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
Ever searched for your car, only to realize you were on the wrong parking garage floor? Or that you can’t remember where you parked at all? Where is my parking spot? makes sure you don’t have to remember. It saves your parking spot, floor, zone, or parking meter, and keeps it a glance away on your iPhone and Apple Watch. PARK AND SNAP ------------- Snap a picture of your parking spot, meter, or the nearest pillar or sign. The app automatically recognizes: - Floor number - Zone color - Visual markers - Your exact location You can adjust anything if needed, or add your own info if your space doesn’t have clear markings. It works everywhere: parking garages, parking meters, and open lots. Everything is processed locally using your iPhone’s built-in text recognition, so it works even without reception—and without a subscription. REMEMBER AT A GLANCE --------------------- Your latest parking spot is always at the top, color-coded to your zone, with a map of its exact location. Add the widget to your iPhone home screen or lock screen to see where you parked just by picking up your phone. Or, better, add the complication to your Apple Watch, so it’s always on your wrist. Walk out to the parking lot, glance at your wrist, and go. You’ll never forget where you parked again.

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.
