What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

splitcheck – check splitter / tip calculator there may be other apps that allow you to split a check among different parties, but this app was designed to allow you to quickly enter your check and get the results fast and accurately. it does one thing and does it well. you don’t want your bother-in-law leaving the table before he knows what he owes. no more wondering why we’re still $5.00 short. enter items from your restaurant check into splitcheck. as you enter an item’s price, another line is automatically entered below, ready for you to touch and enter that next item. the goal of the data entry method was to minimize ‘touches’ so data can be entered fast and easily. enter who purchased the item next to the price of the item, either as you go or after all the items have been entered. use initials, names, or numbers to make the entry easy. (it is case insensitive to make it even easier.) if an item was split, enter the same names or initials separated by a space. depending on how many shared items are entered 50 or more payees can be entered! if an item is split among all parties, you can leave the payee’s box blank and the program assumes that the item is to be split among all uniquely entered payees. touch the ‘tax’ button to enter the tax amount. the tax is proportionately calculated and applied based on the amounts each person spent. use the spinner to select a tip amount. the tip for each person is shown separately. you can even apply a coupon value to one person or split among two or more people. enter the value of the coupon and press ‘coupon’. as with other entries, the value of the coupon can be assigned to one or more payees. (the tip will be calculated based on the bill without the coupon value subtracted.) at any time touch ‘show splits’ to display how much each payee owes. the results are sorted by name with the bill, tip and total displayed for each. touching ‘details’ displays the breakdown for each payee. 1.5 initial release

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
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.
