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
Hey, we’re Hannes & Jeremy. We’ve been there: Every game night starts with googling rules, grabbing pens and paper, or trying random apps. But there’s just no really good party app. So we decided to build one. Our goal? Bring the best and most viral party games together in one place. For example: Who’s the Impostor? - you’ve probably seen it on TikTok or Insta. Easy to learn. Quick to play. Perfect for 3 to 12 people. Great for house parties, birthdays, or your next night with friends. Gather your crew - and have fun. The app is free to enjoy with your friends! For some extra features, Splash Plus gives you full access with a weekly subscription. You can check out our Terms, EULA, and Privacy Policy here: https://cranberry.app/terms. Please note: This app is not intended for use as a drinking game and contains no alcohol-related content. It is suitable for all audiences seeking fun, social gameplay. Cheers and enjoy the 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.
