claude-code - 💡(How to fix) Fix [BUG] Intermediate text between tool calls is not streamed to the user [1 participants]

TL;DR

Implementing a mechanism to flush or yield control back to the streaming process after each text segment is produced, regardless of tool calls, is likely necessary to achieve the desired real-time streaming behavior.

Guidance

• Investigate the current buffering or caching mechanisms in place for text segments between tool calls to understand why they are not being streamed immediately.
• Consider introducing a yield or flush operation after each text segment is generated to ensure it is sent to the user without waiting for subsequent tool calls to complete.
• Review the model's response generation logic to identify any implicit assumptions about tool call completion before streaming text, and adjust accordingly to prioritize real-time updates.
• Test the implementation with various tool call patterns (e.g., text → tool → text → tool → text) to ensure intermediate text segments are streamed as expected.

Example

No specific code example can be provided without more details on the implementation, but the concept would involve ensuring that after each text segment is generated, there's an explicit step to send or yield that segment to the user, rather than buffering it until all tool calls are complete.

Notes

The exact solution may depend on the specifics of the model's response generation and streaming implementation, which are not fully detailed in the issue. Additionally, ensuring real-time streaming may require balancing between immediate updates and potential performance considerations.

Recommendation

Apply a workaround by introducing a yield or flush mechanism after each text segment, as this directly addresses the observed behavior of buffering until tool calls complete, and allows for incremental progress updates to be streamed to the user.
