On February 18, 2026, Seiro MCP finally reached version 0.1.0. At first I had so little confidence that I started from 0.0.1. The major topics this time are Skills support and added diagnostic functionality around SDKs. I am a heavy user of Seiro MCP to the point that I use it every day, so I decided that if I am using it this much myself, it is fair to call it 0.1.0. Incidentally, I also added a logo.
Seiro MCP, which I released at the end of last year to support development for visionOS,
may look like it has not moved much since release, but I actually use it almost every day. Rather than saying I use it, the AI uses it automatically, so when I am developing for visionOS, it is heavily used to check whether the implementation can be built every time, alongside the implementation itself. That Seiro MCP has had about two updates released this month.
Notion has helped me a great deal. After using it for nearly five years, it had become like air, naturally sitting at the center of my life to the point that opening Notion was the first thing I did after waking up. So why did I decide to migrate? A major reason was the change happening in my own environment.

I did not write a best-buys entry in 2024, but if I had, it would probably have been the Vision Pro. That personal interest continued, and in 2025 I bought many accessories and related items around XR. So here are my top five best buys of 2025.
