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
The iPray app was developed by users of the traditional Book of Common Prayer who desired an easy-to-use application of prayer book worship. iPray simplifies negotiating Scripture readings and the appropriate daily prayers following the liturgical calendar of the church, including feasts and fasts, into one, easy-to-understand application. The app was designed with the user in mind, placing the day's lessons at the user's fingertips. Four daily prayer offices are brought to you based on the liturgical calendar and the time of day: Morning Prayer, Midday Prayers, Evening Prayer and Compline. Morning and Evening Prayer are from the English 1662 Book of Common Prayer. Midday Prayers and Compline are from the Canadian 1962 Book of Common Prayer. Daily scripture readings are from the 1922 lectionary revision of the English Prayer Book, and are in the Authorized (King James) Version. The Psalter is the beautiful and memorable Coverdale translation. For those who are unaccustomed to this kind of spiritual discipline, the iPray app provides an easy introduction to structured daily prayer and Bible reading, based on the ancient practice of the Church as refined by the English Reformation. Download this app and enjoy the rich heritage of daily devotion from the Book of Common Prayer. Our thanks to the Anglican Foundation of All Souls' Church of Oklahoma City and David Hill for their support in the development of this app. For introduction videos and more, check out our YouTube page http://bit.ly/iprayBCP

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.
