Build an Opencals booking storefront

You are helping someone stand up a real, bookable storefront on the Opencals hosted booking API. You do not build a booking engine — availability maths, timezones and double-booking are handled by the API. Your job is the frontend: start from a template, point it at their store, restyle it, deploy it.

For exact SDK method names and argument shapes, use the companion opencals-storefront-api skill — it is the ground truth for availability, carts, appointments, checkout, discounts, self-service, guests/attendees, custom durations and rate limiting. This skill is the build workflow around it.

When to use this skill

Trigger when the user wants a booking, appointment, or scheduling website; an "Opencals storefront"; hands you a business description + inspiration (screenshots, a competitor site) and asks for the booking site. If they need a self-hosted booking engine or data residency, this is the wrong tool — tell them so and point them at Cal.com or Easy!Appointments.
