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 'Van Gogh in Arles' app reveals the story of the artist as you move from location to location in the marvelous city of Arles. It uses your device's GPS to guide you and to present audio, text and Van Gogh's letters and paintings matched to your location. Arles, in the south of France, is where Van Gogh chose to sketch and paint toward the end of his life. You will be guided to the very spots where he painted the Trinquetaille bridge, Starry Night over the Rhone, the Yellow House, Jardin d’Eté, Courtyard of the Hospital at Arles, Café Terrace at Night, and more. The old Arles is a beautiful city to wander in, but without a guide you'll miss many of the vantage spots and much of the story behind Van Gogh's most productive period.

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.
