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
My Pollen Forecast Pro is the best app for tracking the pollen count and your allergens. With a sleek modern design, you can view hayfever forecasts for the upcoming days and keep a diary of your symptoms. By using the app you will become more prepared for any allergy or asthma difficulties you could experience. - Shows a map where you can see which areas have the highest pollen count! - Several day pollen forecast including temperature, wind and humidity! - Use the app as a tracker for how you feel to monitor your symptoms over time. - Discover which pollens you are most allergic to by adding diary entries frequently. - Receive push notifications either daily or when the pollen count is expected to be high! - Full support for the latest iPhone and iPad models. - Pro version offers the same great functionality of My Pollen Forecast but is ad-free, includes widgets and also includes support for Apple Watch to check the pollen count on the go (including an Apple Watch complication)! If you want the most efficient way of keeping up with pollen forecasts and counts, then My Pollen Forecast Pro is the right app for you. This version is similar to apps such as WebMD Allergy and Pollen.com. * The app currently only supports the contiguous US and the UK. States such as Alaska and Hawaii are unfortunately not supported.*

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.
