N Version Workflow

This generates multiple independent implementations of the same feature and picks the best one through systematic comparison. You'd use it for authentication systems, critical algorithms, or high-risk refactors where bugs are expensive. It spawns N parallel Claude instances with different personality profiles (conservative, minimalist, performance-focused), runs them in isolation, then evaluates everything against correctness, security, and simplicity criteria. The comparison matrix approach is solid, and it can synthesize hybrids if two versions have complementary strengths. Obviously costs N times the tokens, so it's overkill for CRUD operations, but for security-critical code where you want multiple independent perspectives before committing, the approach makes sense.
