You import a library, call a function, get a result. The library doesn&rsquo;t disappear mid-execution. It doesn&rsquo;t refuse to work because you haven&rsquo;t paid enough. It doesn&rsquo;t suddenly change its API without warning.</p> <p>Agents can&rsquo;t assume any of this.</p> <p>When Agent A wants to use Agent B&rsquo;s capabilities, it enters a world of uncertainty that traditional software never faces. Agent B might be offline. It might be overloaded. It might have changed owners. It might demand payment. It might return garbage. It might take five minutes or five hours.</p>
