JKK URL Scout adds a Tools page that exports a list of post/page URLs (and related metadata) to a CSV file.
It is designed for large sites:
<ul>
<li>Exports in batches to reduce timeouts and memory usage.</li>
<li>No external requests, no tracking/telemetry.</li>
<li>Admin-only actions protected with capability checks and nonces.</li>
</ul>
The CSV includes common fields such as:
<ul>
<li>Post ID, post type, status, dates</li>
<li>Title, slug, parent ID, comment count</li>
<li>Permalink and edit link</li>
<li>Categories, tags</li>
<li>Author display name</li>
<li>Featured image URL</li>
<li>Page template</li>
</ul>
<h3>Notes (Japanese)</h3>
本プラグインは WordPress 管理画面の「ツール」配下に CSV エクスポート画面を追加し、投稿/固定ページ/カスタム投稿タイプの URL 一覧を CSV で出力します。 
大量件数のサイトでも動作しやすいよう、バッチ処理（分割取得）でのエクスポートを前提にしています。
