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
It’s not a car. It’s a robotaxi designed around you. Zoox is fully autonomous, all-electric ride-hailing. We’ve created a purpose-built robotaxi to give you a better way to ride. Get the app today and learn what makes Zoox the best ride on the road. HAIL A RIDE Open the app, choose your destination, and your Zoox is on the way. Zoox drives itself — all you have to do is make yourself comfortable. MEET YOUR ZOOX Your carriage-style seating awaits. Zoox arrives, the doors slide open, and you step inside. After you sit down, craft your ideal ride with in-seat controls for music, temperature, and more. NEW FREEDOMS The Zoox robotaxi’s spacious and comfortable cabin is designed to give time, space, and freedom back to you. Plug in, switch off, or throw a dance party. It’s your journey. SENSORS THAT SEE IT ALL The Zoox robotaxi combines cameras, lidars, radar, and long-wave infrared sensors for a 360-degree view of everything on the road. SAFETY AT THE CORE Zoox protects every rider with over 100 safety features that don’t exist in conventional cars, such as an innovative airbag system and a safety-focused active suspension. TRACK YOUR JOURNEY Instantly view your trip progress from the app or the touchscreen at your seat so you’re never left guessing your ETA. STAY IN CHARGE Wireless charging at every seat means your devices arrive as recharged as you do. MIX THE MUSIC Pair your device to Zoox via Bluetooth and enjoy your favorite tunes or podcasts during your ride. Pair just once and your device will auto-connect every time you ride. RIDE WITH CONFIDENCE If you need help, live support from our team is just a tap away. Availability varies by region. Check the app to see if Zoox rides are available in your city. Need help?

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.
