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
A simple, no-frills bible concordance - easy to use, fast and no wireless connection needed! Designed to be quick and easy to use without all the complexity of more feature rich offerings. Easily jump to any verse in the bible and search for any combination of words. Cross-references to related verses are easy to find, just touch the verses with an asterisk (*). Includes the Matthew Henry Concise Commentary - gain valuable insight and a concise overview of each chapter of the bible with just a simple touch. Also includes Gospel Harmony - a handy index to 185 events, teachings, miracles and parables found in the four gospels of Matthew, Mark, Luke and John. The events are organized in sequential order and you can easily search for any term in the list. The list shows you the event description, category (miracle, parable, etc.) and the bible references for that event which you can quickly jump to simply by touching the bible reference. Supports Dark Mode as well as Dynamic Type so the font size changes to match the Dynamic Type settings on your device. The bible texts are stored on your device, no need for a wireless connection. Contains two versions of text, the King James Version (KJV) and the World English Bible (WEB). The World English Bible is a public domain Modern English update of the American Standard Version of 1901 and can be found at http://ebible.org/web/

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.
