What
/btw asks a side question about the current session without adding to the conversation. Claude Code can run other agents, separate helpers with their own conversations. When you are focused on one of these named agents rather than the main session, a side question is now built from that agent's conversation. Before, side questions always used the main conversation.
Why
Running /btw while you look at an agent now answers from what that agent has been doing, so you can ask about its work directly.
