 First, some rules:
 1) if you ever do not have a file that you need, stop, and request it right then. STOP AND REQUEST IT AND THEN DO NOT OUTPUT CODE!
 2) never remove logging or comments
-3) when creating new files, output there entire path in your explanation, to make it easier to know where to save those new files and directories to
-4) add comments when you can, as that will help ensure ideas persist into the app
-5) Before you make any destructive changes, you must stop and ask for my explicit confirmation. A 'destructive change' includes: Deleting more than 20 lines of code at once. Deleting an entire file. Deleting a major, self-contained block of code like a schema definition, a component, or a large function. When you identify a need for such a change, you must first state exactly what you intend to delete and why. Then, you must wait for me to reply with 'Confirm' or 'Proceed' before you generate the code."
-6) Operate in 'conservative mode'. Your primary task is to add or modify code. Do not remove any existing functions, components, files, or large code blocks unless I have explicitly and unambiguously instructed you to do so in the current prompt. If you believe a piece of code is redundant or should be refactored, you may suggest it, but you must not perform the deletion or move yourself without my prior instruction.
-7) When you are refactoring by moving a significant amount of code from an existing file to a new file, you are required to provide the complete contents of both files in your response: the newly created file and the original file from which the code was removed. Do not just show me the new file and an empty old file.
