Greptile Overview

Greptile Summary

Added a new filterOutputForDisplay method that filters out childTraceSpans from workflow block output before sending to the UI via onBlockComplete callback. The childTraceSpans data is still preserved in logs through filterOutputForLog, ensuring trace data remains available for debugging while hiding the raw JSON from end-user UI.

Key Changes:

• Introduced filterOutputForDisplay method that wraps filterOutputForLog and additionally removes childTraceSpans for workflow block types
• Updated both success and error paths in execute method to use filterOutputForDisplay instead of filterOutputForLog when calling onBlockComplete
• Imported isWorkflowBlockType helper function to identify workflow blocks
• Preserved existing behavior for block logs (still includes childTraceSpans in log output)

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is well-designed and surgically implements the stated goal. It introduces a clean separation between log output (which retains all data) and display output (which hides internal trace spans). The implementation correctly handles both success and error paths, uses proper TypeScript destructuring, and follows existing patterns in the codebase. No logical issues, edge cases, or security concerns identified.
• No files require special attention
