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 merriest way to plan Christmas gifts. The Nice List keeps everyone's gifts, your budget, and the countdown to Christmas morning in one cheerful place. COUNTDOWN A live countdown to Christmas morning so you always know how many days are left to shop, wrap, and get ready. GIFT LISTS Add everyone you're shopping for and jot down gift ideas. No link yet? Just type it or talk it in — so a "she'd love black leggings" thought never slips away. Track each idea from idea to bought to wrapped. PASTE A LINK Drop in a store link from Amazon, Walmart, and more, and the app grabs the photo and name automatically. BUDGET Set a budget per person and watch your spending at a glance, so you stay merry — not broke. MY WISHLIST Keep your own running list of what you'd love, so when family asks "what do you want?" you've already got the answer. Beautiful, festive, and simple enough for the whole family. Make this your most organized Christmas yet.

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.

BUILD KIT DIFFICULTY
Intermediate
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.
