Thoughts were turned into spoken language, language was turned into writing, writing came to be printed at massive scale, and all of that was eventually transformed into digital artifacts stored in computers.</p> <p>These transitions allowed humanity to reorganize its mental capacity, freeing up limited space to focus on planning, abstraction, and creativity.</p> <p>There is an argument that this same logic can be applied to the design and development of LLM-based agents, and that the improvement in these agents is not mainly driven by training ever-larger models. It comes, instead, from reallocating the model&rsquo;s cognitive load into persistent, inspectable, and reusable structures, organized into three main pillars mediated by a concept called Harness Engineering.</p>
