Finally got access to Jev, so I was able to test jev-dotnet against the live API. Happy to confirm it works with the real service too 🎉 github.com/kkdev92/jev-do… #Jev #dotnet #csharp #OSS
Cloud sessions are officially available and out of research preview! They let you keep Claude Code working, even when your laptop is closed. Existing subscribers get a one-time credit to try them: $100 on Pro, $250 on Max.
Try these in your first Opus 5.5 session: → Hand over a whole task. Define "done" and when to check in. → Drop "think carefully". It always thinks first. → After a long run, check what it needs to go further. Our playbook: claude.dev/blog/getting-t…
The main thing I wanted to share in my LT was Microsoft Learn MCP Server. If you’re building with C#/.NET, make sure to add it to your MCP setup.
My C# Kaigi 2026 LT slides are now on Speaker Deck! I’ve been using C#/.NET for about 10 years, so I took a look back at how .NET and its ecosystem have evolved — and why I’ve come to like C#/.NET even more in the AI era. speakerdeck.com/kkdev92/net-ga… #csharpkaigi #dotnet #csharp
Had a great time at C# Kaigi 2026! Really enjoyed giving my LT and chatting with so many C#/.NET developers. Such a fun and inspiring event. Thanks everyone! #csharpkaigi

Feels like it’s about time for another coding retreat at an onsen ryokan.
Astra was probably our biggest competitive advantage while it wasn’t generally available. Since we’ve had it our productivity jumped so much that we shifted some of our plans 6 months ahead and will ship them at DevDay instead of mid next year.
We are also excited!
Excited to see early customers already using Astra on Azure! azure.microsoft.com/en-us/blog/gpt…
This is GPT-6 Astra. Anything you can do on a computer, Astra can do for you. Fast.
Fable 5.1 is now live in Claude Code and the Claude Platform. It's priced the same as Fable 5, with 75% cheaper API cache reads. It gets a lot further into a long task before it needs your input, is better at telling you when it's stuck, and its writing style is more natural.
We’re introducing Claude Fable 5.1 and Claude Mythos 5.1. They're the world’s most advanced models for coding and knowledge work.
With Fable 5.1 out today, we've also reset 5-hour and weekly limits for all users.
There’s something indescribably cute about that expression. It’s so soothing. #ｽﾀｯｸﾁｬﾝ #Stackchan
