<h3>Overview</h3>
<p>The <code>@drupal-canvas/create</code> package's agent metadata and selection flow need to reflect the current set of supported coding agents and their skills directory behavior.</p>
<p>Several agents that use the shared <code>.agents/skills</code> directory are still treated as agent-specific, and some newer agents are not yet included in the available options.</p>
<h3>Proposed resolution</h3>
<p>Update <code>packages/create/src/lib/agents.ts</code> to align with the agent list and shared skills directory behavior in <a href="https://github.com/vercel-labs/skills"><code>vercel-labs/skills</code></a>.</p>
<p>This includes:</p>
<ul>
<li>Adding newly supported agents such as <code>cortex</code>, <code>deepagents</code>, and <code>warp</code>.</li>
<li>Reclassifying agents like <code>antigravity</code>, <code>cline</code>, and <code>cursor</code> to use <code>.agents/skills</code>.</li>
<li>Updating related tests so compatibility symlinks are only created for truly non-universal agents.</li>
<li>Refreshing agent-selection copy in the create package to use the newer “additional agents” wording and clearer compatibility setup messages.</li>
</ul>
<h3>User interface changes</h3>
<p>The interactive agent-selection prompt in the create flow is updated to:</p>
<ul>
<li>Clarify that universal agents are always included.</li>
<li>Rename the selectable section from “Other agents” to “Additional agents.”</li>
<li>Use updated wording in related status and setup messages.</li>
</ul>
