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
Convoy is the easiest way to stay connected with friends on the road. See where your friends are in real time, share your location with privacy controls that make sense, and stop losing the group when you are driving somewhere together. Built for car people, road trippers, car clubs, friend groups, and anyone whose friends are always on the move. LIVE LOCATION, DONE RIGHT See your friends on a shared map in real time - who is driving, who is parked, and who is on the way. Convoy is built around how people actually drive together, with live location sharing made for meetups, cruises, road trips, and group drives. PRIVACY THAT MAKES SENSE Choose when you share and who can see you. Use Safe Zones to keep private places hidden, control your visibility, and turn sharing off when you do not want to be on the map. CONVOYS WHEN YOU NEED THEM Heading somewhere as a group? Start a convoy, invite friends, and see everyone on one shared map. Keep track of the group, follow the route, and spend less time asking “where are you?” GROUPS BUILT FOR DRIVERS Create groups for your car club, road trip crew, track friends, campus mates, or family. Invite people with simple codes and keep your driving circles organized. DRIVE HISTORY AND STATS Track your drives, routes, distance, duration, and trip history. Save the drives that matter and look back on where you went. CAR PROFILES Add your vehicle, photo, color, and details so friends know what you are driving. PRIVATE BY DEFAULT No ads. No data selling. No social feed. Anonymous accounts by default, with account deletion available in the app. Convoy is built for: Live location sharing Friend maps Car meets Road trips Group drives Car clubs Cruises Meetups Route tracking Safe Zones Drive history Car profiles Convoy. Stay together on the road. Convoy uses location access for live sharing, convoy coordination, Safe Zones, route features, and drive recording. Continued use of GPS in the background can decrease battery life. Always drive safely and follow local laws.

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.

Expert
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.
