Generating… usually about a minute.
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.

Our goal with Cross Country Ski Montana is simple: to give you an easy-to-use, all-in-one, no-connection-needed, guide to accessing cross country skiing in Montana. We designed Cross Country Ski Montana to app to be intuitive—we want you to spend your skiing, not learning how to use our app. The app is built on a Google Maps-style interface that most everyone is familiar with. That interface includes links for answering the simplest yet most critical questions when you depart home: Where should I go skiing? And how do I get there? Just pick your desired area, click on "directions", and you are good to go! Instead of shuffling through 3 torn paper maps trying to locate yourself you can let that happy voice in your phone guide you to the trailhead, while you instead focus on getting warm before starting out into the snow! We've included every designated cross country ski area we can find in the Montana, on both public and private lands. (If you have one we missed, please let us know and we’ll add it!). The app gets you to the area, plus we provide you trail maps, when available, for each area so you can study the loop trails, distances, and level of difficulty in advance, plus use them to guide your day. Like you, we love cross country skiing so we've included answers to those questions we all have when heading out with our skinny skis on the roof rack. We are laser focused on providing you the best information available. The app answers questions for each area like: • Is there a fee or is it free? • Is the area groomed? Is it groomed for skate skis, track skis, or just packed out? • Who does the grooming? How do I get the latest conditions report? • How many miles of trail are there? • Who owns the land -- is it public or private? • Who manages the area? The Forest Service, a ski club, or is it a partnership between the two? • How do I contact the group managing the area? • Does the ski area allow dogs? • How do I get there? Cross Country Ski Montana answers these questions and more! Importantly, Cross Country Ski Montana is designed to work offline so you don't need to be connected to get the mapping information we provide to get you to your ski area of choice. That's a nice feature when you're on a snowy Montana backcountry road, not a cell tower within 50 miles! There's no need to download a different map every time you take off; nor will we ask you to buy maps—or anything else —once you have the app. Enjoy the snow!

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.
