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
Can’t get enough of Bedroom Battle? Then you’ll love this expansion that contains a total of 100 new sexy challenges and 50 game-related actions. The basic concept of this expansion is very simple: Each time you win a SMALL or HOT reward card in Bedroom Battle you also get to spin a wheel of fortune in the app, and hopefully win an extra reward in addition to the reward you select on the reward card. When you spin the wheel there are three possible outcomes: PINK - You get to select ONE of two random rewards. It can either be something related to the game or something a bit more naughty. YELLOW - You get to select ONE of two seriously sexy rewards. How sexy they are depends on if you've won a small or hot reward card in the game. WHITE - This is the one you don't want to win, as it means you have to choose ONE of two random PENALTIES instead of rewards. Just like in the base game all challenges in the app are designed to work for everyone – regardless of gender or sexual preference. Please note that this app is an expansion for owners of the physical card game Bedroom Battle and NOT a stand-alone game.

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.
