This site focuses on "Broader Frontends" as a keyword, exploring a wide range of topics related to front-end and its surroundings, including web, XR, UI design, back-end, accessibility, art, music, and videos, based on where my interest takes me. https://yorihiroi-frontend.engineer Fri, 17 Jul 2026 09:08:01 GMT The first planned session of "Engawa AI x XR" was canceled because two typhoons were expected. This entry announces the rescheduled event. The second session will be held from 2:00 PM on August 1. After the cancellation, I gave it some thought and changed the event title slightly. https://yorihiroi-frontend.engineer/en/articles/NzDpPMK4NL0xqq4uHuAmmf/ https://yorihiroi-frontend.engineer/en/articles/NzDpPMK4NL0xqq4uHuAmmf/ Wed, 15 Jul 2026 12:34:53 GMT The longrumored Steam Machine suddenly went on sale on June 23. Personally, I thought it would launch around the same time as Steam Frame, meaning a little later, so it caught me completely off guard. But I had already decided before launch that I was going to buy it, so I went to the sales site on release day and purchased one. It arrived on June 30. I have spent some time setting it up, and now that a few things have become clear, I will write a review. https://yorihiroi-frontend.engineer/en/articles/EWbbkAGYEQoCZqWhdhhSXc/ https://yorihiroi-frontend.engineer/en/articles/EWbbkAGYEQoCZqWhdhhSXc/ Fri, 03 Jul 2026 09:29:41 GMT Sometimes I wonder whether Seiro MCP is still necessary now that even Xcode has MCP. But from the perspective of autonomous coding, I think Seiro MCP has the advantage of being lightweight and easy to handle. In that sense, there is still plenty of room to improve it as a product, which led to this release. This update adds fixes and features with the stance of making setup as easy as possible.

This time, I want to write about talks at "Engawa AI x XR." More than anything, I want to lower the barrier to giving a presentation. Through attending and speaking at various events so far, one thing I have felt is that there is often quite a gap between speakers and participants. https://yorihiroi-frontend.engineer/en/articles/D1aCxxsbPtyFaZQAeREhW/ https://yorihiroi-frontend.engineer/en/articles/D1aCxxsbPtyFaZQAeREhW/ Wed, 17 Jun 2026 13:12:44 GMT Over the weekend I needed to go to something like a general meeting, so on the train there and back I used Codex for Mobile to fix several bugs in my own project and add features with SpecKit. Here are some rough impressions. To start with the conclusion, it feels very usable. Codex on mobile https://yorihiroi-frontend.engineer/en/articles/3O635PLZ7WC3ACx2S64AO0/ https://yorihiroi-frontend.engineer/en/articles/3O635PLZ7WC3ACx2S64AO0/ Mon, 08 Jun 2026 21:56:12 GMT In the previous entry, I wrote an overview of "Engawa AI x XR," which will start in Motoyawata, and information about the first session. Starting a Study Community Called Engawa AI x XR Yorihiroi Frontend This time I will write about what I am vaguely thinking regarding the event structure. https://yorihiroi-frontend.engineer/en/articles/3ARoeQi6BaBe0QbWYoZOk1/ https://yorihiroi-frontend.engineer/en/articles/3ARoeQi6BaBe0QbWYoZOk1/ Fri, 05 Jun 2026 05:39:35 GMT I decided to try starting an AI x XR study community in my local Chiba Prefecture. I will write about the background and how this came about, including why I chose Motoyawata in Chiba as the base instead of Tokyo, which would be more advantageous for attracting participants. https://yorihiroi-frontend.engineer/en/articles/77hLSxhVnu1EPTPAmTUAgh/ https://yorihiroi-frontend.engineer/en/articles/77hLSxhVnu1EPTPAmTUAgh/ Tue, 02 Jun 2026 23:39:27 GMT Codex has expanded in many directions for customization, including custom prompts, MCP, and Skills. Among the newer features in this area are Marketplace and Plugin. This time, I will create a Marketplace locally and place a plugin in it. https://yorihiroi-frontend.engineer/en/articles/69mI2S6P8qhgMA52rwJOt5/ https://yorihiroi-frontend.engineer/en/articles/69mI2S6P8qhgMA52rwJOt5/ Sun, 24 May 2026 21:46:45 GMT I released v0.4.0 even though I had just released v0.3.1 a little while ago. This release does not add many features, but it marks a milestone because the default skill location on GitHub changed from skills/ to under .agents/skills. Release v0.4.0 karad/seiromcp https://yorihiroi-frontend.engineer/en/articles/6Sni8b8ENq855YHXoW8fr8/ https://yorihiroi-frontend.engineer/en/articles/6Sni8b8ENq855YHXoW8fr8/ Fri, 17 Apr 2026 06:37:43 GMT Some people may have seen this in the news a little while ago, but apparently the driver released by Tinygrad lets you connect an external eGPU to a Mac and use it for LLMs. https://yorihiroi-frontend.engineer/en/articles/16pBAiDZ4OdOaN9ETRf02z/ https://yorihiroi-frontend.engineer/en/articles/16pBAiDZ4OdOaN9ETRf02z/ Fri, 10 Apr 2026 12:24:19 GMT
