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.

Have you ever had a vacation near the ocean where you wished you could hold your breath just a little longer to discover the wonders of the underwater world? "Hold your breath" is an iPhone exclusive training app that helps you to prolong the duration of your breath holding. The app features the two most known training methods. The first are Co2 tables that enhance your tolerance regarding Co2 levels in your blood. The second are O2 tables which help extending your maximum breath hold time. WARNING: Never train alone! You should always have someone next to you that knows that you are training and understands the risk involved. Never train more than one session per day! Also do not train more than two times a week. Stop the training immediately when you feel uncomfortable. Do not under any circumstances provide a wrong maximum breath hold time. This is used to calculate the suggested session times. Consult with your doctor before starting to train. The training can lead to blackouts, loss of motor control (LMC), serious and irreparable damages to the respiratory system, serious and irreparable damages to the brain, other serious health damage or death. DISCLAIMER: The showed times are only suggestions that do not guarantee any training success. Any training session suggested by the app has to be carefully reviewed by a professional prior to training.

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.
