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
Not all wine is vegan. Many wineries use animal-derived fining agents like egg whites, fish bladder (isinglass), gelatin, or casein to clarify their wine before bottling. Most labels don't mention it. Vegan Vines tells you the truth about what's in your glass. Just scan the barcode on any wine bottle. Vegan Vines gives you an instant answer. HOW IT WORKS 1. Point your camera at the barcode on the bottle 2. Confirm the scan 3. Get an instant verdict: Vegan, Not Vegan, or Unknown YOUR WINE HISTORY Every wine you scan is saved to My Wines automatically. Filter by vegan status, mark your favorites with a star, and tap any entry to pull up the full details again. No rescanning needed. FOUND AN UNKNOWN WINE? If a wine isn't in our database yet, you can submit it. Snap a photo of the front and back label and we'll research it and add it. No account needed. HONEST AND SIMPLE No ads. No tracking. No account required. Your scan history lives on your device and never leaves it. Built by a vegan, for vegans. Because you deserve to enjoy your wine without the guesswork.

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.
