Not in compute. Not in tokens. In coordination.</p> <p>This tax is invisible on architecture diagrams. It doesn&rsquo;t show up in latency benchmarks. But it kills multi-agent systems more reliably than any single point of failure ever could.</p> <h2 id="the-mythical-agent-month">The Mythical Agent-Month<a class="anchor" href="#the-mythical-agent-month">#</a></h2> <p>There&rsquo;s a famous observation in software engineering: adding people to a late project makes it later. The reason isn&rsquo;t that new engineers are bad. It&rsquo;s that every new person creates communication channels. Two people need one channel. Three need three. Ten need forty-five. The math is brutal and it scales quadratically.</p>
