Unclear It is not clear what condition decides whether this mid-turn path is used.

What

When another program drives Claude Code through stream-json mode, the streaming JSON input and output used by the SDK, some slash commands can now run while a turn is under way. A turn is one round of Claude working on a request. This applies to commands that support showing their result inline. Claude Code also now keeps track of commands that were declined and not answered.

Why

Programs built on the SDK may get some slash commands answered straight away instead of waiting for the current reply to end.
