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
Come explore Salem’s troubled history with us, on this 3.7 mile walk around town. The hysteria surrounding the witchcraft trials permeated every corner of the town in the late 1600’s. You’ll see where Giles Corey was pressed to death, where infamous judges lived and were buried, and where nineteen suspected witches were hanged. This narrated walking tour of historic Salem stops at 13 sites. Too spooked? Rain? Take a break and resume the tour later. It's like having your own personal guide, at a fraction of the price. Two Buck Tours have maps with GPS and a recommended route, photos, text, and audio narration (in English). Good for locals and tourists of all ages. No schedules, no crowds, no worries.

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.
