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
µBrowser is the micro browser for your Apple Watch. µBrowser is the quick way to do some basic browsing on your Apple Watch when it is necessary. While it is limited it is good way to browse the web when you have no other device around. Features: - Open any URL (Entering a URL works especially good with the new Series 7 keyboard) - Search the web with DuckDuckGo - See your last visited pages - Save pages from the history to your favorites - iOS companion app to manage bookmarks - Complications to quickly access the browser from the watch face Please note: µBrowser is a limited browsing experience. At first it is limited by the device size. Then there are limitations regarding Javascript and large webpages. Login on pages will most likely not work. There is no back button (swiping still works) you need to start a new sessions.

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.

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.
