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.

画一个形状，看风穿过它的样子。 BreeZ 是一款 2D 风洞玩具。用手指在画布上随手画出任意形状，立刻看到气流绕它流动——涡旋、尾流、分离，都在眼前实时呈现。 画你所想 自由手绘，或一键插入几何形状。拖拽、旋转、缩放，一切直接上手。 风听你的 旋转风向盘 360° 任意角度，风速从微风到暴风。每种形状的气流都不同。 三种视角 流线、粒子、烟缕——三种可视化模式，风的轨迹一目了然。 底层是真实流体物理求解器，你所见的每一缕烟都是实时计算的结果。 BreeZ 不是工程软件，不是教学工具。它是给好奇的人一个安静地看着风流动的小空间

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

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.
