Can I use this on existing projects?

Yes, the /pkg-init command detects existing package.json files and performs a multi-phase parallel sync to align your project with modern standards.

What tools are used for building and testing?

The skill configures 'unbuild' for optimized bundling, 'vitest' for unit/E2E testing, and 'eslint' with the antfu configuration.

Does it support monorepos?

Yes, it is specifically designed to handle pnpm workspace catalogs and standardized architecture across multiple packages.

What standards does this skill follow?

It follows UnJS ecosystem conventions, preferring specialized packages like pathe, consola, and ofetch over Node.js built-ins for better cross-platform compatibility.

How does it handle CI/CD?

It automatically generates and updates GitHub Action workflows for automated testing and releases using modern action versions (v6+).
