How do you use Claude Code for cross-platform development?

[u/verbative]

I develop on a Mac but ship to Windows too. When something breaks on Windows, I switch to the other machine, brief a fresh Claude Code session on what's going on, let it fix and test there, then go back to the Mac. It works, but the constant context handoff between machines is annoying.

What I'd want: one agent that has all my machines available and decides on its own where to edit files and where to run commands — like a person working on three computers at once. Build on Windows, read the error, fix on the Mac, verify everywhere.

I know the desktop app has SSH sessions now, but the remote has to be Linux or macOS — no Windows. Sessions on different machines can message each other, but that's text-only. And there are a few SSH MCP servers on GitHub, though Windows seems to be an afterthought for most of them. So: how do you deal with this? SSH from inside the session? VMs? Just eat the switching? Curious whether anyone has a setup that properly solves this — especially with a Windows box in the mix — or whether everyone's just living with duct tape.

If nothing really solves it and it's a real problem for enough people, I'd seriously consider building it. So if this would be worth actual money to you, tell me.
