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.

*** WINNER for Best Elementary Student App at BestAppEver.com *** Readers' Choice Top 10 at SmartAppsForKids.com TeachMe: 1st Grade is the third installment in the popular TeachMe series of educational apps. TeachMe: 1st Grade teaches four age-appropriate subjects to first grade children: sight words, addition, subtraction and spelling. Learning subjects align with common core standards to help your child get prepared for 1st Grade. Parents can review performance history for each subject to check how their child is doing. TeachMe: 1st Grade keeps children engaged with a unique reward system where children earn coins by playing learning games at the school. They can move around the rest of TeachTown to spend their coins on fun rewards. Children can collect stretchable shapes at the Shape Store, visit their virtual aquarium at the Fish Store, and decorate different scenes at the art store. The simple and intuitive user interface is designed to be child friendly, which allows children to play without help from an adult. An animated teacher (Mimi Mouse) gives verbal instructions and feedback to encourage the child to learn and succeed! In addition, the learning screens are colorful, fun and rotate between four different subjects so children don't get bored. Children write their answers for math and spelling questions and TeachMe: 1st Grade reads them. If your child needs help, TeachMe: 1st grade will show them how to write the correct answer including the proper stroke order. TeachMe also includes a virtual keyboard input option. Each child has an achievements screen which motivates and encourages learning by showing progress and levels for each topic. Parents can use this screen to quickly see progress of their child. Parents can select which subjects they want, set different difficulty levels, and even choose specific questions. Parents can also review performance history for each subject to check how their child is doing.

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.
