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
Flip Text Messages is a retro departure board–style message app inspired by classic split-flap displays. Create messages that flip into place letter by letter, just like the old airport departure boards. Use it to write short messages for focus, motivation, or reflection, or to create something visual you can share with others. Messages are saved locally on your device and can be viewed individually or played back as a slideshow of everything you’ve created. Watching words flip into place with tactile haptic feedback makes the experience calm, focused, and deeply satisfying. You can also share your messages as still images or animated GIFs using the system share sheet, making it easy to send a thought, reminder, or moment in a unique retro style. Flip Text Messages includes a dashboard screen built around the same split-flap aesthetic. The dashboard features a retro clock, calendar view, mini message display, mood indicator, focus mode, yes/no decision helper, and a countdown timer. Each element is designed to be minimal, cohesive, and distraction-free. Flip Text Messages does not require accounts, does not track users, and does not collect analytics. All data stays on your device. This app is not a social network and does not display real-world departure data. It’s a simple, intentional tool for words you want to see, feel, and share.

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.
