Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
Smart Quiz — это ежедневная викторина, в которой нужно отвечать всего на один вопрос в день. Никаких длинных тестов и бесконечных уровней: открываешь, думаешь, отвечаешь — все. Завтра будет новый вопрос. Зачем это приложение: Поддерживать мозг в тонусе без перегруза Узнавать новые факты Провести “пару минут в телефоне” с пользой Что внутри: 1 вопрос в день. 2 минуты на ответ: во время вопроса играет фоновая музыка, которая работает как таймер. Одна попытка: ответ фиксируется после подтверждения. Звонок другу, чтобы получить подсказку. Результат и факт дня: короткое объяснение или интересный факт. Статистика для отслеживания прогресса. Шеринг результата в мессенджерах или соцсетях. Как пользоваться: На главном экране всегда находится вопрос дня. Нажми "Начать" и приготовься: у тебя будет 2 минуты. Напиши ответ или скажи голосом и нажми "Ответить". Если нужна помощь — нажми "Звонок другу", выбери контакт и позвони, но таймер будет идти. Посмотри результат, прочитай факт дня и при желании нажми "Поделиться". После ответа вопрос закроется до завтра — на главном экране появится таймер до следующего вопроса. Один день — один вопрос. Smart Quiz помогает держать ритм, учиться понемногу и получать удовольствие от интеллектуальной игры.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

BUILD KIT DIFFICULTY
Starter
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.
