Is Claude Code equally good at Hyvä and Luma frontends?

Yes, but the workflow differs. On Luma, Claude Code knows RequireJS, KnockoutJS, UIComponent XML, and Magento_Ui scaffolding, so it’ll write a requirejs-config.js, a .html Knockout template, and the matching component class. On Hyvä, it scaffolds .phtml with Tailwind classes, Alpine.js x-data attributes, and Hyvä_Compatibility-Module bridges for legacy extensions. We have separate slash-commands per stack. See our dedicated Claude Code + Hyvä page for the deep-dive.
