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.

Boxing Timer is an application designed for your boxing training, sparring and workouts. Boxing Timer gives you a fully configurable round timer on your iPhone™ and iPod® touch. The application can also be used for other sports and training, such as Mixed Martial Arts, Grappling, Martial Arts, Muay Thai, Wrestling and any other sports requiring timed rounds. The application counts each round for you and uses a classic digital display for time. Boxing Timer is designed to alert you of the current period at all times. Your iPhone or iPod touch can be rotated to provide an extra large time display. Bells signal the start and end of each round and also a warning period. Boxing Timer has the following features: • Configurable time periods for the preparation, round, warning period, and rest period • Coloured backgrounds signifying the particular stage of the round • Round counter • Bell sounds are configurable to indicate the start and end of rounds and the warning period • Vibration (iPhone only) to indicate the start and end of rounds and the warning period • Sounds effects and/or vibration (iPhone only) may be turned off • Extra large landscape display • Classic digital time display • Auto-lock can be disabled to prevent screen locking during rounds • Tap anywhere on the screen to start/pause • Timer position can be saved when application is exited • Runs in the background on devices that support multitasking Note: If your rounds are being interrupted by your device's Auto-Lock feature, then please switch "Auto-Lock" to off in your Boxing Timer's Options screen.

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.
