Does this skill increase my token usage?

Yes, because it generates N separate implementations (defaulting to 3), it uses more tokens and compute resources than a standard single-pass implementation, but provides much higher reliability.

How does the skill choose the best version?

It uses an automated analyzer agent to evaluate all versions based on a priority list of criteria: correctness, security, simplicity, philosophy compliance, and performance.

What is N-version programming in the context of Claude Code?

N-version programming is a workflow where Claude generates multiple independent versions of the same feature using different approaches. These versions are then compared to find the most secure, efficient, and correct implementation.

When should I use the n-version-workflow skill?

Use this skill for high-risk tasks where correctness is more important than speed, such as building authentication systems, core business logic, or complex mathematical algorithms.

보안 및 테스팅

Executes N-version programming for critical tasks by generating multiple independent solutions and selecting the most robust implementation through systematic comparison.

소개

The N-Version Workflow skill introduces high-integrity engineering to Claude Code by spawning multiple independent agent subprocesses to solve the same problem using diverse coding profiles such as conservative, minimalist, and performance-focused. This skill is designed for critical software components like authentication systems and complex algorithms, where it automatically evaluates each version against a rigorous comparison matrix—checking for correctness, security, and simplicity—to either select the best-performing version or synthesize a superior hybrid solution.
