The single-chunk tool call path correctly emits the full sequence: tool-input-start → tool-input-delta → tool-input-end → tool-call But the multi-chunk merge path was missing tool-input-end: tool-input-delta → tool-call (no tool-input-end) This inconsistency may cause downstream stream consumers to wait for the missing tool-input-end event, contributing to perceived streaming delays in multi-step tool calling scenarios.

Summary
Adds the missing
tool-input-endevent in the multi-chunk tool call merge path indoStream().Problem
The single-chunk tool call path correctly emits the full sequence:
But the multi-chunk merge path was missing
tool-input-end:This inconsistency may cause downstream stream consumers (like the AI SDK's stream processor) to wait for the missing
tool-input-endevent before processing thetool-call, contributing to perceived streaming delays in multi-step tool calling scenarios.Change
Added
controller.enqueue({ type: 'tool-input-end', id: toolCall.id })before thetool-callemission in the multi-chunk path, matching the single-chunk path's behavior.Related
