How Harness Engineering Creates AI Agents

<p>Most developers have heard of prompt engineering. Many know about context engineering and RAG. But the real frontier in AI today is harness engineering — the structured environment that transforms an ordinary LLM into a powerful agentic system. In this episode of the Code to Care series, I walk through the complete evolution of how developers have learned to work with large language models (LLMs): from the early days of prompt engineering, through the rise of context engineering and RAG (Retrieval Augmented Generation), and into today&#39;s most powerful paradigm harness engineering.</p><p><br></p><p>Ref: https://www.youtube.com/watch?v=yg55OIb5op0</p>
