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.

Designed by an Occupational Therapist. First & Then is a very simple app that uses a board with photos to show that one activity must happen before the next can occur. A fantastic tool for visual learners! The idea behind a First & Then board is to encourage a child to complete an activity that they don’t particularly enjoy. The board motivates the child to engage in a less preferred activity, knowing that a preferred activity (or a reward) will follow. For example, the ‘first’ activity may be something such as handwriting, homework, eating vegetables, using the toilet or visiting the dentist. The ‘then’ activity may be playing outside, computer time or a chocolate treat. The App is extremely simple to use, the board is set up from one page, with clear prompts to help along the way. The app allows the user to quickly and simply insert photos from the device’s camera or photo library, meaning that ‘First & Then’ boards can be made on-the-go and with little fuss. Photos taken are saved within the App to use again and again. The app includes a coloured visual timer, that the user can choose to use, to show the child how long they need to spend on an activity. As well as a digital display, the time is also represented by a coloured pie chart. When the pie is green, the child needs to keep going. When the pie turns amber, the child needs to get ready to finish. The pie turns red when it is time to stop the activity. The app also includes a ‘Finished box’. The child can drag the photo into this box when the activity is completed. The App is complete with the option to use exciting tones to reward the child for completing the activity.

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.
