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
qiblih is, in the bahá'í faith, the direction that should be faced during prayers. it points to the shrine of bahá'u'lláh, near `akká. you no longer need an astrolabe or another costly device. your iphone can help you. depending on your model, there are 2 options : - with an iintegrated compass, just wait one or two seconds and your device will point the qiblih. the screen displays "delta" with angular difference. - with an older model or an ipod touch, you'll need a real compass to find magnetic north. then set the top of your device pointing the same direction. the arrow on the device will show you the qiblih direction. the screen displays "compass bearing" with magnetic declination included. no network access is required if you have gps on your unit. double tap on the compass to change its aspect.

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.
