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.

This app is incredibly simple to use with a clean and efficient user interface. The app automatically learns the store layout as you buy items, and will display them in that order the next time you go shopping. The user interface is optimised to the different actions you perform when creating your shopping list and when using your list. Use Plan mode to create your shopping list: • Items are shown in alphabetical order. • Use item names that are meaningful to you, in any language. • Add a note to an item to assign extra information such as a quantity. Use Shop mode when shopping: • Items are shown in store layout order. • Tap an item to mark it as bought. • Swipe an item to save it for later. • Select Finished Shopping from the action menu when you're done. Key Features: • Simple user interface, optimised for planning and shopping to minimise the number of taps required. • Automatically learns the store layout as you buy items. • Set shop location and get a notification when nearby (not supported by all device types). • Remembers items you have used before. • Add items individually, or by choosing one or more from a list of previously used items. • Send shopping list by mail or message.

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.
