How to stop AI from changing too much

Simple explanation

When you give AI a task, it often adds improvements you did not ask for — it refactors code, renames variables, reorganizes files, adds new features. Each extra change is a new thing that could break your app. The model is not being reckless. It is trying to help. But for non-developers, more changes means more risk.

What to do

Add a scope constraint at the end of every prompt. This one sentence significantly reduces unwanted changes. Pair it with a narrow, specific task description and the results will be much more predictable.

Copy-paste prompt

[Your specific task here.] Important: please change only what I have asked you to change. Do not refactor, rename, reorganize, or improve anything I have not mentioned. Keep all other code exactly as it is.

Course note

The course uses a prompt template system that includes scope constraints by default. Once you use this consistently for a week, it becomes automatic.

Key takeaway

End every prompt with a scope constraint. Make it a habit.
