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
SkyWrit turns your airplane window into a discovery experience. As you fly, a live horizon bar shows the mountains, cities, national parks, lakes, and landmarks visible from your seat, updated in real time based on your position, heading, and altitude. Ever slept through the Gand Canyon? SkyWrit knows what's out there before you do. HOW IT WORKS Tell SkyWrit your flight number and which side of the plane you're sitting on. The app loads every notable landmark along your path and begins tracking as you climb. A gaming-style navigation bar slides landmarks into view as they become visible and track them as they pass. Tap any marker to learn more! DISCOVERIES Get your neck a rest. When iconic landmarks enter your viewing window — Mount Rainier, the Grand Canyon, Manhattan — SkyWrit alerts you in advance so you don't miss your moment. A notification fires 2–3 minutes before peak visibility. A cinematic banner appears when you're looking right at it. CAPTURE Photograph the view with landmark labels overlaid. Export a composed flight story to your camera roll and share anywhere. DESIGNED FOR FLIGHTS Works offline. No AR gimmicks — just bearing, distance, and geography done right. Covers most US domestic routes. No account required.

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.

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.
