EDIT_FILE_TOOL_DESCRIPTION = 'Performs exact string replacements in files.\n\nUsage:\n- You must read the file before editing; this tool errors otherwise.\n- Preserve the exact indentation from the read output, and never include line-number prefixes in old_string or new_string.\n- Prefer editing an existing file over creating a new one.\n- Only use emojis if the user explicitly requests it.'
