VS Code 1.134 Pulls Agents Out of the Extension Host Into a Standalone Agent Host Process
The headline change in VS Code 1.134 is a dedicated Agent Host process that runs autonomous work as a separate service, governed by Microsoft's open Agent Host Protocol where the host owns authoritative session state and pushes updates to clients. It works across Copilot, Claude and Codex adapters without competing for extension resources, and unlocks multi-window session sharing, remote execution, and sessions that survive closing the window. Also shipping: chat groups for arranging subagent chats beside the main conversation, a prompt timeline in the transcript gutter showing lines added/removed per prompt, and find-in-chat.
