Mon, 23 Mar 2026 10:01:56 +0900

I sincerely apologize for the poor delivery. I promise to make the most of this reflection (if there is a next time…) and take the stage fully prepared and in good condition.
I learned a great deal from speaking with so many people. Thank you very much.

On Releasing Setsuna, a Cross-Device Text Sharing Service

Wed, 31 Dec 2025 23:11:04 +0900

As the title says, I released Setsuna, a cross-device text sharing service, on 12/28.

(The sample demo has been taken down.)

デバイス間テキスト共有アプリSetsunaをリリースしました。https://t.co/FNbVd8ohHO https://t.co/8VPNjyX0K7

昔自分用につくって公開していたOSSを、Claude Codeに全面バックアップしてもらってリバイバルしたものです。…
— びーぐる / Beagle Works (@beagle_dog_inu) December 28, 2025

(Since it was abbreviated, I’ll write it out here)
“This is a revival of an OSS I made for personal use a while back, with full backing from Claude Code. There are plenty of similar tools out there now and it’s nothing special, but I wanted to rebuild it once with modern tech as a learning exercise, so I released it.”

Reading 'Introduction to AI-Driven Development with Claude Code'

Wed, 31 Dec 2025 20:17:39 +0900

I read “Introduction to AI-Driven Development with Claude Code” (Claude Code によるAI駆動開発入門).

I shared some of my thoughts on X.

池袋に行ったのでジュンク堂でClaude CodeによるAI駆動開発入門、買いました。これはもういい意味で教科書ですね。使ったことないひとは体系的に学べる、使ったことあるひとはパラパラめくるだけで何かしら発見があるようなイメージ。 pic.twitter.com/fUPNrjwPQz
— びーぐる / Beagle Works (@beagle_dog_inu) December 10, 2025

既にほとんど知っている事柄に関して、他の人の異なるアプローチや考え方にふれる、記事や書籍を読む、ってのは本当によいことで。
新たな知識は増えないけど、代わりに新たなインスピレーションや気付きは発生するのでとても大事にしている。当然理解も深まり言語化もうまくなる。
— びーぐる / Beagle Works (@beagle_dog_inu) December 20, 2025

I also spoke about how great this book is to several people at the Claude Code Meetup Tokyo I recently attended.

Claude Code Meetup Tokyo · Luma

https://luma.com/ioed4ksj?tk=U0Wvfo

Beyond covering the basics of Claude Code in a textbook-like manner, what makes this book really stand out is that you can see what the author, Hirakawa-san, instructs Claude Code to do for a given requirement, and understand “what they’re thinking.” Even if you already know Claude Code well, reading from this perspective will teach you a lot. I certainly learned a great deal.

The Site

Tue, 25 Nov 2025 00:00:00 +0000

The Site…?

Yes.

That’s the name of the site.
There’s probably no deep meaning behind it. Maybe.

How Was It Built?

Hugo + PaperMod
Hugo is great because it’s easy to customize. And if you get stuck, you can just ask an AI.

Main Customizations (Notes)

Hatena Bookmark share button
Zenn-style author block (below articles)
Author icon

I think that’s about it…?
