MV-inspired game built in Unity. @ruku_practice made this with Claude Opus 5.5 and shared the prompt; it is quoted below word for word. The video runs 54s and had 18.4K views on X. Copy the prompt or download it as a SKILL.md, then swap in your own product, brand or topic.

The prompt

MVの0:43〜46の動きを再現して欲しいのでもっと研究してください。 その上で、 実装 → 実際にゲームを起動 → プレイ → スクリーンショット確認 → 厳格なVisual QA → 改善 を繰り返してください。 評価は非常に厳しくしてください。「デモだから十分」「動くからOK」と判断してはいけません。Steamで販売されている高品質なインディーRPGと並べても見劣りしないレベルを目標にしてください。 必要に応じてベンチマークとなるゲーム（ロックマン11、プレイ動画：https://www.youtube.com/watch?v=Uc8Y_0kQ1ho）を調査し、情報密度、色彩、キャラクターの視認性、マップ、UI、アニメーション、戦闘演出を評価してください。ただし素材やデザインをコピーしてはいけません。 プレースホルダー、絵文字、単純な色付き四角形、未実装ボタン、TODOを最終成果物に残さないでください。 最優先するのはゲームの規模ではなく完成度です。 「技術デモ」ではなく、「この続きを遊びたいと思える市販インディーRPGの体験版」に見えるまで改善を続けてください。 ultracodeやサブエージェントなど利用可能な高性能な開発機能があれば積極的に使用してください。
