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
Do you want to see your device type itself? Don't you just hate it when your device plops a whole bunch of text down at the same time? What if I told you, there's an app/keyboard that lets your device TYPE ITSELF, LETTER BY LETTER! I repeat. Letter. By. Letter. What's even better, is that you can vary the typing speed to your liking too! That app, my friend, is THIS APP. Just copy a portion of text, and instead of hitting that bland, uninteresting Paste button, switch to the "Auto Typist" keyboard, and see your device type on its own. ---- AUTO TYPIST ---- - When simple pasting's just not your style - For fans of the automaton Intended for entertainment purposes. Who wouldn't want to see their devices type themselves once in a while, right? * Not held responsible for any potential mischief. ** Privacy Disclaimer : This app DOES NOT store your pasteboard data anywhere. Rest assured that it is safe.

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.
