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
专注食光是一个番茄钟软件。开始专注前，你先进行“点单”，从app内的5类26种食物中选择自己想要的。你可以选择“立即送达”，下单后立即开始专注，你也可以选择“预约配送”，选择未来的时间进行预约专注。预约的专注时间到时，app会向你发送通知，提醒你开始。 专注时，没一分钟都可以获得一个专注点数，若点数多于你点的食物所需，就可以将点数存入账户内。专注时不要提前退出哦！提前退出会扣除20点数，也无法获得所点的食物。 专注结束后，你会获得你点的食物、这个食物获得的饱腹度以及一张它对应的贴纸。饱腹度达到百分之百会解锁成就，而贴纸则可以在贴纸池中使用。 app还有日程表功能，上面有每日的专注时间、获得的食物以及未来预约专注活动的记录。 加入专注食光，收获高效的时光！

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.
SUGGESTED BUILD STACK
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.
