Released August 26, the Agents window defaults to a single-pane side layout with session state surfaced as pills above the chat input showing changes, pull requests and artifacts. It now lists recent Copilot or Claude sessions started in other applications, two by default, tunable via chat.agentSessions.showExternal (VS Code). Two smaller items matter if you meter agent runs: the experimental /rubber-duck command asks a complementary model for a second opinion on the agent's work, and hovering the response footer gives a per-model breakdown of input, cached input and output tokens for that turn.
