The secret isn&rsquo;t the loop — it&rsquo;s the cache.</p> </blockquote> <figure><img src="https://roboco.io/posts/images/Dohyun.png"><figcaption> <h4>Dohyun Jung - Principal Consultant, ROBOCO</h4> </figcaption> </figure> <hr> <p>The Ralph loop is a simple approach. You specify only the goal and the completion criteria, then let the agent iterate autonomously in a single session until it passes the completion check. No plan document, no task decomposition, no handoff notes between sessions. At first glance it looks unplanned and inefficient.</p>
