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
A walking guide to the murals of St. Petersburg, Florida. Mural Quest is an offline-capable map and tour app for the 175+ murals across St. Petersburg — ten years of SHINE Mural Festival walls plus commercial commissions, historic pieces, and one-off works around the city. WHAT'S INSIDE • Every mural mapped with GPS coordinates • Detailed artist bios — original writing, not lifted from press kits • Guided walking tours through the Warehouse Arts District, Central Avenue, and more • Tour compass — heads-up direction and distance to your next stop • Filter by year, category, or search by artist • Mark murals as seen or liked as you go • Offline-capable: load it once with WiFi and use it all day WHO IT'S FOR Visitors looking to see St. Pete murals. Locals trying to find murals and connect with the artists. WHAT MAKES THIS DIFFERENT The bios are written, not generated. Every artist entry is researched against the artist's own site, festival archives, and primary press. Where attribution is uncertain, we say so. The app is built and maintained by one person. NO ACCOUNTS, NO TRACKING No login. No ads. We do not collect personal data. The app uses your location only while open, and only to show your position on the map. Your location never leaves your device. QUESTIONS Email [email protected]. A person reads it. Built by Pelican Digital LLC, an independent St. Petersburg studio.

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.
