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
Nittany Nights is your nightly guide to what's happening at the bars, restaurants, and live-music venues around State College and Penn State. Every night we check dozens of local venues and pull together the events worth knowing about, so you can open one app and see what's on tonight and this weekend. WHAT YOU GET • Live music and DJ sets, by night • Happy hours and drink specials • Trivia, karaoke, open mics, and venue events • A clean nightly list, sorted so you can scan it fast • Distances from campus so you know what's walkable OPTIONAL NOTIFICATIONS Turn on alerts for the weekend live-music rundown and weekday happy-hour picks. Choose the days you care about, or none at all. Notifications are entirely opt-in and easy to turn off in Settings. WORKS OFFLINE The latest listings are cached on your device, so the app still opens when service is spotty downtown. NO ACCOUNTS, NO TRACKING There's no sign-up and no login. We don't collect personal information, and we use privacy-friendly, cookieless analytics. See our privacy policy for details. Nittany Nights is an independent local guide for the State College community. Listings are gathered automatically and may occasionally be incomplete; always confirm with the venue.

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.

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.
