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
Catholic Sword Apologetics is the best app to defend the Catholic Church and answer common questions about the faith. The app covers topics such as Infant Baptism, Papal Authority, Praying to the Saints, the Eucharist, Mary, Purgatory, Faith Alone, Scripture Alone, and so much more using the Bible as it's primary source. Each topic contains a wealth of information to learn from and a list of scriptures to support the faith in a clear and concise manner. Scriptures contain quick key points to emphasize important aspects of the scripture and help make it more understandable. In addition, a further explanation is used to describe the link between all of the Bible passages and ties each topic together. Whether you are a Catholic looking to defend your faith, a Protestant looking to learn more, or a curious bystander, Catholic Sword Apologetics is an excellent tool to have. He must hold firm to the sure word as taught, so that he may be able to give instruction in sound doctrine and also to confute those who contradict it. - Titus 1:9

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.

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.
