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
We are very pleased to present You an amazing App that uses the latest Apple technology - Create ML! Create ML is a Machine Learning Model, which we pretrained with ~4’000 road signs from over 30 European countries! Combined with this amazing Apple technology, this App: - allows you to scan road signs - then processes them using the pretrained Create ML Model - suggests what the road sign means and shows you its interpretation and accuracy of each analysis - presents what are the variations of this Road Sign in other European countries. In addition, this application shows the Road Signs in each of over 30 European countries. This application allows you to analyze about 4’000 Road Signs of more than 30 European countries, with descriptions and images. This application is based on the latest information and materials available in the largest library in the world - Wikipedia (wikipedia.com). This application processes and analyzes data in order to present advanced analysis in an appropriate, synthetic and user-friendly, visualized way. Caution: This application is for educational purposes only and may not be used as a basis for interpreting road signs and applying the rules of the road in any country. Because each country has its traffic code and it is the basis for the application of road traffic rules, the authors of this App do not take any responsibility for the consequences of its use.

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

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.
