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
"QuickSearch PDF Reader is the tool you didn't realize you needed ... searches are extra fast but it's the interface design that shines ... a terrific app" -- The Unofficial Apple Weblog (tuaw.com) QuickSearch PDF Reader makes it fast and easy to find text in PDF documents. When you add a document, it is scanned in the background, so when you search, results are instant. And as well as searching within a document, you can search across all your documents at once. It’s also a great PDF viewer with a very natural style of navigation. It snaps to page boundaries, yet it’s easy to flick past them. Zooming is straightforward by pinching, or you can double-tap a region of text to zoom to fit. You can easily jump to any part of the document using the scrub bar. And everything is lightning-fast, even on large documents. You can easily get your documents into QuickSearch from other apps on your iPad or iPhone that support the "Open In..." function, such as Mail, Safari, or Dropbox. You can also use iTunes File Sharing to transfer documents to and from your Mac or PC. Full step-by-step instructions are included.

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.

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.
