Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
GR10 is a long distance route located in the French Pyrenees. The route runs from the Atlantic Ocean to the Mediterranean Sea, across the entire mountain range of the Pyrenees. The route is very well marked with the typical paintings of the roads of GR, the horizontal fringes, a white and the other red. This route is very well prepared and there are many places to sleep in it. To enjoy the maximum it is recommended to travel autonomously with some type of tent. The GR10 is probably the most known transpirenaic route and an incredible way to discover the beautiful small towns of the french Pyrenees. "Digital Hiking Guide" is the proposal of **HIKEORAMA** as an assistant in long distance routes. It includes in a single application all the necessary information in your routes. Maps, meteorology and information of all the points that you will find along the way. All this presented in the most accessible possible way. It will allow you to position yourself on the route and will help you to take better decisions.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

BUILD KIT DIFFICULTY
Intermediate
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.
