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
Drive Cycle Pro helps drivers complete standard drive cycles used to prepare their vehicles for emissions testing. Using GPS tracking and voice guidance, the app walks users through each step of a typical readiness procedure — no OBD device required. Features • Hands-free voice instructions for each drive cycle step • Real-time GPS tracking to guide speed, timing, and distance • Drive cycle preview showing estimated time and number of steps • Works with most vehicles manufactured from 1996 onward with an OBD-II system • No login or account setup required Important Information Drive Cycle Pro is an educational and driving assistant tool only. The app does not connect to or read from your vehicle's OBD system. The app does not display emissions monitor status. Successful emissions testing depends on many factors outside of this app’s control. Drive Cycle Pro is not affiliated with any testing agency, car manufacturer, or government entity. This app avoids the use of brand names, proprietary procedures, or any trademarked terms. Privacy and Legal Drive Cycle Pro collects no personal data and does not require user accounts. For privacy and terms of use, please visit our official website. Prepare with confidence. Download Drive Cycle Pro today and follow a clear, guided process to help your vehicle get ready for emissions testing.

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.
