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
Ever picked bad numbers? With this app you can set the seed for those number picks with your own "key" - your special word or number combination. When you've set your own key you'll see a little key displayed in the top-left corner. Get that special advantage! To change the count of numbers to select (up to 25) just tap the "Pick" shaded area at the top left. To change the pool of numbers (1-99) just tap the "1-xx" (where x = some displayed number) at the top right. Touch the bottom left icon to invert your numbers. Touch the bottom 2nd from left to pick new numbers. Tap the middle bottom voice button and have the numbers read to you! Touch the gear and the settings menu appears where you can: * Set the orbs to display! * Set if you want odd numbers marked! * Set your private key (random generator seed)! * Show winning stats of other users! * Register your win! * Sounds On/Off * Send me an email directly!

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.
