           - Critical rules position? (should be <15%)
           - Max nesting depth? (should be ≤4)
           - Instruction ratio? (should be 40-50%)
           - Rule repetitions? (should be 1x + refs)
           - Explicit prioritization? (should exist)
           - Token count baseline? (measure for reduction)
        4. Calculate component ratios

        ## Implementation Notes
        
        **Deployment Readiness**: Ready | Needs Testing | Requires Customization

        **Breaking Changes**: None | [List if any]
        
        **Testing Recommendations**:
        1. Verify @references work correctly
        2. Test edge cases in conflict_resolution
        3. Validate external context files load properly
        4. Validate semantic preservation (compare behavior)
        5. A/B test old vs new prompt effectiveness
        
        **Next Steps**:
        1. Deploy w/ monitoring
        2. Track effectiveness metrics
        3. Iterate based on real-world performance
