Generating… usually about a minute.
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.

Bring the taste of Jamaica to your kitchen with CookJA — the ultimate Jamaican recipe app, built by Jamaicans, for the world. Whether you grew up eating rice and peas every Sunday, you're homesick for a taste of the island, or you just fell in love with Jamaican food and want to learn how to make it yourself — CookJA has you covered. Every recipe is authentic, detailed, and easy to follow, from classic staples to dishes you won't find anywhere else. This isn't just another generic Caribbean cookbook app. CookJA was developed and designed by Jamaicans who know the food, the culture, and the flavors — because real Jamaican cooking deserves real representation. What's inside: Authentic Jamaican Recipes — Step-by-step instructions and full ingredient lists for your favorite Jamaican dishes, from jerk chicken and oxtail to curry goat, ackee & saltfish, festival, and beyond. Clear, Concise Instructions — Every recipe is written to be easy to follow, whether you're cooking Jamaican food for the first time or recreating a dish from memory. Caribbean Food Glossary — Not sure what a breadfruit is? Never cooked with scotch bonnet peppers before? CookJA's built-in glossary covers fruits, vegetables, spices, and meals from Jamaica and across the Caribbean islands — so you always know exactly what you're cooking with. Ingredients You Can Actually Find — Recipes are written with real kitchens in mind, with notes on ingredients and how to source or substitute them. Who is CookJA for? CookJA is for the Jamaican diaspora missing home-cooked meals. It's for the food lover who tried jerk pork at a restaurant and has to know how to make it. It's for the traveler who spent a week in Montego Bay and came back craving everything they ate. It's for anyone who wants to cook something real. Available on all iPhones and iPads.

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.
