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
Who's the imposter among your friends? Imposter is the ultimate party game of bluffing, guessing, and social deduction. Grab 3-5 friends, sit around one device, and find out who’s lying. How to Play: 1- All players see the same secret word—except one. 2- The imposter only sees the word “Imposter.” 3- One by one, players say a word related to the secret word. 4- The imposter must fake it and try to blend in without knowing the word. 5- Keep giving words and talking until someone thinks they've figured it out. Fun, fast, and full of suspicion—perfect for game nights, road trips, or hanging out with friends. Features: - Play locally with 3 to 15 friends - 10+ categories like food, movies, jobs, and more - 500+ unique words and growing - No accounts, no setup—just start playing - Great for all ages—kids, teens, and adults Built for laughs, bluffing, and epic "aha!" moments Download now and start your next Imposter showdown! https://imposterwho.com/terms https://imposterwho.com/privacy

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.
