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
Fly calmly by knowing how turbulent your upcoming flights may be. Simply punch in your flight date / number and receive detailed information about how turbulence might affect your journey. If your flight is not leaving for some time, we can save your flight info for you and send you a well-timed turbulence report just before you fly. Our reports are based on publicly available weather data and tell you how strong the expected disturbances might be and how likely they are to occur. Please keep in mind that weather forecasts are not always 100% accurate. Always follow the instructions of the cabin crew during your flight. PLUS — keep your forecast up to date as your flight evolves With Flying Calmly PLUS, your forecast stays current throughout your trip: — Live schedule tracking: your forecast adjusts automatically when your flight is delayed or leaves earlier than expected. — Live route tracking: once airborne, your forecast updates based on the actual route flown, including reroutes and weather avoidance. PLUS is a monthly subscription. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ If you like Flying Calmly, support us by leaving a good review on the App Store!

Validate with people who use this workflow before building.
Hypothesis 2
Partner with more airlines to expand listings.
Assumption to check: Limited flight options compared to competitors.
Validate with people who use this workflow before building.
Hypothesis 3
Add a chat feature for real-time assistance.

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.
