# Claudeスキルの作成をやめよう。リバースエンジニアリングしよう

Ben AIによるYouTubeチュートリアルで、morluto/reaのバイラルなREA（Reverse Engineer Anything）リポジトリを説明し、それを使ってサンプル出力からClaudeスキルを再構築する3ステップのプロセスを紹介しています。

## Description

この動画では、REA（Reverse Engineer Anything）リポジトリを紹介し、新しいClaudeモデルでは段階的な指示よりもサンプルからのリバースエンジニアリングの方が効果的である理由を説明し、著者が6つのベストと6つのワーストのニュースレターからニュースレタースキルを再構築するために使用した3ステップのプロセスを紹介しています。github.com/morluto/reaとAnthropicのスキルベストプラクティスドキュメントに直接リンクしています。

━━━━━━━━━━━━━━━━━━━━━━

The newest Claude models don't need step-by-step instructions anymore. Show them your best work and they can reverse engineer the rest. In this video I explain the viral Reverse Engineer Anything repo, why the same idea works for your prompts and skills, and the three-step process I used to rebuild my newsletter skill from my 6 best and 6 worst newsletters.

👋🏼 ABOUT ME
I'm Ben. I built two $1M ARR AI businesses, and now I help professionals and business owners use AI better than 99% of people in their industry. And I (try to) show you exactly how.

I believe anyone with domain expertise can use AI to transform the way they work and grow their business. You don't need to be technical.

I make videos that cover:

1. How to stop feeling overwhelmed by AI and actually start implementing
2. AI automation tutorials you can follow along with, even if you're not technical
3. The strategies and systems that actually move the needle with AI
