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
WebScan is a tool that allows you to scan and search barcodes at any internet address. You can even use your own URL template. It has it's own build-in fast barcode scanner at the top of the screen and shows the results just bellow it. The scanned bar code will be placed where you put *** in the URL string. To change the address just tap on the menu and select "Set URL" Write your selected web address and put *** just where you want the code to be placed. It could be part of directory name, URL parameter or what ever part of the URL. With this app you can easily make your own barcode scanning solution just by creating a website or service that handles the codes. Then you just write the address of your site and you are all set and done ! The web content will be visible on the same screen under the the scanner. Supported barcode types: EAN13, EAN8, UPCA,UPCE, CODE128, CODE39, Interleaved 2 of 5

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.
