Skills are custom instructions that extend Claude's capabilities for specific tasks or domains. When you create a skill via a SKILL.md file, you're teaching Claude how to handle specific scenarios more effectively. The power of skills lies in their ability to encode institutional knowledge, standardize outputs, and handle complex multi-step workflows that would otherwise require repeated explanati

はじめに この記事では Claude Code を利用してアプリを開発する過程を共有します。 TL;DR GitHub の任意リポジトリを入力すると、スターを付けたユーザの所在地を世界地図にプロットする Web アプリを作りました。 デモ : https://geostarmap.pages.dev/ リポジトリ：https://github.com/yottahmd/geostarmap なぜ作ったか OSS を開発していると「どの国の開発者に届いているのか」が気になってきます。しかし既存のソフトウェアは、Pythonでローカルで動かす必要があったり、メンテされておらず動かないなどの問題がありました。 そこで「Claude Code に作らせたら、一瞬でできるのでは？」という実験を兼ねて、自分で最小構成のアプリを構築することにしました。 短時間で作った実験アプリなので品質は重視しておりま
April 25, 2022 Four Eras of JavaScript Frameworks April 25, 2022 I started coding primarily in JavaScript back in 2012. I had built a PHP app for a local business from the ground up, a basic CMS and website, and they decided that they wanted to rewrite it and add a bunch of features. The manager of the project wanted me to use .NET, partially because it’s what he knew, but also because he wanted i

CORS is a necessity for many APIs, but basic configurations can create a huge number of extra requests, slowing down every browser API client, and sending unnecessary traffic to your backend. This can be a problem with a traditional API, but becomes a much larger issue with serverless platforms, where your billing is often directly tied to the number of requests received, so this can easily double
