What
Claude Code has an instruction that tells the model to end its turn, with no acknowledgment, after it has called a particular tool to return structured output. That instruction previously filled in the wrong tool name. It now names the correct tool, and a further block of text is added at the end.
Why
This is a correction to wording the model sees. It may make the model more reliable about stopping once its structured answer has been sent.
