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
Bottles lets you easily manage your wine collection. Perfect for those of us that have a collection of wine. Allows you to rate the wines you open, so that you know which bottles you liked most when purchasing more wine. There are no additional fees, no ads, and none of your data is shared. Add your wine to the Bottles app, specifying the location you store each bottle. Use the app to view lists of your wine, pick a bottle to enjoy, see where it is located, and mark the bottle as opened. Later Bottles can remind you to rate that wine, helping in the future to pick your favorite wines, and helping you to purchase more of your favorites. Wines can be viewed by varietal, winery, vintage, favorites and more. List can be easily sorted and searched. Since your wine data is stored in iCloud, you can safely access your collection from all your iPhones, iPads and Macs. Bottles may be used when not connected to the internet, and your changes will sync the next time you run Bottles with an internet connection. Bottles supports light and dark mode, and your Text Size setting.

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.
