# How to Validate Future Code Changes
## The Validation Prompt
After you finish development, copy and paste this ENTIRE prompt to your AI assistant:
---
I have finished developing new features in the ATOMS Flutter application.
Please analyze my changes against the optimization patterns in ATOMS_OPTIMIZATION_COMPLETE_GUIDE.md
Validate these 8 areas:
1. PROVIDER ANALYSIS - Check if new providers use lazy: true and have proper dispose()
2. WIDGET REBUILD ANALYSIS - Find Consumer usage that should be Selector
3. API CALL ANALYSIS - Verify lookup APIs use useCache: true and JSON parsed once
4. MEMORY MANAGEMENT - Check controllers/connections are disposed properly
5. CODE QUALITY - Verify kDebugMode guards and error handling
6. PERFORMANCE REGRESSION - Check metrics: launch under 1.5s, memory under 120MB, dashboard under 2s
7. DETAILED REPORT - List issues with severity ratings and fixes
8. SUMMARY - Grade code quality and approve or request fixes
Be thorough and provide specific line-by-line fixes for any violations.
---
That is the prompt to use!
