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
A game of teamwork and betrayal ...in space! Play online with 4-15 players as you attempt to prep your spaceship for departure, but beware as one or more random players among the Crew are Impostors bent on killing everyone. MASTER YOUR SOCIAL DEDUCTION SKILLS. Crewmates win by completing all tasks or discovering and voting the Impostors off the ship. The Impostor can use sabotage to cause chaos, making for easier kills and better alibis. Optional roles create a whole new level of gameplay. Try out the Scientist, Engineer, Guardian Angel, or Shapeshifter to create chaos! Think you’re a master of deception? Only one way to find out! CUSTOMIZE YOUR GAME. Choose how you want to play! Change the number of Impostors, roles, tasks, player visibility, and more. Play in style as you change your Crewmates’ color, visor, nameplate, outfit, and hat. More customization options are planned to be continually added in. PLAY WITH ANYONE. Cross-platform play is supported. Play with friends (or enemies?) between PC, mobile, or console!

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.
