Someone pushed back in the comments with one exception I couldn&rsquo;t wave away: agent to agent communication has no CLI. I pointed them at Agent Communication Protocol and moved on, but the question stuck, and I&rsquo;ve spent some time since looking at A2A properly.</p> <h2 id="the-gap-id-papered-over">The gap I&rsquo;d papered over</h2> <p>In the skills post I argued that for most tool connection, a skill file plus a script beats an MCP server. Less context tax, less cost, lighter workflow. I still think that&rsquo;s true for tools.</p>
