What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Find the best coffee in Brighton. Grab a pint at the best spots on the beach. Find out what’s on this summer. Forget hours of looking around for where to eat or what to do. Brighton Guide’s easy curated lists show you the best spots, walks, and things to do around town. BG also includes six pre-planned full-day itineraries, helping you spend even less time planning your trip and more time enjoying it. Feeling creative? BG also allows you to create your own custom itineraries which you can use to plan your day in advance. Created by local Brightonians, our local tips show you how to save money, get around, and get the most out of Brighton. Unlike some travel guides, we don't hit you with a wall of text, or overload you with information. We focus on the best spots most worth visiting and the most relevant information to help make your trip better. This app provides two key functions: List and Itineraries. Itineraries are one-day trips designed to help take the thinking out of your trip. Each itinerary comes with a set of pre-planned destinations and activities, along with tips and tricks, and a custom map to show you where you need to be. Where pre-booking or pre-planning is required on your part, it's indicated in the itinerary. This guide comes with five pre-planned days out. You also have the ability to create your own as well. Lists are collections of different types of destinations - food spots, walks, shopping activities, and so on. We've put together the very best spots for you (50+), and so if you feel like mixing things up or exploring, look no further. All destinations are included in our custom map, to help you find out what you need to know quickly and easily without spending time searching online.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
