Twenty-five requests for the same room at the same moment: one booking, twenty-four refusals. This post builds the app that does that, from an empty folder to a live URL, with an AI coding agent doing the typing and the Prisma stack doing the rest: Prisma ORM for the data, Prisma Postgres for the database and Prisma Compute for hosting. Prisma's skills tell the agent how the platform works today, one Composer module provisions the database, and one workflow deploys every push.

This build was done with Claude Code and Opus 5.5. Any similar agent or model that can run shell commands and read Agent Skills can follow the same path. Everything here comes from building a template for Prisma's app gallery in October 2026: the prompt, the code that matters, and what each Prisma piece took off your plate.
