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
The HIBC Health Industry Bar Code is an Europe wide accepted standard for the unique identification in trading but also particular in the field of laboratory and clinics. Because its open data structure, it can be used with different barcode symbologies, for example Code 128, Code 39, Datamatrix and QR Code. The HIBC system could store important data for product identification like manufacturer, product code, batch number, expiry date, production date, serial numbers and quantity. HIBC check determines whether the information in the barcode comply with these regulations, compares the calculated check digit and supports you with other important information about the data in the barcode. ------------------------------------------------------------------------- It has never been easier and cheaper to check HIBC barcodes! ------------------------------------------------------------------------- The main functions ... >>> Evaluation of the HIBC Barcode : This means the reading and checking standard HIBC bar codes either as combined barcodes or as primary plus secondary barcodes >>> The HIBC barcode scanner allows you also to read none HIBC barcodes. In this case, the barcode type and content will be shown. >>> The online help guides you through the functions and displays additional information about the barcode types. >>> The online help will also give a quick overview about the HIBC system and their specifications. ------------------------------------------------------------------------- Believe us, our testing period has shown it: Once you have used our professional app, you won't miss it during daily business life...

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.

BUILD KIT DIFFICULTY
Intermediate
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.
