Lovable Keeps Changing Things I Didn't Ask It To
Quick Answer
Vague prompts give Lovable too much freedom. It interprets broad requests broadly and may touch files beyond what you intended. Start with "Use scope limiters in every prompt" before making broader code changes.
You're in the right place if...
- !Asked to change button color, whole layout changed
- !Lovable rewrites components you didn't mention
- !Previous working features break after prompts
Why this happens
Vague prompts give Lovable too much freedom. It interprets broad requests broadly and may touch files beyond what you intended.
Fix
Use scope limiters in every prompt
Always prefix your prompts with explicit boundaries. This prevents Lovable from touching anything you didn't mention.
Copy this prompt
IMPORTANT: Only modify the [component name]. Do not change any other files or components. Do not modify the styling of anything except what I specifically mention. Now: change the submit button color to blue.
Name the exact element
Instead of 'make the page look better', say 'Change the h1 font size to 32px on the Home page hero section. Do not change anything else.'
Undo if needed
Click the undo arrow in Lovable to revert the last change. You can undo multiple times.
Prevent this next time
The more specific your prompt, the less Lovable breaks. Name the exact component, exact element, exact change. One change per prompt.
Frequently Asked Questions
Name the exact file, component, and element. 'Change the color of the Submit button in ContactForm.tsx to #0071E3' beats 'make it blue'.
Yes. Click the undo arrow. You can undo multiple times to get back to a working state.
