Greptile Summary

Fixes streaming chat to display all selected workflow outputs, not just content. The hook now accumulates block logs during execution and passes them in the final event, allowing the chat component to extract and display non-content outputs like model, tokens, and toolCalls. This ensures all user-selected outputs appear in the chat response.

Confidence Score: 3/5

• Generally safe to merge with minor optimization concerns
• The fix correctly addresses the issue by accumulating block logs and extracting selected outputs from the final event. The logic is sound and properly handles edge cases (skipping content path, checking for undefined values). However, the accumulation of block logs without size limits in long-running workflows could lead to memory issues. The dependency array update is correct, preventing stale closure issues.
• apps/sim/app/workspace/[workspaceId]/w/[workflowId]/hooks/use-workflow-execution.ts for potential memory optimization

Greptile Overview

Greptile Summary

Enhanced chat streaming to extract and display all selected output fields (like model, tokens, toolCalls) from execution logs, not just the content field.

Key Changes:

• Added logic in processStreamingResponse to process the final execution result and extract non-content selected outputs from block logs
• Modified useWorkflowExecution to accumulate BlockLog entries during execution so they're available in the final event
• Updated dependency array in processStreamingResponse to include selectedOutputs and activeWorkflowId

Confidence Score: 4/5

• This PR is safe to merge with minimal risk - focused bug fix with proper error handling
• The changes are well-contained and address a specific bug where non-content output selections weren't being displayed in chat. The implementation follows existing patterns, includes proper guards, and correctly filters out the content path to avoid duplication. Dependencies are properly declared in useCallback.
• No files require special attention
