Greptile Overview

Summary

This PR fixes a bug where subblock options weren't being sent to the copilot by significantly expanding the metadata extraction capabilities. The changes include:

• Expanded interface: Added 25+ new optional fields to CopilotSubblockMetadata covering dropdown options, numeric constraints, text properties, OAuth settings, file handling, and more
• Enhanced processing: Replaced simplifySubBlock with processSubBlock that comprehensively extracts all subblock properties instead of just basic ones
• Options resolution: Added resolveSubblockOptions function that properly handles function-based options and detects icon presence
• Data cleanup: Added pruneNullishDeep utility to remove null/undefined values from final output

The fix ensures the copilot receives complete subblock metadata including the previously missing options field, enabling proper UI rendering and functionality.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• Score reflects well-structured code expansion that addresses a specific bug with comprehensive error handling, proper TypeScript types, and no breaking changes
• No files require special attention
