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
TimePassages Legacy is the previous version of our beloved astrology app. We’ve since launched a brand-new version of TimePassages with an enhanced user experience, modern graphics, and exciting new features like Solar Return charts and improved compatibility insights. We are maintaining TimePassages Legacy for a limited time to help our long-term users migrate seamlessly to the new app. If you are an existing TimePassages Pro customer, you’ll find an easy onboarding process within this app that guides you through transferring your account and data. Please note: TimePassages Legacy is no longer being actively updated, and its support will end on January 31, 2026. We recommend downloading the new TimePassages 3.0 app for the latest features and improvements.

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.
