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
Having trouble booking a Global Entry interview? This app alerts you when slots open up. Appointments don't last long, so use this app to help you snag one. No login or account creation is required to use this app. 1. Download the app from the app store and open it. 2. Tap one or more nearby interview locations and enable alerts. 3. You'll receive a push notification when an interview slot is available with the constraints you set. This app does not book an appointment for you. It does not interact with your Global Entry account in any way. The sole purpose of the app is to help you book your Global Entry interview at busy locations. You are responsible for booking your interview. The app only alerts you when slots are available. Keep in mind that certain locations are heavily booked and open slots disappear quickly. Global Entry is a registered trademark of the US Department of Homeland Security. This app is not affiliated with, endorsed by or supported by any government agency or entity.

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.

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.
