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
Your Local NOAA Frequency Guide. Ever wonder which channel you need to tune your weather radio to? NOAA Nearby takes the guesswork out of it. Whether you are at home, on a boat, or traveling cross-country, this app identifies the exact frequency and channel number you need based on your current location. The Perfect Companion for Your Weather Radio Most weather radios use 7 standard channels. NOAA Nearby tells you exactly which one is yours. By using your device's GPS, the app lists the closest transmitters so you can hear the clearest broadcast possible without scanning through static. Key Features: Frequency Discovery: See the exact frequency (e.g., 162.550 MHz) and its corresponding channel (Channel 1–7) at a glance. Distance Tracking: Know exactly how many miles away each transmitter is located to ensure the best signal. Station Details: View call signs (like KEC49) and station locations (like Monterey or San Francisco) to confirm you're listening to the right area. Offline Functionality: Find your channel in remote areas, on the water, or during a power outage when the internet is down. Clean, Dark Interface: Designed for high legibility in any lighting condition. Why NOAA Nearby? Weather radios are incredible tools, but finding the right station in a new area can be a chore. NOAA Nearby is the simplest way to find your frequency and get back to what matters. It’s an essential tool for radio enthusiasts, mariners, campers, and anyone who wants to stay informed.

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.

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.
