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
Welcome! You are about to explore one of America’s most interesting and fascinating areas… the New Orleans French Quarter. Your host for this SelfTour is Grammy winning Blues artist Chris Thomas King. In the hit movie "Oh Brother Where Art Thou" Chris portrays the skilled blues guitarist who claims he sold his soul to the Devil. Chris knows the French Quarter and its music. And he will tell you about both… including Jackson Square, Bourbon Street, Pirate’s Alley, Preservation Hall, the VooDoo Museum, famous homes and legendary sites that attract millions of visitors annually. This is a complete circle tour, so you can join the tour at any location, stop anywhere along the way and continue again on at your own schedule. You can even skip locations you may not be interested in. For more instructions go to our website SelfTour.Guide. Here you'll also discover more great SelfTour audio walks, and drives… and you can leave us your comments. If there's a tour worth taking, it's worth taking a SelfTour. We remind you to take caution crossing streets and alleys in this congested traffic area of New Orleans. Now… Let's explore this fabulous French Quarter!

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.
