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
L’applicazione consente di scoprire la collezione dei Mercati di Traiano-Museo dei Fori Imperiali in modo semplice ed esaustivo, attraverso le storie di numerose opere eccezionali e uniche, veicolate tramite uno storytelling vivace, affidato alle voci dell’imperatore Traiano e del suo architetto, Apollodoro di Damasco, che discutono delle grandi opere architettoniche realizzate e da realizzare. L’applicazione, disponibile in cinque lingue (italiano, english, français, deutsch, español), presenta tre tour tematici con durata predeterminata e una Linea del tempo, con macro-linea del tempo in cui sono inserite le opere del museo e i principali eventi storici correlati. I tre percorsi predisposti possono essere scelti dai visitatori in base alla propria disponibilità di tempo: 1. Arte e potere in età imperiale: 1 ora e 30 minuti 2. Le architetture: 1 ora 3. Personaggi veri e fantastici: 50 minuti Selezionato uno dei percorsi di visita, gli utenti potranno accedere ai commenti delle opere attraverso due strumenti: una macro LISTA suddivisa in base alle sale espositive, identificate attraverso il titolo e un’immagine - o digitando sulla TASTIERA il numero del punto di interesse, il cui riferimento potrà essere facilmente trovato sui pannelli di sala o sulle singole didascalie. Ogni commento presenta un commento AUDIO, una breve GALLERY e la possibilità di accedere al TESTO con lettura facilitata per le persone ipovedenti, dove è possibile cambiare il colore dello sfondo e ingrandire o rimpicciolire il testo.

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.
