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.

Validate with people who use this workflow before building.
Hypothesis 2
Implement location updates only when necessary.
Assumption to check: High battery consumption due to continuous location tracking
Validate with people who use this workflow before building.
Hypothesis 3
Provide users with customizable alert settings.
Assumption to check: Limited customization options for alerts
Validate with people who use this workflow before building.
Hypothesis 4
Simplify the user interface to focus on key functionalities.
Assumption to check: Cluttered interface with too many features
Validate with people who use this workflow before building.

App Store description
An app designed by and for weather enthusiasts, NOAA SuperRes Radar is the only app in that offers access to stunningly beautiful super hi-resolution radar mosaics for the continental US. SuperRes radar has 4 times the resolution of typical weather radar products (250 meters vs 1000 meters), so you will be able to view storm features that can't be viewed in ordinary radar apps. No other app delivers radar mosaics with this kind of accuracy in such an easy to use package. In addition to SuperRes Level 2 radar, NOAA RadarUS+ offers access to 3 km hourly forecast radar and the following features: - 3 and 6 day precipitation and pressure forecasts from NOAA weather models - Temperature overlay - Snow/mixed precipitation display (only on 1km base reflectivity radar layer) - 7 day forecasts and current conditions -- just press and hold for a second on the radar map. - Severe weather (flash flood, tornado, and severe thunderstorm) warnings. Tap on a warning box to display the full warning message from the National Weather Service. Note: these are *not* push alerts. The app must be open to view the warnings. - Cloud cover and satellite imagery for the continental United States - Advanced radar layers (echo tops, composite reflectivity, and storm total precipitation). - Play, pause, and step animations - Fast zoom in and zoom out - Choice of radar palettes - Multiple map styles (terrain, map, satellite, and hybrid) - Displays time of radar image either as absolute time or relative to the current time - GPS locator that finds and displays your current location - Adjust the transparency (opacity) of the radar or cloud cover overlays - Radar clutter filtering and smoothing - Automatic refresh when new radar or cloud cover data is available - Search for a location by zip code, city name, or address - Legend for radar and cloud cover overlays - Saves and restores your last location and zoom level Note: Radar coverage only includes the continental United States. Alaska, Hawaii, and other US controlled territories are not included. Support: Please follow our Twitter stream at twitter.com/shuksansoft for breaking news and status updates.

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.
