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.

Take this guide with you when walking the Cape to Cape Track. It has all the information you need to both navigate and prepare for the Track. It's built by local Western Australians who have walked the Track several times and live only a few km from the Track. We know the area! The guide works 100% without needing mobile phone reception or Internet access. The offline maps are very detailed, show the Cape to Cape Track, show where you are via GPS, and are marked up with camping areas, sightseeing, water sources, places to swim, some accommodation, restaurants and food shops, the best beachs, sights and many other points of interest. The App shows you how many kilometres you are from places like camping area and towns, and has an interactive elevation graph so you can see what hills are between you and places. The App has advice on how to prepare for your trip, what gear to bring, when to walk, possible itineraries and suitable food. It has many other features, photos and information, as described below. FEATURES: - Very detailed offline maps. They ALWAYS work, even when mobile phone coverage and Internet are not available. - The map is tuned to look great on a small phone screen and show details that a walker in the bush needs. You'll see details such as minor tracks at map zoom levels where most other maps hide them. So zoom out and tracks don't disappear from your map! Great for your safety and easier for you to navigate even with a tiny screen. - Contour lines are shown on the map as you zoom in a little. - Uses GPS to show your location. - The map has extra markers for towns, camping areas, sights, places where you can get food, attractions, swimming spots and other points of interest. - Map markers also show you where to get water and the location of toilets. - Tap place markers on the map and be shown your distance from them along the track. See how far away that camping area is! - An elevation graph that you can zoom-and-swipe to see all the hills and valleys along the track. - The elevation graph shows your location and has markers for towns, camping and other places. Use it to see if you have to walk up any big hills to get to that next camping area? - Tap town, sightseeing, camping and other markers on the map to get detailed information and photographs for those places. - Has descriptions and pictures of each section of the Track. - Provides information on paid accommodation options. For those who want a bit more luxury than camping! - Has a track overview, and information about camping, drinking water, safety, weather, animals and history of the Cape to Cape Track. - Detailed advice and information on how to prepare for a multi-day trip, when to do your trip, what gear you need and suitable food. - Describes transportation options such as buses and companies that provide shuttle services. - No mobile phone coverage or internet is needed for the App to work. Put your phone in Airplane Mode to save battery power and continue to use the App (your phone's GPS will still work in Airplane Mode). - The App turns off GPS when the screen is turned off, so will not use phone power when you are not using it. - The guide has loads of beautiful photographs of the Track to inspire you! You should never get lost because the maps always work and show you where you are, even when you stray from the Track. The great detail on the maps make it easy to follow bush tracks and paths to get back to the track. This App was built by a small Western Australian software company located only 8 km from the northern termination of the Track. We know the track and the area intimately. We're confident our Cape to Cape Track Guide App will make your trip easier to plan, safer and more fun.

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.
