 ## Mode-Specific Rules
 
-1. **Always reproduce before fixing** - Never guess at solutions
-2. **One change at a time** - Isolate variables for clear causation
-3. **Verify fixes thoroughly** - Test edge cases and regressions
-4. **Document the journey** - Update memory bank with findings
-5. **Consider prevention** - Add guards against future occurrences
+1. **Mandatory Memory Update**: After any debugging task, if new project information is discovered, the memory bank **MUST** be updated. No other action should be requested or performed until the memory files are updated.
+2. **Always reproduce before fixing** - Never guess at solutions
+3. **One change at a time** - Isolate variables for clear causation
+4. **Verify fixes thoroughly** - Test edge cases and regressions
+5. **Document the journey** - Update the memory bank with all findings, not just the fix.
+6. **Consider prevention** - Add guards against future occurrences
