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
签途（jiewai.top）是一款面向中国护照用户的全球出境规划工具。 它不只是告诉你“能不能去”，而是帮你看清——该去哪、怎么去、从哪里开始准备。 在信息分散、规则复杂的出境世界里，签途把零散的政策、路径与选择，整理成一个清晰、可理解、可对比的整体，让你少走弯路，也少被不确定性困扰。 【探索世界，从方向开始】 不再盲目搜索国家，而是从「旅游 / 工作 / 留学 / 移民」四种人生路径出发。 每一个目的地，都以更直观的方式呈现： 难度、路径类型、核心要求，一目了然。 你可以快速筛选，也可以慢慢比较，找到真正适合自己的方向。 【搜索，不止是查找】 从国家到院校，从签证类型到具体路径， 所有信息被打通在同一套结构中。 当你开始认真做决定时，不需要再反复切换平台—— 一次搜索，就能串起完整认知。 【AI 帮你看清路径，而不是替你决定】 在不同出境场景下，你只需要补充基础信息：目的地、时间、个人条件等。 签途会为你生成一份结构化分析： 包括关键要点、潜在风险、时间节奏等，让复杂信息变得可读、可理解。 你可以反复调整条件、对比不同路径，把决策过程留在自己手中。 说明：AI分析仅用于信息整理与参考，不构成法律或签证建议，具体政策请以官方发布为准。 【无需账号，也能开始】 打开即用，无需注册。 你可以收藏感兴趣的国家与路径，随时回看与对比。 所有重要说明与政策边界，也都在应用内清晰呈现。 【克制的设计，只为更好理解信息】 深色基调与卡片式结构，让信息更聚焦、更易读。 无论是在通勤途中，还是做出重要决定之前，都能快速进入状态。 【适合这样的你】 想出国，但不知道从哪里开始 在多个国家/路径之间反复对比 不想再被碎片信息消耗时间 希望先建立全局认知，再做决定

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
Intermediate
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.
