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
Based on the spiritual foundation of Twelve Step programs, A Day at a Time offers inspiration and hope to those in recovery. Drawing upon insightful phrases often overheard in the rooms of recovery, the daily reflections and prayers in this best-selling app are intended to offer comfort and guiding reminders to those recovering from alcoholism, drug addiction, substance use disorders, process addictions, or any other compulsive behaviors. In addition to a reading for each day of the year, this app also includes the Twelve Steps and the Twelve Traditions of Alcoholics Anonymous. Recovery is a process that happens a day at a time, and the daily messages in this app will help support your journey. Features: PRESS the “Today” button to access today’s reading. SWIPE forward or back to easily access more daily readings. 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.
