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
Orienteering Companion is an outdoor map utility for iPhone, which is primarily intended for orienteering training. The position of the user is displayed in real time on a map image that has been imported from the picture library and calibrated by the user. The app uses the Location Services in the device to get the current position information. The accuracy is at best +/- 5 meters, which requires a good GPS reception. Map images that have been imported are saved in a map collection. A new map image must be calibrated the first time before it can be used. After that, a calibrated map can be used unlimited number of times without any need for recalibration. Features: - Map Sharing: The maps can be shared with other users of the app. - Map Import: Maps in the form of KML/KMZ files (Google Earth map format) that contain calibrated map image overlays can be imported from websites and are ready for use in the app. - Snapshot of Maps: The currently used map, with visible track details can be captured to the Picture library. - Logged Tracks: The user can choose to log the run and see the actual track in real-time. Logged tracks can be exported in GPX format to be used with other applications. - Courses: Orienteering waypoint symbols (virtual flags) can be created using a built-in editor for each map. The user can practice run against the course that has been created in order to "find" the waypoint flags and get a result with found flags, split times and distance information. The course run is logged and the result can be viewed later and exported just like any logged track. Note: - Please read Privacy Policy for information regarding the handling of your Location data. - Your use of this real time route guidance application is at your sole risk. Location data may not be accurate. - Continued use of GPS running in the background can dramatically decrease the battery life. - Maps are normally protected by copyright and the user must make sure to own the right to copy the images of the maps that are to be imported to the app.

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.

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.
