Can Claude Code scaffold Hyvä Checkout payment adapters?

Yes — this is one of the trickiest Hyvä tasks and Claude Code shines here. Hyvä Checkout 1.x uses Magewire components, not Magento_Checkout’s KnockoutJS. The contract is: Hyva\Checkout\Magewire\Payment\AbstractPaymentMethod for the renderer, Magento\Payment\Model\MethodInterface for the gateway. Claude Code reads your gateway code, generates the Magewire renderer, the corresponding .phtml, and the etc/frontend/di.xml wiring. We’ve shipped Stripe, PayPal, Klarna, Adyen, Mollie, Razorpay and Authorize.Net adapters this way.
