hyva-create-module — Claude Code skill: Magento 2 module scaffold

What hyva-create-module does

The skill lays out a new module under app/code/{Vendor}/{Module}. It takes a vendor and module name in PascalCase, plus optional description, <sequence> dependencies and composer requirements. From those it generates three files from templates: registration.php, composer.json and etc/module.xml.

Before writing anything it checks that both names start with an uppercase letter and contain only alphanumerics, and that the target directory does not exist yet. If a check fails, creation stops and the error goes back to the calling skill. Kebab-case names for composer are derived automatically: ShoppingCartGraphQl becomes shopping-cart-graph-ql.

This is a utility skill for other skills rather than a standalone generator — it gets invoked when a workflow needs a module skeleton. The bin/magento setup:upgrade step depends on the hyva-exec-shell-cmd skill; without it that step is skipped and you run the command yourself. An existing module directory in app/code blocks the run, so clear the old folder first.
