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
The Garmin Drive™ app is a simple and convenient app solution for the latest Garmin automotive navigators and dash cams. Visit garmin.com/driveapp for a list of compatible devices. For compatible navigators, the Garmin Drive app provides real-time information for traffic, parking, advanced weather, and photoLive traffic cameras, in addition to smart notifications from your Bluetooth-enabled mobile device. For compatible dash cams, the Garmin Drive app provides quick access to camera controls, settings, and recorded footage. Up to four dash cams can be wirelessly connected with the Dash Cam Auto Sync feature to provide comprehensive coverage around a vehicle, offering various viewpoints recorded by the multiple cameras. The Garmin Drive app can create a “picture-in-picture” video from any two perspectives at the same time, making it easy to review video and also share videos with friends, insurance agencies, or legal authorities. Garmin Speak™ and Garmin DriveSmart™ 65 with Amazon Alexa are two Garmin products that bring what you love about Amazon Alexa to your vehicle. Just ask Alexa to hear music, news, and more. Also, enjoy Garmin turn-by-turn navigation. Stream the audio (music and other responses) from your vehicle’s stereo when you connect Garmin Speak to your stereo using Bluetooth® or AUX. Older Bluetooth-capable Garmin navigators are compatible with the Garmin Smartphone Link app, and older Wi-Fi-enabled Garmin dash cams can access video footage through the Garmin VIRB app.

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.
