  2. Adjust patterns if too many false positives
  3. Add more rules from NEW_RULES_GUIDE.md

Short Term:

  1. Save rule enable/disable state to server
  2. Export/import rule configurations
  3. Add more security rules (XSS, CSRF, etc.)

Long Term:

  1. Rule effectiveness analytics
  2. Custom rules UI editor
  3. AI-powered rule suggestions
  4. Integration with SonarQube/ESLint patterns
