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
Brighten your day and invite creative introspection with this oracle deck of magical fairies. Created by artist, intuitive healer, and disabilities advocate Emily Anderson, these 100 charming characters encourage self-empowerment and positive thinking with an energy all their own. You can trust that just the right fairy will appear every time. Each fairy is a positive entity, carrying a message that aims to reach the space around your heart and hold it gently. From “Fairy of Grandmother Tree” to “Fairy of Not Doing and All Gets Done,” each contains the potential to shift your focus or perspective and lead to new insights. 'Fairy of the Day' originates with the daily drawing practice devised by Anderson to process life’s difficulties while living alone in the Vermont countryside. “As I began sharing the deck with others,” Anderson says, “people were amazed at how easily the fairies brought positivity and relevance to their lives.” With ‘Fairy of the Day,’ you can select multiple fairies every day and share the fairies’ wisdom with friends, family, and strangers. We've even heard of some meetings that begin with picking a Fairy of the Day! 'Fairy of the Day' offers a new way to connect in with yourself, each day. People all over the world are using the app to welcome joy into their lives. Join the community. ‘Fairy of the Day’ includes: • 100 original fairies to discover and get acquainted with • An active archive of your most recently selected fairies (up to 30) • Inspiration and suggestions for how to use ‘Fairy of the Day’

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.
