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
From the makers of Peekaboo Barn comes the freshest—and healthiest—pop-up party! Who's having a party in your fridge? Open the door and find a fun-loving fruit, vegetable, or other delicious, healthy food. Learn the name of the food, watch it greet you, and dance along to a disco party! • Choose from two narrations: a child’s voice (cute and silly) or an adult narrator (perfect pronunciation) • Over a dozen fruits, veggies, and other foods are waiting to surprise your little one, in a different order each time • Fun, original music encourages kids to get up and dance with the characters in the fridge • Hear and see the word for each food, helping children with verbal skills and early literacy • Choose Looped Mode for endless play, or Regular Mode which ends with the characters going to sleep—perfect for bedtime! • Ideal for the youngest app users • Artwork and sound design by creative artists • Play anywhere: no wifi or internet necessary • Totally safe: no third-party advertising or in-app purchases.

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.
