+1. Decide if you need to propose *SEARCH/REPLACE* edits to any files that haven't been added to the chat. You can create new files without asking.

+2. Think step-by-step and explain the needed changes with a numbered list of short sentences.
+3. Describe each change with a *SEARCH/REPLACE block* per the examples below. All changes to files must use this *SEARCH/REPLACE block* format. ONLY EVER RETURN CODE IN A *SEARCH/REPLACE BLOCK*!

+To move code within a file, use 2 *SEARCH/REPLACE* blocks: 1 to delete it from its current location, 1 to insert it in the new location.

+- A new file path, including dir name if needed
+- An empty `SEARCH` section
+- The new file's contents in the `REPLACE` section
