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
More than a million people have relied on the words of Day by Day as an essential source of inspiration, spirituality, and mindfulness for their ongoing health and wellness. Reinforcing the Twelve Step principles of Narcotics Anonymous, each thought of the day in this classic collection fosters the coping skills, insights, and spiritual growth that have helped people around the world find freedom from drug dependency and addiction. Each daily message includes a reading, a question, and a prayer. Also included every day is an interactive “sentence starter” to help you think about and relate the daily topic to your own life. Use this as inspiration for journal writing or discussions, or type your thoughts right into the app. The Day by Day app also includes lists of the Twelve Steps and Twelve Traditions as well as the Prayer of Saint Francis. Features: PRESS the “Today” button to access today’s reading. SWIPE forward or back to easily access more daily readings. TYPE and save your answers to the daily sentence starters. SHARE the daily reading with friends by e-mail or text. BOOKMARK your favorite meditations (press the star in the upper right-hand corner) and easily return to them (press the star in the bottom toolbar). SEARCH all 366 daily readings. RECEIVE a notification every day to remind you to read the daily meditation. JUMP to a specific reading using the calendar button. SET your font size using your device settings. CHOOSE between light or dark mode.

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.
