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
Your recipes, always with you. Whether you're following a family classic, trying something new, or working on a weekend bake, all your recipes live in one place — and come with you wherever you go. SCALE TO ANY AMOUNT Enter your flour weight or portion count and every ingredient updates instantly. Cooking for two instead of eight? Doubling a batch for a crowd? No mental maths, no scribbled notes — just the right amounts, every time. COOK WITHOUT TOUCHING YOUR PHONE Hands-free mode guides you through each step of a recipe without needing to tap your screen. Your progress is saved automatically, so if you step away, you pick up exactly where you left off. SWITCH UNITS FREELY Grams, cups, ounces — switch between metric, imperial, and US volume at any time. Cookbook converts ingredients automatically so you can cook with whatever you have on hand. BUILT FOR BAKERS TOO Every baking recipe can display baker's percentages — the ratios that reveal why a recipe works and what to change when you want to experiment. Once you bake by percentage, you'll never go back. WORKS ON IPHONE AND IPAD Your recipes are always available, on whichever device is closest.

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.
