What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

The Wasatch Backcountry Skiing Map is the iOS version of the popular paper map and website (visit WBSkiing.com). As with the other platforms, the iOS map includes an index to more than 1,000 backcountry locations in Utah's Central Wasatch mountains (i.e., the two Cottonwood Canyons and some surrounding areas). Visit https://wbskiing.com/coverage to see the terrain covered by this map. This is the must-have app for Utah hikers and backcountry travelers. You do not need cell service to use the map and its navigation features. Completely redesigned for modern iOS, the app now features a faster, cleaner interface that's easier to use on both iPhone and iPad. Using your device's GPS, the map displays your current location on a high-resolution topo map with contour lines and slope shading built from high-resolution LIDAR data, dramatically increasing the detail of the terrain and improving the accuracy of the 30-degree slope shading. With a single tap, you can access information on more than 200 of the backcountry locations on the Wasatch Backcountry Skiing Guide website including photographs, skiing difficulty, skinning distance, vertical climb, parking considerations, and more. (This information can be accessed without the app by visiting https://wbsguide.com. It's a free website I publish.) IMPORTANT: When navigating, the "destination arrow" points directly to the destination without regard to hazards such as avalanche paths, cliffs, and rock fall. It is your responsibility to travel in the backcountry safely.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
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.
