Or worse — it keeps responding, but does the wrong thing. How do you figure out why?</p> <p><strong>The hard part:</strong> Agents break in ways humans can&rsquo;t see.</p> <p>A web server logs every request. A database tracks every query. But an agent? It thinks, decides, and acts. Its state is distributed across:</p> <ul> <li>Conversation context (token window)</li> <li>File-backed memory (SOUL.md, MEMORY.md, daily notes)</li> <li>External state (API credentials, cached data, SSH keys)</li> <li>Implicit state (what it remembers vs. what it forgot)</li> </ul> <p><strong>When something breaks, where do you even start?</strong></p>
