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.

With our app, you can easily keep track of all the books you've read. When adding a book, simply click the barcode button on the top right corner of the screen and scan the book's barcode to automatically fill in most of the fields, including the book cover. Have you ever been asked for book recommendations? Our app makes it simple to find and share books with others. Just go to the book details and tap the share button to share with your friends or relatives via text, email, Facebook, Twitter, or any other app on your iPhone or iPad. If you're interested in a book series but can't remember which ones you've read, our app can help. Just open the app and go to the menu option "Book List by Author/Genre," select the Author tab, scroll down to find your desired author, and tap to see a list of their books. You can quickly check if you've read a book in the series or not. You can also click on the series tab on the bottom and select the series from the list and see which books you have read. As an avid reader who averages 50-60 books a year, it's hard to remember them all. That's where our app comes in handy for me! The app allows you to sort your books by Book name, Author, Genre, Series, and Date read, as well as group books by Author or Genre, Year, Rating, and Series. You can also double-tap the book image or tap the zoom button to view the book cover in full-screen mode and enlarge or shrink the image using one or two fingers. We've included a few screen shots of the Books Read iPhone and iPad App to give you an idea of what to expect. Please don't hesitate to contact us via email if you have any comments, suggestions, bug reports, or requests for the app. We're always happy to hear from our users!

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.
