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
Welcome to Kiddie Bank, the app designed for parents to effortlessly juggle their little ones' pocket money. Keep track of that birthday cash from Grandma, lemonade stand earnings, and more! You can teach your little ones the value of saving while incentivizing good behavior through a reward points system. Kiddie Bank allows parents to easily track monetary gifts and also reward good behavior with points that are worth money. Kids can lose points for poor choices, too. Kiddie Bank encourages children to learn about saving and spending while reinforcing positive habits. Your kids’ points balance will sync effortlessly across any parents' or caregivers’ phones. With seamless syncing capabilities, all parents and caregivers stay in the loop, ensuring consistency in managing their child's financial education. Every penny saved and point earned shapes your child's future and fosters responsible financial habits! Even though this app is incredibly simple, it may encounter issues. If that is the case, don't hesitate to reach out to let us know about any bugs (or feature requests :) ) using the question mark button in the menu bar. Thanks for using Kiddie Bank!

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.

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.
