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
Visor - magnifier app for iPhone, iPad and iPod touch is a mobile magnifying glass and reading aid for people with low vision. Enlarge difficult to read text by 4 magnification levels and change contrast to 5 different viewing modes. Optionally, turn on the LED flash of your device to help you see better in low-light conditions. Swiping up the yellow plus button reveals screenshot mode. The 3 large, different colored buttons helps you to get quick access to all functions for easy handling. ‣ 2x to 8x magnification ‣ 5 different color contrast modes: full color, black on white, white on black, yellow on blue & blue on yellow with enhanced contrasts ‣ Manual focus on tap ‣ Autofocus on tap and hold ‣ LED camera light ‣ VoiceOver support ‣ Freeze the image to zoom, enhance contrast and save or share the picture without having to hold the camera pointing at the subject ‣ AirPlay Mirroring support beams the image of visor to your AppleTV onto your television or projector ‣ Tested by people with visual impairments and we are always grateful to hear your feedback too. How visor works: Visor uses the built in camera of your iPhone, iPad or iPod touch. Please keep a minimum of 5cm to the object you like to magnify. Otherwise, the camera can not focus the object. Older iPads don't support the LED camera light.

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
Intermediate
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.
