主なハイライト

Storybook Connect: IDE を離れることなく AI 支援でストーリーを管理。

ストーリーブックは最新である場合にのみ役に立ち、その状態を維持するには非常に手間がかかるため、通常は最新になっていません。Storybook Connect はストーリーが関連付けられていないコンポーネントを検出し、AI エージェントを使用して TypeScript のプロパティからストーリーを生成する新しいプラグインです。手動でプロンプトを作成する必要はありません。

このプラグインにはスキルとツールも含まれるため、エージェントが最初からコンポーネントライブラリを理解し、プロジェクト内での再利用性と精度を強化できるようになっています。Storybook Connect は WebStorm、PhpStorm、IntelliJ IDEA、およびその他の IDE に対応しています。
