3737Fine-grained tool streaming delivers a tool’s input to your client as Claude generates it, without server-side buffering or JSON validation. Skipping the buffering step reduces the time to the first fragment of a large parameter, such as a document or a block of code, and the fragments arrive through the same [Streaming messages](https://platform.claude.com/docs/en/build-with-claude/streaming) events as standard tool use.
