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
High standards? Keep them that way. The League is a selective dating app offering its members a curated “Batch” of potentials each day, rather than an unlimited stream of profiles. Designed for motivated daters who would rather be single than settle, The League strongly believes that 3 quality matches are better than 100 bad ones. So say goodbye to endless swiping and keep those standards sky-high— because while your mother might call you picky, we call you self-aware. The League uses an application process to ensure a well-balanced, highly engaged community of people with real motivation to find a meaningful long-term relationship. You can use The League for free or upgrade to a subscription to unlock additional benefits. Subscribers see more profiles each day, and thus, enjoy 40% more matches on average. Subscription Details: Payment will be charged to Apple Account at confirmation of purchase. Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. Account will be charged for renewal within 24-hours prior to the end of the current period. Subscriptions may be managed and auto-renewal may be turned off by going to Account Settings after purchase.

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.
