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
From the developers that brought you the best-selling Camera+, and Camera+ 2, Macro by Camera+ will instantly be another staple of your digital camera bag. The goal of Macro by Camera+ is to take the fuss out of taking amazing-looking close-up photos. The app intelligently chooses the best lens for your shot, and gives you just the right tools to make your subject shine. And there's no hardware envy required: Macro is compatible with any iPhone that can run iOS 15! The controls in Macro by Camera+ are laser focused and powerfully aimed at getting the perfect up-close image in crystal clear focus. It includes manually controlled focus and EV so you can precisely control the focus and brightness of your photo. It also features several handy on-screen tools to help you frame and plan your shot. - Focus peaking outlines what parts of your photo are in focus. - Grid helps you position your subject on the screen. - Histogram lets you visualize the relative brightness of your shot. After you carefully frame and shoot your photo, Macro by Camera+ will intelligently apply our secret formula to make your subjects crisp and contrasty, without making them look unnatural! And because Macro by Camera+ saves directly to your Photo Library, your shots are instantly available for editing in your favorite software (like Camera+ 2).

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.
