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
你是否厌倦日常的伪装？ 你是否讨厌戴上“面具”的日子？ 这款应用没有画面和有色滤镜，没有生活中的涂涂抹抹。 放下颜值焦虑，放下面具。来这里，记录真实的自己，做真实的自己！ 花皮是一款无画面却可以照亮自己的App，你不需要刻意去摆弄自己。 你是否渴望卸下'完美人设'的重担？花皮是首个以素颜照为媒介的素颜正念约会交友社区，通过真实影像的自我凝视，帮助用户重建与身体的深度对话。 在这里，素颜照不仅是记录，更是一面照见内在光芒的镜子——每一次按下快门，都是对自我价值的重新确认；每一张无修饰的照片，都在重塑你对美的认知。 我们相信：当镜头不再评判你的五官，当滤镜消失后的真实肌理被温柔接纳，你将获得超越颜值的深层自信。这里没有'不够好'的焦虑，只有'我本如是'的勇气。心理学家验证的数据显示：一个人通过持续记录素颜日记，自我接纳度提升67%，社交压力降低58%，83%的人表示'终于敢素颜见重要的人'。这不是美颜相机的替代品，而是重塑自尊的觉醒工具。现在就卸下伪装，让素颜成为你最自信的社交起点——因为真正的光芒，从来不需要面具修饰。

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.

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.
