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
The legendary Scary Maze has come on iPhone! The Scary Maze is not a real game but a scary prank for your friends. The best internet prank ever!! This app pretends to be a skill test. You must guide the blue dot through the scary maze with your finger. Clearing the maze on level 1 and 2 shouldn’t be hard, but level 3 requires skill to get past!! In the middle of level 3 a scary face appears unexpectedly with a terrified scream!!! Teste this app with your wife or your parents, and watch your “victim” reactions!! Use this application responsibly and only on people that you know well. This application must not be used with children, individuals with a heart condition, epileptic symptoms, ora any physical or mental condition. Use of this application is at your own risk, especially when someone tries to kick you after this prank Have fun By Dracoders

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.
