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
Replace your smoking sessions with healthy habits. Smoking is consuming you. But it is easy to escape from it. You can choose to stop smoking by decreasing your daily cigarettes or quitting right now. With this app, you can choose how you quit. When you want to smoke, it means that you are having a nicotine attack. Nicotine receptors in your body are crying for more. But if you can wait for 6-7 minutes at the time of an attack, the urge to smoke will pass. Beat Smoking app is designed to give you healthy things to do instead of smoking. You can track your nicotine level and nicotine attack intervals. These tracking algorithms are based on scientific researches and help you get rid of your addiction more easily. With the new update, you can now use the app offline and you are no longer required to login with an email. You can download and start using it right away.

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.
