こんにちは！逆瀬川 (@gyakuse) です！ 今日は「AGENTS.mdを自動で育てたい」という話をしていきたいと思います。作ったものはagents-md-generatorとして公開しています。 CLAUDE.mdを毎回考えるのがつらい Coding Agentを日常的に使っていると、新しいリポジトリを作るたびに頭を悩ませるものがあります。CLAUDE.md（あるいはAGENTS.md）です。 何を書くか毎回考えるのがまずつらい。プロジェクトのビルドコマンドは？テストの走らせ方は？コード規約は？まだ何もコードがない段階でこれを考えるのは不毛です。かといって空のまま放置すると、Coding Agentが手探りで動くことになって効率が悪い。 もっと根本的な問題もあります。CLAUDE.mdは書いた瞬間から劣化し始めます。プロジェクトが進めばコマンドは変わるし、アーキテクチャも変わる。でも
The way content and businesses are discovered online is changing rapidly. In the past, traffic originated from traditional search engines, and SEO determined who got found first. Now the traffic is increasingly coming from AI crawlers and agents that demand structured data within the often-unstructured Web that was built for humans. As a business, to continue to stay ahead, now is the time to cons

Introduction Welcome to The CSS Selection 2026! In this article we’re having a look at how CSS is used at scale on over 100,000 websites. We’ll look at what things are common on most websites and discover interesting outliers. This is the first edition of what I hope to be many, so this is meant as a baseline for future editions, setting up the first numbers to compare with in coming years. This a
Year after year, React bucks the trend of the ever-changing web development landscape by subbornly refusing to become obsolete, and evolving with the times–or sometimes even ahead of them. And with generative AI's reliance on existing codebases in order to spew out new code, could React become even more entrenched and effectively become the first “forever framework”? We won't know the answer to th

This change is intended to reduce confusion, improve reliability, and encourage use of the GitHub platform’s built-in tools for working with pull reque
In my first job as a software engineer the project I was working on grew out of control. As often happens, use cases were added without proper refactoring and with more users we were drowning in support tickets and nothing seemed to work. It was clear we needed to push for quality so we started adding unit tests. The tech lead at the time mandated high test coverage. But here's the reality: writin
