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.

There are hundreds of gps apps. Do we really need one more? Ariadne GPS is more than a simple gps app. Besides offering you the possibility to know your position and to get information about the street, the number, etc. it also lets you explore the map of what's around you. What do we mean by saying "explore"? You'll deal with a talking map. If you have VoiceOver activated on your device, you will be able to know the street names and numbers that are around you by touching them. Just put your finger on the screen of your device, when showing the map and moving it you will be told the info's about the street you're touching. Your position is on the center of the screen. What's in front of you is on the top half of the screen and things behind you are on the bottom half of the screen. You can also explore a different region than the one around you by telling the app the street and the city. You can ask for information about your position at any time, also activating a function, called monitor, that will give you this info periodically (Please read the note below). This app has also got some other useful features that might help when walking or traveling by bus, train etc. If you add your favourite points to the app database, you can be alerted when you get closer than a certain distance to one of them. This app is completely accessible using VoiceOver and gives you access to information that are normally unavailable to people using the speech synthesizer and can be therefore especially useful to blind and partially sighted people. Note: The features of Ariadne GPS are based on the location services and on the Maps server for what concerns the information about the position. This information may not be accurate, due to the location accuracy, which is generally below fifteen metres but in some cases can be few tens of metres and to the Maps service, which might be unresponsive at certain times (Ariadne GPS will tell you if this is the case). The aim of Ariadne GPS is to give you an idea of your position and what is around you. Please do not completely rely on it. Please note that the use of GPS running in the background can dramatically decrease battery life. For more info and suggestions please visit http://www.ariadnegps.eu

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.
