A product spec, screen plans, and build steps for your coding agent.

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.

Search for an address or the best places nearby both online and offline. Yandex Maps provides information about organizations and helps you reach your destination by car, public transport, bike, or on foot based on current traffic conditions. Search for and select locations: • The largest organization database and filters to refine your search. • Detailed information: contacts, hours of operation, services provided, photos, and reviews. • Floor plans to find your way around Moscow's major shopping malls. • Search for places and addresses without an internet connection (offline maps). • View places saved on your smartphone, tablet, and PC. Custom map settings: • Real-time location of buses, trams, trolleybuses, and minibuses. • Road maps that show current traffic conditions in the city. • Parking layer with the location and cost of official parking. • Street panoramas for a road-side view of any address. • Choose from three map types: Roadmap, Satellite, and Hybrid. Public transport, car, bike, and walking routes: • Pedestrian navigation: paths between buildings, through parks, across squares, and other pedestrian zones. • Bike navigation: road types, underpass and overpass preferences, and highway warnings. • Public transport routes with timetables and estimated time of arrival. • Optimal driving routes based on live traffic conditions and driving options. • Step-by-step instructions with voice navigation. • Speed camera, speed limit, and speeding notifications. • Real-time updates on traffic, road accidents, speed radar, and more. Offline maps: • Driving routes and voice navigation. • Downloadable lightweight maps (minimum storage space, for example, the Moscow map is just 187 MB). • Database of organizations with hours of operation, services provided, and more. • Over 2000 cities in Russia, Armenia, Belarus, Georgia, Kazakhstan, Latvia, Turkey, Ukraine, and Estonia. Information from users: • Mark road events on the map and comment on user submissions. • Regular updates to the Public Map keep you informed about your city. • Write reviews, upload photos, and update information about organizations.

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.
