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 Liberty Item Entry App is designed to allow users of Resaleworld's popular Liberty software to enter and update inventory while on the go. Accounts can be added and updated as well. This app allows store employees to move to wherever they need to be with the convenience of a mobile device, while still having the ability access and enter information.This app helps improve productivity and helps to overcome a number of logistical challenges. The Item Entry App is ideal for the following scenarios: adding photographs to large amounts of new or existing inventory; adding large furniture which is difficult to relocate to a PC with a full installation of Liberty software; traveling to estate sales to add inventory; adding and updating inventory stored in a warehouse. The item entry interface includes several design features that are optimized for a touch-screen, smaller display for popular mobile devices. A list of the 20 most commonly used categories speeds up item entry considerably. A graphical trend analysis tool calculates and displays pricing information based on the category and brand of the item being entered, based on the past year's sales data. Adding photographs to items is simple and quick both when using images from the device's photo library or when taking new pictures with the device's camera. This app also allows users to print tags for inventory, to email item lists directly to accountholders, and to view an account's transaction history. This app requires an installation Liberty Software (Liberty REACT, Liberty 5, Liberty 4 Consignment, or Liberty 4 Trading Assistants) and either a qualifying Web Service plan or a stand-alone Liberty Mobile Access license. Please contact Resaleworld with any questions about Liberty Mobile Access eligibility.

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.
