<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>Field Widget Action plugins (<code>@FieldWidgetAction</code>) provide AI-powered actions on field widgets in entity forms, such as auto-generating content, suggesting values, or transforming field data. These are a key integration point between the AI module and Drupal's content editing experience.</p>
<p>An agent skill and Drush generator would help developers quickly create custom field widget actions for their specific field types and use cases.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<ul>
<li>Create <code>.agent/skills/create-field-widget-action/SKILL.md</code> describing how to create a Field Widget Action plugin, including the <code>@FieldWidgetAction</code> attribute, the <code>FieldWidgetActionInterface</code>, and how to target specific field types and widgets.</li>
<li>Include a complete working example of a field widget action plugin.</li>
<li>Add a Drush generate command (<code>drush generate ai-field-widget-action</code>) that scaffolds the plugin class.</li>
<li>Reference the existing field widget actions documentation under <code>docs/modules/field_widget_actions/</code>.</li>
</ul>
