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
Free WiFi, anywhere, anytime. The radar scans for free hotspot locations around the world. In most countries, there's a hotspot on almost every streetcorner. In coffee houses, fastfood restaurants, libraries, bars, hotels, etcetera. This app helps you find them quickly, using the built-in GPS of the iPhone. The app leads you to the nearest of over 100,000 wireless hotspots, in 15,000 cities and 132 countries, with the touch of a button. It's WiFi for Dummies. Get your mail and browse the web without being charged. The ideal WiFi-tool for frequent travellers and mobile professionals. The app shows you the nearest free hotspot address, provides directions on Apple Maps, and shows additional information, such as the hotspot provider, phone number and website. You can browse the full database manually by country and city, or choose to automatically show results based on your location. The application doesn’t depend on WLAN scanning, which would limit the range to only 25 yards, but uses GPS to pinpoint all known hotspots up to a mile away. All the wireless accesspoints are locally stored on your iPhone, and GPS usage is also offline available, so no expensive data roaming is needed. When abroad, you save in roaming cost, because you will always find a broadband data connection for your laptop and iPhone. This app will let you get your mail or surf the web as quickly as possible. Just run it and it'll search a free hotspot near you. It doesn't get easier than this.

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.
