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
We're working to make the place we call home, better. As the largest newsroom in Wisconsin, and a three-time Pulitzer Prize winner, we have an obligation to our community, to tell all the stories that need to be told.

We’re our Milwaukee’s trusted storytellers. We’re here for it. WHAT WE’RE ALL ABOUT: • Journalism that makes our home better by celebrating the good, solving the bad, and investigating the ugly. • Access to Public Investigator, our Pulitzer Prize finalist series of quick-turn investigations. • Access to PackersNews.com, your source for unbeatable Packers coverage. Go pack go. • Sports coverage for locals, by locals: the Bucks, Brewers, Packers, Wisconsin Badgers, Marquette Hoops, and UW-Milwaukee. • Reporting that keeps you informed on the actions of decision makers and the political issues that impact residents. • Get the latest updates on the 2024 Presidential Election, as well as Wisconsin’s U.S. Senate and House races. • App features like real-time alerts, challenging puzzles and lively podcasts, a personalized feed, the eNewspaper, and more. APP FEATURES: • Real-time breaking news alerts • A personalized feed on the all-new For You page • The eNewspaper, a digital replica of our print newspaper Subscription Information: • The Milwaukee Journal Sentinel app is free to download and all users can access a sampling of free articles every month. • Subscriptions are charged to your account at confirmation of purchase and automatically renew each month or year, unless turned off in your account settings at least 24 hours before the end of the current period.

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.
