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.

Welcome to Radar Sky. Fast, intuitive and visually stunning iPhone and iPad weather radar app helps you prepare for the latest conditions. Major features: * High-resolution weather radar (NEXRAD LEVEL 3, base reflectivity) * Future radar. Up to 60 minutes ahead are displayed in 1 km x 1 km resolution every 5 minutes * Radar map includes areas of rain and snow * Storm Tracks * Active alerts (severe weather warnings) * Storm tracks, future path for the storm * Real-Time U.S. Composite Satellite Animation Radar ƒ is a great application for iPhone and iPad that displays high-resolution predictive weather radar around your current location, allowing you to quickly see what weather is coming your way. Radar Sky proprietary radar mosaics provide radar imagery at the highest resolution on different zoom levels. Radar Sky gives you up-to-date animated radar imagery from the National Weather Service, with coverage for all 50 US states (and Puerto Rico and Guam!). Radar Sky is recommended for those who are interested in weather, astronomy, aviation, hunting, fishing, travel, own or work on a farm or ranch, a private or vacation home, or work or play in a weather-sensitive environment or industry. The radars cannot determine precipitation type (such as rain or snow). Radar Sky uses special algorithms to delineate between rain and snow. Radar Sky shows animated weather, so you can tell if rain is headed toward or away from you, and how fast. A weather radar is used to locate precipitation, calculate its motion, estimate its type (rain, snow, hail, etc.), and forecast its future position and intensity. Radar Sky shows tornado, rain, snow, and hail clouds movement on zoomable maps around your location in real time. Precipitation type is indicated by the color. Green color indicates lesser precipitation while the yellow color code indicates intense precipitations. The color code red is indicative of the most intense precipitations. Blue color indicates snow. Features: * Full, animated radar from the NWS for the entire U.S. * You may all of your locations to the map * Current weather conditions and ten-day forecast for added locations * play, pause animations at any zoom level * fast forward and rewind using manual scrollbar * zoom in and out, drag and scroll * displays current position on the map * multiple map styles - terrain, satellite or standard * supports landscape mode on iPhone and iPad * saves and restores your last position * manual refresh option

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.
