Ready-to-use prompt for Cursor

Copy this prompt, attach your JSON report, and send it to Cursor:

I've added my Lighthouse JSON performance report for [your-site.com] to this conversation.

Please help me fix the performance issues directly in my codebase:
1. Identify the 3 highest-impact issues from the report
2. For each issue, show me the exact code change I need to make in this project
3. Reference the file paths and component names you can see in my workspace
4. Prioritize changes that will fix my LCP score (currently [X seconds])

Generate the actual code changes, not just suggestions.
