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.

"Kids learn about Animals" is an educational game for children aged 1 - 4 years from the series “Little One Learns Words”! Together with your child, you can watch wonderful images of different animals, all while learning their names and listen to the animals’ unique sounds! These carefully selected photographs allow your child to not only learn the names of the various animals, but also glimpse into the animal’s beautiful world and everything it offers! After your child looks over and experiences the flashcards, there is a fun game waiting for them, which tests how much they’ve understood. Regardless of the number of correct answers, the player earns stars and young talent is rewarded with thunderous applause and balloons! A significant feature of this app is that there are no unrealistic drawings. Instead, full-length beautiful pictures are used that resemble actual animals (as they look in real life), which helps the child easily remember their names and features. Do you have older children in primary school? If so, this educational game will also come in handy for them because in addition to Spanish, the app supports English, German, French and other languages. Playing these types of games with flashcards has been proven to aid students in quickly learning a foreign language. They can discover new words and are able to easily impress their teachers and classmates! Your child doesn’t even need to know how to read with this app! Its simple interface and voice prompts allow even the youngest kid to play and learn by themselves! After playing the game, be sure to visit the zoo or pet store with your child – you’ll be happy and impressed as they present their newly acquired knowledge of all the animals they see! The app can be used as a supplementary teaching aid in foreign language instruction. Supported languages: English, Spanish, French, German, Russian, Polish, Ukrainian.

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.
