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
The Field: Nikko's Journey is the official companion app to the book by Herb Perez and Nikko Perez. Follow 11-year-old Nikko as he learns that soccer — like every worthwhile path — is not something you can copy from someone else, even someone you love. This app brings the book to life with five powerful tools for young players: CHAPTERS Unlock all 10 chapters as you read. Each chapter includes the full koan, the parable summary, the lesson, and the Talk About It question. Complete each chapter to unlock the next one and track your journey from beginning to end. WORKBOOK JOURNAL Every chapter has a workbook with three reflection prompts — straight from the book. Write your answers, save them, and watch your journal grow as you move through Nikko's story. Your words. Your journey. TRAINING LOG Log every practice session with focus area, duration, star rating, and notes. Watch your total training hours grow over time. Every session counts. GOALS Set short-term and long-term goals with target dates. Check them off as you achieve them. The best players know where they are going — and they write it down. DAILY QUESTION Every day a koan from the book appears on your home screen. A single question to carry with you. Let it work on you. THE FIELD is for young players who want more than just skills. It is for players who want to understand themselves. Works completely offline. No account required. No ads. Just you and your journey. "Whose feet are you running on?"

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.
