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
Curious about your family history? Add branches to your family tree with FamilySearch Tree, the world’s largest online family tree. FamilySearch Tree makes it easy and convenient to discover and document your own branches of the world’s family tree while preserving family memories, such as photos, written stories, and audio recordings. Harness the power of a worldwide, crowd-sourced pedigree to discover your family story. As you add information, FamilySearch will start searching for your family members while looking at historical records like birth and death certificates. Share information that others might not know, and add sources to confirm correct information. Update information and records easily so that everyone has accurate information. Browse your family tree branches, and see portraits of relatives you’ve never seen before. Discover facts, documents, stories, photos, and recordings about your ancestors. Easily add new life details, photos, stories, and audio recordings for your relatives. Find and share meaningful, heart-turning family stories that will make an impact on your life and the lives of your loved ones. Genealogy at Your Fingertips Family history has never been easier to track and build. Build your family tree by finding or adding family members directly through the app. Once you add a deceased relative to the family tree, FamilySearch will try to connect you to any information it has about that person in its database. Discover new family members and descendants in the community tree. Explore your heritage in maps that show where the key events of your ancestors’ lives took place. Ancestors, Relatives, and Family Find your ancestors in the billions of records on FamilySearch.org to learn more details of your family story.

Enhance your tree by adding photos, stories, and documents. Add sources to confirm correct information. Communicate and collaborate with other FamilySearch users from within the app with in-app messaging. Connect with family near and far. You may find a relative who has visited the same graves, asked the same questions about—and even learned to love or admire—the same ancestors. Watch your family tree grow. Discover family, learn your family history, and help map the family tree for mankind with FamilySearch Tree. NOTE: Content you provide for deceased individuals will be publicly available.

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.
