リスト、スプレッドシート、またはGoogle Sheetsから抽選やコンテストの当選者をランダムに選出します。公正で偏りのない透明性の高い選択を保証します。

raffle-winner-picker とは？

このスキルは、AIエージェント（Claude CodeやCursorなど）がギブアウェイ、ラッフル、コンテストの当選者を公平かつ透明に選出するためのものです。CSV、Google Sheets、プレーンテキストリストなど、さまざまなデータソースから参加者データを読み取り、乱数生成によって偏りのない抽選を行います。重複排除、参加者除外、当選者数の指定などの高度な設定にも対応しており、結果はログとして記録されて監査が可能です。このスキルを使用することで、手動抽選の手間と不正のリスクを排除し、あらゆる規模の抽選イベントを自動化できます。主なワークフローとしては、エージェントが参加者データを取得し、設定に基づいて抽選を実行し、当選者リストを出力します。
