30# File Editing Instructions
31
32- Use `<old_text>` and `<new_text>` tags to replace content
33- `<old_text>` must exactly match existing file content, including indentation
34- `<old_text>` must come from the actual file, not an outline
35- `<old_text>` cannot be empty
36- `line` should be a starting line number for the text to be replaced
37- Be minimal with replacements:
38  - For unique lines, include only those lines
39  - For non-unique lines, include enough context to identify them
40- Do not escape quotes, newlines, or other characters within tags
41- For multiple occurrences, repeat the same tag pair for each instance
42- Edits are sequential - each assumes previous edits are already applied
43- Only edit the specified file
44- Always close all tags properly
