool layers, memory subsystems, task orchestration, Model Context Protocol (MCP) integration, security models, and reliability engineering.
Capabilities
- ▸Runtime engine design and error recovery
- ▸Tool abstraction and execution pipelines
- ▸Memory subsystem and context assembly
- ▸Task orchestration and multi-agent workflows
- ▸Model Context Protocol (MCP) integration
- ▸Sandboxing and security barrier implementation
Best for
Designing and building custom agent runtime engines and execution loops, Implementing robust tool execution pipelines, dynamic discovery, and permission controls, Building multi-layered memory architectures and context management engines, Integrating the Model Context Protocol (MCP) into agent harness systems, Architecting sandboxing, security barriers, and verification loops for AI agents
