What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Something incredible happened where you're standing right now. We built LocoPast because we kept wondering about the places around us. Every street, building, coastline and landscape has a story, but discovering those stories often meant searching through books, articles and websites. LocoPast is a way to open a map and instantly see the history beneath your feet. LocoPast is the location-based history map app. We transform the world into an interactive map of human history. Open the app and discover the battles, revolutions, inventions, disasters, cultural movements, scandals and forgotten stories that happened exactly where you're standing - or anywhere else on Earth. History isn't just something that happened somewhere else. It's all around us. Whether you're exploring your local area, travelling abroad, or simply curious about a place you've never visited, LocoPast reveals the events that shaped the landscapes, cities and communities we see today. With LocoPast, you can: • Discover historical events near your current location • Explore any place in the world • Browse a global, interactive history map • Listen to hands-free audio guides of each historical event or site • Travel through centuries of events connected to real locations • Open source articles for deeper context and further reading Every event is linked to the place where it happened, turning ordinary locations into gateways to the past. As you move across the map, new stories appear automatically, creating a continuous journey of discovery. Explore events including: • Battles and military history • Art, culture and creative movements • Political events and revolutions • Scientific discoveries and innovation • Architecture and landmarks • Religion and belief systems • Crime, scandals and mysteries • Natural disasters and major world events • Industry, commerce and economic history The next time you look at a street, a square, a river or a landmark, you'll know something most people don't: What happened there. Download LocoPast and uncover the hidden history of the world around you.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
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.
