VS Code: Sessions Drag-Drop, Agent Warm Starts, and Harness Policy
Sessions management and agent-host reliability dominated the last 24 hours, with drag-and-drop ordering, working-set Keep and Undo, and fixes for wasted pre-warmed sessions and slow first turns. Enterprise Copilot harness policy also flipped twice in one day.

First, sessions management. Drag-and-drop for chats and sessions landed in the sessions list in PR 342624, followed closely by a server tool that lets an agent move sessions itself in PR 342694, and a fix in PR 342849 that makes the sessions provider the sole owner of nested chat order. New session panes can now…

PR 342680 fixed pre-warmed sessions that were almost never claimed — logs showed 39 warm starts and zero claims — due to disposal races and orphaned launches, with follow-ups in PR 342712. PR 342634 tackles slow first Copilot turns taking minutes by passing sandbox…
