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.

Behold, the most comprehensive and awe-inspiring fixed-price birding app for the iPhone, has undergone a stunning transformation! iBird Ultimate has risen to new heights with the addition of the 2019-2020 American Ornithological Union (AOU) standard, making it a true birdwatcher's dream. It is now 100% compatible with iOS 16 and Silicon-based Macintosh. It boasts a vast database of 967 species of birds in North America, 343 species from the United Kingdom and Ireland, 228 species found in Hawaii, and 169 bird species from the enigmatic island nation of Palau. But this is not your ordinary digital field guide, for iBird Ultimate has an incredible new feature that will leave you breathless. iBird Photo Sleuth is powered by artificial intelligence using a neural network, which enables you to identify any bird from any photo you take or upload. Imagine the possibilities! With just a snap of your iPhone or iPad camera, you can unlock the secrets of the winged creatures that soar above us. iBird Pro is a birding encyclopedia at your fingertips, with more information on each species than in any app. And that's not all, for iBird Ultimate offers both photographs and field-marked illustrations for every species. What's more, it has composite illustrations that highlight the important identification markings of the bird family, something that photographs cannot do. But fear not, as iBird Ultimate also includes multiple photos of every species of bird - including the male, female, juvenile, and subspecies - so you can see how they appear in real life. But the real magic lies in Percevia™, the only parametric birding search engine that can turn anyone into an expert birder, with over 35 characteristics that can be searched, such as body color, GPS location, habitat, bill shape, and song type. The beauty of iBird is it always gives an answer; no more “bird not found” messages. Another unique feature of iBird Ultimate is that no internet connection is required to use iBird Pro in the field, making it the perfect companion for birding adventures. And now, with its consolidated architecture, iBird Ultimate’s default North American database can be supplemented with databases of other countries, such as Hawaii or the United Kingdom. You can instantly switch between them inside the app, making it easier than ever to explore the world of birds. But that's not all! iBird Pro offers a range of features that will elevate your birding experience to new heights. With Birds Around Me (BAM), you can see just those species within a radius surrounding your GPS location. Time-of-Day lets you search for birds by activity levels during the day or night, dawn, dusk, and more. And let's not forget Owls of Mexico, which includes illustrations with field marks, range maps, songs, and calls for 16 remarkable Owl species. So, what are you waiting for? Version 13.2 of iBird Ultimate is waiting for you, with 38 new illustrations just waiting to be discovered. The birding world will never be the same again!

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.
