EditReplace exact strings in files with new text, preserving indentation. Requires prior file read for context.
Instructions
Performs exact string replacements in files.
Usage:
You must use your
Readtool at least once in the conversation before editing. This tool will error if you attempt an edit without reading the file.When editing text from Read tool output, ensure you preserve the exact indentation (tabs/spaces) as it appears AFTER the line number prefix. The line number prefix format is: line number + tab. Everything after that is the actual file content to match. Never include any part of the line number prefix in the old_string or new_string.
ALWAYS prefer editing existing files in the codebase. NEVER write new files unless explicitly required.
Only use emojis if the user explicitly requests it. Avoid adding emojis to files unless asked.
The edit will FAIL if
old_stringis not unique in the file. Either provide a larger string with more surrounding context to make it unique or usereplace_allto change every instance ofold_string.Use
replace_allfor replacing and renaming strings across the file. This parameter is useful if you want to rename a variable for instance.
