Greptile Overview

Greptile Summary

This PR adds comprehensive folder duplication functionality to match existing workflow duplication capabilities. The implementation includes recursive folder structure duplication and workflow duplication within those folders.

Key Changes:

• Created reusable duplicateWorkflow helper in lib/workflows/duplicate.ts that handles workflows, blocks, edges, subflows, and variables with proper ID remapping
• Added /api/folders/[id]/duplicate endpoint that duplicates folder hierarchies recursively and then duplicates all workflows within
• Added /api/workflows/[id]/duplicate endpoint that uses the shared helper
• Created useDuplicateFolder and useDuplicateWorkflow hooks following the same pattern as delete hooks
• Added useDeleteFolder hook to extract deletion logic from component
• Updated ContextMenu component to support optional duplicate action
• Integrated duplicate functionality into both folder-item and workflow-item components
• Added duplicateFolder method to folder store that refreshes state after duplication

Implementation Quality:

• Follows consistent patterns with existing delete hooks
• Proper transaction handling for folder structure duplication
• Comprehensive permission checks
• Good error handling and logging throughout
• Supports both single and bulk operations
• Properly clears selection after operations
• Navigates to duplicated workflow (single workflow duplication only)

Confidence Score: 5/5

• This PR is safe to merge - well-structured implementation following established patterns with proper error handling
• The implementation follows consistent patterns throughout the codebase, includes comprehensive permission checks, proper transaction handling, and thorough error handling. The shared helper function promotes code reuse, and the hooks pattern matches existing delete functionality. All edge cases are handled appropriately including ID remapping, parent relationships, and selection clearing.
• No files require special attention
