The prompt that makes Cursor add a feature cleanly instead of rewriting half your app.
I'm working in Cursor on an existing app. I want you to add this feature: [DESCRIBE THE FEATURE] Before writing any code: 1) Look at the existing code structure and tell me which files you'll touch and why. 2) Ask me anything you need to avoid guessing. 3) Propose the smallest change that works — no refactoring unrelated code. Then implement it step by step, explaining each change in plain English as you go. Don't delete or rewrite anything that isn't directly part of this feature. After, give me a short checklist of what to test to confirm it works.
