Does this skill increase token and resource usage?

Yes, by generating N independent solutions simultaneously, it consumes more tokens and compute time, but significantly reduces the risk of critical errors in production code.

What is the N-version programming workflow?

N-version programming is a software engineering technique where multiple independent solutions are developed for the same specification to ensure high reliability and fault tolerance.

When should I use this Claude Code skill?

Use this skill for critical security features, complex algorithms, or high-risk refactoring where correctness and security are more important than development speed.

How does it select the best version?

The skill uses specialized agents to evaluate each implementation against a comparison matrix that ranks versions based on correctness, security, simplicity, and performance.

Security & Testing

Generates multiple independent implementations of critical code and selects the optimal solution through systematic comparison.

About

The N-Version Programming Workflow is a high-reliability skill designed for mission-critical software tasks where correctness and security are paramount. It automates the process of generating N independent solutions using diverse agent profiles—such as conservative, minimalist, and performance-focused—within isolated environments. By utilizing specialized agents to compare, test, and synthesize these versions into a final implementation, this skill minimizes the risk of logical errors and security vulnerabilities in complex systems.
