Jujutsu (jj) flipped my mental model: the working copy is a commit.
In Git, commits end work. In jj, they begin it.

The Making of a Stylish Dog-Centered Lifestyle Media using Giselle Building a dog-centered lifestyle media site with vibe coding and Giselle. AI doesn't replace thinking—it preserves the conditions where human judgment stays effective.

Built a stylish dog lifestyle media site 🐶✨
AI didn't decide anything—worldview, tone, editorial judgment stayed with me.
Giselle wasn't a generator. It was infrastructure for judgment. 🧠🔧

Managing Coding Agents: Zed + Cursor A practical workflow for managing coding agents: keep Zed as your home base, run agents in Cursor, and use git worktree plus Agent/Plan mode for fast, isolated iteration.

Zed + Cursor + git worktree = Our AI coding flow ⚡️

Isolated worktree → agents in Cursor → review & ship in Zed. Fast 60-80% beats "perfect but slow" 🚀

What Giselle is not Setting expectations and clearing up misconceptions about Giselle. Understanding what Giselle is not helps clarify what it actually is and who it's for.

Giselle isn’t a #ChatGPT replacement, a “no-code automation” shortcut, or a magic app generator. 🚫🤖

It’s built to keep thinking visible: branches, decisions, and state—so workflows stay understandable, reviewable, and shareable. ✍️🧩

Node-Based Interfaces for People Who Don't Think in Flowcharts — Building Giselle How designers translate UI requirements and communicate design intent. Exploring the process of interpreting UI specifications and translating them from a designer's perspective.

Turns out, the canvas doesn't tell you what to think. It just shows you where you haven't thought yet. ✨

We designed Giselle’s UI using Giselle itself. 🎨

Instead of locking specs upfront, we “stacked decisions” through working prototypes—while querying our own codebase inside Giselle to keep design grounded in what’s actually buildable. 🛠️🤖

伊藤忠テクノ、システム開発の要件定義AI　上流工程を短縮 - 日本経済新聞 伊藤忠テクノソリューションズ（CTC）は24日からシステム開発の要件定義をAI（人工知能）が生成するサービスを始めた。システム構築時に顧客企業が必要とする機能や仕様を整理する工程をAIが担うことで開発工程を短縮できる。要件定義AI「Acsim（アクシム）」はソフトウエア開発のROUTE06（ルートシックス、東京・千代田）が開発した。

CTC様より、弊社が開発した要件定義AI「Acsim」のサービス提供が開始されました！
要件定義書の作成を1ヶ月以上→約1時間に短縮。システム開発の上流工程にAIを活用することで、開発全体のスピードとコストに貢献できると考えています。
