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
Open Microsoft Access databases on your Mac – regardless if they are in the older MDB or the newer ACCDB format. • view, search and export your data • the only universal Access database viewer – supports MDB, ACCDB, MDE and ACCDE • no hidden costs, no in-app-purchases This app makes viewing Access file quick and easy. A convenient search function lets you find what you are looking for. Double clicking rows brings up a record window perfect for reading long text or inspecting images. MDB Viewer plays nice with others: export your database as Excel files, as CSV files, convert it to SQLite, or create SQL dumps. Because all apps have their unique intricacies, the documentation includes detailed instructions for transferring your data to Filemaker, Bento, Excel, Numbers, Open Office, MySQL, PostgreSQL, SQLite and Address Book. While MDB Viewer shows all the data stored in the database, it can not display forms or queries, and it can not modify databases.

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.
