Duplicate Code Removal

Find repeated code patterns and extract into common functions.

Prompt

Find and remove duplicates in this code:
1. Identify places with repeated logic
2. Extract into common utility functions
3. Use generics/type parameters
4. Show code after applying DRY
5. Write tests for extracted functions

Use Case

Use this when similar validation, data transformation, or API call code is copy-pasted across multiple files and fixing one means updating all the rest. Paste the repeated code blocks to get them extracted into common utility functions with tests included.
