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.

100% Free without any Ads. Cloudy is an application that will change your lifestyle and your daily routine. When you wake up in the morning instead of going to your window and checking how the weather is, with Cloudy you can check the actual weather on your iDevice. Based on your location you will always be up to date on current weather. Also if you're interested, in how was the weather in 1970 or any other date in the past, or you want to plan an event in the future and you wonder how would the weather be, you can do it all with the Cloudy through the Time Machine feature. (This feature works thanks to Machine Learning - analyzing the weather in the past and predicting it in the future.) Other features are: - Informs you when you need to take an umbrella - You will get informed to take a jacket if temperatures are lower - Your walking routine is going to change with Cloudy because it is going to inform you to take a walk in good weather. - When it's dangerous for cold weather and wind or high temperature you are going to be safe with Cloudy. - More than 100+ stickers in iMessage Available only at App Store. Stay up to date and support us for more interesting features. For any help, feedback, or concern, please contact us: [email protected] Twitter: @cloudy_app

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.
