Hyva Child Theme

This automates the entire process of scaffolding a Hyvä child theme in Magento 2, from creating the directory structure to compiling Tailwind CSS. It prompts you for vendor and theme names, lets you pick a parent theme (either Hyvä's defaults or an existing child theme), then generates all the boilerplate: registration.php, theme.xml, composer.json with proper naming conventions, and copies over the Tailwind setup. The smart bit is how it handles the inheritance chain in hyva.config.json, making sure both your parent and the root Hyvä theme get scanned for classes. Saves you from the tedious manual setup and the inevitable typos in theme registration. You'll still need to enable it through admin or CLI, but everything else is done.

Hyvä Child Theme Creator

This skill creates a complete Hyvä child theme with the proper directory structure, configuration files, and Tailwind CSS build setup.

Command execution: For commands that need to run inside the development environment (e.g., bin/magento), use the hyva-exec-shell-cmd skill to detect the environment and determine the appropriate command wrapper.

Workflow

Step 1: Gather Theme Information

Prompt the user to provide the following information:

Vendor Name: The vendor/company namespace (e.g., "Acme", "MyCompany")

Must be PascalCase
Used in composer package name and directory structure
If there are existing Vendor name folders in app/design/frontend or app/code/ offer those in lower case as suggestions

Theme Name: The name of the theme (e.g., "customTheme", "StoreTheme")
