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
Build the highest garbage tower in Smelliville in our new app "THE OGGLIES"! Sounds oggly? Not that easy; the nasty builder Hammer keeps getting in your way with his demolition team and tries to make your painstakingly built tower collapse. Can you build the highest tower with the Oggly children and crack your high score? TRAINING FINE MOTOR SKILLS The garbage tower is built from different garbage objects, which are placed on the tower with simple gestures using a crane. Some skill is required here so that the building blocks are placed correctly, and the tower does not collapse. The children playfully learn physics and train their fine motor skills at the same time. HIGHLIGHTS: - Witty stacking game with the funny characters from the new movie THE OGGLIES - Special modules provide variety and confuse the laws of physics - Win new garbage items for your tower - Incl. mini-game "Oggly Baby's Special Attack" - No internet or WLAN required About Fox & Sheep: We are a Studio in Berlin and develop high quality apps for kids at the age of 2-8 years. We are parents ourselves and work passionately and with a lot of commitment on our products.

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.

Intermediate
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.
