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
FATUM is a powerful yet easy tool to create full-fledged RPG characters. Although built with roleplaying game systems in mind, it’s been developed to fuel other artistic creations, whether you are a writer, a screenwriter or an illustrator. FATUM is beautifully illustrated with exclusive artwork and carefully designed to delight game masters and players alike! Enjoy creating new characters and their own unique stories. In no time you’ll have a full-developed chronicle for your PC (or NPC!) FATUM deck allows you to: - Generate characters and their linked stories in a short time. - Produce a quick yet full story for an NPC (Non Player Character) when suddendly required on the table. - Build a character story on the fly for a game in course. - In case of a story partially created, finish it later quickly and randomly. Cards are divided into six categories: Characters, Backgrounds, Bonds, Events, Places and Races.

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.
