AIコーディング前提の開発プロセスを仕組み化 はじめまして。松尾研究所の中川です。 AIコーディングを前提に、提案から開発・運用までを一気通貫で進めるスタイルは増えつつあります。弊社のプロジェクトでも、AIコーディングは単なる「補助」ではなく、開発プロセスの中核として扱われる場面も多くなってきました。 私も小規模体制で開発速度と品質を両立するために、Claude Codeの運用における 並列化・プロンプト運用・レビュー自動ループ・ナレッジ一元化・インストラクション（Skills） の5点を“仕組み”として作っています。 この記事では、Claude Code中心のAIコーディング手法をまとめます。 開発対象 Claude Codeの実務運用で開発したWebアプリ構成です。 フロントエンド： React + Vite + TypeScript バックエンド： FastAPI 非同期処理ワーカー
Claude CodeとPlaywright MCPで実現する対話型UI自動テスト構築 | DevelopersIO
はじめに UIテストを書くとき、 「セレクタを探す → 失敗する → ブラウザを見直す」 という往復に時間を取られていませんか？ 本記事では、Claude Code と Playwright MCP を組み合わせて、 実際のブラウザ操作を確認しながら対話的にUIテストを構築する方法を紹介します。 テストコードをあとから書くのではなく、 確認作業そのものをテスト生成につなげる のがこの方法の良いところです。 本記事は、Claude CodeとPlaywrightを利用したことがある方向けに書いています。 各サービスについて詳しく知りたい方は、こちらをご覧ください。 Claude CodeとPlaywrightの参考ブログ 動画で動きを紹介 モバイル表示時のハンバーガーメニューのテストを対話的に作成している例です。 こんなことができます。 生成したテストコードの詳細 この記事で作成したテストコ
今年も GitHub トレンドから 2022 年の JavaScript/TypeScript を振り返ります。去年の記事はこちらです。 — GitHub のトレンドで振り返る 2021 年の JavaScript | WEB EGG 集計方法 本記事の集計期間は 2022/01/01〜2022/12/07、対象言語は JavaScript および TypeScript です。 なお GitHub がそのリポジトリをなんの言語と見なしてトレンドに掲載したかをもとに集計対象を決定していることにご留意ください。 別言語で書かれた Rust 製の JS 向けのツールや CSS フレームワークなどは基本的に対象外となります。 集計に利用したデータですが、GitHub は過去のトレンドを閲覧する方法を提供していないため、独自の仕組みで GitHub トレンドのアーカイブを生成しそのデータを利用しまし

I use Claude Code. A lot. As a hobbyist, I run it in a VM several times a week on side projects, often with --dangerously-skip-permissions to vibe code whatever idea is on my mind. Professionally, part of my team builds the AI-IDE rules and tooling for our engineering team that consumes several billion tokens per month just for codegen. The CLI agent space is getting crowded and between Claude Cod
Playwright for Python: ブラウザ操作を自動化しよう！ - kakakakakku blog
ブラウザ操作を自動化して，E2E (End to End) テストやスクレイピングをするときに使えるライブラリ Playwright を試す．Playwright の特徴としてまず「クロスブラウザ」があり，Chromium / Firefox / WebKit をサポートしている．また「複数言語」という特徴もあり，Node.js / Python / Java / .NET をサポートしている．今回は Playwright for Python を前提にする． playwright.dev Playwright の前に 過去の経験を思い出すと，Capybara + PhantomJS で E2E テストを実装していた（2015-2016年頃でなつかしい！）．また最近だと Puppeteer や Amazon CloudWatch Synthetics を使う機会も増えている．しかし，個人的
Today, we are excited to announce the launch of .NET 10, the most productive, modern, secure, intelligent, and performant release of .NET yet. It’s the result of another year of effort from thousands of developers around the world.

2025: The year in LLMs
31st December 2025 This is the third in my annual series reviewing everything that happened in the LLM space over the past 12 months. For previous years see Stuff we figured out about AI in 2023 and Things we learned about LLMs in 2024. It’s been a year filled with a lot of different trends. The year of “reasoning” The year of agents The year of coding agents and Claude Code The year of LLMs on th

Published Sep 29, 2025 The Claude Agent SDK is a collection of tools that helps developers build powerful agents on top of Claude Code. In this article, we walk through how to get started and share our best practices. Last year, we shared lessons in building effective agents alongside our customers. Since then, we've released Claude Code, an agentic coding solution that we originally built to supp

Running OCR against PDFs and images directly in your browser
30th March 2024 I attended the Story Discovery At Scale data journalism conference at Stanford this week. One of the perennial hot topics at any journalism conference concerns data extraction: how can we best get data out of PDFs and images? I’ve been having some very promising results with Gemini Pro 1.5, Claude 3 and GPT-4 Vision recently—I’ll write more about that soon. But those tools are stil
10th December 2025 I’ve started using the term HTML tools to refer to HTML applications that I’ve been building which combine HTML, JavaScript, and CSS in a single file and use them to provide useful functionality. I have built over 150 of these in the past two years, almost all of them written by LLMs. This article presents a collection of useful patterns I’ve discovered along the way. First, som
