⚠️ New File Creation: Search for Existing Code First!

You're creating a new source file. Before proceeding, you MUST search for existing similar code.

Required checks before creating this file:

1. Search for similar names:

   Use Grep or find_symbol to search for:
   - Similar class names
   - Similar function names
   - Similar module names
   

2. Check neighboring files:

   Use Glob or list_dir to examine:
   - Files in the same directory
   - Files in sibling directories
   - Related modules that might already have this functionality
   

3. Search for similar patterns:

   Use search_for_pattern to find:
   - Similar functionality that could be reused
   - Base classes that could be extended
   - Utilities that already solve this problem
   

Why this matters:

• Code duplication creates maintenance burden
• Existing code may already solve your problem
• Reusing code ensures consistency
• This project forbids creating new modules without justification (see CLAUDE.md)

If similar code exists:

• Extend the existing module instead
• Add to an existing file if appropriate
• Import and reuse existing utilities

If you've already searched: Proceed with file creation. This is just a reminder.

Project reference: See CLAUDE.md section on "Module Creation" - creating new files/modules is forbidden without valid justification.
