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.

**Notice what's nearby** You're in a new city, or just exploring your own neighborhood. You don't have an itinerary, but you also don't want to walk past something interesting. Curio is for that. Open the app and you see a map of your surroundings. Around you: pins for noteworthy places — historic buildings, public art, monuments, viewpoints, parks worth a detour. Tap one and read a short summary. Walk a few blocks and the app updates. Curio pulls from open data sources to surface what's actually noteworthy nearby: • **Wikipedia** — over 6 million articles, ranked by global notability so famous landmarks always surface • **OpenStreetMap** — community-mapped monuments, plaques, statues, viewpoints, trails, hot springs, lighthouses, fountains, bridges • **Wikivoyage** — practical travel-guide listings with opening hours and prices • **National Park Service** — every US national park, monument, historic site Choose what to surface: tap any of three interest categories (Culture, Food & drink, Outdoors) to filter. Switch to Driving mode for rural trips with a larger radius and faster auto-refresh. No accounts. No ads. No tracking. All data sources are open and free. Your location stays on your phone. For the curious. For the wanderers, not the planners. For anyone who'd rather take a five-minute detour than miss a story.

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.
