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
Read faster and more easily with our digital reading technology, which has has won awards from Stanford and United Nations! Here's how it works: instead of using plain black text, we display text using eye-guiding color gradients. These gradients flow from the end of one line to the beginning of the next, so that when you move your eyes from right to left, they're automatically drawn to the appropriate line. Vision, literacy, and medical experts agree that BeeLine Reader improves reading speed and reading ability for readers of all ages and skill levels. It is particularly helpful for readers with dyslexia, ADD, or vision impairments—some readers are able to read over 50% faster with BeeLine. Find out how much it will help you by taking the BeeLine Reading Challenge on our website: www.BeeLineReader.com. Included app functionality: Read with BeeLine in Safari using our BeeLine Action Extension; save articles for later using the BeeLine Share Extension; and browse the web with BeeLine on select popular websites (AP News, Reuters, and Medium.com) within the BeeLine app. Never used an extension before?

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.
