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
Immerse yourself in the world of Dune. Experience the ultimate blend of strategy and intrigue as you navigate the treacherous landscapes of Arrakis in the award-winning board game Dune: Imperium! Battle online, locally with AI, or against the formidable House Hagal. Earn Achievements that showcase your prowess as a leader. Embark on more than a dozen Challenges that will test your wit and cunning. Compete for badges in the rotating Skirmish Mode where no two games are the same! Control the Spice. Control the Universe. Arrakis. Dune. Desert Planet. Raise your banner above the vast wasteland before you. As the Great Houses of the Landsraad marshal their forces and their spies, whom will you influence, and whom will you betray? A tyrannical Emperor. The secretive Bene Gesserit. The shrewd Spacing Guild. The ferocious Fremen of the Deep Desert. The power of the Imperium can be yours, but war is not the only way to claim it. Dune: Imperium blends deck-building and worker placement in a deeply thematic new strategy game where the fate of the Empire hangs on your decisions. Will you seek political allies or rely upon military might? Economic strength or subtle intrigues? A council seat… or a sharpened blade? The cards are dealt. The choice is yours. The Imperium awaits.

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.
