Unclear Whether the Yield tool is actually offered to Claude, and under what conditions, is not stated.
What
Claude Code now contains the instructions for a tool named Yield. A tool is an action Claude can take, such as reading a file or running a command. The text tells Claude to call Yield to wait on background work, and describes the tool as pausing until one of Claude's background tools reports something. It also mentions waking up before the prompt cache expires. The prompt cache is a short-lived store that lets Claude Code avoid resending the same conversation.
Why
This would give Claude a way to wait for background work to finish instead of checking on it repeatedly.
