Anyone working on AI Agent implementation has likely encountered this dilemma:You're using a flagship model, have revised your prompts hundreds of times, and tuned your RAG system countless times. Yet when deployed in real-world scenarios, the task success rate simply won't improve—the agent sometimes performs brilliantly, other times goes completely off-track.The problem doesn't lie with the model itself, but with the operating system running outside the model—the Harness.What Is Harness Engineering?The term "Harness" originally refers to r...

Codex vs OpenClaw: Understanding the Key Differences in AI Agent Architecture
In the rapidly evolving landscape of AI-powered development tools, practitioners increasingly encounter terms like Codex, OpenClaw, MCP, A2A, Skill, and Harness. These concepts frequently appear together in discussions about AI Agents, leading to considerable confusion about their distinct roles and relationships. This comprehensive analysis clarifies these often-confused concepts within a unified framework.The Fundamental DistinctionThe Essential Takeaway: Codex functions as a specialized intelligent engineer focused on code writing, while ...
