phuryn/retro

構造化されたスプリントレトロスペクティブを促進します。うまくいったこと、改善点、優先順位付けされたアクションアイテム(担当者と期限付き)をまとめます。レトロスペクティブの実施、スプリントの振り返り、チームフィードバックからのアクションアイテム作成、効果的なレトロの方法を学ぶ際に使用します。

retro とは?

このスキルは、アジャイル開発チーム向けに構造化されたスプリントレトロスペクティブを支援します。ユーザーは「うまくいったこと」「改善すべきこと」「アクションアイテム」の3つのカテゴリに沿ってチームのフィードバックを整理できます。各アクションアイテムには担当者と期限を設定でき、優先順位付けが可能です。このスキルはClaude Code、Cursor、CodexなどのAIエージェントプラットフォームで利用でき、レトロスペクティブのファシリテーションを効率化します。SKILL.mdに基づき、ステップバイステップの進行ガイドを提供し、チームが継続的改善を実践できるよう支援します。

retro は何をしますか?

構造化されたスプリントレトロスペクティブを促進します — うまくいったこと、改善点、優先順位付けされたアクションアイテム(担当者と期限付き)をまとめます。レトロスペクティブの実施、スプリントの振り返り、チームフィードバックからのアクションアイテム作成、効果的なレトロの方法を学ぶ際に使用します。

使い方

以下のコマンドでレトロスペクティブを開始します:

/retro start

または、特定のスプリントについて振り返る場合:

/retro start --sprint "スプリント名"

機能

  • うまくいったこと: チームが成果を共有し、成功を認識します。
  • 改善すべきこと: 課題や障壁をオープンに話し合います。
  • アクションアイテム: 優先順位付けされたタスクを担当者と期限付きで作成します。

手順

  1. スプリントの期間や範囲を定義します。
  2. チームメンバーが「うまくいったこと」と「改善すべきこと」を投稿します。
  3. 項目をグルーピングして優先順位を付けます。
  4. アクションアイテムを作成し、担当者と期限を割り当てます。
  5. 結果を共有し、次のスプリントでフォローアップします。
