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
Bluetooth Finder helps you find your missing Bluetooth devices. If you misplace your device, this app will let you use your iPad/iPhone that is paired to your device to help find it. Simply install this app, open it, and the app will guide you to your missing device. Bluetooth Finder will help you locate your missing device by trying to look and connect wirelessly to your device's wireless signature. Your missing device may sleep soon after you have misplaced them, so download the app and start searching immediately to ensure you will be able to find your missing bluetooth device. Please check the limitations of the app at the bottom of description to see if you qualify. FEATURES • Find any of your missing Bluetooth devices • Set by step process to guide you to find them • Location approximation and triangulation • A really slick user interface Supported languages: English REQUIREMENTS • Bluetooth Finder requires iOS 8 or later. • Bluetooth Finder will only work on an iPad that is paired to your device. • Bluetooth Connectivity is also needed. • Bluetooth Finder for iPad is needed to find your Pencil. LIMITATIONS OF APP • Bluetooth Finder may not work if you have disabled/re-enabled bluetooth after losing your Pencil. • Bluetooth Finder will may not work if you have restarted your iPad after losing your device. • Bluetooth Finder will not work if you have lost it over a large distance (e.g. lost in train, but trying to find it at home). • Bluetooth Finder works best if you have lost in the last few minutes.

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.
