Does it support argument validation?

Absolutely. It includes patterns for type coercion, custom validation checks, and cross-field dependencies to ensure your CLI tools receive clean data.

How does it handle configuration files?

The skill includes specialized templates for loading configuration files and merging them with command-line arguments using middleware patterns.

Can this skill handle nested subcommands?

Yes, it provides specific patterns for managing isolated option namespaces and complex, deeply nested subcommand structures.

Is it compatible with TypeScript?

While the core patterns are demonstrated in JavaScript, the architectural structures are fully compatible with and easily adaptable to TypeScript CLI projects.

What is the Yargs Patterns skill?

It is a specialized set of templates and best practices for building Node.js command-line tools using the Yargs library, optimized for use within the Claude Code environment.
