Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Hit the Button Math is an app designed to help develop mental math and calculation skills. The app is aimed at 5-11 year olds. There are 166 different game modes of varying difficulty so it is useful throughout grades K-5. Answer as many questions as possible in minute-long games, or you can now practice without the pressure of a countdown timer. Questions are randomly generated which means it is very replayable. The game has been carefully designed for children, with large, widely spaced buttons. We recommend that young children play on a tablet. Six main topics are covered: * Times tables - up to 10 or 12 * Division - up to 10 or 12 * Square numbers * Number bonds * Doubling * Halving Between these topics, the four standard arithmetic operations are covered: addition, subtraction, multiplication and division. You can create up to 30 player profiles per device to track an individual's scores. If you prefer there's also the option to play as a guest. All data is stored locally on your device so you don't have to worry about privacy issues. We've also made it very easy for children to quickly switch between profiles after playing a game, if they're sharing a device. After each game, the score achieved is displayed along with the child's high score. Bronze, silver or gold stars and trophies are awarded depending on the score achieved in each 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.

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.
