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
Flight Radar is a simple way to see aircraft around you in real time on iPhone and Apple Watch. Using live ADS-B aircraft data and your current location, the app displays nearby aircraft on a radar-style screen showing their position, heading, speed, and altitude. Aircraft move smoothly across the display and can be selected to view additional flight information. Features: • Live radar view of aircraft near your location • Real-time aircraft movement and tracking • Controller mode with detailed aircraft information • Predicted flight paths for selected aircraft • Adjustable radar range and zoom controls • Aircraft trails showing recent movement • Ground and airborne aircraft displayed separately • Map view and radar view modes • Apple Watch support for tracking aircraft on the go • Nearby aircraft list view for quick browsing Whether you're watching traffic overhead, spotting aircraft from your backyard, following flights while travelling, or simply curious about what's in the sky above you, Flight Radar provides a clear and easy-to-use view of local air traffic. An internet connection and location access are required for live aircraft data. Aircraft information is provided by publicly available ADS-B data sources.

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.
