Awesome Dan. And you can create your own agent characters. Here is Marvin who monitors my VSCode Agents running on another host via @TylerLeonhardt ‘s AHPX library

I've pretty much been an opus boi since 4.5 dropped but recently..... I've been using 5.6 sol... intentionally. It's actually really great. I like that we can offer both multi-model & multi-harness experiences in @code ... I never get FOMO

My new setup I’m trying out: * AH1 * AH2 * AH3 * AH4 4 beefy cloud dev boxes (devbox.microsoft.com) All can control dev builds of @code and send me artifacts All running Agent Hosts that I connect to from my local @code’s Agents window - which I also use for quick tasks.

This feature was entirely built using this setup, and honestly I felt really productive. Being able to close my laptop and know that my agent hosts are still running is a huge time saver.

🎨 Added "Set Background" to @code's Agent Window so you can make it yours. It comes with a built-in Codicons background. You can also change the layout so, for example, I've put the Insiders logo in the bottom right. "food" is from: transparenttextures.com lmk what you think!

man agents really do love adding private properties to classes. this shit compounds and then you have all these privates depending on each other and it all quickly becomes a mess. I’ve also seen so much passing in closures that mask cyclical dependencies. How do you deal?

agent sessions just got way more portable 🚀 agent host runs copilot, claude, and codex in dedicated processes, lets sessions move across windows and clients, and powers copilot with the Copilot SDK, aligning with copilot cli, app, and other copilot platforms! now 100% rolled out, set your session target to "Copilot" to try it out. more architecture docs here: code.visualstudio.com/update…
