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.

Optimize AR experience for a wider range of devices.
Assumption to check: Inconsistent AR performance on older devices.
Validate with people who use this workflow before building.
Hypothesis 3
Simplify onboarding and improve UI guidelines.
Assumption to check: User interface can be confusing for new users.
Validate with people who use this workflow before building.
Hypothesis 4
Provide detailed descriptions and history for each satellite.
Assumption to check: Limited information on satellites.
Validate with people who use this workflow before building.
App evidence
Original App Store material. Ratings and screenshots describe the existing app, not proof of demand for your version.
App Store description
Discover more than 450 satellites in the sky at night or even during the day. Check satellite passes over your location. Receive alerts in your device. Save in your calendar when you will see them in your sky. You can watch 11 types of satellites: International space Station (ISS), Other Space Stations, brightness satellites, Russian in LEO orbit, Military, NOAA, Iridium, GOES, TERRA, AQUA and LANDSAT. All in augmented reality to know the position even with clouds and night and during the day.

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.

BUILD KIT DIFFICULTY

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.
