The build skill. Install it when you want an agent to stand up a complete booking website — not just call the API. It picks the closest official template, scaffolds it, wires it to a store, restyles it to your brand, and deploys it. For exact API calls it defers to the opencals-storefront-api skill.

​
What it covers

  • Choosing a template by booking shape (people vs resources, groups, multi-location).
  • The workflow: scaffold → configure env → understand the SDK wiring → rebrand → verify → deploy to Vercel.
  • Resource-booking (courts, lanes, rooms, equipment): the three conflict rules, allowCustomDuration, and the units × time grid strategy, and multi-location resources with one availability read per location — the VOLT template is the worked example.
  • Rentals by the day (cars, boats, equipment, villas): 1-day base duration with custom duration on a 24/7 schedule, merged availability ranges with a client-side fit, 00:00-aligned slots, handover details as custom attributes. The NOIR Drive template is the worked example.
  • Nightly stays (villas, cabins, guest houses, rooms): a one-night base with custom duration and fixed check-in/check-out times that the API enforces, turnover days, guest and arrival details as custom attributes. The Bali Villa Rentals template is the worked example.
  • Schools and classes (languages, music, coding, tutoring): subjects as collections, levels as variants, teachers as staff, seats left from slot availability, and the online location’s link for a Join button. The Fluently template is the worked example.
  • Fitness and Pilates studios (reformer, yoga, barre, spin): one variant per class × studio × instructor capped at the beds in the room, Full classes inferred from each series’ weekly pattern because the API drops full slots, privates sharing a product pool, and dated workshops. The Tensile template is the worked example.
  • Customising: colour/font tokens, siteConfig, and what comes from the API vs. what you edit in code.
