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
Bheema Tanpura, is a concert quality tanpura synthesiser. The app supports 2 accurately tuned/synthesised, tanpuras each with 6 strings and other advanced controls, all on a single page. I am a signal processing engineer by profession and Hindustani classical singer by passion. I have developed this app after rigorous analysis of the resonance of instrument. Connect your device to good speakers and enjoy the sound in high fidelity. Ideally place the speakers at least 3 to 4 feet away for the best effect. This version contains several digitized tanpura profiles. Use them and adjust the tempo/pluck-style to get the best combination that suits your taste. Two full octaves are now supported. Use the higher pitches with caution as they may sound little shrill and are suitable for use only with instruments. * About Bheema Tanpura * "This application takes its name from one of the greatest hindustani classical singers of our times, Pt Bhimsen Joshi, the maestro of Kiraana School of North-Indian classical music. He has been an inspiration for me and I belong to his school of Music; this software is a tribute to that great personality" Enjoy the Naada of your new pair of tanpuras Mukunda

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.
