Devin, Coding Agent (Github Copilot), Codex (OpenAI) やJules (Google)のような、バックグランド動作するコーディングエージェントが続々と発表されて、ついに先日のAnthropicのカンファレンスでClaude Codeでも同様のことが行えるようになりました！ Claude CodeのDevin型コーディングエージェントはGithubワークフロー上で動作するのですが、なんと実装のコードがなんと公開されているではありませんか！！ プロンプトやGithubのMCP設定等の実装も垣間見ることが出来ます！ AIエージェントを開発している身からすると常時稼働型エージェントを作りたいと考えており、バックグラウンド型のコーディングエージェントの動作はどうしても深ぼらねばと思っていた矢先に撒き餌が...！ それだけでなく、プロンプト設計自体の完

jQuery 4.0.0 has been in the works for a long time, but it is now ready for a beta release! There’s a lot to cover, and the team is excited to see it released. We’ve got bug fixes, performance improvements, and some breaking changes. We removed support for IE<11 after all! Still, we expect disruption to be minimal. Many of the breaking changes are ones the team has wanted to make for years, but co

Devinにお願いしてソースコードからドキュメントを生成してもらえると面白そうなので実験してみた。Devin Wiki や Deep Wiki もあるんだけど、それとは別に自分で指示を出してコントロールできるのもいいかなという気持ち。 どうせ作るなら自分がドキュメントを読みたいやつがいいなぁと思って、ecspresso が好きだから、ecspressoのソースコードからドキュメントを生成してみることにした。 軽い気持ちでやってみたら、思ってたより苦戦した。すごくいい感じにできたわけじゃないので「この記事をめちゃ信じる！」んじゃなくて「へー、ちょっと参考にしとこっか」くらいが良いと思う。 勢いで書かないと書き終わらなさそうだったので、勢いでざーっと書いた。ので長い。 できあがったもの できあがったものを最初に書いておく。わりと気に入ってる。ただ、生成するたびに色々変わるので、雰囲気で参照する

This post is part of a collection on UUIDs. What is IDOR? Indirect Object Reference (IDOR) occurs when a resource can be accessed directly by its ID even when the user does not have proper authorization to access it. IDOR is a common mistake when using a separate service for storing files, such as a publicly readable Amazon S3 bucket. The web application may perform access control checks correctly

LLMによるコード補完の登場 (2021年) GitHub Copilotの登場 我々がよく知るLLMによる支援はまず GitHub Copilot から始まりました。これはGPT-3 (OpenAI Codex, 現在のCodexと名前が同じで本当にややこしい) をベースとしたコード補完システムで、タイピングをしていると自動的にその行の続きを予測してくれるものです autocompleteとの違い それ以前にもIntelliSenseのようなautocompleteがありましたし、より進歩したn-gramなどを用いたものはありましたが、LLMをベースとしたものはTabnine (Tabnineは初期はn-gramモデル) やCopilotからとなります チャットベースのコードアシストの時代 (2022-2023年) ChatGPTの登場 ChatGPT以降、チャットによる対話形式でコード

It is wild to think that it has been only a handful of weeks. Claude Code has considerably changed my relationship to writing and maintaining code at scale. I still write code at the same level of quality, but I feel like I have a new freedom of expression which is hard to fully articulate. Claude Code has decoupled myself from writing every line of code, I still consider myself fully responsible
