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
Greetings, Time Cadet, and welcome to SPACE-TIME ADVENTURE TOURS: Central Park! This AR-enabled app guides tour goers on an hour-long adventure through New York City’s Central Park to discover its hidden history and enjoy a few unexpected surprises along the way. After you have downloaded the app, make your way to Central Park. The start of this tour is located at 72nd Street and 5th Avenue, the entrance to the park once known as “Inventor’s Gate.” From there, your mobile device will transform into an official Walkie-Talkie Time Machine™, an all-in-one Space-Age interface that will lead you on a multi-stop tour showcasing many of the park’s main attractions. This tour includes augmented reality (AR) and spatial audio to enhance the experience and provide accessible navigation, so remember to charge your battery and bring your headphones. ACCESSIBILITY FEATURES: All SPACE-TIME ADVENTURE TOURS are designed for accessibility and include features for non-visual gameplay for blind and visually impaired users as well as haptic feedback for deaf or hard of hearing folks. This app is VoiceOver compatible. To help with navigating from stop to stop we have provided optional spatial audio beacons. These beacons emit a bell sound that corresponds with the next stop on your map. Headphones are required to unlock this feature. Verbal directions are also included to assist with wayfinding. Interactive buttons and gestures have also been simplified and designed to be forgiving. For example, when prompted to press the “big red button” you can press anywhere on the lower portion of the screen. Please reach out to our team to give any feedback on your experience.

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.

BUILD KIT DIFFICULTY
Intermediate
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.
