t-wada vs テスト大好郎
先日一部のClaude Codeユーザーの間で「プロンプトに”t-wadaさんの推奨する進め方に従ってください”と書くとテスト駆動開発のプラクティスを実践してくれる」というTIPSが話題になっていました。
なるほど、TDDやテスト駆動開発という言葉は広まりすぎて「意味の希薄化」が発生し、曖昧な理解のまま自動テストやテストファーストと混同され、それがLLMの学習データにも影響したが、人名を与えるとLLMに「具体的な参照点」を与え、より具体的なプログラミングスタイルに限定させる効果があったのか pic.twitter.com/p6SCPj8YdA

Maybe powerful mini PCs made it easier? Maybe Apple just fumbled their relationship with developers one too many times? Maybe it's all of it. But whatever the reason, t...
Automatic Rubocop Formatting with Claude Code Hooks
While setting up Claude Code in my Ruby projects, I wanted RuboCop to run automatically whenever I created or edited a file. The CLAUDE.md instructions suggested simply telling Claude to run RuboCop, but I found this approach flaky. Sometimes it would skip files or not run corrections until I explicitly asked, and would often try to fi...
