 - 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.
 - Use \`replace_all\` for replacing and renaming strings across the file. This parameter is useful if you want to rename a variable, for instance.
 
 WARNINGS:
 - When not using \`replace_all\`, the edit will FAIL if \`old_string\` is not unique in the file. Either provide a larger string with more surrounding context to make it unique or use \`replace_all\` to change every instance of \`old_string\`.
