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
Pipe data provides quick and convenient access to comprehensive dimensional, weight, and piping design data for 72 common ASME piping components. Known for its accuracy and up-to-date information since its inception in 1996, Pipedata has become a trusted resource for individuals and corporations worldwide. It offers detailed specifications based on the latest ASME standards, covering Metric, U.S. Customary Units, and Inch Fractions for NPS and DN pipe sizes. The platform includes weights for pipes, valves, flanges, and other piping components, ensuring a complete resource for engineering needs. Key Features: Extensive ASME specifications, including pipe dimensions (ASME B36.10M/19M-2004), flanges (ASME B16.5-2013), and fittings (ASME B16.9-2007). Supports welded, threaded, and socket-welded fittings. Provides detailed valve dimensions and weights (e.g., gate, globe, butterfly, check, and control valves). Incorporates non-metallic rings, spiral wound gaskets, and RTJ rings for various flange types. Includes flange weights, pipe weights, and detailed valve dimensions for multiple configurations. Pipedata is an essential tool for professionals in the piping industry, combining accuracy, efficiency, and versatility in one intuitive interface.

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.

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.
